  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.
