Supply Chain Model

This version includes the ImpactECON Supply Chain Model that is based on the ImpactECON supply chain database.

The version comes with a batch file (SCaux.bat) that converts a standard RunGTAP application and aggregation into a
Supply chain application and database.  Simply copy the contents of the Supply chain application zip file into a 
RunGTAP directory, copy your GTAP data aggregation into the same directory and then run the batch file from a DOS 
prompt. The use of a DOS prompt is recommended since it will indicate if the batch job has run successfully.  

Once run open the version in RunGTAP using Version | change and selecting the name of the directory containing your 
application.  Check Version | modules to ensure that the application is using the version specific settings for the 
main model, shocks, GTAPView, GTAPVol and Welfare decomp. PEELAST and GEElast should be turned off.  The standard 
Altertax version will work with this model.

For differences between the supply chain model and the standrad GTAP model search "IESCModel" in the tab code.  The model 
and data are documented in:
