&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the &#039;&#039;&#039;sfusehist&#039;&#039;&#039; parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [[Understand IFs#Standard Error Targeting| algorithm described elsewhere]].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs represents three dimensions of [[Governance#Governance|governance]]&amp;amp;nbsp;(security, capacity, and inclusion) and uses two sub-dimensions for each. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the &#039;&#039;&#039;sfusehist&#039;&#039;&#039; parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;
&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;The Inclusion Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [[Understand IFs#Standard Error Targeting| algorithm described elsewhere]].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;

Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs represents three dimensions of [[Governance#Governance|governance]]&amp;amp;nbsp;(security, capacity, and inclusion) and uses two sub-dimensions for each. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the &#039;&#039;&#039;sfusehist&#039;&#039;&#039; parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;
&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;The Inclusion Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:DEMOCPOLITYBase=basic or initial democracy using the Polity scale (in our case a combined 20-point scale built from historical democracy and autocracy series)&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [[Understand IFs#Standard Error Targeting| algorithm described elsewhere]].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs represents three dimensions of [[Governance#Governance|governance]] security, capacity, and inclusion) and uses two sub-dimensions for each. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;

In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Dominant Relations: Governance&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:Algorithm on regional contagion explained in text&lt;br /&gt;
&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the &#039;&#039;&#039;sfusehist&#039;&#039;&#039; parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:DEMOCPOLITYBase=basic or initial democracy using the Polity scale (in our case a combined 20-point scale built from historical democracy and autocracy series)&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [[Understand IFs#Standard Error Targeting| algorithm described elsewhere]].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:Algorithm on regional contagion explained in text&lt;br /&gt;
&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the &#039;&#039;&#039;sfusehist&#039;&#039;&#039; parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.)

&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;

:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:DEMOCPOLITYBase=basic or initial democracy using the Polity scale (in our case a combined 20-point scale built from historical democracy and autocracy series)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Dominant Relations: Governance&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Dominant Relations: Governance&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;
&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;

&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;

[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of past intrastate conflict, energy trade dependence (as a proxy for broader natural resource dependence), economic growth rate (inverse), youth bulge, urbanization rate, poverty level, infant mortality, life expectancy (inverse) undernutrition, HIV prevalence, primary net enrollment (inverse), adult education levels (inverse), corruption, democracy (inverse), gender empowerment (inverse), governance effectiveness (inverse), freedom (inverse), inequality, and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and social expenditures (that is, inversely to fiscal balance).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, youth bulge (inverse), and gender empowerment; although normally disabled in the model, neighborhood effects and global leadership can also affect democracy level.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and adult educational attainment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

where&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;

&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;The Inclusion Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;The Inclusion Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;

:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;

:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;

&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;The Inclusion Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;The Inclusion Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

:DEMOCPOLITYBase=basic or initial democracy using the Polity scale (in our case a combined 20-point scale built from historical democracy and autocracy series)&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;

= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Governance Flow Charts&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;

:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year.&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:POLITYDEMOC=Polity’s 21-point scale of democracy; asymmetrical curvilinear relationship with a peak at 9 and a sharper fall than rise&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:GDPRMA=gross domestic product growth rate, algorithmic moving average carrying forward 60 percent past year’s value; algorithmic adjustment with GDP/capita explained in text; inverse relationship&lt;br /&gt;
&lt;br /&gt;
:SFINTLWARMA=moving average of past internal war probability&amp;amp;nbsp; (i.e., carrying forward past forecast values, not past data values)&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:Algorithm on regional contagion explained in text&lt;br /&gt;
&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

:DEMOCPOLITYBase=basic or initial democracy using the Polity scale (in our case a combined 20-point scale built from historical democracy and autocracy series)&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by an endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADEOPEN_{r,t}=(X_{r,t}+M_{r,t})/GDP_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:POLITYDEMOC=Polity’s 21-point scale of democracy; asymmetrical curvilinear relationship with a peak at 9 and a sharper fall than rise&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;

&lt;br /&gt;
:&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. &lt;br /&gt;
&lt;br /&gt;
As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;

&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;

:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by a endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;

Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

:Algorithm on regional contagion explained in text&lt;br /&gt;
&lt;br /&gt;
:R-squared = 0.22 in 50-year historical simulation without annual correction (see text for elaboration)&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALLBase_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance. For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;

We have also computed multivariate functions (using GDP per capita and education as drivers) for the other four WGI measures, voice and accountability, political stability, corruption, and rule of law. But we have not yet added them to IFs.&lt;br /&gt;
&lt;br /&gt;
Turning to policy orientations, we compute an economic freedom variable based on the measures of the Economic Freedom Institute (with leadership from the Fraser Institute; see Gwartney and Lawson with Samida, 2000):&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;ECONFREE_{r,t}=(5.4097+0.5971ln(GDPPCP_{r,t}))*\mathbf{econfreem}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:DEMOCPOLITYBase=basic or initial democracy using the Polity scale (in our case a combined 20-point scale built from historical democracy and autocracy series)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by a endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:FREEDOM=freedom using 14-point Freedom House scale (PL and CL summed), inverted so that higher is more free&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for adults aged 15 or older&lt;br /&gt;

:&#039;&#039;&#039;freedomm&#039;&#039;&#039;=an exogenous multiplier for the model user&lt;br /&gt;
&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The most recent and complete governance model documentation is available on Pardee&#039;s [http://pardee.du.edu/ifs-governance-and-socio-cultural-model-documentation website]. Although the text in this interactive system is, for some IFs models, often significantly out of date, you may still find the basic description useful to you.&lt;br /&gt;
&lt;br /&gt;
Governance is the two-way interaction between government and the broader socio-political or, even more broadly, socio-cultural system. Although our documentation and the IFs model itself focuses primarily on three dimensions of that governance interaction, we will need also to direct some attention specifically to that broader socio-cultural system and how it might change over time.&lt;br /&gt;
&lt;br /&gt;
The conceptual foundation for the representation of governance in IFs owes much to an analysis of the evolution of governance in countries around the world over several centuries. That analysis (see Chapter 1 of the Strengthening Governance Globally volume by Hughes et al. 2014) identified three dimensions of governance: security, capacity, and inclusion. It traced them over time and noted their largely sequential unfolding for currently developed countries and their currently simultaneous progression in many lower-income countries.&lt;br /&gt;
&lt;br /&gt;
The three dimensions interact closely and bi-directionally with each other. They also interact bi-directionally with broader human development systems. The level of well-being, often captured quantitatively by GDP per capita or the more inclusive human development index, may be especially important, but is hardly alone in helping drive forward advance in governance; for instance, the age structures of populations and economic structures also interact with governance patterns both indirectly through well-being and directly.[[File:Gov1.jpg|frame|right|Visual representation of governance]]&lt;br /&gt;
&lt;br /&gt;
The conceptualization of governance further divides each of the three primary dimensions into two sub-dimensions partly based on the desire to quantify them historically and to facilitate forecasting. For security those are the probability of intrastate conflict and the general level of country performance and risk. The two sub-dimensions of capacity are the ability to raise revenue and the effective use of it and the other tools of government—that is, the competence or quality of governance. We use corruption (that is, control of it) as a proxy for such competence. The first sub-dimension of inclusion is the level of formal democratization, typically assessed in terms of competitive elections. More broadly democratization involves inclusion of population groupings across lines such as ethnicity, religion, sex, and age; we use gender equity as a proxy for the second dimension.&lt;br /&gt;
&lt;br /&gt;
See Hughes et al. (2014), especially Chapter 4, for more background on the development of the governance representations of IFs than this documentation provides. See also Hughes (2002) for earlier and/or complementary work in IFs on socio-political representations (domestic and international); for example, here we do not discuss the formulations for power, interstate threat, and conflict, but that is available in documentation on the International Political model of the IFs system. Finally, we do not provide here the important information about the forward linkages of governance to other elements of IFs, including to the production function of the economic model and to the broader financial flows of the social accounting matrix representation. See documentation on the economic model for that information.&lt;br /&gt;

