Economic preprocessor

There are 72 series marked as "economic" in the "group" field that are read into the preprocessor. Most of them come from World_Development_Indicators (WDI). There are quite a few series marked as "IMF GFS 2013 BATCH PULL". There are a lot of data on the informal economy from ILO-WIEGO. Cyber data also appears to be read into DataEcon.

Initializations

Use government consumption and expenditures data to initialize SAM.

Government consumption

• Government consumption (CGovCon) is initialized using SeriesGovCon%GDP.
  • Source: WDI
  • Definition: Government (general) final consumption as % of GDP
  • Data Description- General government final consumption expenditure (formerly general government consumption) includes all government current expenditures for purchases of goods and services (including compensation of employees). It also includes most expenditures on national defense and security, but excludes government military expenditures that are part of government capital formation.
  • If null: "GDP/Capita (PPP) Versus Govt Cons % GDP (" & CStr(BaseYear) & ")"
  • This uses the equation: GDP/Capita (PPP) Versus Govt Cons % GDP (2000)
• CGConFromSectors = GExpDef(ICount%) + GExpEd(ICount%) + GExpRandD(ICount%) + GExpHl(ICount%) + GExpInfra(ICount%) + GExpInfraOther(ICount%)
  • Government consumption by sector is initialized in the Government consumption preprocessor (DataGovCon).
• Set CGovCon as the max of CGovCon and the CGovCon calculated as the sum of sectors. Bound between 9 and 35.

Government expenditures

Initialize central government expenditures and total government expenditures and then calculate local government expenditures as the difference.

• Central government expenditures (GovExpCentral) is initialized using SeriesGovExpense%GDP
  • Source: WDI
  • Definition: Government expense as % of GDP (compare with govt expenditures)
• If null then use SeriesGovtCalcExpendCen%GDP 
• If still null then use: "GDP/Capita (PPP 2005) Versus Govt Expense % GDP (" & CStr(BaseYear) & ") Log"
• This equation uses: GDP/Capita (PPP 2005) Versus Govt Expense % GDP (2010) Log
• Note: IMF series (GovtCalcExpendCen%GDP) appears to be central government expenditures while the WDI series does not specify.

• Use SeriesGovtCalcExpendTot%GDP to initialize total government expenditures.
  • Source: IMF GFS
  • Definition: Expenditure, government, total, as % of GDP
• If null, then use SeriesGovTotalOutlays%GDP
  • Source: OECD Statistics Database Online
  • Definition: Government total outlays (% of GDP), including forecast
• Note: Must make sure these two series are identical
• Hard code 46 in for Ireland in 2010 because of bailout.

• If no data on total expenditures still, then we cannot estimate local so we use this equation:

        If IsNull(CGovTotExp) Then
            CGovExpLocal(ICount%) = 2 + 12 * Amin(20, CGDPPCP(ICount%)) / 20
        Else
            CGovExpLocal(ICount%) = AMAX(1, CGovTotExp - GovExpCentral)
        End If

'   Go to total govt expenditures and filling holes when have data in order to compute local govt
'       When do not have total and therefore ability to compute local govt,
'       estimate at 2-14% of GDP (OECD gap between total and central is 14%)
'       North, Walli, Weingast p. 10 have table showing grows from 1-2% to 16%

• CGovExp(ICount%) = GovExpCentral + CGovExpLocal(ICount%) 'Add Central plus local to get total

Government revenue

• Central government revenue (GovRevCen) is initialized using SeriesGovtCurRev%GDP
  • Source: WDI
  • Definition: Current government revenue as % of GDP
  • Extended definition: blended with old Ifs data.  Revenue is cash receipts from taxes, social contributions, and other revenues such as fines, fees, rent, and income from property or sales. Grants are also considered as revenue but are excluded here.
• If it's null or less than 5 then we use GDP per capita to estimate.
  • To fill holes: "GDP/Capita (PPP) Versus Govt Revenue (" & CStr(BaseYear) & ")"
  • This equation uses: GDP/Capita (PPP) Versus Govt Revenue (2000)

• Total government revenue (GovRevTot) is initialized using SeriesGovtCalcRevTot%GDP
  • Source: IMF GFS
  • Definition: Revenue, government, total, as % of GDP
• If GovRevTot is null i.e. there is no data for total government revenue for the country in SeriesGovtCalcRevTot%GDP (or the value is less than 5) then esimate using GDP per capita (2005).
  • To fill holes: "GDP/Capita (PPP 2005) Versus Govt Revenue Total (2010) Log"
• Then set GovRevTot as the max of total government revenues and central government revenues
• Cap total government revenues at 75
• Set local government revenue as the difference between total and central
• Note:This logic creates problems for countries where there is not a total government revenue data point but there is a central government data point (ex. Malawi). In this case, both total government revenue and central government revenue are initialized as the data value for central government revenue and local government revenue is set at zero (the difference between total and central).

