摘要：A multicommodity, multiregional linear programming model is employed to obtain price differentials between 16 U.S. regions for corn, barley, grain sorghum, and oats. The price differentials are used to obtain loan support rates (for the 1974 crop) in each region, for each grain, so that relative feeding values, transport rates, and supply and demand conditions are an integral part of the loan rate structure.
