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.
