MPSGE is a *mathematical programming system
for general equilibrium analysis* which operates as a
subsystem within GAMS. MPSGE is
essentially a library of function and Jacobian evaluation
routines which facilitates the formulation and analysis of AGE
models. MPSGE simplifies the modeling process and
makes AGE modeling accessible to any economist who is interested
in the application of these models. In addition to solving
specific modeling problems, the system serves a didactic role as
a structured framework in which to think about general
equilibrium systems.

There does not exist a comprehensive users guide/manual for the software at this point in time, however there are a number of papers which describe the software or its applications. Here are some of the resources provided on this web site:

- GAMS/MPSGE: The Modeling Framework and Syntax
- An Introduction to Demand Theory through MPSGE
- A Library of Small Examples for Self-Study
- CES Functions: Some Hints and Useful Formulae
- Comparing the Performance of Flexible Functional Forms
- General Equilibrium with Public Goods
- Kevin O'Rourke: CGE and Economic History
- Linking Implan Social Accounts to MPSGE
- A partial list of publications based on MPSGE

Web pages which I plan to write at some point include:

- Modeling Small Open Economies
- Static Multiregional Models
- MPSGE Models of Environmental Tax Reform
- MPSGE Models with IRTS and Imperfect Competition
- How to Implement Intertemporal Models with GAMS/MPSGE
- Building MPSGE Models with GTAP Data