&lt;br /&gt;
The drivers of change on each dimension and sub-dimension of governance range widely.&amp;amp;nbsp; A quick summary (see also the table below) is that:[[File:Gov2.png|frame|right|Drivers of change on each dimension and sub-dimension of governance]]&lt;br /&gt;
&lt;br /&gt;
*Probability of intrastate conflict is a function of past conflict, neighborhood effects, economic growth rate (inverse), trade openness (inverse), youth bulge, infant mortality, democracy (inverted-U), state repression (inverse), and external intervention (inverse).&lt;br /&gt;
*Vulnerability to intrastate conflict is a function of energy trade dependence, economic growth rate (inverse), urbanization rate, poverty level, infant mortality, undernutrition, HIV prevalence, primary net enrollment (inverse), intrastate conflict probability, corruption, democracy (inverse), governance effectiveness (inverse), freedom (inverse), and water stress.&lt;br /&gt;
*Government revenues are a function of past revenue as percentage of GDP, GDP per capita, and fiscal balance (inverse).&lt;br /&gt;
*Corruption is a function of past corruption level, GDP per capita (inverse), energy trade dependence, democracy (inverse), gender empowerment (inverse), and probability of intrastate conflict.&lt;br /&gt;
*Democracy is a function of past democracy level, economic growth rate (inverse), youth bulge (inverse), and gender empowerment.&lt;br /&gt;
*Gender empowerment is a function of past gender empowerment level, GDP per capita, youth bulge (inverse), and primary net enrollment.&lt;br /&gt;
&lt;br /&gt;
There are some general insights with respect to elaboration of the formulations (equations and algorithms) that drive change on each dimension and sub-dimension of governance:&lt;br /&gt;
&lt;br /&gt;
*In almost each case there are path dependencies that supplement the basic relationships—social change has considerable inertia.&lt;br /&gt;
*The driving and driven variables clearly constitute a complex syndrome of mutually interdependent developmental interactions, not a simple causal sequence.&lt;br /&gt;
*There is a tendency for the dimensions of governance traditionally developing later to feed back to earlier ones, notably for inclusion to affect capacity via reduced corruption and also for inclusion and capacity to reduce the probability of internal conflict.&lt;br /&gt;
*Behaviorally, the bi-directional structures suggest the possibility that reinforcing processes may accelerate as governance strengthens, setting up a kind of tipping from one equilibrium to another; vicious cycles of deterioration would also be possible.&lt;br /&gt;
&lt;br /&gt;
For detailed discussion of the model&#039;s causal dynamics, see the discussions of flow charts (block diagrams) and equations.&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
We can show and briefly describe a block diagram for each of the three dimensions of governance and the two sub-dimensions of those: security (probability of intrastate or internal war and risk of conflict); capacity (ability to mobilize revenues and the effectiveness of their use); inclusiveness (formal democracy and broader inclusiveness, using gender empowerment as a proxy).&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Security&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Internal War&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Internal or intrastate war (SFINTLWAR) is heavily determined by a moving average of a society&#039;s past experience with such conflict (SFINTLWARMA) in what is a positive feedback system. The probability of such conflict will, however, typically converge to that determined by more basic underlying drivers, and the user can control the speed of such convergence by specifying the years to convergence (&#039;&#039;&#039;&#039;&#039;sfconv&#039;&#039;&#039; &#039;&#039;).[[File:Gov3.jpg|frame|right|Visual representation of internal war]]&lt;br /&gt;
&lt;br /&gt;
The major driving variables in a statistical estimation are the level of infant mortality (INFMORT) as a proxy for quality of government performance and trade openness or exports (X) plus imports (M) as a share of GDP. In addition democracy level (DEMOCPOLITY) enters in a non-linear and algorithmic fashion, as do youth bulge (YTHBULGE) and a moving average of economic growth rate (GDPRMA).&lt;br /&gt;
&lt;br /&gt;
Although less often used and turned off in the Base Case scenario, external interventions (&#039;&#039;&#039;&#039;&#039;wpextinterv&#039;&#039;&#039; &#039;&#039;) and mass repression (&#039;&#039;&#039;&#039;&#039;sfmassrep&#039;&#039;&#039; &#039;&#039;) can cause or at least temporarily dampen internal war, respectively.&lt;br /&gt;
&lt;br /&gt;
Finally, the user can multiply resultant endogenous values of internal war (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in order to generate user-controlled scenarios.&lt;br /&gt;
&lt;br /&gt;
The IFs system also includes a representation of instability short of internal war (&#039;&#039;&#039;SFINSTABALL&#039;&#039;&#039; and &#039;&#039;&#039;SFINSTABMAG&#039;&#039;&#039;), linking them to the category of abrupt regime change in the classification developed by Ted Robert Gurr and used by the Political Instability Task Force. The forecasting representation was developed before the revision and update of that for internal war, however, and we recommend less attention to it until its own revision is done.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Vulnerability and Risk of Conflict&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The IFs treatment of societal/governance performance risk and related vulnerability to conflict does not involve an estimated formulation. Instead, like other such efforts, it involves the creation of an index. The figure below, a screen capture of the form (reached via Specialized Displays) uses variables related both directly to governance and to performance. A [[Governance#Performance_Risk_Analysis_Form|specialized Help topic]] on this form is available.&lt;br /&gt;
&lt;br /&gt;
Although many users will be interested in the rankings of countries (see the Global Rank column for ranks on individual variables and the summary measure for overall, variable-weighted rank), others will be interested in the summary value across all variables, shown at the bottom of the first column. Those values are also available in the model as the variable named government risk (GOVRISK).&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|1035x690px|Variables related both directly to governance and to performance]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Capacity&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Government Revenues&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The ability to raise government revenues (GOVREV as a share of GDP) is one of the dimensions of capacity in governance. Its basic calculation is a very simple ratio. The key drivers of GOVREV, however, documented [[Governance#Equations:_Broader_Regime_Capacity|elsewhere]], are very complex. For instance, GOVREV is responsive in an equilibration process to government expenditures, both transfer payments and direct government expenditures in categories such as military, health, education, and infrastructure, as well as to external revenues, notably foreign aid receipts.[[File:Gov42.jpg|frame|center|Visual representation of government revenues]]&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Effectiveness of Government&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The central measure of governance effectiveness in Hughes et al. (2014) was defined to be corruption or GOVCORRUPT (actually the absence thereof, or level of transparency). The model computes several additional measures of effectiveness or capacity, however, including regulatory quality (REGQUALITY) and effectiveness (GOVEFFECT), both related to the World Bank&#039;s World Governance Indicator project (Kaufmann, Kraay, and Mastruzzi 2010). In addition, many analysts point to the level of economic freedom (ECONFREE) or liberalization as a measure of effectiveness, in spite of considerable debate around their doing so.&lt;br /&gt;
&lt;br /&gt;
Among the drivers of governance corruption is resource dependence, for which we use as a proxy the value of energy exports (ENX) at energy prices (ENPRI) as a share of GDP. Energy exports tend to be the largest such category globally. Further drivers are the extent of gender empowerment (GEM) and the level of democracy (DEMOCPOLITY), both of which indicate the extent of inclusiveness but which make independent statistical contributions to corruption level.[[File:Gov5.jpg|frame|right|Visual representation of government effectiveness]]&lt;br /&gt;
&lt;br /&gt;
The drivers do not, of course, fully determine the level of corruption and there is much historical path dependence in societies related to other variables. The user can control the speed of elimination of such dependence and therefore of convergence to the basic formulation with a conversion years parameter (&#039;&#039;&#039;&#039;&#039;goveffconv&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the [[Understand_IFs#Standard_Error_Targeting|specification of a target level]] 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. There are similar control parameters (not shown the diagram) for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Theoretically, internal war (SFINTLWAR) could affect all of the capacity variables, but the only linkage identified in IFs is that to economic freedom. Setting the control switch (&#039;&#039;&#039;&#039;&#039;confforsw&#039;&#039;&#039; &#039;&#039;) to 1 turns on that impact.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Inclusiveness&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Democracy&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Three variables dominate the forecasting [[Governance#Equations:_Gender_Empowerment|formulation for democracy]] (DEMOCPOLITY): the gender empowerment measure (GEM) as a measure of broad social inclusion (positive linkage), the youth bulge (YTHBULGE) as an indicator of the age structure of society (negative linkage), and the dependence of the country on raw materials exports, a negative linkage using energy export share (ENX) times energy prices (ENPRI) as a share of the GDP as a proxy. An exogenous multiplier (&#039;&#039;&#039;&#039;&#039;democm&#039;&#039;&#039; &#039;&#039;) allows the user to directly manipulate the democracy level.[[File:Gov6.jpg|frame|right|Visual representation of democracy]]&lt;br /&gt;
&lt;br /&gt;
Two other variables can affect the democracy level but are turned off in the Base Case and will seldom be used. The first is the neighborhood effects of swing states in a regional neighborhood (e.g. Russia among former states of the Soviet Union). The swing states effect switch (&#039;&#039;&#039;&#039;&#039;sweffects&#039;&#039;&#039; &#039;&#039;) turns it on when set to 1.&lt;br /&gt;
&lt;br /&gt;
The more complicated additional factor is that of democracy waves (DEMOCWAVE). Relative to the initial condition a democracy wave can add or subtract democracy to the basic formulation&#039;s calculation of it (an algorithm based on historical experience allows upward swings to be larger than downward ones depending on EffectMul). The basic magnitude of increments depends of an exogenous specification of the impetus provided to democracy by the leading power (&#039;&#039;&#039;&#039;&#039;democwvus&#039;&#039;&#039; &#039;&#039;) and by other powers (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;), the former&#039;s impact controlled by an elasticity (&#039;&#039;&#039;&#039;&#039;eldemocimp&#039;&#039;&#039; &#039;&#039;). Because waves rise and ebb, another parameter controls the length (&#039;&#039;&#039;&#039;&#039;democlen&#039;&#039;&#039; &#039;&#039;) and still another sets the maximum rise (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;). A counter keeps track of the running and receding of a wave (DEMOCWVCOUNT) and a pointer keeps track of the direction its operation (DEMOCWVDIR); these two parameters are linked with the magnitude of the wave in a positive loop.&lt;br /&gt;
&lt;br /&gt;
The calculation from the basic formulation, before the addition of wave and swing state or neighborhood effects, can also be overridden by the use of [[Understand_IFs#Standard_Error_Targeting|external targeting]] directed by specifications of standard error targets relative to the formulation (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) to be achieved by a target year (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Gender Empowerment and Freedom&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
[[Governance#Equations:_Gender_Empowerment|Gender empowerment (GEM)]], a broader measure of inclusion, joins democracy as the second key measure of governance inclusiveness. Its three basic drivers are youth bulge size (YTHBULGE), GDP per capita as purchasing power parity (GDPPCP), and the years of formal education obtained by female adults (EDYRSAG15).&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.[[File:Gov7.jpg|frame|center|Visual representation of gender empowerment and freedom]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Aggregate Governance Indicators&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The major way of exploring the possible future of the three dimensions of governance is separately to use the two variables that represent each. But it is also useful to have more aggregate indices, first for each dimension and also across the three.&lt;br /&gt;
&lt;br /&gt;
The governance security index (GOVINDSECUR) is computed as an unweighted average of internal war probability (SFINTLWAR) and governance/society performance risk (GOVRISK). Similarly, the governance capacity index (GOINDCAP) is an unweighted average of government revenue (GOVREV) as a portion of GDP and government corruption, while the governance inclusion index (GOVINCLIND) averages democracy (DEMOCPOLITY) and gender empowerment (GEM). The overall governance index (GOVINDTOTAL) is a simple average of those across dimensions.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov8.jpg|frame|center|Visual representation of governance index]] In reality, creating the indices for each dimension requires some attention to scaling issues and valence. See the description of the equations for details.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Life Conditions and the Human Development Index&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The condition of individuals and society are both the ultimate focus of governance and the font of it. The IFs system computes many of the relevant variables across its various models. It also aggregates a number of those into the widely used Human Development Index (HDI), based on heath (life expectancy), education or knowledge (both expectations for youth and attainment for adults), and GDP per capita.&lt;br /&gt;
&lt;br /&gt;
[[File:Gov9.png|frame|center|Visual representation of life conditions and HDI]]&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Social Values and Cultural Evolution&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Understanding societies fully requires going even more deeply than their governance and social conditions in order to look at the values and cultural foundations. IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism, survival/self-expression, and traditional/secular-rational values.&lt;br /&gt;
&lt;br /&gt;
Inglehart has identified large cultural regions that have substantially different patterns on these value dimensions and IFs represents those regions, using them to compute shifts in value patterns specific to them.&lt;br /&gt;
&lt;br /&gt;
Levels on the three cultural dimensions are predicted not only for the country/regional populations as a whole, but in each of 6 age cohorts. Not shown in the flow chart is the option, controlled by the parameter &amp;quot;&#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;,&amp;quot; of computing country/region change over time in the three dimensions by functions for each cohort (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 1) or by computing change only in the first cohort and then advancing that through time (value of &#039;&#039;&#039;&#039;&#039;wvsagesw&#039;&#039;&#039; &#039;&#039;= 2).&lt;br /&gt;
&lt;br /&gt;
The model uses country-specific data from the World Values Survey project to compute a variety of parameters in the first year by cultural region (English-speaking, Orthodox, Islamic, etc.). The key parameters for the model user are the three country/region-specific additive factors on each value/cultural dimension (&#039;&#039;&#039;&#039;&#039;matpostradd&#039;&#039;&#039; &#039;&#039;, etc.).&lt;br /&gt;
&lt;br /&gt;
Finally, the model contains data on the size (percentage of population) of the two largest ethnic/cultural groupings. At this point these parameters have no forward linkages to other variables in the model.&amp;amp;nbsp;[[File:Gov10.png|frame|center|Visual representation of social values and cultural evolution]]&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Like the block diagrams for governance in IFs, the equations fall into the categories of the three dimensions (security, capacity, and inclusion), with detail for each of two sub-dimensions on each.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Security Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
IFs represents two different types of measures related to domestic conflict and security. The first has roots in the work of the Political Instability Task Force (PITF); see Esty et al. (1998) and Goldstone et al. (2010). The PITF database allows us to see the actual pattern of conflict in countries over time and to use that historical conflict pattern to compute an initial probability of conflict. The second type of measure includes indices of vulnerability to conflict, generally presented in terms of rankings of countries with respect to their vulnerability (see Chapter 2 of Hughes et al. 2014, especially Box 2.3). Because these indices are not rooted as solidly in past conflict patterns, we cannot interpret their values or the rankings based on them as probabilities of conflict, but rather as propensities for conflict (and as indicators more generally of country performance and risk).&lt;br /&gt;
&lt;br /&gt;
In order to establish forecasting approaches for both types of measures within IFs, we looked to earlier work (see Chapter 3 of Chapter 2 of Hughes et al. 2014), did our own statistical analysis to create an underlying base formulation for overt conflict probability, and augmented the basic approach via more algorithmic elements—algorithms or logical procedures, like recipes, help guide forecasting through steps that analytical functions cannot easily represent. The algorithmic elements are tied in part to our efforts to fit the IFs forecasting approach at least relatively well to historical data from 1960 through 2010. Chapter 4 of Hughes et al. 2014 elaborates more fully the development process for the representation of security provided in this Help system.&lt;br /&gt;
&lt;br /&gt;
=== Equations: Internal Conflict or War Probability ===&lt;br /&gt;
&lt;br /&gt;
The PITF defined state failure in terms of four different types of events (with specific magnitude thresholds)—namely, adverse regime change (such as coups), revolutionary wars, ethnic wars, and genocides or politicides (Esty et al. 1998). On the recommendation of Ted Robert Gurr, one of the founding fathers of the PITF data project and approach, IFs builds two categories of insecurity from those four types: instability (adverse regime change); and internal war (combining revolutionary war, ethnic war, and genocide or politicide).&lt;br /&gt;
&lt;br /&gt;
Presence of any one of the three types of war, either as an initiation or continuation, leads us to code a country as 1; otherwise we code the country as 0. This distinction between instability and internal war helps differentiate among what Easton (1965) identified as regime, state, and polity levels within the sociopolitical system, by at least differentiating the regime level (where adverse regime changes occur) from the more fundamental state and polity levels. The forces of change and generally the extent of violence around change differ significantly at these different levels.&lt;br /&gt;
&lt;br /&gt;
Looking at the historical patterns of conflict in global regions across time (see Chapter 4 of Hughes et al. 2014) and doing our own statistical analysis it is clear that the &amp;quot;usual suspect&amp;quot; variables will not explain those patterns, and that in many cases they cannot therefore be very effective in forecasting. We found:&lt;br /&gt;
&lt;br /&gt;
*Normed infant mortality proves statistically interesting, being associated with (explaining or being explained by, using a second-order polynomial form) about 12 percent of cross-country variation in intrastate conflict in the most recent data-year (8.9 percent in panel analysis across the 1960–2000 period). Thus in forecasting it may help us understand general propensity for conflict, but its slow variation over time means it cannot possibly explain the big historical surges of warfare within regions and their country members.&lt;br /&gt;
&lt;br /&gt;
*Trade openness (which we define as the sum of exports and imports as a percentage of GDP) can be helpful in understanding variations in conflict and does vary within countries more rapidly than infant mortality. In cross-sectional analysis with most recent data, infant mortality and trade openness (inverse relationship) together account for 15 percent of the variation in intrastate conflict (trade openness itself is associated with 11 percent of the variance within intrastate conflict in a logarithmic formulation). Moreover, its increase coincides with the reduction of conflict historically within the countries of East Asia. But openness perversely increased over time in South Asia as intrastate conflict also rose. And its statistical power is good but not great. Again, causality could run in either direction or be a spurious result of a third variable; for instance, the end of Indochina wars and a change in economic policy in socialist countries could have led to greater trade there.&lt;br /&gt;
&lt;br /&gt;
*Factionalism, which can have many bases, including ethnicity or the intensity of feelings around ethnicity, is of surprisingly little use in forecasting. Most underlying social divisions change very slowly over time. Although intensity of factionalism around those divisions may change much more rapidly (for instance, as &amp;quot;conflict entrepreneurs&amp;quot; inflame passions), we arguably cannot anticipate when that might happen. Nor do we believe we can we anticipate changes in other potential ideational drivers, such as ideologies. Further, historical measurement of change in factionalism risks using conflict as a proxy, thereby creating the danger that correlations between it and conflict are simply a tautological artifact of that measurement. Finally, our own analysis of various measures of ethnic and/or religious factionalism and intrastate conflict suggests lower relationship than we expected.&lt;br /&gt;
&lt;br /&gt;
*Youth bulges are a potentially more useful driver in forecasting because our demographic forecasts are stronger than those of variables like factionalism or even trade openness, and because demographic structures exhibit clear and non-monotonic variation over time. There were many bulges in East Asia during the 1970s, as there have been many recently in South Asia and as there are today in the Middle East and North Africa. In cross-sectional analysis of recent data, a linear relationship with youth bulge size accounts for 7 percent of the variation in conflict (in panel analysis since 1960, however, only 3.5 percent).&lt;br /&gt;
&lt;br /&gt;
*Consistent with studies that have found anocracy rather than autocracy primarily related to conflict, the relationship of measures of regime type with conflict has an inverted U-shaped character. Using a third-order polynomial, we found that the Polity measure of regime type explains 4 percent of variation in recent intrastate war. The Freedom House measure&amp;amp;nbsp;(see [http://www.freedomhouse.org/ http://www.freedomhouse.org/]) actually explains 10 percent, but we used the Polity Project measure (see [http://www.systemicpeace.org/polity/polity4.htm http://www.systemicpeace.org/polity/polity4.htm])&amp;amp;nbsp;because it is a purer measure of political democracy (rather than civil liberties as well) and because it is our primary measure of regime in forecasting.&lt;br /&gt;
&lt;br /&gt;
*Downturns in economic growth rates preceded the collapse of communism in Europe and Central Asia, the rise of internal conflict in both Latin America and the Middle East in the 1980s, and more recently the events of the Arab Spring. Analysis of the magnitude of downturn required to generate conflict and the lag between downturn and conflict is complex. We found, through experimentation directed at fitting historical conflict patterns (running IFs against historical patterns since 1960), that a 1.0 percent drop in a moving average of economic growth (carrying 60 percent of the moving average forward) is associated with a 0.04 point increase on a 0-1 scale for the rate of internal war.&lt;br /&gt;
&lt;br /&gt;
*Conflict begets conflict. We found, again through historical analysis, a 60 percent carryover of past conflict levels to current ones.&lt;br /&gt;
&lt;br /&gt;
For IFs forecasting, we conceptualize and operationalize intrastate war not as a 0 or 1 outcome as in the data (no war or war), but as a probability of conflict in any country-year. We initialize country probabilities at the beginning of a forecast horizon with average conflict rates across the preceding 20 years. The development of our own basic forecasting formulation for these probabilities involved not just literature and statistical analysis, but testing of the formulation in runs of the model from 1960 through 2010 and comparisons of our historical forecasts with the data on intrastate war. We let the historical forecasts run without the frequently used annual adjustment/correction by the historical conflict data for the full 50 years. We experimented with a number of algorithmic elements in order to improve the historical fit. This analysis yielded the following basic formulation:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINTLWAR_{r,t}=((0.1420+0.0012*INFMOR_{r,t}-0.0006*TRADEOPEN_{r,t})+F(POLITYDEMOC_{r,t},YTHBULGE_{r,t},GDPMA_{r,t},SFINTLWARMA_{r,t}))*\mathbf{sfintlwarm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
Our historical and extended analytical explorations of the core statistical formulation with infant mortality and trade openness led us to make a number of algorithmic changes to it in creating our basic formulation. We found that $18,000 per capita (in 2005 dollars at PPP) is a point above which economic downturns and youth bulges tend not to increase the probability of internal war, so we greatly dampened the affects of both of those variables above that level. We also found it important to add a regional contagion effect; courtesy of data provided by Paul Diehl we combined three of the Correlates of War Project distance categories (contiguous, less than 12 miles separation, and less than 24 miles separation) and added 0.1 to conflict probability for a country for each neighbor with computed conflict probability of its own above 0.2— because of conflict carryover across time, this algorithm can also lead to a positive feedback loop of neighborhood contagion.&lt;br /&gt;
&lt;br /&gt;
We further found that the intrastate war formulation is sensitive to actual GDP levels, not just because of the growth rate term, but because within the broader IFs system GDP per capita also affects the endogenously calculated youth bulge and democracy variables (we will return to discussion of the latter). To deal with this sensitivity, we forced the IFs historical base to be historically accurate with respect to GDP growth—otherwise the entire historical forecast of IFs after 1960 was endogenously determined in recursive annual calculation only by initial conditions and formulations rather than with annual corrective terms often used in historical validation exercises.&lt;br /&gt;
&lt;br /&gt;
This basic initial formulation generated a pattern of historical forecasts (which can be generated using the file HistoricalNoMassRepOrExtInterv.sce) of intrastate warfare probabilities that showed some of the characteristics of the historical data, including a peak for the Middle East and North Africa in the 1980s and one for developing Europe and Central Asia in the early 1990s (both related to growth downturns). Visual comparison quickly suggested, however, that the overall pattern was not a good historical fit. In particular, the bulges of conflict in East Asia in the early years and of South Asia more recently were missing; in addition, because of the infant mortality and economic growth terms, the model generated a bulge of conflict within Africa in the early 1980s (when growth and social advance was very weak) that did not appear in the data. Moreover, statistically, the forecasts correlated at the region level with data across the 1960-2010 time period with only a 0.19 R-squared level.&lt;br /&gt;
&lt;br /&gt;
We therefore explored the bases of the historical patterns further, and concluded that additional factors were missing. One is the extreme or totalitarian repression that lowered conflict in developing Europe and Central Asia until about the time of General Secretary Mikhail Gorbachev; we added a repression parameter (wpextinterv) for exogenous manipulation. More controversially perhaps, we also found it necessary to extend the suppression of conflict to sub-Saharan Africa in the middle period of the historical run; the underlying assumption is that the domestic prestige and power of liberation movement leaders, backed by their domestic and superpower supporters, helped dampen conflict significantly in the face of poor, and even deteriorating, domestic economic and social conditions.&lt;br /&gt;
&lt;br /&gt;
A second type of factor missing in our basic statistical analysis is external interventions, such as those of the U.S. in Southeast Asia in the 1960s and those of the former USSR and then the U.S. in South Asia after 1980; we added another exogenous parameter (sfmassrep) to represent such interventions.&lt;br /&gt;
&lt;br /&gt;
Although still not a terribly strong match to actual history, this revised historical forecast some remarkable similarities, including the initially high level of conflict in East Asia and the Pacific and a relatively high rate for South Asia in recent decades. The adjusted R-squared rises to 0.61 from 0.19 (before the addition of the repression and intervention variables). The major problems that remained in our historical forecast include the generation by the model of too much conflict for Latin America and the Caribbean in the 1980s, when economic and social conditions in that region deteriorated significantly; and the relatively high levels of conflict in sub-Saharan Africa beyond the end of the Cold War, again associated in our forecast with a combination of absolute and relative deterioration in socioeconomic conditions of many countries. Thus the additional parameters may be useful in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
It is possible that our relatively high historical forecasts for conflict in post-Cold War sub-Saharan Africa, even after formulation enhancements, may reflect the remaining omission of yet another systemic variable, namely regional and global efforts to dampen conflict there. There is no parameter to represent that variable, but the user can use the overall multiplier (&#039;&#039;&#039;&#039;&#039;sfintlwarm&#039;&#039;&#039; &#039;&#039;) in scenario analysis.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Political Stability/Instability&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The State Failure project has analyzed the propensity for different types of state failures within countries, including those associated with revolution, ethnic conflict, genocide-politicide, and abrupt regime change (using categories and data pioneered by Ted Robert Gurr. Upon the advice of Gurr, IFs groups the first three as internal war and the last as political instability. The model formulations for political instability are older and less well developed than those for internal war; we therefore recommend focus on internal war. Nonetheless, we document the approach to instability here.&lt;br /&gt;
&lt;br /&gt;
The extensive database of the project includes many measures of failure. IFs has variables representing the probability of the first year or a continuing year of instability (SFINSTABALL) and the magnitude of a first year or continuing event (SFINSTABMAG).&lt;br /&gt;
&lt;br /&gt;
Using data from the State Failure project, formulations were estimated for each variable using up to five independent variables that exist in the IFs model: democracy as measured on the Polity scale (DEMOCPOLITY), infant mortality (INFMOR) relative to the global average (WINFMOR), trade openness as indicated by exports (X) plus imports (M) as a percentage of GDP, GDP per capita at purchasing power parity (GDPPCP), and the average number of years of education of the population at least 25 years old (EDYRSAG25). The first three of these terms were used because of the state failure project findings of their importance and the last two were introduced because they were found to have very considerable predictive power with historic data.&lt;br /&gt;
&lt;br /&gt;
The IFs project developed an analytic function capability for functions with multiple independent variables that allows the user to change the parameters of the function freely within the modeling system. The default values seldom draw upon more than 2-3 of the independent variables, because of the high correlation among many of them. Those interested in the empirical analysis should look to a project document (Hughes 2002) prepared for the CIA&#039;s Strategic Assessment Group (SAG), or to the model for the default values.&lt;br /&gt;
&lt;br /&gt;
One additional formulation issue grows out of the fact that the initial values predicted for countries or regions by the six estimated equations are almost invariably somewhat different, and sometimes quite different than the empirical rate of failure. There may well be additional variables, some perhaps country-specific, that determine the empirical experience, and it is somewhat unfortunate to lose that information. Therefore the model computes three different forecasts of the six variables, depending on the user&#039;s specification of a state failure history use parameter (sfusehist). If the value is 0, forecasts are based on predictive equations only. The equation below illustrates the formulation. The analytic function obviously handles various formulations including linear and logarithmic.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=0 &amp;lt;/math&amp;gt; then (no history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=PredictedTerm_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t, Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 1, the historical values determine the initial level for forecasting, and the predictive functions are used to change that level over time. Again the equation is illustrative.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=1&amp;lt;/math&amp;gt; then (use history)&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=\frac{PredictedTerm_{f,t}}{PredictedTerm_{f,t=1}}*\mathbf{SFINSTABALL}_{r,t=1}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;PredictedTerm_{r,t}=ANALFUNC(GDPPCP_{r,t},DemocTerm_t,InfMorTerm_t,TradeTerm_t,Educ25Term_t)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocTerm=DemoPolity_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;InfMorTerm=\frac{INFMOR_r}{WINFMOR}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TradeTerm=\frac{X_r+M_r}{GDP}*100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;Educ25Term=EDYRSAG25_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
If the value of the sfusehist parameter is 2, the historical values determine the initial level for forecasting, the predictive functions are used to change the level over time, and the forecast values converge over time to the predictive ones, gradually eliminating the influence of the country-specific empirical base. That is, the second formulation above converges linearly towards the first over years specified by a parameter (polconv), using the CONVERGE function of IFs.&lt;br /&gt;
&lt;br /&gt;
:if &amp;lt;math&amp;gt;\mathbf{sfusehist}=2&amp;lt;/math&amp;gt; then (converge)&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
:&amp;lt;math&amp;gt;SFINSTABALL_{r,t}=ConvergeOverTime(SFINSTABALLBase_{r,t},PredictedTerm_{f,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Vulnerability to Conflict (and Performance Risk Analysis)&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The second approach to analyzing risk of violent internal conflict (and broader country risks) involves the creation of indices that tend to rank states according to generalized performance. The projects creating such indices—variously referred to as measures of state fragility, state weakness, political instability, or failed states—most often do not intend to convey a probability of violent internal conflict. Rather they try to suggest greater or lower propensities for conflict as well as broader country risk, for instance that which foreign investors might face with respect to socioeconomic conditions. .&lt;br /&gt;
&lt;br /&gt;
Generally, these indices combine variables in four categories: social, political, economic, and security. Developers may supplement variables that mostly focus on the average values for countries with select variables focusing on distribution (such as the Gini index). They commonly weight variables within categories equally and/or weight the categories equally when aggregating them to final index values. While individual variables have theoretical and empirical links to conflict or lack of security, such simple combination of large numbers of highly intercorrelated variables into a formulation of conflict vulnerability is very difficult to interpret. Moreover, because reports generally present an index with no simple interpretation of scale, analysts focus heavily on rankings of countries.&lt;br /&gt;
&lt;br /&gt;
The IFs project has created its own Performance Risk Index (see variable GOVRISK) along the lines of these approaches, and for the purposes of forecasting has uniquely made it responsive to endogenous long-term change in the underlying variables. Like those of other projects, the IFs measure draws upon social, political, economic, and security variables, but we impose a different conceptual or analytical structure on them (see the example risk analysis form provided here). We divide the variables of the index into three general categories: governance, (deep) risk drivers, and performance. We further divide the governance variables into our three dimensions of security, capacity and inclusion, the deep risk factors into demographic, environmental, and international categories, and the performance factors into economic, health, and education categories.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart11.png|frame|center|1080x728px|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
The Performance Risk Index (GOVRISK) and the probability of intrastate conflict (SFINTLWAR) provide quite different images of security in states, in part because the probability of intrastate war has a power-law distribution across countries and risk indices have a more nearly linear distribution (see Chapter 2 of Hughes et al 2014). In 2010 the correlation between the two measures in IFs has an adjusted R-squared of only 0.25. Presumably the probability of conflict measure should be the better indicator of its likelihood. In fact, beyond their drawing our attention to the highest ranked and therefore most fragile countries, risk indices seldom are used to identify conflict likelihood and more often suggest a wider variety of risks, including overall poor state performance, only some of which may be so severe as to lead to conflict.&lt;br /&gt;
&lt;br /&gt;
Because vulnerability or risk indices often include GDP per capita or other highly correlated indicators, they generally assign greater risk to poorer countries. Another way of using such risk information it to compare performance of countries to expectations that control for their level of GDP per capita (with a cross-sectional analysis). The column in the Performance Risk Analysis form showing standard errors helps us do that. In 2010 Angola&#039;s performance on infant mortality was 2.4 standard errors worse than the expected value. Thus its performance on that variable was not only very poor relative to other countries around the world, but also relative to countries at its own income level.&lt;br /&gt;
&lt;br /&gt;
Unlike our analysis with the probability of conflict, it is not possible to compare the IFs Governance Risk Index with other measures across the full 1960–2010 historical time period, because those other measures tend to be quite recent and to cover only a small number of years. For instance, the Brookings Institution&#039;s Index of State Weakness for the Developing World (Rice and Patrick 2008) was produced only for a single year (2008). The measures with the greatest time series are the Fund for Peace&#039;s Index of State Failure (2005–2012) and the Center for Systemic Peace&#039;s (CSP&#039;s) State Fragility Index (1995-2011); see Marshall and Cole 2008; 2009; 2011). In order to assess the risk index of IFs, we again did a historical run of the model, without any extraordinary interventions, from 1960 through 2010—the run computes the IFs Country Performance Risk Index for all years. The R-squared of 0.71 indicates the remarkably close correlation, even after 50 years of forecasting with the full integrated IFs model. In fact, the R-squared is 0.70 across all years for which the SFI is available.&lt;br /&gt;
&lt;br /&gt;
For much more detail on the structure and computations of the Performance Risk Analysis form, see the separate discussion of it (see [[Governance#Performance_Risk_Analysis_Form|Performance Risk Analysis Form]]).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Capacity Dimension&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
The capacity dimension has two primary elements. The first is the ability to raise revenue. The second is the effective use of it and the other tools of government—that is, the competence or quality of governance.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Government Finance&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Government finance in IFs sits within a broader [[Economics#Social_Accounting_Matrix_Approach_in_IFs|social accounting matrix (SAM) structure]] that accounts for, and in the process balances, all domestic and international financial exchanges among firms, households, and governments. The IFs system is unique, not only in the representation of flows within and across so many countries of the world, but also in maintaining, insofar as the sparse data allow, stocks (accumulations of net flows, such as government debt and assets of firms) that provide signals for equilibration processes that require changes in flows (like [[Economics#Government_Revenue|revenues]]&amp;amp;nbsp;and [[Economics#Government_Expenditure|expenditures]]) over time. Like the goods and services markets of the economic model, the government finance representation in IFs (its representation of revenues and expenditures) does not seek an exact equilibrium in every time point, but rather [[Economics#Government_Balances_and_Dynamics|chases equilibrium over time]]. The variables computed (see the links) are GOVREV, GOVEXP (with direct government consumption or GOVCON as a subset), and GOVBAL. This approach is both more realistic and more computationally efficient.&lt;br /&gt;
&lt;br /&gt;
The desired IFs treatment of government is of consolidated or general government. Beyond our use of the OECD&#039;s general government expenditure data for its members, however, our main data source for finance is the World Bank&#039;s World Development Indicators (Kaufmann, Kraay, and Mastruzzi 2010), which appear to provide mostly data for central government. In fact, for most countries there are quite incomplete and inconsistent systems of national accounts on which to build social accounting matrices generally, or a full mapping of government finance more specifically. Thus the &amp;quot;preprocessor&amp;quot; in IFs plays a big role in creating a consistent and complete initial image of government finance.&lt;br /&gt;
&lt;br /&gt;
With respect to government finance and the SAM more generally, the preprocessor both fills holes for missing data series of many countries, using cross-sectionally estimated functions or algorithms, and otherwise cleans and balances the SAM data. The preprocessor first builds on data to estimate total governmental revenues and expenditures for the model&#039;s base year and then uses available data on the breakdown of revenues and expenditures to calculate initial values of those streams consistent with the totals. Those who wish to understand the entire social accounting system, both initialization and forecast, should look to Hughes and Hossain (2003). More generally, the IFs [http://www.ifs.du.edu/assets/documents/preprocessorv1_0.pdf preprocessor&#039;s computational rules] assist in the initialization of all models within the IFs system and the connections among them, including reconciliation of physical systems such as energy and agriculture with financial ones.&lt;br /&gt;
&lt;br /&gt;
We make simplifying assumptions to move from limited data to initial values for total general government expenditures and revenues of all countries as a percentage of GDP. For OECD countries we have general government expenditure data (from the OECD), and we assume that the general government revenue share of GDP differs from the expenditures share by the same percentage as central government expenditure and revenue shares differ in WDI data; the implicit assumption is that local government expenditures and revenues are in balance For non-OECD countries we have only central government expenditures and revenues, and we estimate a size for local government revenues and expenditures that rises progressively from 2 percent for the lowest income countries to 14 percent for high-income countries—the latter being the contemporary average of OECD countries, and both the former and the rise being apparent in the data and discussion of North, Wallis, and Weingast (2009: 10).&lt;br /&gt;
&lt;br /&gt;
In the forecasting itself, there is similar attention to revenues and expenditures, but also attention to the cumulative imbalance between them and how that imbalance affects their dynamics over time. The model represents five revenue streams from taxes on household and firm income: household income taxes, household social security/welfare taxes, firm income taxes, firm social security/welfare taxes, and indirect taxes. In the absence of cross-country data on other revenue streams such as property taxes, the preprocessor allocates them in the base year to household taxes, a category for which data are especially weak. Total domestic government revenue is computed from the five streams. Foreign assistance augments domestic revenue in computing the fiscal balance with expenditures.&lt;br /&gt;
&lt;br /&gt;
[[Economics#Government_Expenditure|Government expenditures]] (GOVEXP) combine direct consumption expenditures (GOVCON) and transfer payments, especially to households (GOVHHTRN). Direct government consumption as a portion of GDP is computed from functions linking GDP per capita (PPP) to key elements of spending such as military, health, and education; total government consumption generally rises with GDP per capita. An additional optional term in the equation is a Wagner term (set to zero in the Base Case), after the discoverer of the long-term behavioral tendency for government consumption to rise as a share of GDP. The final division of government consumption into target destination categories, namely military, education, health, research and development, infrastructure (two subcategories) and an &amp;quot;other&amp;quot; or residual category, depends on a combination of functions and broader algorithmic and modeling elements specific to each spending category (including, for instance, demand for expenditures from the education and infrastructure models). The model normalizes across spending categories to assure that they equal total government consumption. As a general rule, transfer payments grow with GDP per capita more rapidly than does direct government consumption. And within the category of transfer payments, pension payments grow especially rapidly in many countries, particularly in more economically developed ones. Computation of government transfers involves integrating two different behavioral logics, a top-down one depending on general relationships to income and a bottom-up one. The bottom-up logic is especially important in the analysis of pensions, because it is responsive to the changing size of the elderly population.&lt;br /&gt;
&lt;br /&gt;
With completed computations of revenues and expenditures, it is possible to compute the [[Economics#Government_Balances_and_Dynamics|government fiscal balance]], an annual flow variable. That allows the update of cumulative government financial assets or debt and a calculation of their magnitude relative to GDP. IFs uses this cumulative total as a percentage of GDP in its equilibrating dynamics for annual government revenues and expenditures.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Broader Regime Capacity&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Forecasting of variables that relate to broader regime capacity in IFs has three elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); (3) an algorithmic linkage to internal conflict. A fourth potential element could be factors external to the country including global waves and neighborhood effects, but we introduce those only through scenario analysis.&lt;br /&gt;
&lt;br /&gt;
Corruption is one of the most powerful indicators of capacity (or more accurately, lack of capacity) as well as accountability. We rely in our analysis on the Transparency International index of corruption perceptions (CPI), which is actually a measure of transparency (higher values are more transparent or less corrupt). The basic formulation in IFs for corruption/transparency (below) contains four statistically significant drivers, which collectively account for nearly 80 percent of the cross-country variation in corruption in the most recent year of data. The first term, and the one identified with the most variation, involves a variable representing long-term development, namely GDP per capita (years of education plays that same role in forecasting formulations for some other governance variables, such as democracy).&lt;br /&gt;
&lt;br /&gt;
Interestingly, a second very powerful driving variable is the Gender Empowerment Measure (GEM), which, in spite of its high correlation with GDP per capita, makes its own contribution and suggests the power of inclusion in affecting capacity. In fact, still another driving variable is the extent of democracy, further suggesting the power that inclusion may have to increase accountability and transparency, reducing corruption. A less-powerful but still-significant variable is the dependence of the country on exports of energy—in a few years, and in the aftermath of the Arab Spring beginning in 2011, this term may drop out of cross-sectional analyses of change in governance capacity but will still probably remain very important for those countries with low levels of development and inclusion. (We find that the same drivers work well (an R-squared of 0.62) for the IFs economic freedom variable, based on the Fraser Institute/Economic Freedom Network measure.) A multiplier for scenario analysis is the only exogenous element added to the basic formulation.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVCORRUPT_{r,t}=(1.576+0.1133*GDPPCP_{r,t}+2.270*GEM_{t,r}+0.02779*DEMOCPOLITY_{r,t}-0.04566*(ENX_{r,t}*(\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{govcorruptm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared in 2010 = 0.75&lt;br /&gt;
&lt;br /&gt;
We compute an additive adjustment term (not shown in the equation) on top of the basic formulation in the base year to capture any difference between the value anticipated in the formulation and the value from data. In most of our formulations we use additive or multiplicative terms in this manner, and the adjustment term introduces the impact of other variables not in the statistically estimated equation (such as historical path dependencies and cultural differences). The additive adjustment term gradually converges to zero over time in our forecasts. The logic behind such convergence is twofold: first, many differences from initial anticipated values are the result of transient factors and even data errors; second, ongoing global processes tend to lead to a convergence of patterns across countries.&lt;br /&gt;
&lt;br /&gt;
There is every reason to believe that the presence of domestic conflict will reduce governmental capacity, including leading to lower levels of transparency (higher corruption). In fact, the inverse relationship between the IFs internal war variable (SFINTLWARALL) and transparency is strong. Even when added to the full equation above it remains quite strong (a T-score of -1.97). Because conflict tends to be quite variable over time, however, we undertook more analysis rather than simply adding conflict to the equation for corruption. Specifically, we experimented with different coefficients in analysis across the historical period (1960-2010). In doing so, we reinforced the result of the pure statistical analysis that a movement from 0 (no conflict) to 1 (conflict) appears to increase corruption (to lower the TI measure) by 0.6 points. We algorithmically overlaid this relationship on the basic equation above.&lt;br /&gt;
&lt;br /&gt;
There are times when the user will wish to introduce normatively controlled target values for corruption. One approach is use of the &amp;quot;brute force&amp;quot; multiplier on corruption (&#039;&#039;&#039;&#039;&#039;govcorruptm&#039;&#039;&#039; &#039;&#039;). A second approach involves the specification of target values relative to a function of the key drivers estimated cross-sectionally across countries. This second approach allows, for instance, the specification of a target level 1 or 2 standard errors (SE) above the level expected of a country given those drivers. The SE target parameter is &#039;&#039;&#039;&#039;&#039;govcorruptsetar&#039;&#039;&#039; &#039;&#039;and the &#039;&#039;&#039;&#039;&#039;govcorruptseyrtar&#039;&#039;&#039; &#039;&#039;carries the years to achieve the target. Relevant to the discussion below, there are similar control parameters for regulatory quality (&#039;&#039;&#039;&#039;&#039;govregqualsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;govreqqualseyrtar&#039;&#039;&#039; &#039;&#039;) and for effectiveness (&#039;&#039;&#039;&#039;&#039;goveffectsetar&#039;&#039;&#039; &#039;&#039;and &#039;&#039;&#039;&#039;&#039;goveffectseyrtar&#039;&#039;&#039; &#039;&#039;), but not for economic freedom.&lt;br /&gt;
&lt;br /&gt;
Looking beyond the corruption/transparency measure of Transparency International, IFs also forecasts a number of capacity-related variables from the World Bank&#039;s World Governance Indicators project (Kaufmann, Kraay, and Mastruzzi 2010) that we did not use to define the capacity dimension, but that are still of significant interest (used, for instance, in forward linkages to the building of infrastructure). These include the quality of government regulation and government effectiveness. The approaches are identical to those used for corruption and involve the same drivers. The R-squared values are again high (0.74 and 0.72, respectively).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GOVREGQUAL_{r,t}=(-1.018+0.726*ln(GDPPCP_{r,t})+0.2085*EDYRSAG15_{r,t}+2.5*\mathbf{govregqualm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Overview&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
Inclusion has many elements that reach beyond democratization or regime type and gender empowerment. For reasons including conceptual clarity, data availability and parsimony, we limit our forecasting to those two elements.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Regime Type&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
As with capacity, the forecasting of regime type in IFs has multiple elements: (1) a basic statistical formulation; (2) a recognition of country-specific differences (tied in part to path dependencies); and (3) algorithmic specification of a number of additional factors, including global waves and neighborhood effects.&lt;br /&gt;
&lt;br /&gt;
A look at the historical patterns since 1960 of democratization across global regions shows a substantial almost global increase in democracy levels in the late 1970s and 1980s. That suggests reasons that a multi-element and potentially algorithmic forecasting formulation can be useful. Most analyses of democratization place much emphasis on a developmental variable such as GDP per capita. Note, for instance, that the general upward movement of democracy across most developing regions could be forecast with a basic formulation tied to the traditionally-identified development drivers of democracy, including income and education increase. Again, however, this historical pattern, with a clear dip in the early years of the post-1960 period and an accelerated advance in the later decades is consistent with a global wave that a formulation tied only to quite steadily growing long-term developmental variables could not generate. Further, a formulation tied only to such drivers would be unlikely to generate initial conditions for 1960 or 2010 consistent with the actual history, because country and regional values in those years also reflect historical path dependencies.&lt;br /&gt;
&lt;br /&gt;
In building an initial, statistically-based formulation, we looked, as usual, at the power of two highly-correlated long-term development variables (notably GDP per capita and average education years attained by adults). The better broad developmental driving variable proved to be years of adults&#039; education. With additional exploration, however, we found a slight further advantage for the Gender Empowerment Measure, and so replaced the education variable with the GEM (which is, itself, strongly influenced by adults&#039; education). On top of that we found the size of the youth bulge (YTHBULGE) and extent of dependence on energy exports (ENX times the price ENPRI) as a share of GDP to be quite useful (see the discussions in these variables in Chapter 3 of Hughes et al. 2014).&lt;br /&gt;
&lt;br /&gt;
In the equation below, the basic IFs formulation, all terms are significant with T-scores above 2.0 in absolute terms. In earlier work we also explored a linkage to the survival/self-expression dimension of the World Value Survey, but have found that other development variables statistically force it out of the relationship.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBase_{r,t}=(13.4+11.4*GEM_{r,t}-9.73*YTHBULGE_{r,t}-0.232*(ENX_{r,t}*\frac{ENPRI_{r,t}}{GDP_{r,t}}))*\mathbf{democm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

