Extract: This report presents a grain, oilseeds, and livestock modl of Japan (JPGOL). It describes the background, product coverage, and model structure of JPGOL. A computer-generated listing of the model is provided. The model includes equations for food demand, feed demand, crop and livestock supplies, stocks trade, and supply and demand prices. The model takes into account cross-community effects on both the demand and supply sides of Japan's grain, oilseeds, and livestock complex. The report also discusses the policy analysis capabilities of the model and presents some results of model simulation.

Extract: Japanese grain yields, areas, production, food demand, feed demand, trade, and government pricing policies are modeled on the basis of data mostly from 1965-79. Grains are classified into rice, wheat, corn, and other coarse grains, with the last often subdivided into barley and other grain. The model is then simulated through 1992, using as exogenous variables projections of Japanese population, Japanese real income, and U.S. grain prices (as proxies for world trade prices). The model's equations are designed for making 5- to 20- year projections, but alternative equations more suited to short-run policy analysis are also presented.
