Introduction to GEMPACK for GAMS Users

This document introduces GEMPACK to readers who are familiar with using GAMS for general equilibrium modeling. The document points out similarities and differences between GAMS and GEMPACK. The many similarities make it relatively easy for a GAMS modeler to begin using GEMPACK productively. A very basic general equilibrium model is used to illustrate the similarities and differences. Readers wishing to obtain hands-on experience with GEMPACK can find detailed instructions for running this model in GEMPACK using the free Demonstration Version. Both the model and the GEMPACK software can be downloaded from the web.