The initial conditions of democracy in countries carry a considerable amount of idiosyncratic, country-specific influence, much of which can be expected to erode over time. Therefore a revised base level is computed that converges over time from the base component with the empirical initial condition built in to the value expected purely on the base of the analytic formulation. The user can control the rate of convergence with a parameter that specifies the years over which convergence occurs (&#039;&#039;&#039;&#039;&#039;polconv&#039;&#039;&#039; &#039;&#039;) and, in fact, basically shut off convergence by sitting the years very high.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITYBaseRev_{r,t}=ConvergeOverTime(DEMOCPOLITYBase_{r,t},DEMOCEXP_{r,t},\mathbf{polconv})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The endogenous movement of this basic calculation can also be overridden by the users via the specification of a target value for democracy some number of standard errors (&#039;&#039;&#039;&#039;&#039;democpolitysetar&#039;&#039;&#039; &#039;&#039;) above or below the cross-sectional estimation of the formulation and the movement of the basic value to that target over a specified number of years (&#039;&#039;&#039;&#039;&#039;democpolityseyrtar&#039;&#039;&#039; &#039;&#039;). Such targeting of important variables is done in an [http://www.du.edu/ifs/help/understand/equations/specialized/setargeting.html algorithm described elsewhere].&lt;br /&gt;
&lt;br /&gt;
Additionally we built structures, largely algorithmic, that allow forecasting with waves of democratization influenced by the impetus provided by systemic leadership, computing the magnitude of the global wave effect for all countries (DemGlobalEffects). Those depend on the amplitude of waves (DEMOCWAVE) relative to their initial condition and on a multiplier (EffectMul) that translates the amplitude into effects on states in the system. Because democracy and democratic wave literature often suggests that the countries in the middle of the democracy range are most susceptible to movements in the level of democracy, the analytic function enhances the affect in the middle range and dampens it at the high and low ends.&lt;br /&gt;
&lt;br /&gt;
The democratic wave amplitude is a level that shifts over time (DemocWaveShift) with a normal maximum amplitude (&#039;&#039;&#039;&#039;&#039;democwvmax&#039;&#039;&#039; &#039;&#039;) and wave length (&#039;&#039;&#039;&#039;&#039;democwvlen&#039;&#039;&#039; &#039;&#039;), both specified exogenously, with the wave shift controlled by a endogenous parameter of wave direction that shifts with the wave length (DEMOCWVDIR). The normal wave amplitude can be affected also by impetus towards or away from democracy by a systemic leader (DemocImpLead), assumed to be the exogenously specified impetus from the United States (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) compared to the normal impetus level from the U.S. (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;) and the net impetus from other countries/forces (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCWAVE_t=DEMOCWAVE_{t-1}+DemocimpLead+\mathbf{democimpoth}+DemocWaveShift&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocimpLead=\frac{(\mathbf{democimpus}-\mathbf{democimpusn})*\mathbf{eldemocimp}}{\mathbf{democwvlen}}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DemocWaveShift=\frac{\mathbf{democwvmax}}{\mathbf{democwvlen}}*DEMOCWVDIR&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Our historical analysis suggests the waves could have magnitudes (trough to peak) of as much as 6 points on the 20-point Polity scale of combined democracy and autocracy, although we found in historical analysis that downward shifts tend to be only one-third as great as upward movements. We found that the swings appear greatest in the anocracies, and that countries with higher incomes appear unaffected by them. We have structured and then &amp;quot;tuned&amp;quot; the general IFs representation of such effects so that the representation appears generally consistent with behavior over our 1960–2010 period of historical analysis. Nonetheless, we have no basis for forecasting the impetus that the U.S. or other systemic leadership might provide in the future, and we therefore set parameters for forecasting so that the effect is neutralized unless model users decide to introduce such an impetus on a scenario basis. The parameter for the U.S. impetus (&#039;&#039;&#039;&#039;&#039;democimpus&#039;&#039;&#039; &#039;&#039;) is set equal to the parameter for &amp;quot;normal&amp;quot; impetus (&#039;&#039;&#039;&#039;&#039;democimpusn&#039;&#039;&#039; &#039;&#039;), and that for other sources of impetus (&#039;&#039;&#039;&#039;&#039;democimpoth&#039;&#039;&#039; &#039;&#039;) is set to 0.&lt;br /&gt;
&lt;br /&gt;
On top of the country-specific calculation and the global wave effect sits an (optional) regional or swing state effect calculation (SwingEffects), turned on by setting the swing states parameter (&#039;&#039;&#039;&#039;&#039;swseffects&#039;&#039;&#039; &#039;&#039;) to 1. The countries set as default neighborhood leaders are Brazil, Indonesia, Mexico, Nigeria, Pakistan, Russian Federation, South Africa, Turkey, and the Ukraine.&lt;br /&gt;
&lt;br /&gt;
The swing effects term has three components. The first is a world effect, whereby the democracy level in any given state (the &amp;quot;swingee&amp;quot;) is affected by the world average level, with a parameter of impact (&#039;&#039;&#039;&#039;&#039;swingstdem&#039;&#039;&#039; &#039;&#039;) and a time adjustment (&#039;&#039;&#039;&#039;&#039;timeadj&#039;&#039;&#039; &#039;&#039;). The second is a regionally powerful state factor, the regional &amp;quot;swinger&amp;quot; effect, with similar parameters. The third is a swing effect based on the average level of democracy in the region (RgDemoc). The size of the swing effects is further constrained algorithmically by an external parameter (&#039;&#039;&#039;&#039;&#039;swseffmax&#039;&#039;&#039; &#039;&#039;), not shown in the equation below.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=timeadj*\mathbf{swingstsdem}_{r=Swinger,p=1}*(WDemoc_{t-1}-DEMOCPOLITY_{r=Swingee,t-1}+timadj*\mathbf{swingstdem_{r=Swinger,p=2}}*(DEMOCPOLITY_{r=Swinger,t-1}-DEMOCPOLITY_{r=Swingee,t-1})+timadj*\mathbf{swingstdem_{r=Swinger,p=3}}*(RgDemoc-DEMOCPOLITY_{r=Swingee,t-1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where timeadj=.2&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WDemoc_{t-1}=\frac{\sum^RDEMOCPOLITY_{r,t-1}}{R}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
else&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SwingEffects_{r,t}=0&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
David Epstein of Columbia University did extensive estimation of the parameters (the adjustment parameter on each term is 0.2). Unfortunately, the levels of significance were inconsistent across swing states and regions. Moreover, the term with the largest impact is the global term, already represented somewhat redundantly in the democracy wave effects. Hence, these swing effects are normally turned off (the sweffects parameter is 0 in the Base Case scenario) and are available for optional use.&lt;br /&gt;
&lt;br /&gt;
Further, we anticipated and explored for an impact of internal war on democratization, as discussed in some of the literature. Although there is a cross-sectional relationship, it is weak. Further, when the variable is added to a formulation with a long-term driver such as GEM, it actually reverses sign (more war is associated with greater democracy) and the significance drops further. One of the analytical difficulties is that a number of countries, like India and Israel, are both democratic and prone to internal conflict. Internal conflict conceptualization and measurement probably need refinement to take into consideration the actual threat level that internal war poses to regimes. We have explored the relationship using the PITF data on conflict magnitude rather than simply event occurrence and have found similar difficulties. Given our analysis, we have not built a relationship from intrastate conflict into our forecasting of democracy.&lt;br /&gt;
&lt;br /&gt;
Thus the final equation for democracy adds the global wave effects and the swing effects (both turned off in the base case) to the revised basic calculation of it.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;DEMOCPOLITY_{r,t}=DEMOCPOLITYBaseRev_{r,t}+SwingEffects_{r,t}+DemGlobalEffects_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
IFs has the capability of doing an historical simulation between 1960 and 2010 so that we can compare with data. We undertook such an analysis using the basic democratization formulation and wave-based modifications to it described above. Although we introduced an historical wave exogenously, no other interventions were made to affect the course of the forecasts for level of democracy. The R-squared in a cross-sectional analysis comparing the IFs regional forecast for 2010 against Polity data was 0.69 and the value across the entire time period was 0.78. That provides a false sense of the accuracy of our historical forecasts, however. At the country level the R-squared in 2010 was only 0.09 and the value over the entire 50-year period was 0.37. IFs expected higher values than proved to be the case for countries including Qatar, Singapore, Cuba, Kuwait, and Belarus. IFs expected lower values than Polity data show for countries including Nigeria, Ethiopia, Bangladesh and Moldova.&lt;br /&gt;
&lt;br /&gt;
Most significantly, IFs failed to anticipate the large rise in democracy in Africa in the 1990s. More generally, however strong our basic formulations for forecasting democracy may become, they are unlikely to foresee the timing of transitions toward or away from democracy. One approach to helping with that is to try to assess the pressures or unmet demand for democracy. As a small step in that direction, and using the concept of democratic deficit that Chapter 2 introduced, the model also computes an expected democracy variable (DEMOCEXP) directly from the equation above without exogenous multiplier or convergence to the function. This is useful for those who wish to see the magnitude of a country&#039;s democratic deficit or surplus by comparing DEMOC with DEMOCEXP. In fact, in advance of the Arab spring of 2011, IFs analysis (Cilliers, Hughes, and Moyer 2011) had identified the Middle East and North Africa as having exceptionally large democratic deficits.&lt;br /&gt;
&lt;br /&gt;
Although we use the Polity democracy measure as our central indicator of regime type (including its use in the more general measure of governance inclusiveness) IFs also calculates in a simpler fashion a FREEDOM measure (combining the Freedom House political rights and civil liberties scales into one scale running from least to most free). Specifically, the drivers are GDP per capita and adult educational attainment, our two standard long-term development drivers. Interestingly, the R-squared between the democracy and freedom measures in 2010 (using data from both projects) is 0.686 and that in 2060 (using forecasts of IFs for both measures) is a nearly identical 0.689. This suggests that the long-term driver variables in our formulations are doing a quite good job of representing the similarities and differences in the two measures.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;FREEDOM_{r,t}=(6.3718+1.6659*ln(GDPPCP_{r,t})+0.1293*EDYRSAG15_{r,t})*\mathbf{freedomm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;

