The U.S. crops model is one component of the integrated modeling system developed and maintained by the Food and Agricultural Policy Research Institute (FAPRI), which operates as a joint program at Iowa State University and the University of Missouri-Columbia. The FAPRI system is used to generate medium-term projections of the agricultural economy and to conduct policy analysis. The U.S. crops model determines domestic supply, utilization, and prices for wheat, corn, sorghum, oats, barley, soybeans, soybean meal, soybean oil, rice, and cotton, Other components of the FAPRI system include world trade models for grains and oilseeds, domestic livestock models, and satellite models that determine U.S. net farm income and the government cost of agricultural programs.
