Sectoral Implications of Farm Program Modifications
用数学规划部门模型分析农业计划及其修订对生产、消费、价格和福利的影响，发现当前计划导致超额生产和社会净损失，削减计划对社会整体有利。
Abstract The overall and distributional effects of farm programs and selected revisions are examined using a mathematical programming sector model. The model incorporates market distortions caused by price supports, target prices, program participation, deficiency payments and marketing loans. Current farm programs are found to increase producer prices, depress consumer prices, and in turn result in excess production and higher consumption and exports. Domestic and foreign consumers as well as domestic producers are subsidized by farm programs. Social deadweight loss occurs as government payments exceed welfare benefits received by consumers and producers. Society as a whole benefits from reductions in program provisions.