&lt;br /&gt;
:R-squared=0.402&lt;br /&gt;
&lt;br /&gt;
Although IFs uses the Polity measure of democracy (DEMOCPOLITY) as its main measure of more formal, electoral inclusion, Freedom House&#039;s freedom measure (FREEDOM) is a logical alternative and the second of that measure&#039;s sub-dimensions, civil liberties, is a more inclusive measure. We therefore compute it also, using again GDP per capita and educational years (of all adults, not just females) as drivers. And there is a brute force multiplier for it also (&#039;&#039;&#039;&#039;&#039;freedomm&#039;&#039;&#039; &#039;&#039;). There is no SE targeting mechanism in place for the freedom variable.&lt;br /&gt;
&lt;br /&gt;
=== &amp;lt;span style=&amp;quot;font-size:medium;&amp;quot;&amp;gt;Equations: Gender Empowerment&amp;lt;/span&amp;gt; ===&lt;br /&gt;
&lt;br /&gt;
It is not surprising that a measure of women&#039;s inclusion, such as the Gender Empowerment Measure (GEM) of the UNDP, should correlate highly with GDP per capita or years of formal education of adult women. As we have seen, income and education are closely correlated and one or the other is almost invariably a key driver in our forecasts of change in governance. It is perhaps more surprising, in the formulation below, that together they both make statistically significant contributions to GEM. The relationship between GDP per capita and the GEM has shifted over time—the advance of global education, even in countries with low levels of income, helps explain that shift and almost certainly helps account for the independent contribution of education to higher levels of female empowerment. Interestingly, women&#039;s education does not differ in its statistical contribution from that of men; we nonetheless use that of women in our formulation.&lt;br /&gt;
&lt;br /&gt;
One might expect a strong relationship between total fertility rate and GEM as women who bear fewer children rise in other ways in society. There is, in fact, a strong correlation. Interestingly, however, a stronger one inversely relates the size of the youth bulge to the GEM. The IFs formulation is:&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GEM_{r,t}=(0.4429+0.003401*GDPPCP_{r,t}+0.0271*EDYRSAG15_{r,g=f,t}-0.506*YTHBULGE_{r,t})*\mathbf{gemm}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;where&#039;&#039;&lt;br /&gt;
&lt;br /&gt;
:GEM=UNDP Gender Empowerment Measure&lt;br /&gt;
&lt;br /&gt;
:GDPPCP=GDP per capita at purchasing power parity in thousand dollars&lt;br /&gt;
&lt;br /&gt;
:EDYRSAG15=average years of education for females age 15 or older&lt;br /&gt;
&lt;br /&gt;
:YTHBULGE=youth bulge, the population aged 15–29 as a portion of the entire adult population&lt;br /&gt;
&lt;br /&gt;
:&#039;&#039;&#039;gemm&#039;&#039;&#039;=an exogenous multiplier for scenario analysis&lt;br /&gt;
&lt;br /&gt;
:R-squared in 2010=0.66&lt;br /&gt;
&lt;br /&gt;
We experimented with a variation on the above formulation in which GDP per capita enters in a logged term, and found nearly as high an R-squared (0.64). However, a problem in longer-term forecasting with such a variation is that the saturation of the log of GDP per capita nearly stops growth in GEM for more developed countries, often well below parity for women.&lt;br /&gt;
&lt;br /&gt;
A user can control the progression of gender empowerment with a simple multiplier (&#039;&#039;&#039;&#039;&#039;gemm&#039;&#039;&#039; &#039;&#039;) or via setting a target value for it movement to some number of standard errors above or below a cross-sectionally estimated function (&#039;&#039;&#039;&#039;&#039;gemsetar&#039;&#039;&#039; &#039;&#039;) across a set number of years (&#039;&#039;&#039;&#039;&#039;gemseyrtar&#039;&#039;&#039; &#039;&#039;).&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Governance Indices&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
[[Governance#Governance|IFs represents three dimensions of governance (security, capacity, and inclusion) and uses two sub-dimensions for each]]. Just as the dimensions themselves show considerable conceptual independence, the sub-dimensions tend not to be highly correlated.&lt;br /&gt;
&lt;br /&gt;
Thus there is value in creating an index for each of the three governance dimensions that integrates the two variables representing them as well as an overall index. We have taken the typical basic approach to index construction when there is no clear external referent against which to judge the validity of the resultant index; that is, we have scaled each variable from 0 to 1 and averaged the two variables that make up each dimension. The resultant indices, GOVINDSECUR, GOVINDCAPAC, and GOVINDINCLUS, each have a global average value near 0.5, but the distribution of countries across the component measures varies; for instance, because the intrastate conflict variable of the security index exhibits a power-law distribution, the global average of the security measure is slightly higher than that of the other two indices. The security index uses 1.0 minus the average of the probability of intrastate war and the IFs performance risk index—the relative infrequency of intrastate war causes many states to cluster near 1.0 in the former formulation.&lt;br /&gt;
&lt;br /&gt;
In computing the index for governance capacity, we do not attribute increased capacity to countries when the revenue to GDP ratio rises above 0.45. Migdal (1988: 281) and Joshi (2011) suggest that the appropriate upper limit is 0.30, but their focus is on central government; our own analysis suggests that local government can on average for high-income countries add another 0.15 (15 percent of GDP) to that ratio.&lt;br /&gt;
&lt;br /&gt;
Finally, we compute an overall governance index (GOVINDTOTAL) as the simple average across the three dimensions. Just as the rankings of countries on the three dimensional indices provide some face or subjective validity to the indices, the rankings on the combined index likely correspond to the general perceptions that most analysts have.&lt;br /&gt;
&lt;br /&gt;
= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Performance Risk Analysis Form&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
IFs includes a Performance Risk Index (GOVRISK) and an associated display to facilitate Performance and Risk Analysis, for instance by changing the weight of variables in the index. The design is intended primarily for analysis of single countries, but the form allows also consideration of country groups. It also facilitates comparison of alternative scenarios, mainly to display single country characteristics, but with the ability to switch to groups, compare different scenarios, different countries or groups.&lt;br /&gt;
&lt;br /&gt;
The overall risk form and index build on nine categories of variables:&lt;br /&gt;
&lt;br /&gt;
:The first three categories correspond to the three dimensions of governance in IFs but do not use precisely the same sub-dimensional variables (in part because the performance risk index is itself a sub-dimension of security and that would create a circularity, but partly also because the risk index is meant to be a dynamic assessment vehicle that allows users to tailor the analysis to their own understanding of what constitutes risk. The three governance dimensions and variables used in the index are: security (instability and internal war); capacity (corruption and effectiveness); and inclusion (democracy, freedom, and the gender empowerment measure).&lt;br /&gt;
&lt;br /&gt;
:The next three categories in the index are associated with drivers that many analysts have associated with country risk. The categories and associated variables are: population (youth bulge, elderly bulge [with a 0-weighting for the developing country oriented analysis of interest to most form users], and urbanization rate); environment (water use as a portion of renewable supplies and climate change); international (power transition).&lt;br /&gt;
&lt;br /&gt;
:The final three categories in the index represent specific arenas of government and societal performance. Again with associated variables they are: the economy (poverty, inequality, resource export dependence, and per capita GDP growth rate); health (infant mortality, life expectancy, malnutrition and HIV prevalence); and education (primary net enrollment and years of formal education of adults).&lt;br /&gt;
&lt;br /&gt;
Information about each country across variables is organized into two clusters of columns. The first cluster provides information about values and ranks:&lt;br /&gt;
&lt;br /&gt;
:The Value column is the actual IFs forecast for each specific variable (for instance, the life expectancy for Angola in 2010 reflects data and is near 50.&lt;br /&gt;
&lt;br /&gt;
:The Min Level and Max Level columns indicate the overall range over which each variable varies across counties and time. These levels are constant across years and countries. They are used in computing the Scaled Levels.&lt;br /&gt;
&lt;br /&gt;
:The Scaled Level column uses the minimum and maximum levels to scale values for each country from 0 to 1. The scaling takes into account the valence of each variable (that is, infant mortality is bad and life expectancy is good). The Summary Measure in the last row of this column is a weighted average of the scaled levels on each variable; this computation is saved as the GOVRISK variable in our forecast files for each country and each year&lt;br /&gt;
&lt;br /&gt;
:The Global Rank column indicates how each country ranks among all countries on each variable. The Summary Measure in the last row at the bottom of the column uses a weighted average of the ranks for each variable to compute the ordinal position of the country when sorting across all countries. Lower Ranks indicate higher risk levels (or worst performance). Clicking on any cell in this column provides a pop-up option for showing the rank of all countries on specific variables or the Summary Measure.&lt;br /&gt;
&lt;br /&gt;
:The Weighting column determines how the variables are combined in computing the summary Scaled Levels and Global Ranks of a country. Clicking on any cell in that column allows the user to change the weight for the associated variable.&lt;br /&gt;
&lt;br /&gt;
[[File:Govchart04.png|frame|center|Performance Risk Index]]&lt;br /&gt;
&lt;br /&gt;
:The color for each variable in the Value column indicates the position of the value relative to the alert and goal levels. Values between the alert and goal levels are yellow, values on undesirable side of the alert level (depending on the valence of the variable) are red, and values on the desirable side of the goal level are green. For the Summary Measure the color coding is a bit different: .red indicates the 40 countries performing least well in the aggregate (numbers 1 through 40 in the Global Rank column), green shows the 40 countries doing best; yellow indicates all other countries.&lt;br /&gt;
&lt;br /&gt;
The second cluster of columns provides evaluation information. Evaluation can be either absolute or relative to income (actually GDP per capita), as determined by the menu option that toggles between those two forms (the column cluster heading changes also with the toggle value). The default approach is absolute evaluation, setting up comparison of countries and evaluation of their performance independently of their development level.&lt;br /&gt;
&lt;br /&gt;
The relative or income-adjusted evaluation approach takes into account the GDP per capita of the country and has a &amp;quot;benchmarking&amp;quot; character. That is, evaluation of countries takes into account the GDP per capita at PPP of countries, expecting different performance at difference levels. The expectations upon which relative evaluation occurs are related to cross-sectionally estimated relationships of the Values for each variable across all countries. For instance, the cross-sectional relationship for Inequality using the Gini index (on the Y-axis) as a function of GDP per capita at PPP (on the X-axis) is the following:[[File:Govchart10.gif|frame|right|Inequality using the Gini index as a function of GDP per capita at PPP]]&lt;br /&gt;
&lt;br /&gt;
Higher values indicate poorer performance or more risk and Colombia is shown on this figure as having a considerably higher than expected level of inequality. We would expect Colombia to be evaluated poorly on this variable both in absolute terms and relative to its income level.&lt;br /&gt;
&lt;br /&gt;
The columns in the Evaluation cluster are:&lt;br /&gt;
&lt;br /&gt;
:Goal and Alert Levels will change depending on the evaluation method. When using absolute evaluation, the level values will not vary across countries (we have set absolute Goal and Alert Levels exogenously based on our own analysis across countries). When using income-adjusted or relative evaluation, the values will be recomputed based on the GDP per capita level of a specific country in a given year. Specifically, in income-adjusted evaluation the Goal Levels are generally set at the value of the function for the GDP per capita of the country in the year being analyzed. The Alert Levels are generally 1 or 2 standard errors below or above the value of the function;&amp;lt;sup&amp;gt;[[http://www.du.edu/ifs/help/understand/governance/performance.html#footnote 1]]&amp;lt;/sup&amp;gt; below or above depends on whether higher or lower values indicate better performance.&lt;br /&gt;
&lt;br /&gt;
:The third evaluation column will show the Standard Deviation of Values for all countries around the global mean in the case of Absolute Evaluation and will show the Standard Error of all countries around the function in the case of income-adjusted evaluation.&lt;br /&gt;
&lt;br /&gt;
Useful information can be obtained beyond that apparent in the table by clicking on particular cells:&lt;br /&gt;
&lt;br /&gt;
:Cells within the Value, Scaled Level, and Standard Deviation/Standard Error columns can be displayed across time by clicking on them and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:You can generate a rank-ordered list of countries based on a given variable by clicking on a cell in the Global Rank column and selecting the pop-up menu option.&lt;br /&gt;
&lt;br /&gt;
:Clicking on a cell in the Value column and selecting the option &amp;quot;Display All Years and All Countries Ranked&amp;quot; produces a table of all values for all countries across time with countries ranked left-to-right from riskier to less risky values in the selected year.&lt;br /&gt;
&lt;br /&gt;
:Clicking on any variable name provides a pop-up menu with useful information related to evaluation. The Cross-Sectional Relationship option on that pop-up shows the function for the variable and selected country&#039;s position relative to the function. The Provide Information option provides information on the Goal and Alert Levels for any specific variable; it also gives a set of information explaining the variable and bibliographic references when available. The Show Count option will display the number of countries in alert level, moderate risk or not at risk using absolute evaluation only.&lt;br /&gt;
&lt;br /&gt;
Additional menu options exist on the form:&amp;amp;nbsp;&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Scenarios holding down the Ctrl key allows selecting multiple scenarios. Once selected they can be displayed simultaneously, for instance by clicking on a cell in the Value column and selecting the pop-up option to Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:On the form called up by Select Multiple Country/Regions or Groups holding down the Ctrl key allows selecting multiple countries or groups; again these can be displayed, for instance, by clicking on a cell in the Value column and requesting Show Over Time.&lt;br /&gt;
&lt;br /&gt;
:Using Countries/Regions is the default menu option geographically, but it toggles with click to Using Groups. Groups are displayed with ranks that weight country members by population (the group aggregations of Values use varying weighting variables; for instance, the climate change variable uses GDP).&lt;br /&gt;
&lt;br /&gt;

