MPSGE

What is MPSGE?

MPSGE is a high level language for creating computable general equilibrium (CGE) models. Originally implemented in FORTRAN and made available as a subsystem in GAMS. The MPSGE documentation provided by GAMS is a useful reference, especially for background, theory, and some understanding of the included features.

Resources for getting started

JuMP

PATH Solver
For models with more than 300 variables or 2000 nonzeros, a PATH license needs to be set up on the system/computer. Otherwise the solve will throw an error:

  • Solver Status: OTHER_ERROR
  • Model Status: UNKNOWNRESULTSTATUS.

The link above has instructions for installing a free license for academic use.

How the documentation is structured

Note

This documentation is under active development.

  • Tutorials: Written for new users of MPSGE. Walks through the MPSGE modelling process step-by-step.
  • Mathematical Background: MPSGE hides most of it's computation, this page describes precisely how MPSGE works.
  • API Reference: A complete list of the functions MPSGE makes available. This is the same information you get in the help entry for individual functions.

Citing MPSGE

A paper is being prepared. In the meantime reach out to the authors of the package for information.
