Abstract

This paper describes the structure of PHILGEM, a single country computable general equilibrium (CGE) model of the Philippine economy. PHILGEM offers a good starting point for model development, especially for researchers who may want to extend their ORANI-G models to draw on supplementary data coming from a social accounting matrix (SAM). A generic version of the model is described here designed for expository purposes and for adaptation to other countries. The description of PHILGEM's equations and database is closely integrated with an explanation of how the model is solved using the GEMPACK system. Computer files are freely available, which contain a complete model specification and database.