[1] There is subjectivity in this. We mostly use 2 standard errors (11 times); next we use 1 SE (9 times: Elderly Bulge, Poverty Level, Inequality, Rate of per capita Growth, Infant Mortality, Life Expectancy, Malnutrition, Adult Education Years and Urbanization Rate); then use 0.5 twice: Democracy and Freedom,&#039; and finally we use 0.2 for GEM.&amp;amp;nbsp;&lt;br /&gt;

&lt;br /&gt;
Governance is rooted in a much broader socio-cultural context including the condition of individuals within society and the values and beliefs they hold. Much of that context is spread across the various modules of IFs. For instance, literacy and educational attainment are determined in the education model. Income levels and income distribution are in the economic model. Here we focus primarily on the aggregation of those into the summary HDI indicator and the expression of them in selected indicators of values and cultural orientations.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Human Development&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Human development measures invariable look to such variables as life expectancy, literacy or other indication of educational attainment, income, etc. These variables are computed in other IFs models, but provide a basis for socio-political analysis.&lt;br /&gt;
&lt;br /&gt;
Literacy is a variable fundamentally tied to educational attainment. In IFs it changes from the initial level for a country because of a multiplier (LITM).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LIT_r=\mathbf{LIT}_{r,t=1}*LITM_r&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The function upon which the literacy multiplier is based represents the cross-sectional relationship globally between the percentage of adults who have completed a primary education (EDPRIPER from the education model) and literacy rate (LIT). Rather than imposing the typical literacy rate from this function (and thereby being inconsistent with initial empirical values), the literacy multiplier is the ratio of typical literacy given future adult primary completion percentage to the normal literacy level at initial primary completion percentage.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LITM=\frac{AnalFunc(EDPRIPER)}{AnalFunc(\mathbf{EDPRIPER}_{t=1})}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
At one time the IFs system represented an aggregate view of life conditions within a society by using the Physical Quality of Life Index (PQLI) of the Overseas Development Council (ODC, 1977: 147#154). This measure averaged literacy, life expectancy, and infant mortality, first normalizing each indicator so that it ranges from zero to 100.&lt;br /&gt;
&lt;br /&gt;
The United Nations Development Program&#039;s human development index (HDI) has fully supplanted that early measure in the development literature. The HDI began as is a simple average of three sub-indices for life expectancy, education, and GDP per capita (using purchasing power parity).. The GDP per capita index is a logged form that runs from a minimum of 100 to a maximum of $40,000 per capita. The original measure in IFs differs slightly from the original HDI version, because it does not put educational enrollment rates into a broader educational index with literacy.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Although the HDI is a wonderful measure for looking at past and current life conditions, it has some limitations when looking at the longer-term future. Specifically, the fixed upper limits for life expectancy and GDP per capita are likely to be exceeded by many countries before the end of the 21st century. IFs therefore introduced a floating version of the HDI, in which the maximums for those two index components are calculated from the maximum performance of any state in the system in each forecast year.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDIFLOAT_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAXFLOAT-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCMAX)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The floating measure, in turn, has some limitations because it introduces relative attainment into the equation rather than absolute attainment. IFs therefore developed still a third version of the original HDI, one that allows the users to specify probable upper limits for life expectancy and GDPPC in the twenty-first century. Those enter into a fixed calculation of which the normal HDI could be considered a special case.&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI21stFIX_r=\frac{LifeExpInd_r+LitInd+GDPInd}{3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDILIFEMAX21=\mathbf{hdilifemaxf}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{HDILIFEMAX21-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LitInd=LIT_r/100&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LogGDPPCP21=Log(\mathbf{hdigdppcmax}*1000)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(GDPPCP21)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
In 2010 the Human Development Report Office of the UNDP changed its computation of HDI and the IFs model followed suit with a new version named HDINEW. That measure moved to a different aggregation of the components, one that uses a geometric mean of the component elements. It further changed the computation by creating a revised education index that is a geometric mean of two subcomponents, mean years of schooling of adults (EDYRSAG25) and expected years of schooling of school entrants (EDYRSSLE). It continues to use life expectancy (LIFEXP) and gross national income per capita at PPP, for which IFs substitutes GDP per capita at PPP (GDPPCP).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;HDI_r=(LifeExpInd)^{1/3}*(EdInd)^{1/3}*(GDPInd)^{1/3}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;LifeExpInd=\frac{LIFEEXP_r-LIFEXPMIN}{LIFEXPMAX-LIFEXPMIN}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EdInd=(EDYRSSLEIND)^{1/2}*(EDYRSAG25IND)^{1/2}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;GDPInd=\frac{Log(GDPPCP_r*1000)-Log(100)}{Log(40000)-Log(100)}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSSLEIND=EDYRSSLE/EDYRSSLEMAX&amp;lt;/math&amp;gt;&lt;br /&gt;
:&amp;lt;math&amp;gt;EDYRSAG25IND=EDYRSAG25/EDYRSAG25MAX&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
We further compute several global indicators including a world life expectancy (WLIFE) and a world literacy rate (WLIT).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIFE=\frac{\sum^RLIFEXP_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;WLIT=\frac{\sum^RLIT_r*POP_r}{WPOP}&amp;lt;/math&amp;gt;&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Roots of Culture: Beliefs and Values&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
IFs computes change in three cultural dimensions identified by the World Values Survey (Inglehart 1997). Those are dimensions of materialism/post-materialism (MATPOSTR), survival/self-expression (SURVSE), and traditional/secular-rational values (TRADSRAT). On each dimension the process for calculation is somewhat more complicated than for freedom or gender empowerment, however, because the dynamics for change in the cultural dimensions involves the aging of population cohorts. IFs uses the six population cohorts of the World Values Survey (1= 18-24; 2=25-34; 3=35-44; 4=45-54; 5=55-64; 6=65+). It calculates change in the value orientation of the youngest cohort (c=1) from change in GDP per capita at PPP (GDPPCP), but then maintains that value orientation for the cohort and all others as they age. Analysis of different functional forms led to use of an exponential form with GDP per capita for materialism/postmaterialism and to use of logarithmic forms for the two other cultural dimensions (both of which can take on negative values).&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;MATPOSTR_{r,c=1}=\mathbf{MATPOSTR}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShMP}_{r=cultural}+\mathbf{matpostradd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShMP_{r=cultural,t}}=F(\mathbf{MATPOSTR}_{r,c=1,t=1},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;SURVSE_{r,c=1}=\mathbf{SURVSE}_{r,c=1,t=1}*\frac{AnalFunc(GDPPCP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShSE}_{r=cultural,t}+\mathbf{survseadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShSE}_{r=culutral,t}=F(\mathbf{SURVSE_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TRADSRAT_{r,c=1}=\mathbf{TRADSRAT}_{r,c=1,t=1}*\frac{AnalFunc(GDPPP_r)}{AnalFunc(GDPPCP_{r,t=1})}+\mathbf{CultShTS_{r=cultural,t}}+\mathbf{tradsratadd}_{r,t}&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
where&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;\mathbf{CultShTS}_{r=cultural,t}=F(\mathbf{TRADSRAT_{r,c=1,t=1}},AnalFunc(GDPPCP_{r,t=1})&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
The user can influence values on each of the cultural dimensions via two parameters. The first is a cultural shift factor (e.g. CultSHMP) that affects all of the IFs countries/regions in a given cultural region as defined by the World Value Survey. Those factors have initial values assigned to them from empirical analysis of how the regions differ on the cultural dimensions (determined by the pre-processor of raw country data in IFs), but the user can change those further, as desired. The second parameter is an additive factor specific to individual IFs countries/regions (e.g. matpostradd). The default values for the additive factors are zero.&lt;br /&gt;
&lt;br /&gt;
Some users of IFs may not wish to assume that aging cohorts carry their value orientations forward in time, but rather want to compute the cultural orientation of cohorts directly from cross-sectional relationships. Those relationships have been calculated for each cohort to make such an approach possible. The parameter (wvsagesw) controls the dynamics associated with the value orientation of cohorts in the model. The standard value for it is 2, which results in the &amp;quot;aging&amp;quot; of value orientations. Any other value for wvsagesw (the WVS aging switch) will result in use of the cohort-specific functions with GDP per capita.&lt;br /&gt;
&lt;br /&gt;
Regardless of which approach to value-change dynamics is used, IFs calculates the value orientation for a total region/country as a population cohort-weighted average.&lt;br /&gt;
&lt;br /&gt;
Although we have explored the forward linkages of value change to other variables, including democracy, the IFs project has not given either the forecasting of value/culture change nor the impacts of it the attention they deserve. This is a great opportunity for creative thinking and modeling in the future.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

| style=&amp;quot;width: 93px;&amp;quot; | Limit&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the [[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate.&lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

&lt;br /&gt;
Three major integrated scenarios on health were developed by the Pardee Center for the health volume of the Patterns of Potential Human Progress series (Hughes et al., 2011). The World Integrated Scenario Sets folder contains the scenarios that were built for this volume, of which three are worth an extended discussion. The first is the Proximate Drivers Excluding Environment folder, which contains parameters to individually alter four of the major risk factors for several causes of mortality. These are Body Mass Index which is a risk factor for cardiovascular disease; under nutrition, which is a risk factor for communicable diseases; smoking which is a risk factor for respiratory disease; and large increases in the number of cars per person coupled with poor pedestrian safety, which is a major risk factor for accidental death. This scenario also includes increased to improved water sources and piped sanitation taken from the infrastructure module, and parameters to reduce environmental exposure to poor air quality. This scenario reduces these risk factors to their theoretical minima, to simulate aggressive efforts to reduce, high BMI, the obesity rate, childhood malnutrition, smoking, and traffic mortality. Malnutrition is set to 0.01, smoking and obesity multipliers are set to 0, BMI multiplier to 0.8, vehicle fleets to 0.5, and traffic mortality to 0. &lt;br /&gt;
&lt;br /&gt;
Another important pair of prepackaged scenarios contains the optimistic Luck and Enlightenment scenario, and a scenario that considers what happens when Things Go Wrong. The Luck and Enlightenment scenario includes improvements to HIV/AIDS, sanitation access, improved air quality, and reduced smoking rates which help lower the burden of NCDs. It also features changes to the burden of communicable disease designed to increase the levels of these. A variation to Luck and Enlightenment has add-ins that also increase foreign aid donations and agricultural yields, effectively modeling a situation in which increased global cooperation supports these efforts. Things Go Wrong models a world in which air quality worsens, smoking and obesity rates increase and there is little international cooperation on addressing these challenges.&lt;br /&gt;

HIV and AIDS have attracted significant interest among policy makers because of the tremendous toll that these diseases have on populations in both human and economic terms. Because of this interest, it is worth discussing the HIV/AIDS submodule separately from the rest of the health module. That submodule represents both the extent of HIV prevalence in a population (a stock variable) and the annual deaths from AIDS (a flow variable driven in substantial part by the prevalence rate, but also responsive to technological advance in the fight against AIDS). A number of key variables are available to represent the burden of HIV and AIDS within a country. &lt;br /&gt;
&lt;br /&gt;
Three variables are key to understanding the progression of infection within a country. &#039;&#039;&#039;HIVCASES&#039;&#039;&#039; provides the total number of HIV cases, &#039;&#039;&#039;HIVRATE&#039;&#039;&#039; represents a flow variable showing the rate at which people are being infected with HIV, and &#039;&#039;&#039;HIVTECCNTL&#039;&#039;&#039; indicates the progress being made in reducing the rate of infection within a country. &lt;br /&gt;
&lt;br /&gt;
Three other variables assess mortality due to HIV and AIDs within a country. Similar to HIV, the variables &#039;&#039;&#039;AIDSDTHS&#039;&#039;&#039; and &#039;&#039;&#039;AIDSDRATE&#039;&#039;&#039; indicate the number of AIDs deaths and the rate of mortality from AIDs respectively, while &#039;&#039;&#039;AIDSDTHSCM&#039;&#039;&#039; represents the cumulative number of deaths due to the disease.&lt;br /&gt;

&lt;br /&gt;
Modifying the infection rate with &#039;&#039;&#039;hivm&#039;&#039;&#039; is probably the easiest way to adjust the burden of HIV infection within a country. Like &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, &#039;&#039;&#039;hivm&#039;&#039;&#039; is a multiplicative parameter. In other words, increasing the value of the parameter in scenario analysis from 1 to 1.2 represents a 20% increase in the rate of infection relative to the base case. &#039;&#039;&#039;Hivtadvr&#039;&#039;&#039; allows users to change the prevalence of HIV, once the epidemic has peaked, by a certain percent annually to model different assumptions about the rate at which control technologies will improve, reducing the prevalence of the disease over time. Unlike the mortality multiplier, which takes effect once the model has calculated the base Variable Name Description HIVCASES Number of HIV cases HIVRATE HIV infection rate HIVTECCNTL Rate of technical control of infection, cumulative reduction in infection rate AIDSDTHS Number of AIDS deaths AIDSDRATE Death rate from AIDS AIDSDTHSCM Cumulative Number of AIDS deaths since first year of model 22 case, this parameter will affect the actual calculations the model makes while running. This parameter functions as additive factor to a growth rate within IFs. In other words, a 0.01 increase in the parameter represents a 0.01 increase in the growth rate for the technical advance rate in HIV infection control (&#039;&#039;&#039;hivtadvr&#039;&#039;&#039;). &lt;br /&gt;
&lt;br /&gt;
The HIV submodule is designed to allow users to affect the course of the epidemic across countries and across time. The multiplier &#039;&#039;&#039;hivmdcm&#039;&#039;&#039; is a multiplicative parameter that affects the maximum infection rate in middleincome developing countries. Another way to alter the course of the epidemic is by manipulating the coefficient on &#039;&#039;&#039;hivpeakr&#039;&#039;&#039;, which is an additive parameter that will increase the peak rate of infection over the course of the epidemic. Thus a 0.01 increase in the value of the coefficient represents a 0.01 increase in the peak infection rate. An associated parameter, &#039;&#039;&#039;hivpeakyr&#039;&#039;&#039; sets the date at which the epidemic will peak before the infection rate begins to decline. Changing this parameter in the Scenario Analysis page will allow users to set any year between 2010 and 2100 as the year of peak infection rate depending on their assumptions regarding the technical rate of advance in controlling the disease. Finally, the parameter hivincr controls the increased rate in infection prior to 2000, when our knowledge of the epidemic was much less complete and control efforts were far less effective.&lt;br /&gt;

&lt;br /&gt;
Just as there are a variety of parameters available to control the prevalence of HIV within a population, there are also a number of parameters that allow users to control the lethality of the epidemic. The first of these parameters allow user to change the death rate as a percentage of the infection rate via the parameter &#039;&#039;&#039;aidsdratem&#039;&#039;&#039;. This parameter directly alters the lethality of the disease; it serves as a proxy for the presence or absence of control measures within a country since the availability of anti-retroviral medications will affect the rate at which people who are HIV positive die from AIDs. Of course, new research strongly suggests that ART therapies may also significantly reduce the HIV infection rate as well, but because these are not yet linked in the model, users should be aware that a more realistic use of this parameter would alter not only the AIDs mortality rate, but the infection rate as well. The other parameter available to users to control mortality from AIDs is &#039;&#039;&#039;aidsdrtadvr&#039;&#039;&#039;, a parameter which changes the technical annual advance rate in control. This parameter simulates the annual advance in technologies to control AIDs mortality, altering the lethality of the disease.&lt;br /&gt;

The first, under the heading Hivaids in the Technological Advance section of the Framing Scenarios folder, models two scenarios around technological advance to control the epidemic. One models rapid technical advances to control HIV infection, while the other presents a scenario in which technological progress slows, slowing the resulting decline in infections. &lt;br /&gt;
&lt;br /&gt;
A second set of prepackaged scenarios are available to affect HIV/AIDS are focused on altering the course of the epidemic in key countries, rather than at a global level. They are called: Intermediate HIV/AIDS, Intermediate for New School Paper, Severe HIV Aids and Total Failure to Control HIV AIDs and are located in the Surprises and Wildcards folder, under the heading AIDs. These scenarios modify the course of the AIDS epidemic in Russia, China, India, and the world at large. Each one affects parameters controlling the infection rate at the peak year of the epidemic, the peak infection rate, the initial rate of infection, the rate of advance in the infection, and the elasticity of multifactor productivity to life expectancy. They give a good example of how to modify combinations of parameters in specific countries to create different trajectories for the epidemic.&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the [[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate.&lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

&lt;br /&gt;
Three major integrated scenarios on health were developed by the Pardee Center for the health volume of the Patterns of Potential Human Progress series (Hughes et al., 2011). The World Integrated Scenario Sets folder contains the scenarios that were built for this volume, of which three are worth an extended discussion. The first is the Proximate Drivers Excluding Environment folder, which contains parameters to individually alter four of the major risk factors for several causes of mortality. These are Body Mass Index which is a risk factor for cardiovascular disease; under nutrition, which is a risk factor for communicable diseases; smoking which is a risk factor for respiratory disease; and large increases in the number of cars per person coupled with poor pedestrian safety, which is a major risk factor for accidental death. This scenario also includes increased to improved water sources and piped sanitation taken from the infrastructure module, and parameters to reduce environmental exposure to poor air quality. This scenario reduces these risk factors to their theoretical minima, to simulate aggressive efforts to reduce, high BMI, the obesity rate, childhood malnutrition, smoking, and traffic mortality. Malnutrition is set to 0.01, smoking and obesity multipliers are set to 0, BMI multiplier to 0.8, vehicle fleets to 0.5, and traffic mortality to 0. &lt;br /&gt;
&lt;br /&gt;
Another important pair of prepackaged scenarios contains the optimistic Luck and Enlightenment scenario, and a scenario that considers what happens when Things Go Wrong. The Luck and Enlightenment scenario includes improvements to HIV/AIDS, sanitation access, improved air quality, and reduced smoking rates which help lower the burden of NCDs. It also features changes to the burden of communicable disease designed to increase the levels of these. A variation to Luck and Enlightenment has add-ins that also increase foreign aid donations and agricultural yields, effectively modeling a situation in which increased global cooperation supports these efforts. Things Go Wrong models a world in which air quality worsens, smoking and obesity rates increase and there is little international cooperation on addressing these challenges.&lt;br /&gt;

