Abstract: This report documents the static world policy simulation (SWOPSIM) model building framework. The framework consists of computer programs which generate standard global partial equilibrium models in spreadsheets. SWOPSIM models are designed to simulate the effect of changes in producer and consumer support policies on production, consumption, and trade. Several types of world models can be constructed including single product models, multi-product net trade models, and Armington type bilateral trade flow models. Economic linkages across products within a country occur via cross price and "inputoutput" relationships. Linkages across countries and regions take place through domestic-international price linkage equations and world product trade. Topics covered include the economics of SWOPSIM models and the mechanics of the model building with the SWOPSIM framework. An extensive reference section lists source documents as well as published studies that have used the framework. The bulk of the documentation consists of detailed appendices which include annotated listings of variable definitions and model equations, a listing of a SWOPSIM demonstration model, screens of computer tutorials on SWOPSIM model building, printouts of the computer programs making up the SWOPSIM framework, and SWOPSIM installation instructions.
