The aim of the SplitCom project is to develop a set of programs to facilitate the addition of sectors to a standard GTAP database. For example, one might wish to split GTAP's mvh (motor vehicles and parts) sector into three: "Cars", "OtherMV" and "MVparts".

Mark Horridge completed initial versions of these programs at end 2005; development continues (slowly).

Three groups kindly agreed to sponsor the project, namely:

This web-page allows sponsors or other interested parties to download current versions of SplitCom programs.


Initial version [Nov 2005][minor updates Feb 2007, Jan 2008, Oct 2008]

Download splitcom.zip (14.7 Mb) and unzip into an empty new folder with a short and simple name (such as C:\SplitCom). Print out and study the file SplitCom.Doc before experimenting with the programs.

Short form of initial version [Nov 2005][minor updates Feb 2007, Jan 2008, Oct 2008]

Only of use to those with a slow internet connection and a source code installation of GEMPACK 9 or later. Unzip splitsht.zip (1.52 Mb) into an empty new folder (eg, C:\SplitCom). Then run script CompAllF.bat to generate necessary EXE/AXS/AXT files.
