The World Sugar Policy Simulation Model is a dynamic, partial equilibrium, net trade model. It distinguishes 18 countries and regions, and sugar is assumed to be a homogenous commodity. The model is designed for evaluating the effects on the world sugar economy of farm and trade policies by simulating production, consumption, stocks, and trade for sugar over a 10- to 15-year period.