HIV and AIDS have attracted significant interest among policy makers because of the tremendous toll that these diseases have on populations in both human and economic terms. Because of this interest, it is worth discussing the HIV/AIDS submodule separately from the rest of the health module. That submodule represents both the extent of HIV prevalence in a population (a stock variable) and the annual deaths from AIDS (a flow variable driven in substantial part by the prevalence rate, but also responsive to technological advance in the fight against AIDS). A number of key variables are available to represent the burden of HIV and AIDS within a country. &lt;br /&gt;
&lt;br /&gt;
Three variables are key to understanding the progression of infection within a country. &#039;&#039;&#039;HIVCASES&#039;&#039;&#039; provides the total number of HIV cases, &#039;&#039;&#039;HIVRATE&#039;&#039;&#039; represents a flow variable showing the rate at which people are being infected with HIV, and &#039;&#039;&#039;HIVTECCNTL&#039;&#039;&#039; indicates the progress being made in reducing the rate of infection within a country. &lt;br /&gt;
&lt;br /&gt;
Three other variables assess mortality due to HIV and AIDs within a country. Similar to HIV, the variables &#039;&#039;&#039;AIDSDTHS&#039;&#039;&#039; and &#039;&#039;&#039;AIDSDRATE&#039;&#039;&#039; indicate the number of AIDs deaths and the rate of mortality from AIDs respectively, while &#039;&#039;&#039;AIDSDTHSCM&#039;&#039;&#039; represents the cumulative number of deaths due to the disease.&lt;br /&gt;

&lt;br /&gt;
Modifying the infection rate with &#039;&#039;&#039;hivm&#039;&#039;&#039; is probably the easiest way to adjust the burden of HIV infection within a country. Like &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, &#039;&#039;&#039;hivm&#039;&#039;&#039; is a multiplicative parameter. In other words, increasing the value of the parameter in scenario analysis from 1 to 1.2 represents a 20% increase in the rate of infection relative to the base case. &#039;&#039;&#039;Hivtadvr&#039;&#039;&#039; allows users to change the prevalence of HIV, once the epidemic has peaked, by a certain percent annually to model different assumptions about the rate at which control technologies will improve, reducing the prevalence of the disease over time. Unlike the mortality multiplier, which takes effect once the model has calculated the base Variable Name Description HIVCASES Number of HIV cases HIVRATE HIV infection rate HIVTECCNTL Rate of technical control of infection, cumulative reduction in infection rate AIDSDTHS Number of AIDS deaths AIDSDRATE Death rate from AIDS AIDSDTHSCM Cumulative Number of AIDS deaths since first year of model 22 case, this parameter will affect the actual calculations the model makes while running. This parameter functions as additive factor to a growth rate within IFs. In other words, a 0.01 increase in the parameter represents a 0.01 increase in the growth rate for the technical advance rate in HIV infection control (&#039;&#039;&#039;hivtadvr&#039;&#039;&#039;). &lt;br /&gt;
&lt;br /&gt;
The HIV submodule is designed to allow users to affect the course of the epidemic across countries and across time. The multiplier &#039;&#039;&#039;hivmdcm&#039;&#039;&#039; is a multiplicative parameter that affects the maximum infection rate in middleincome developing countries. Another way to alter the course of the epidemic is by manipulating the coefficient on &#039;&#039;&#039;hivpeakr&#039;&#039;&#039;, which is an additive parameter that will increase the peak rate of infection over the course of the epidemic. Thus a 0.01 increase in the value of the coefficient represents a 0.01 increase in the peak infection rate. An associated parameter, &#039;&#039;&#039;hivpeakyr&#039;&#039;&#039; sets the date at which the epidemic will peak before the infection rate begins to decline. Changing this parameter in the Scenario Analysis page will allow users to set any year between 2010 and 2100 as the year of peak infection rate depending on their assumptions regarding the technical rate of advance in controlling the disease. Finally, the parameter hivincr controls the increased rate in infection prior to 2000, when our knowledge of the epidemic was much less complete and control efforts were far less effective.&lt;br /&gt;

&lt;br /&gt;
Just as there are a variety of parameters available to control the prevalence of HIV within a population, there are also a number of parameters that allow users to control the lethality of the epidemic. The first of these parameters allow user to change the death rate as a percentage of the infection rate via the parameter &#039;&#039;&#039;aidsdratem&#039;&#039;&#039;. This parameter directly alters the lethality of the disease; it serves as a proxy for the presence or absence of control measures within a country since the availability of anti-retroviral medications will affect the rate at which people who are HIV positive die from AIDs. Of course, new research strongly suggests that ART therapies may also significantly reduce the HIV infection rate as well, but because these are not yet linked in the model, users should be aware that a more realistic use of this parameter would alter not only the AIDs mortality rate, but the infection rate as well. The other parameter available to users to control mortality from AIDs is &#039;&#039;&#039;aidsdrtadvr&#039;&#039;&#039;, a parameter which changes the technical annual advance rate in control. This parameter simulates the annual advance in technologies to control AIDs mortality, altering the lethality of the disease.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;br /&gt;
Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the [[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate.&lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

&lt;br /&gt;
Three major integrated scenarios on health were developed by the Pardee Center for the health volume of the Patterns of Potential Human Progress series (Hughes et al., 2011). The World Integrated Scenario Sets folder contains the scenarios that were built for this volume, of which three are worth an extended discussion. The first is the Proximate Drivers Excluding Environment folder, which contains parameters to individually alter four of the major risk factors for several causes of mortality. These are Body Mass Index which is a risk factor for cardiovascular disease; under nutrition, which is a risk factor for communicable diseases; smoking which is a risk factor for respiratory disease; and large increases in the number of cars per person coupled with poor pedestrian safety, which is a major risk factor for accidental death. This scenario also includes increased to improved water sources and piped sanitation taken from the infrastructure module, and parameters to reduce environmental exposure to poor air quality. This scenario reduces these risk factors to their theoretical minima, to simulate aggressive efforts to reduce, high BMI, the obesity rate, childhood malnutrition, smoking, and traffic mortality. Malnutrition is set to 0.01, smoking and obesity multipliers are set to 0, BMI multiplier to 0.8, vehicle fleets to 0.5, and traffic mortality to 0. &lt;br /&gt;
&lt;br /&gt;
Another important pair of prepackaged scenarios contains the optimistic Luck and Enlightenment scenario, and a scenario that considers what happens when Things Go Wrong. The Luck and Enlightenment scenario includes improvements to HIV/AIDS, sanitation access, improved air quality, and reduced smoking rates which help lower the burden of NCDs. It also features changes to the burden of communicable disease designed to increase the levels of these. A variation to Luck and Enlightenment has add-ins that also increase foreign aid donations and agricultural yields, effectively modeling a situation in which increased global cooperation supports these efforts. Things Go Wrong models a world in which air quality worsens, smoking and obesity rates increase and there is little international cooperation on addressing these challenges.&lt;br /&gt;

HIV and AIDS have attracted significant interest among policy makers because of the tremendous toll that these diseases have on populations in both human and economic terms. Because of this interest, it is worth discussing the HIV/AIDS submodule separately from the rest of the health module. That submodule represents both the extent of HIV prevalence in a population (a stock variable) and the annual deaths from AIDS (a flow variable driven in substantial part by the prevalence rate, but also responsive to technological advance in the fight against AIDS). A number of key variables are available to represent the burden of HIV and AIDS within a country. &lt;br /&gt;
&lt;br /&gt;
Three variables are key to understanding the progression of infection within a country. &#039;&#039;&#039;HIVCASES&#039;&#039;&#039; provides the total number of HIV cases, &#039;&#039;&#039;HIVRATE&#039;&#039;&#039; represents a flow variable showing the rate at which people are being infected with HIV, and &#039;&#039;&#039;HIVTECCNTL&#039;&#039;&#039; indicates the progress being made in reducing the rate of infection within a country. &lt;br /&gt;
&lt;br /&gt;
Three other variables assess mortality due to HIV and AIDs within a country. Similar to HIV, the variables &#039;&#039;&#039;AIDSDTHS&#039;&#039;&#039; and &#039;&#039;&#039;AIDSDRATE&#039;&#039;&#039; indicate the number of AIDs deaths and the rate of mortality from AIDs respectively, while &#039;&#039;&#039;AIDSDTHSCM&#039;&#039;&#039; represents the cumulative number of deaths due to the disease.&lt;br /&gt;

&lt;br /&gt;
Modifying the infection rate with &#039;&#039;&#039;hivm&#039;&#039;&#039; is probably the easiest way to adjust the burden of HIV infection within a country. Like &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, &#039;&#039;&#039;hivm&#039;&#039;&#039; is a multiplicative parameter. In other words, increasing the value of the parameter in scenario analysis from 1 to 1.2 represents a 20% increase in the rate of infection relative to the base case. &#039;&#039;&#039;Hivtadvr&#039;&#039;&#039; allows users to change the prevalence of HIV, once the epidemic has peaked, by a certain percent annually to model different assumptions about the rate at which control technologies will improve, reducing the prevalence of the disease over time. Unlike the mortality multiplier, which takes effect once the model has calculated the base Variable Name Description HIVCASES Number of HIV cases HIVRATE HIV infection rate HIVTECCNTL Rate of technical control of infection, cumulative reduction in infection rate AIDSDTHS Number of AIDS deaths AIDSDRATE Death rate from AIDS AIDSDTHSCM Cumulative Number of AIDS deaths since first year of model 22 case, this parameter will affect the actual calculations the model makes while running. This parameter functions as additive factor to a growth rate within IFs. In other words, a 0.01 increase in the parameter represents a 0.01 increase in the growth rate for the technical advance rate in HIV infection control (&#039;&#039;&#039;hivtadvr&#039;&#039;&#039;). &lt;br /&gt;
&lt;br /&gt;
The HIV submodule is designed to allow users to affect the course of the epidemic across countries and across time. The multiplier &#039;&#039;&#039;hivmdcm&#039;&#039;&#039; is a multiplicative parameter that affects the maximum infection rate in middleincome developing countries. Another way to alter the course of the epidemic is by manipulating the coefficient on &#039;&#039;&#039;hivpeakr&#039;&#039;&#039;, which is an additive parameter that will increase the peak rate of infection over the course of the epidemic. Thus a 0.01 increase in the value of the coefficient represents a 0.01 increase in the peak infection rate. An associated parameter, &#039;&#039;&#039;hivpeakyr&#039;&#039;&#039; sets the date at which the epidemic will peak before the infection rate begins to decline. Changing this parameter in the Scenario Analysis page will allow users to set any year between 2010 and 2100 as the year of peak infection rate depending on their assumptions regarding the technical rate of advance in controlling the disease. Finally, the parameter hivincr controls the increased rate in infection prior to 2000, when our knowledge of the epidemic was much less complete and control efforts were far less effective.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;br /&gt;
Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the [[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate.&lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

&lt;br /&gt;
Three major integrated scenarios on health were developed by the Pardee Center for the health volume of the Patterns of Potential Human Progress series (Hughes et al., 2011). The World Integrated Scenario Sets folder contains the scenarios that were built for this volume, of which three are worth an extended discussion. The first is the Proximate Drivers Excluding Environment folder, which contains parameters to individually alter four of the major risk factors for several causes of mortality. These are Body Mass Index which is a risk factor for cardiovascular disease; under nutrition, which is a risk factor for communicable diseases; smoking which is a risk factor for respiratory disease; and large increases in the number of cars per person coupled with poor pedestrian safety, which is a major risk factor for accidental death. This scenario also includes increased to improved water sources and piped sanitation taken from the infrastructure module, and parameters to reduce environmental exposure to poor air quality. This scenario reduces these risk factors to their theoretical minima, to simulate aggressive efforts to reduce, high BMI, the obesity rate, childhood malnutrition, smoking, and traffic mortality. Malnutrition is set to 0.01, smoking and obesity multipliers are set to 0, BMI multiplier to 0.8, vehicle fleets to 0.5, and traffic mortality to 0. &lt;br /&gt;
&lt;br /&gt;
Another important pair of prepackaged scenarios contains the optimistic Luck and Enlightenment scenario, and a scenario that considers what happens when Things Go Wrong. The Luck and Enlightenment scenario includes improvements to HIV/AIDS, sanitation access, improved air quality, and reduced smoking rates which help lower the burden of NCDs. It also features changes to the burden of communicable disease designed to increase the levels of these. A variation to Luck and Enlightenment has add-ins that also increase foreign aid donations and agricultural yields, effectively modeling a situation in which increased global cooperation supports these efforts. Things Go Wrong models a world in which air quality worsens, smoking and obesity rates increase and there is little international cooperation on addressing these challenges.&lt;br /&gt;

HIV and AIDS have attracted significant interest among policy makers because of the tremendous toll that these diseases have on populations in both human and economic terms. Because of this interest, it is worth discussing the HIV/AIDS submodule separately from the rest of the health module. That submodule represents both the extent of HIV prevalence in a population (a stock variable) and the annual deaths from AIDS (a flow variable driven in substantial part by the prevalence rate, but also responsive to technological advance in the fight against AIDS). A number of key variables are available to represent the burden of HIV and AIDS within a country. &lt;br /&gt;
&lt;br /&gt;
Three variables are key to understanding the progression of infection within a country. &#039;&#039;&#039;HIVCASES&#039;&#039;&#039; provides the total number of HIV cases, &#039;&#039;&#039;HIVRATE&#039;&#039;&#039; represents a flow variable showing the rate at which people are being infected with HIV, and &#039;&#039;&#039;HIVTECCNTL&#039;&#039;&#039; indicates the progress being made in reducing the rate of infection within a country. &lt;br /&gt;
&lt;br /&gt;
Three other variables assess mortality due to HIV and AIDs within a country. Similar to HIV, the variables &#039;&#039;&#039;AIDSDTHS&#039;&#039;&#039; and &#039;&#039;&#039;AIDSDRATE&#039;&#039;&#039; indicate the number of AIDs deaths and the rate of mortality from AIDs respectively, while &#039;&#039;&#039;AIDSDTHSCM&#039;&#039;&#039; represents the cumulative number of deaths due to the disease.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

| style=&amp;quot;width: 93px;&amp;quot; | Limit&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;br /&gt;
Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the [[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate.&lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

&lt;br /&gt;
Three major integrated scenarios on health were developed by the Pardee Center for the health volume of the Patterns of Potential Human Progress series (Hughes et al., 2011). The World Integrated Scenario Sets folder contains the scenarios that were built for this volume, of which three are worth an extended discussion. The first is the Proximate Drivers Excluding Environment folder, which contains parameters to individually alter four of the major risk factors for several causes of mortality. These are Body Mass Index which is a risk factor for cardiovascular disease; under nutrition, which is a risk factor for communicable diseases; smoking which is a risk factor for respiratory disease; and large increases in the number of cars per person coupled with poor pedestrian safety, which is a major risk factor for accidental death. This scenario also includes increased to improved water sources and piped sanitation taken from the infrastructure module, and parameters to reduce environmental exposure to poor air quality. This scenario reduces these risk factors to their theoretical minima, to simulate aggressive efforts to reduce, high BMI, the obesity rate, childhood malnutrition, smoking, and traffic mortality. Malnutrition is set to 0.01, smoking and obesity multipliers are set to 0, BMI multiplier to 0.8, vehicle fleets to 0.5, and traffic mortality to 0. &lt;br /&gt;
&lt;br /&gt;
Another important pair of prepackaged scenarios contains the optimistic Luck and Enlightenment scenario, and a scenario that considers what happens when Things Go Wrong. The Luck and Enlightenment scenario includes improvements to HIV/AIDS, sanitation access, improved air quality, and reduced smoking rates which help lower the burden of NCDs. It also features changes to the burden of communicable disease designed to increase the levels of these. A variation to Luck and Enlightenment has add-ins that also increase foreign aid donations and agricultural yields, effectively modeling a situation in which increased global cooperation supports these efforts. Things Go Wrong models a world in which air quality worsens, smoking and obesity rates increase and there is little international cooperation on addressing these challenges.&lt;br /&gt;

&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;

In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;br /&gt;
Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the [[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate.&lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;br /&gt;
Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;br /&gt;
Aside from the direct and indirect parameters affecting health, the distal drivers of health include per capita GDP, years of education, and technology. Per capita GDP is an element of the {[Economics#Economics|economic module]] and can be changed in a number of ways, but especially by changing the elements that make up multifactor productivity. Years of education is an element of the [[Education#Education|education module]] and can be changed by altering the duration of schooling, and the completion rate. &lt;br /&gt;
&lt;br /&gt;
Moving to the third distal driver of health, there are a number of parameters built into the health module that can be used to alter the rate of technological change. &#039;&#039;&#039;Hlmortmodsw&#039;&#039;&#039; is a master switch that, when set to 1 as in the Base Case default, reduces technological progress for low-income countries of Africa, Europe, Southeast Asia, and West Pacific based on geographic and income categories. There are parameters available to alter these assumptions about differentials in mortality declines in these regions, but they only have an effect in the base case; when &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 0 these parameters have no impact.&lt;br /&gt;
&lt;br /&gt;
Once &#039;&#039;&#039;hlmortmodsw&#039;&#039;&#039; is set to 1, users can manipulate mortality patterns through several parameters. Hltechshift, alters the rate of change for health technology impacts relative to GDP. The &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter allows users to change the mortality rate using a shift parameter that alters the technology factor affecting mortality decline relative to initial GDP. &#039;&#039;&#039;Hltechlinc&#039;&#039;&#039; and &#039;&#039;&#039;hltechssa&#039;&#039;&#039; can be used to change the rate of technological advance resulting in mortality decline in low-income countries (&#039;&#039;&#039;hltechlinc&#039;&#039;&#039;) and sub-Saharan Africa (hltechssa) specifically. Meanwhile, the &#039;&#039;&#039;hltechbase&#039;&#039;&#039; parameter allows users to change the base level of technological change across the 20 world, rather than country by country as you can do using the &#039;&#039;&#039;hltechshift&#039;&#039;&#039; parameter. All of these parameters pertain to all causes of mortality except cardiovascular mortality, which uses a different regression equation.&lt;br /&gt;

The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;

A number of alternative scenarios come prepackaged with the model. To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;br /&gt;
Only a small set of parameters allow users to affect injuries and accidents, and these primarily revolve around reducing traffic deaths. Users may reduce traffic deaths as a ratio of the number of vehicles in a country using either a multiplier, &#039;&#039;&#039;deathtrpvm&#039;&#039;&#039;, or a pair of standard error targeting parameters, &#039;&#039;&#039;deathtrpvsetar&#039;&#039;&#039; and &#039;&#039;&#039;deathtrpseyrtar&#039;&#039;&#039;. Standard error targeting is discussed in detail in the [[Infrastructure#Infrastructure|infrastructure module]]. These parameters allow users to model the impact of road safety on mortality and, by extension, on economic productivity.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;br /&gt;
&#039;&#039;&#039;Hlsmokingm&#039;&#039;&#039; is a multiplicative parameter that will change the rate of smoking, which will affect the prevalence of respiratory diseases. &#039;&#039;&#039;Envpm2pt5m&#039;&#039;&#039; is a multiplicative parameter that will change the level of ambient environmental pollution in terms of parts per million; higher levels of environmental pollution are a risk factor for both communicable and non-communicable respiratory diseases. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;Hlobesitym&#039;&#039;&#039; works similarly to affect the prevalence of obesity within a society in the absence of overall caloric intake changes. This parameter can be used to model the impact of changing levels of physical activity within a society. Both of the above parameters work similarly to other multiplicative parameters: increasing the value of the parameter to 1.2 from 1, represents a 20% increase in the value of the parameter over the base case. By the same token, users can use &#039;&#039;&#039;hlbmim&#039;&#039;&#039; to affect the body mass index in a country, a major risk factor for cardiovascular diseases, diabetes, and overall morbidity. Please note: &#039;&#039;&#039;hlobesitym&#039;&#039;&#039; affects only obesity rates and has no affect on health; in contrast, &#039;&#039;&#039;hlbmim&#039;&#039;&#039; will affect body mass index, obesity, and deaths from heart disease and diabetes.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[Agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[Infrastructure#Infrastructure|infrastructure module]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[Infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