• Firm tax rate (CFirmTaxR) is initialized using SeriesTaxCorp%Tot
  • Source: IMF Government Finance Statistics (2001)
  • Definition: Corporate taxes as percent of total central government revenue
  • Note: Apparently not part of batch pull.
  • To fill holes:"GDP/Capita (PPP) Versus Corporate Tax % of Total (" & CStr(BaseYear) & ")"
  • This equation uses: GDP/Capita (PPP) Versus Corporate Tax % of Total (2000)

• Social security tax (CSSWelTaxR) is initialized using SeriesTaxSocSec%CurRev 
  • Source: WDI
  • Definition: Social security taxes as % of total govt revenue
  • To fill holes: "GDP/Capita (PPP) Versus SS Tax % of Total (" & CStr(BaseYear) & ")"
  • This equation uses: GDP/Capita (PPP) Versus SS Tax % of Total (2000)

• Indirect taxes (CIndirectTaxR) is initialized using SeriesTaxGoodSer%CurRev
  • Source: WDI
  • Definition: Taxes on goods and services as % of total govt revenue
  • To fill holes: "GDP/Capita (PPP) Versus Indirect Tax % of Total (" & CStr(BaseYear) & ")"
  • This equation uses: GDP/Capita (PPP) Versus Indirect Tax % of Total (2000)

• Household taxes (CHHTaxR) estimated as residual from firm, welfare, and indirect taxes

Transfers

CGovSSWel is initialized using SeriesGovSSWelBen%Exp

Source: WDI

Definition: Government Social Security and welfare expenditures as % of total expenditures

Note: Not included in last WDI batch pull

To fill holes: "GDP/Capita (PPP 2005) Versus Govt Expense % GDP (" & CStr(BaseYear) & ") Log"

This equation uses: GDP/Capita (PPP 2005) Versus Govt Expense % GDP (2010) Log

Note: This appears to use a government expense equation to estimate SS and welfare.

            'i.e. protext all of govcon and boost if possible; reduce sswel as needed; reduce govexp after sswel

Pensions

Government pensions (CGovHHPenT) are initalized using SeriesGovtPension%GDP

Note: Newer pension data exists in IFs but is not pulled into preprocessor

To fill holes: "GDP/Capita (PPP) Versus Public Pension % of GDP (" & CStr(BaseYear) & ")"

This equation uses:GDP/Capita (PPP) Versus Public Pension % of GDP (2000)

Allocate total World Bank loans to "advanced countries" (countries with GDP per capita over 10,000 USD and no World Bank loans) based on size of economy. Use one countries share of the total GDP of all advanced countries to determine the share of total WB debt that they lend.

        PerCap = CGDP(ICount%) / CPop(ICount%)
        If PerCap > 10 And CXWBLOANS(ICount%) <= 0.001 Then
            CXWBLOANS(ICount%) = -CGDP(ICount%) / AdvGDPXWBDebt * (GloXWBDebt / AMAX(1, sxwblneqr))

Debt

Initialize public and private guarenteed debt (PPGDEBT) using SeriesXDEBTPPG%GDP

Source: WDI Batch Pull

Definition: External debt, public and publicly guaranteed, as percentage of gross domestic product

Initialize external debt (private non-guarenteed) (PNGDEBT) using SeriesXDEBTPNG%GDP

Source: WDI Batch pull

Definition: External debt, private non-guaranteed, as percentage of gross domestic product

• Assume firm debt (CXFIRMDEBT) is half of the sum of public and private guarenteed and private non-guarenteed.

        CXFIRMDEBT(ICount%) = PNGDEBT + PPGDEBT * 0.5
            'Need to break PPGDEBT better between private/governmental
            'Probably poorest countries have highest govt share

• '   Augment External Debt Data with Current Account Accummulation and Compute Global Balance
• If there is no data for CXDEBTRPA then use the cumulative sum calculated from current account above.
• Make sure that debt is at least as big as the sum of WB, IMF, and private debt calculated above.
• Make sure that assets are at least as big as WB donations IMF donations, and private assets.
• 'Assume debt data better than asset and impose on assets - Scale each lender countries assets to align with global debt
• '   Compute governmental external debt and government domestic debt - set  government debt (CXGOVTDEBT) to total debt (CXDEBTRPA) minus firm debt (CXFIRMDEBT). This assumes that there is no household external debt.

Flows

IFI

'   Read WB Net Flows and Estimate Outflows and Inflows
'       Must do after stocks because need CXWBLOANS

• Estimate using average of last 5 years of inflows. Balance inflows and outflows so that they match.
• The initialization of World Bank outflows (CXWBLNFOUT) requires World Bank loans (out) as a stock (CXWBLOANS). CXWBLNFOUT is initalized using the equation below, which also uses (sxwblnintr) and (sxwblnrepr).
  • Note: Unsure of exactlty what these global parameters (sxwblnintr and sxwblnrepr) are.

            CXWBLNFOUT(ICount%) = (CXWBLOANS(ICount%) * sxwblnintr / 100 _
                + CXWBLOANS(ICount%) / AMAX(1, sxwblnrepr))

'   Read IMF Net Flows and Estimate Outflows and Inflows
'       Must do after stocks because need CXIMFCREDIT

• Same as World Bank above - use the average of the past 5 years for inflows. Use the following equation for outflows, which requires outgoing stocks, initialized above.

            CXIMFCRFOUT(ICount%) = (CXIMFCREDIT(ICount%) * sximfcrintr / 100 _
                + CXIMFCREDIT(ICount%) / AMAX(1, sximfcrrepr))

Remittances

• Initialize outgoing remittances using SeriesXWorkerRemitPaid and incoming remittances using SeriesXWorkerRemitReceived. Normalize each country's paid and received using RemitNormReceived and RemitNormPaid, normalizing coefficient calculated elsewhere.
  • Note: I think this is normalize total paid and received i.e. total outflows for all countries and total inflows for all countries. The global balance below is to balance NET inflows and outflows.
