1. Balance the social accounting matrix using linear or nonlinear programming:

   gams tzabal gdx=tzabal

2. Map the social accounting data into labelled submatrices:

   gams tzamap gdx=tzamap

3. Formulate a model based on the source data, replicate the benchmark equilibrium and perform some policy experiments:

   gams tzamdl

Here are the three programs and the input data in a zip file.