Above are a number of the parameters that users may wish to use to manipulate communicable diseases (which predominantly affect children). &#039;&#039;&#039;Ylm&#039;&#039;&#039; is a multiplicative parameter in the [[agriculture_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;agriculture module&amp;lt;/span&amp;gt;]] that can be used to change the yield of agricultural lands within a country, affecting the number of calories available for consumption, and thereby altering the rates of malnutrition and obesity. &#039;&#039;&#039;Watsafem&#039;&#039;&#039; and &#039;&#039;&#039;sanitationm&#039;&#039;&#039;, in the [[infrastructure_module|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure module&amp;lt;/span&amp;gt;]], influence the percentage of the population that has access to safe water and sanitation respectively, thus decreasing childhood exposure to diarrheal disease, malnutrition and premature death. Other parameters to control safe water and sanitation access are discussed in the [[infrastructure|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;infrastructure&amp;lt;/span&amp;gt;]] section of the model. Finally, although HIV is more thoroughly discussed in the [[HIV/AIDs_submodule|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDs submodule&amp;lt;/span&amp;gt;]], one brute force parameter is worth noting here. &#039;&#039;&#039;Hivm&#039;&#039;&#039; allows users to directly affect the rate of infection with the HIV virus.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;br /&gt;
The above parameters provide simple ways to directly affect the burden of disease within a country. The most important parameter for modifying mortality rates is &#039;&#039;&#039;hlmortm&#039;&#039;&#039;, a parameter that allows users to increase or decrease the prevalence of deaths in any particular category of illness. IFs modifies mortality in the following categories: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Altering the mortality burden will affect the variables &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, and &#039;&#039;&#039;HLDALYs&#039;&#039;&#039;. The parameter will indirectly affect morbidity because of its direct link to mortality. In the case of Mental Health Diseases, the parameter will not have much impact on &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, but may have a significant impact on the number of DALY’s experienced by a population. Because &#039;&#039;&#039;hlmortm&#039;&#039;&#039; is a multiplier, increasing its value from 1 to 1.2 represents a 20% increase in the burden of mortality from a particular cause. A similar parameter, &#039;&#039;&#039;hlmorbm&#039;&#039;&#039;, allows users to affect morbidity directly through a brute force multiplicative parameter. This allows users to affect the years lost to disability in a working life and by extension multifactor productivity due to human capital (&#039;&#039;&#039;MFPHC&#039;&#039;&#039;). The &#039;&#039;&#039;hlstddthsw&#039;&#039;&#039; allows users to switch between displaying DEATHCAT in absolute numbers to deaths per thousand people.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

The primary variables of interest in the IFs health module are those that pertain to mortality and morbidity due to a variety of causes. &#039;&#039;&#039;LIFEXP&#039;&#039;&#039; and &#039;&#039;&#039;CDR&#039;&#039;&#039;, discussed in the population module, provide basic measures of population health. &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; provides a measure of the number of deaths (in thousands) due to different categories of mortality. IFs can display health variables in the following categories of disease: Other Communicable Disease, Malignant Neoplasm, Cardiovascular, Digestive, Respiratory, Other NonCommunicable Diseases, Unintentional Injuries, Intentional Injuries, Diabetes, AIDs, Diarrhea, Malaria, Respiratory Infections, and Mental Health. Using the Flexible Display form, it is also possible to see many of these variables in the rolled-up categories of Communicable Disease, Non-Communicable Disease, and Injuries or Accidents. Because different health conditions affect age cohorts differentially, the above measure is insufficient in understanding the full impact of ill health. For this reason, it is also possible to break down the actual number of deaths accruing to each cohort, sex, and cause via the Specialized Display menu under the health heading. For example, both the Mortality by Age, Sex, and Cause and the J-Curve displays provide useful information about the health status of a country. &lt;br /&gt;
&lt;br /&gt;
Three other measures help to enrich the picture: &#039;&#039;&#039;HLYLL&#039;&#039;&#039;, &#039;&#039;&#039;HLYLD&#039;&#039;&#039; and &#039;&#039;&#039;HLDALY&#039;&#039;&#039;. Like &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039;, these aggregate (across age-cohort) measures are available by cause and country. &#039;&#039;&#039;HLYLL&#039;&#039;&#039; is a measure of the number of life years lost due to premature death. It differs from the &#039;&#039;&#039;DEATHCAT&#039;&#039;&#039; variable because it represents the burden of premature mortality In terms of life years lost, which allows us to account for the fact that some diseases, like HIV/AIDS, primarily affect younger people, while others, like cardiovascular disease, are primarily fatal in older adults. Although the total number of deaths may be the same between two countries for each cause, there may be significant differences between two countries’ health profiles in terms of YLLs. &lt;br /&gt;
&lt;br /&gt;
&#039;&#039;&#039;HLYLD&#039;&#039;&#039; is another measure that represents the burden of ill health in terms of life years of impact. It indicates the burden of years lived with disability or disease. In calculating YLD, IFs uses the disability weights that WHO created to rank the relative severity of different conditions and their impact on productivity. &lt;br /&gt;
&lt;br /&gt;
Finally, Disability Adjusted Life Years (DALYs) are a measure of morbidity (disability or infirmity due to ill health). &#039;&#039;&#039;HLDALY&#039;&#039;&#039; sums YLLs and YLDs to create a measure of the number of years of life lost to both premature mortality and morbidity due to ill health. Like the other measures discussed above, DALYs can be broken down by different disease categories within IFs. The DALY is probably the most expansive measure of ill-health within a population because it includes mortality burden by age of death and the lost quality of life for those who did not die from health events, but who are disabled by them in some way.&lt;br /&gt;
&lt;br /&gt;
Other measures provide indicators of health in regard to certain specific risk factors for disease or among certain segments of the population. Infant mortality, &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, can be used to assess the burden of ill health among children under one year of age. &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039;, displays the percentage of the population who are stunted (have low height for age),while &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; and &#039;&#039;&#039;MALNPOPP&#039;&#039;&#039;, provide information on the percentage of the child and adult population who are malnourished respectively. The variables &#039;&#039;&#039;INFMOR&#039;&#039;&#039;, &#039;&#039;&#039;HLSTUNT&#039;&#039;&#039; and &#039;&#039;&#039;MALNCHP&#039;&#039;&#039; are especially useful for assessing the burden of ill health due to communicable diseases and other conditions that primarily affect children. By contrast, the variables &#039;&#039;&#039;HLBMI&#039;&#039;&#039;, &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039;, and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide risk factor information on diseases that affect primarily adults. HLBMI represents the body mass index in a country while &#039;&#039;&#039;HLOBESITY&#039;&#039;&#039; and &#039;&#039;&#039;HLSMOKING&#039;&#039;&#039; provide information on the percentage of the population that is obese or smokes. &lt;br /&gt;
&lt;br /&gt;
Other variables that will be useful to users interested in specific conditions or subpopulations include indicators on stunting and BMI, as well as smoking and obesity. Variables for HIV/AIDS are also available and discussed separately below in the subsection on the [[HIV/AIDS|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;HIV/AIDS&amp;lt;/span&amp;gt;]] sub-module.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

Originally created for the poverty volume of the Pardee Center’s Potential Patterns of Human Progress (PPHP) series, the two files are located in the Framing Scenarios folder under Population. Both scenarios feature the direct total fertility rate multiplier. &#039;&#039;&#039;Tfrm&#039;&#039;&#039; in the high fertility scenario is set to 1.5 globally. In the low fertility scenario, &#039;&#039;&#039;tfrm&#039;&#039;&#039; is set to .6 in non-OECD nations, and the limit parameter &#039;&#039;&#039;tfrmin&#039;&#039;&#039; is set to 1.6 globally. Although the two scenarios only feature a few interventions, the effects of such a large change in human reproductive behavior would have significant forward linkages throughout each of the model’s systems.&lt;br /&gt;
&lt;br /&gt;
Four of the prepackaged scenarios located in the folder Interventions and Agent Behavior contain additional examples of the demographic module’s parameters: Non OECD Contraception Use Slowed, Non OECD Contraception Use Accelerated, World Migration High, and World Migration Low. The pair of scenarios focusing on contraceptive usage rates both utilize &#039;&#039;&#039;contrusm&#039;&#039;&#039;. In the accelerated scenario, the multiplier takes the value 1.2 in non-OECD nations; and the value 0.8 in the slowed scenario for all non-OECD nations. The two alternate migration scenarios similarly feature interventions on a single parameter: the global migration multiplier &#039;&#039;&#039;wmigrm&#039;&#039;&#039;. In the high scenario the parameter takes on a value of 2, doubling global migration flows; and in the low scenarios flows are halved, with &#039;&#039;&#039;wmigrm&#039;&#039;&#039; declining to a value of 0.5.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

| style=&amp;quot;width: 93px;&amp;quot; | Limit&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

In addition to manipulating the rate at which populations grow, users can experiment with the effects of changing a country’s working age, something that will be fiscally important in many countries as populations age. The variables &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039; and &#039;&#039;&#039;POPRETIRE&#039;&#039;&#039; map the typical age structure of a country or region’s work force. Two parameters, &#039;&#039;&#039;workingageentry&#039;&#039;&#039; and &#039;&#039;&#039;workingageretire&#039;&#039;&#039;, control the age at which a person is considered eligible for work and the age at which a person is eligible for retirement. Changes in the workforce’s age configuration link forward to economic production via the size of the labor force (&#039;&#039;&#039;LAB&#039;&#039;&#039;). Raising or lowering the retirement age will additionally affect government finances via the size of population of retirement age and the level of pension support provided to households (&#039;&#039;&#039;GOVHHPENT&#039;&#039;&#039;).&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;br /&gt;
Users interested in modifying migration patterns should bear in mind that migrant flows are subject to an accounting system that keeps the global number of net migrants equal to zero. In other words, a person leaving one country will be accounted for when they enter another country. Changing the world migration rate, &#039;&#039;&#039;wmigrm&#039;&#039;&#039;, is the easiest way to affect migration patterns in IFs. Altering this parameter will allow users to increase the overall rate at which migration occurs at a global level, enabling users to simulate large scale increases (or decreases) in migration generated by, say, reductions in visa fees, or the opening of borders as is the case in the EU’s Schengen area. The parameter &#039;&#039;&#039;migrater&#039;&#039;&#039;, on the other hand, allows users to affect the rate of migration into individual countries or regions (values can range from positive, indicating net inward migration, to negative, indicating net outward migration).&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Prepackaged Scenarios&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
A number of alternative scenarios come prepackaged with the model. To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

The [[health_module_write-up|&amp;lt;span style=&amp;quot;background-color:#FFFF00;&amp;quot;&amp;gt;health module write-up&amp;lt;/span&amp;gt;]] includes a full description of the drivers of mortality in the IFs system, and explains how to manipulate each one. However, one parameter affecting mortality, &#039;&#039;&#039;mortm&#039;&#039;&#039;, is worth discussing separately. 14 This parameter functions similarly to the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; parameter available in the health module, but does not disaggregate by cause of death. Similar to &#039;&#039;&#039;tfrm&#039;&#039;&#039;, &#039;&#039;&#039;mortm&#039;&#039;&#039; can be used to model the impact of events that have broad impacts across the population, such as the end of an armed conflict or the implications of a plague. Usually however, if a user is building a scenario analyzing health trends, using the &#039;&#039;&#039;hlmortm&#039;&#039;&#039; multiplier will be more useful because it disaggregates mortality on the basis of cause. Because morbidity rates in IFs are linked normally to mortality rates, these parameters will affect them also.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

| style=&amp;quot;width: 93px;&amp;quot; | Limit&lt;br /&gt;
|}&lt;br /&gt;
&lt;br /&gt;
The single most powerful way for users to modify fertility rates is to manipulate &#039;&#039;&#039;tfrm&#039;&#039;&#039;, a parameter that directly alters the total fertility rate within a country or region. This parameter serves as a multiplier on the fertility rate calculated by the model—a 20% increase or decrease in the value of the parameter will result in a similar magnitude of change in the value of the associated variable, &#039;&#039;&#039;TFR&#039;&#039;&#039;. Because it is a brute force multiplier, users should justify their modifications to the parameter. When used thoughtfully, &#039;&#039;&#039;tfrm&#039;&#039;&#039; can be a powerful tool for scenario analysis. It can be used to model the impact of fertility control initiatives that extend beyond simple contraceptive use. An example would be the implementation of a program to offer public seminars on the benefits of having fewer children, which could lower the fertility rate even when overall contraceptive usage rates are low. Health care programs for women are a major contributor to fertility decline. &lt;br /&gt;
&lt;br /&gt;
Users can also directly change the percentage of the population that uses contraceptives via &#039;&#039;&#039;contrusm&#039;&#039;&#039;, a parameter that indirectly affects the total fertility rate via &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;. As this is a multiplier, it works the same way as tfrm. It can be used to model the impact of an increase in the availability of family planning education, a campaign to promote the use of condoms, or any other intervention that would likely increase (or decrease) the percentage of a population using contraceptives. Additionally, the parameter &#039;&#039;&#039;eltfrcon&#039;&#039;&#039; allows users to control the elasticity of total fertility to contraceptive use. For example, a weaker relationship between the two variables might be justified if the contraceptive methods in use in a country or region are widely known to have high failure rates. &lt;br /&gt;
&lt;br /&gt;
When creating alternative scenarios that span long time horizons, users may wish to modify fertility assumptions built into the demographic module. As countries grow richer and reach higher levels of educational attainment, total fertility rates tend to decrease. However, in forecast years, a minimum value prevents countries from dipping too far below replacement rate. As a default setting, the minimum parameter, &#039;&#039;&#039;tfrmin&#039;&#039;&#039;, is set to 1.9. Thus, in the Base Case, &#039;&#039;&#039;TFR&#039;&#039;&#039; in highly developed countries will converge to just below 2 children per woman. By increasing or decreasing the parameter, users can experiment with different long-term fertility patterns.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

A number of alternative scenarios come prepackaged with the model. To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;

&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
The final proximate driver of population growth is migration. &#039;&#039;&#039;MIGRANTS&#039;&#039;&#039; measures net migrants in raw figures, reported in millions of people; but this variable is determined by &#039;&#039;&#039;MIGRATE&#039;&#039;&#039;, the net migration rate, reported as percent of the total population. The basic forecasts of migration in IFs are one of the very few variables that are exogenous. Nonetheless, there is parametric control of it.&lt;br /&gt;
&lt;br /&gt;
The demographic module features an array of parameters that allow users to create alternative demographic scenarios by exploring uncertainty surrounding: fertility, mortality and migration, as well as the years making up people’s working lives.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Prepackaged Scenarios&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
A number of alternative scenarios come prepackaged with the model. To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;

The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate.&lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
The three immediate drivers of population change—births, deaths and migration—are captured in the model as flows. Every year babies are born (&#039;&#039;&#039;BIRTHS&#039;&#039;&#039;), people die (&#039;&#039;&#039;DEATHS&#039;&#039;&#039;) and people leave countries to live elsewhere (&#039;&#039;&#039;MIGRANTS&#039;&#039;&#039;). These processes alter the stock of population in countries, regions and the world as a whole. The speed at which a population will grow or decline, and the attendant shift in a population’s age structure, depend on crude birth rates (&#039;&#039;&#039;CBR&#039;&#039;&#039;) and crude death rates (&#039;&#039;&#039;CDR&#039;&#039;&#039;)—the number of births and deaths per 1,000 people.&lt;br /&gt;
&lt;br /&gt;
Each of the immediate drivers is linked to deeper determinants of population. For instance, fertility rates are responsive to income, education and infant mortality rates, offering points of access elsewhere in the model. Total Fertility Rate (&#039;&#039;&#039;TFR&#039;&#039;&#039;) is a variable that is essential to our understanding of populations’ reproductive behavior. &#039;&#039;&#039;TFR&#039;&#039;&#039; is, essentially, the number of children the average woman in a country can expect to have over the course of her lifetime. In order for the overall population size to remain roughly stable, &#039;&#039;&#039;TFR&#039;&#039;&#039; must meet the replacement rate for that country. For developed countries this is approximately 2.1 children per woman, but the figure may be higher in countries with high mortality rates, and is lower in many. While &#039;&#039;&#039;TFR&#039;&#039;&#039; largely determines future population growth, it is not the only behavioral variable of note: &#039;&#039;&#039;CONTRUSE&#039;&#039;&#039; captures the percent of fertile women who routinely use some method of contraception.&lt;br /&gt;
&lt;br /&gt;
For a complete discussion of mortality see the [[Health#Health|Health module]], where deaths are computed. They are responsive to deep or distal factors such as income, education and technological advance, as well as to more proximate ones such as levels of undernutrition and smoking. A key indicator for the population model, linked to deaths, is LIFEXP, or life expectancy, which provides a measure of the median life expectancy of a newborn in a particular year given the current mortality distribution. Although life expectancy can be calculated for any age, IFs focuses on life expectancy at birth. This variable is key to the functioning of the IFs system because many of the parameters that affect mortality do so by changing life expectancy.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Prepackaged Scenarios&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
A number of alternative scenarios come prepackaged with the model. To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;
&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Variables of Interest&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
The IFs demographic module breaks country populations down into 21 fiveyear age groups, each one subdivided by gender. This allows the model to create an age-sex cohort structure that responds to changes in the three fundamental drivers of population: fertility, mortality, and migration. Births are calculated as a function of each country’s fertility distribution and age distribution. As children are born, they enter the lowest band of the agesex structure, the layer representing people aged 0 through 5. Each country’s population growth is reduced by deaths at each age level; like births, deaths are calculated as a function of the mortality distribution and the age distribution. Finally, migration patterns either add to, or subtract from, each country’s population, depending on the balance of immigration and emigration&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt; . Each of the three proximate drivers of population is influenced by deeper social processes: births are a product of fertility patterns; deaths are linked to life expectancy; and net migrants are determined by an overall global migration rate. &lt;br /&gt;
&lt;br /&gt;
Total population is represented in millions of people via &#039;&#039;&#039;POP&#039;&#039;&#039;, but users may also choose to explore the age structure within society. Three variables break population down into broad age groups: &#039;&#039;&#039;POPLE15&#039;&#039;&#039;, people age 15 or younger, &#039;&#039;&#039;POP15TO65&#039;&#039;&#039;, people age 15 to age 65, and &#039;&#039;&#039;POPGT65&#039;&#039;&#039;, people older than age 65. Three additional variables provide a similar disaggregation of population: &#039;&#039;&#039;POPPREWORK&#039;&#039;&#039;, &#039;&#039;&#039;POPWORKING&#039;&#039;&#039;, &#039;&#039;&#039;POPRETIRED&#039;&#039;&#039;—as the names suggest, they measure the number of people who have yet to enter their working years, the number of people currently in their working years, and the number of people who have completed their working years. The years comprising an adult’s working life may vary from country to country, depending on education systems and retirement ages. Users can explore additional population characteristics via the variables &#039;&#039;&#039;YTHBULGE&#039;&#039;&#039;, the percent of all adults (15 and older) between the ages 15 and 29; &#039;&#039;&#039;POPMEDAGE&#039;&#039;&#039;, the median age of a country’s population; and &#039;&#039;&#039;LAB&#039;&#039;&#039;, the size of the labor force, recorded in millions of people. For any country, the complete age and sex breakdown is available under the Specialized Displays for Issues option under the Display sub-menu. From the Specialized Displays menu, select Population by Age and Sex, and click the button labeled Show Numbers. This will bring up detailed population figures for any of the countries in the IFs system. To view a population pyramid display, toggle the Distribution Type setting on the menu bar.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;3&amp;lt;/sup&amp;gt;In IFs, the age distribution of migrants is controlled by an internal vector across age categories, not available for manipulation through the model’s front-end.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;

