MPSGE Models in GAMS

What is MPSGE?

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.

How does one learn about how to use MPSGE?

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:

• Introduction to MPSGE
• GAMS/MPSGE: The Modeling Framework and Syntax
• MPSGE Models in GAMS
• 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
