Model Updates

• There have been two major sets of changes in the code (beyond various odds and ends):

1. Intersectoral flows from the ag model (namely INDEM, FMDEM, and FEDDEM) are now used to alter relevant cells in the GTAP-based IO matrix of the general equilibrium model, helping make the general model and ag model behave much more alike than they did before.
2. Improvements were made in the preprocessor to estimate values of remittances in and out for countries with data showing foreign born populations in or out but not having data on remittances.  In terms of sending countries, the UAE and Singapore are the big ones here.  In terms of recipient countries there were a handful with null remittance values.  To help do this I added 2 new cross-sectional functions to TablFunc.mdb.

• The major focal point of my work has continued to be the Total SAVINGS = I (IGCF plus delta stocks) identity, while paying attention simultaneously to the various more agent-based equilibration processes (especially government revenues and expenditures and countries with each other).  In my most recent Base case (checked for run-to-run) it now looks like this, hugely improved relative to earlier versions where the variation as % of GDP was running up toward +- 30%.   The big spike in 2022 is Ukraine with war-damaged GDP and the run up toward the end is Somalia for understandable reasons around foreign aid receipts.  The spikes in 2017 are mostly data complications.

• Fix on Govt Expenditures initialization
• Address issues like Sudan moving from initial intl debt to hibh assets because of huge XS in services growth.
• Fixes to Growth Migration

Data Updates

• Updated 6 migrant related tables. Their historical values are now available, collected from IFs7.82.
• Deleted those 0s from Somalia’s remittances inflow.
• Added values for UAE’s remittances outflow.