&lt;br /&gt;
A number of alternative scenarios come prepackaged with the model. To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&lt;br /&gt;

To access them, select Scenario Analysis from the main menu, and then the option labeled Quick Scenario Analysis with Tree. Once in the scenario display, select Add Scenario Component to view all of the .sce (scenario) files that are stored on your computer normally at the path C:/Users/Public/IFs/Scenario. Exploring several simple interventions contained in the folder structure should give users an overview of some of the leverage points in that they may wish to use in each module&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Keys to Successfully Modifying Parameters in IFs&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
*&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; Test all parameter changes individually before building combinations, in order to be able to identify which parameters are having specific impacts&lt;br /&gt;
*After changing a parameter value and running a scenario, check the impact on the most proximate or closely related variables (identified in the tables of each module section), before checking the secondary impacts of your selected parameter on more distally related variables &lt;br /&gt;
*Tie parameter changes to policy options, empirical knowledge, or theoretical insight identified in literature &lt;br /&gt;
*Bear in mind the relevant geographical level at which a parameter operates; some parameters function directly at a global level (e.g., global migration rates), while others will be most relevant at the regional, or national level &lt;br /&gt;
*Some parameters are only effective when used in combination with one another (such as target values and years to reach a target) &lt;br /&gt;
*Some parameters cancel one another out; for example, trgtval and setar parameters cannot be used together except under very limited circumstances that we attempt to note in the subsequent text &lt;br /&gt;
*In many cases, variables affected by certain parameters have natural maximums (e.g. 100 percent) or minimums (e.g. fertility rate), so that changes to the parameters affecting them, where countries may already be approaching such a limit, will not have a significant impact &lt;br /&gt;
*The IFs systems contains many equilibrating processes, such as those around prices; interventions meant to affect one side of such an equilibration (such as efforts to reduce energy demand) may have offsetting effects (such as lower prices for energy and resultant demand increase) that make it harder than you expect to push the system in the desired direction; real-world policy makers often face such difficulties and may need to push harder than anticipated&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case.

&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;

== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Manipulating Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;You will typically manipulate parameters to create scenarios or internally coherent stories about the future. You may create scenarios because you wish to represent and explore the possible impact of policy interventions. Or your stories may represent views of the dynamics of global systems alternative to that in the IFs Base Case scenario. Most of the time, you will be interested in tracking the possible futures of selected variables having particular interest to you. The following sections, each covering a module of the IFs system, begin by identifying some of the variables of potentially greatest interest to you. They then provide suggestions on which parameters are likely to be of most useful in building alternative scenarios for those variables. Each section includes tables listing the most effective parameters with which to target certain outcomes. While these suggestions are intended to help you start to think about which parameters you might use to build your scenarios, it is essential that you consider seriously what the policy-based, empirical-knowledge-rooted, or theoretically informed foundations are for your changes.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt; and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly.&lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&amp;amp;nbsp;parameters are generally paired, one for the target level and one for the number of years to reach the target (from the initial year of the model forecast, 2010). Targets have different types:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Absolute targets&#039;&#039;&#039;. In this case the target value and year define the absolute value the variable should move toward and the number of years after the first model year over which the goal should be achieved. Together they determine a path in which the value for the variable moves quite directly&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt; from the value in first year to the target value in the target year. Trgtval and trgtyr are the parameter suffixes used for this parameter type. The first of these changes the target itself, and the second alters the number of years to the target. The default value of *trgtyr parameters should normally be 10 years, but in some cases it is 0, meaning that users must set the number of years to target as well as the target value in order to use these parameters.&amp;lt;br/&amp;gt;&lt;br /&gt;
:b. &#039;&#039;&#039;Relative (standard error) targets&#039;&#039;&#039;. In this case, the target value and year define a relative value towards which the variable should move and the number of years that will pass before the target is reached. The relative value is defined as the number of standard errors above or below the “predicted” value of the variable of interest (a prediction usually based on the country&#039;s GDP per capita). Target values less than 0 set the target below the typical or predicted (as indicated by cross-sectional estimations) value of the variable. Target values above 0 set the target above the predicted value. As with the absolute targets, the value calculated using relative targeting is compared to the default value estimated in the model. The computed value then gradually moves from the normal or default-equation based value to the target value. If, however, the computed value already is at or beyond the target (that could be above or below depending on whether the target is above or below the default or predicted value), the model will not move it toward the target. Two different parameter suffixes direct relative targeting: &#039;&#039;&#039;setar&#039;&#039;&#039; and &#039;&#039;&#039;seyrtar&#039;&#039;&#039;. The first of these changes the target itself and the second alters the number of years to the target. The default value of the *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; parameters varies based on the module and even variable. Governance parameters are set to a default of 10 years from the year of model initialization, while infrastructure parameters are set to a default of 20 years. These defaults mean that users do not have to change *&#039;&#039;&#039;seyrtar&#039;&#039;&#039; as well as *&#039;&#039;&#039;setar&#039;&#039;&#039; in order to build standard error target scenarios. Changing *&#039;&#039;&#039;setar&#039;&#039;&#039; should be enough.&amp;amp;nbsp;&lt;br /&gt;
&lt;br /&gt;
3.&amp;amp;nbsp;&#039;&#039;&#039;Rates of change&#039;&#039;&#039;. Some parameters specify an annual percentage rate of change. Unfortunately, IFs does not consistently use percentage rates (5 percent per year) versus proportional rates (0.05 increase rate per year, which is equivalent to 5 percent), so the user should be attentive to definitions. There are multiple suffixes that may apply to these, including -&#039;&#039;&#039;r&#039;&#039;&#039; (changes in the rate) and -&#039;&#039;&#039;gr&#039;&#039;&#039; (changes the rate of change, growth or decline).&lt;br /&gt;
&lt;br /&gt;
4. &#039;&#039;&#039;Limits&#039;&#039;&#039;. As indicated for the TFR example, long-term national rates are unlikely to fall and stay below a minimum value. Limits can be minimum or maximum values. These are typically denoted by the suffixes - min, -max, or -lim.&lt;br /&gt;
&lt;br /&gt;
5. &#039;&#039;&#039;Switches&#039;&#039;&#039;. These turn off and on elements in the model. These most often affect linkages between modules, but can also change relationships within modules. They are typically denoted by the suffix -sw.&lt;br /&gt;
&lt;br /&gt;
6. &#039;&#039;&#039;Other parameters&#039;&#039;&#039; in equations and algorithms. Equations within IFs can become quite complicated. The parameter types discussed to this point provide the easiest control over them for most model users. Relatively few users will proceed further with parameters, and to do so will typically require attention to&amp;amp;nbsp;the specific nature of the equation (e.g. whether independent variables are related to dependent ones via linear, logarithmic, exponential or other relationship forms). That is, one would normally need to understand the model via the Help system or other project documentation in order to use them meaningfully and without causing substantial risk of bad model behavior. The sections of this manual will provide very little information about these technical parameters.&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Elasticities&#039;&#039;&#039;: These are relatively common within IFs and specify the percentage change in the dependent variable associate with a percentage change in the independent variable. They are typically prefixed &#039;&#039;&#039;el&#039;&#039;&#039;- or &#039;&#039;&#039;elas&#039;&#039;&#039;-.&lt;br /&gt;
&lt;br /&gt;
:b. Equilibration &#039;&#039;&#039;control parameters&#039;&#039;&#039;. IFs balances supply and demand for goods and services via prices, savings and investment with interest rates, and so on. These processes typically use an algorithmic controller system that responds to both the magnitude of imbalance or disequilibrium and the direction and extent of its change over time (see the Help system descriptions of the model). Although they are not typical elasticities, the two parameters that control each such process usually have the prefix &#039;&#039;&#039;el&#039;&#039;&#039;- and the suffixes -&#039;&#039;&#039;1&#039;&#039;&#039; or -&#039;&#039;&#039;2&#039;&#039;&#039;. Parameters ending with &#039;&#039;&#039;1&#039;&#039;&#039; relate to disequilibrium magnitude; and parameters end with &#039;&#039;&#039;2&#039;&#039;&#039; relate to the direction of change.&lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Other coefficients in equations&#039;&#039;&#039;. Beyond elasticities, many other forms of parameter can manipulate an equation. When analysts in many fields think of parameters, this is what they mean. In IFs, most users will use them quite rarely because, in the absence of knowledge concerning equation forms and reasonable ranges, the parameters often have little transparent meaning—experts in a field may use them more often. Many analysts think of such parameters as having a constant value over time, and some are unchangeable over time in IFs. IFs allows almost all, however, to be entered as time series and vary with great flexibility across time. Some can be changed for each country and/or sub-dimensions of the associated variable, such as energy types, but others can only be changed globally.&lt;br /&gt;
&lt;br /&gt;
:d. &#039;&#039;&#039;Equation forms&#039;&#039;&#039;. Although most users will change parameters using the Scenario Tree (see again the Training Manual), the IFs model has made it possible over time to change an increasing number of functions directly (both bivariate and multivariate ones). The advantage this confers is the ability to alter the nature of the formulation (e.g. going from linear to logarithmic) and even, to a very limited degree, the independent or driver variables in the equation. Although some module discussions will occasionally suggest this option, most users will not avail themselves of it. Users who wish to make such changes can do so via the Change Selected Functions options, which can be accessed from the Scenario Analysis Menu on the main page.&amp;lt;br/&amp;gt;&lt;br /&gt;
&lt;br /&gt;
7. &#039;&#039;&#039;Initial conditions&#039;&#039;&#039; for endogenous variables and convergence of initial discrepancies&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Initial conditions &#039;&#039;&#039;are not, strictly speaking, true parameters, but should reflect data. Yet some users will believe that they have data superior to that in IFs, and the system allows the user to change most initial conditions. After the first year, the model will compute subsequent values internally (endogenously). Initial conditions don’t have a suffix; their names are, in fact, those of the variable itself (e.g., &#039;&#039;&#039;POP&#039;&#039;&#039; for population).&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Convergence speed&#039;&#039;&#039; of initial-condition based discrepancies to forecasting functions. Because initial conditions taken from empirical data often vary from the values that are computed in the estimated equation used for forecasting, the model protects the empirically-based initial condition by computing shift factors that represent that initial discrepancy (they can be additive or multiplicative). For many variables, values rooted in initial conditions in the first model year should converge to the value of the estimated equation over time; convergence parameters control the speed of such convergence. Most model users will never change the convergence speed. These are denoted by the suffixes -cf or -conv.&lt;br /&gt;
&lt;br /&gt;
In the use of all parameters, especially those other than equation result parameters, users will often be uncertain how much it is reasonable to move them—as are often even the model developers. The Scenario Tree form provides some support for judgments on this by indicating high and low alternatives to that of that Base Case. This manual will sometimes provide some additional information.&lt;br /&gt;
&lt;br /&gt;
----&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;1&amp;lt;/sup&amp;gt;Because the nature of the equation or formulation will vary (sometimes a driving variable is linearly linked to the dependent variable, sometimes the equation uses a logarithmic, exponential, or other formulation), the coefficients in the equation cannot invariably or even regularly be interpreted as units of change linked to units of change. You may need to explore the Help system and specific equations to fully understand the relationship. This is one of the key reasons we very often turn to the multipliers and additive factors explained in the next paragraph.&lt;br /&gt;
&lt;br /&gt;
&amp;lt;sup&amp;gt;2&amp;lt;/sup&amp;gt;The movement normally will be linear, except that it is possible to set moving targets that create non-linear progression patterns. In some cases, the model explicitly uses non-linear convergence; e.g. to accelerate movement in early years and then to slow it as the target is approached.&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;Types of Parameters in IFs&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
Equations in IFs have the general form of a dependent or computed variable, as a function of one or more driving or independent variables. Variables, like population and GDP, are the dynamic elements of forecasts in which you are ultimately interested. For instance, total fertility rate or TFR (the number of children a woman has in her lifetime) is a function of GDP per capita at purchasing power parity (&#039;&#039;&#039;GDPPCP&#039;&#039;&#039;), education of adults 15 or more years of age (&#039;&#039;&#039;EDYRSAG15&#039;&#039;&#039;), the use of contraception within a country (&#039;&#039;&#039;CONTRUSE&#039;&#039;&#039;), and the level of infant mortality (&#039;&#039;&#039;INFMORT&#039;&#039;&#039;). In the most general terms the equation is&lt;br /&gt;
&lt;br /&gt;
:&amp;lt;math&amp;gt;TFR=F(GDPPCP,EDYRSAG15,CONTRUSE,INFMORT)&amp;lt;/math&amp;gt;&lt;br /&gt;
&lt;br /&gt;
Parameters of several kinds can alter the details of such a relationship. That is, parameters are numbers (also represented by names in IFs), that help specify the exact relationship between independent and dependent variables in equations or other formulations (including logical procedures called algorithms). For instance, the model may contains different parameters that tell us how much TFR rises or falls per unit change in GDP per 6 capita, education levels, contraception use, and infant mortality;1 and it contains still others to set bounds on the lower and/or upper values of TFR over the long run (obviously TFR should never go negative and probably we will not even want it to go, at least for a long time, to a very low level such as an average of 0.5 children per woman). Some of these parameters are more technical than others in the sense that they may significantly affect the overall stability of the model if users are not very careful with the magnitude or direction of the changes they make; we will focus heavily in this manual on parameters that are easiest to interpret and modify.&lt;br /&gt;
&lt;br /&gt;
In many cases, we are more interested in using a parameter to make a direct change to a variable, rather than indirectly affecting a variable like TFR through one of its drivers. We often refer to this as the &amp;quot;brute force&amp;quot; method of changing a variable, and this can be done by multiplying the entire result of a basic equation like that above by a number, adding something to that result, or simply over-riding the result with an exogenously (externally) specified series of values. In the case of TFR we use the multiplier approach, which is described below. The strengths of this approach should be obvious: it preserves model stability, and makes the model more accessible for users. However, the weakness is that in many instances it is more realistic to affect one of the drivers of TFR rather than TFR directly. &lt;br /&gt;
&lt;br /&gt;
Beyond multipliers, there are many other types of parameters that IFs uses, although we are forced to abandon TFR to provide examples. For instance, a switch parameter may turn on or off a particular formulation in preference to another. A target may specify a value towards which we want a variable to move gradually (we would need to specify both the target level and the years of convergence to it).&lt;br /&gt;
&lt;br /&gt;
Overall, key parameter types are:&lt;br /&gt;
&lt;br /&gt;
1. &#039;&#039;&#039;Equation Result Parameters&#039;&#039;&#039;. Most users will use these parameter types far more often than any other. The three types are:&lt;br /&gt;
&lt;br /&gt;
:a. &#039;&#039;&#039;Multipliers&#039;&#039;&#039;. This most common of all parameter types in scenario analysis comes into play after an equation has been calculated. They multiply the result by the value of the parameter. The default value, i.e. the value for which the parameter has no effect and to which multipliers almost invariably are set in the Base Case, is 1.0. These parameters are usually denoted with the suffix -m at the end of the parameter name.&lt;br /&gt;
&lt;br /&gt;
:b. &#039;&#039;&#039;Additive factors&#039;&#039;&#039;. Like multipliers, these change the results after an equation computation, but add to the result rather than multiplying. The default value is normally 0.0. These are usually denoted with the suffix -add at the end of the parameter name. &lt;br /&gt;
&lt;br /&gt;
:c. &#039;&#039;&#039;Exogenous Specification&#039;&#039;&#039;. Sometimes these parameters override the computation of an equation. In other cases, they are actually substitutes for having an equation; that is, they are actually equivalent to specifying the values of a variable over time for which the model has no equation. This typically means establishing a new exogenous series. They typically will have the name of the variable that they over-ride within their own name.&lt;br /&gt;
&lt;br /&gt;
2. &#039;&#039;&#039;Targets&#039;&#039;&#039;. Especially for the purposes of policy analysis, we often want to force the result of an equation toward a particular value over time (e.g. to achieve the elimination of indoor use of solid fuels). Target&lt;br /&gt;

&lt;div&gt;= &amp;lt;span style=&amp;quot;font-size:xx-large;&amp;quot;&amp;gt;Introduction&amp;lt;/span&amp;gt; =&lt;br /&gt;
&lt;br /&gt;
The purpose of this document is to facilitate the development of scenarios with the International Futures (IFs) system. This document supplements the IFs Training Manual. That manual provides a general introduction to IFs and assistance with the use of the interface (e.g., how do I create a graphic?). In turn, the broader Help system of IFs supplements this manual. It provides detailed information on the structure of IFs, including the underlying equations in the model (e.g., what does the economic production function look like?). This document should help users understand the leverage points that are available to change parameters (and in a few cases even equations) and create alternative scenarios relative to the Base Case scenario of IFs (e.g., how do I decrease fertility rates or increase agricultural production?). It proceeds across the modules of IFs, such as demographic, economic, energy, health, and infrastructure, to (1) identify some of the key variables that you might want to influence to build scenarios and (2) the parameters that you will want to manipulate to affect your variables of interest. The Training Manual will help you actually make the parameter changes in the computer program and the Help system will facilitate your understanding of the structures, equations and algorithms that constitute the model. We begin by introducing the types of parameters within IFs and then proceed to a discussion of variables and parameters within each of the IFs modules.&lt;br /&gt;
&lt;br /&gt;
== &amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;A Note on Parameter Names&amp;lt;/span&amp;gt;&amp;lt;span style=&amp;quot;font-size:x-large;&amp;quot;&amp;gt;&amp;lt;/span&amp;gt; ==&lt;br /&gt;
&lt;br /&gt;
In this manual we will provide the internal computer program names of variables and parameters, as well as their descriptions. Those names are especially important for use of the Self-Managed Display form, which provides model users with complete access to all variables and parameters in the system. Most model use, however, employs the Scenario Tree form to build scenarios and the Flexible Display form to show scenario-specific forecasts, and both of those forms rely primarily on natural language descriptions of variables and parameters. To match the names provided here with the options in those forms, you can use the Search feature from the menu. The Training Manual describes how to use features such as the Flexible Display form to see computed forecast variables in natural language. And it also describes how to use the Scenario Tree form to access parameters in something close to natural language. Nonetheless, it helps very much in the use of those features and the model generally to know the actual variable and parameter names.&lt;br /&gt;
