The Market for Land and the Impact of Farm Programs on Farm Numbers
构建了一个不同能力的农民之间交易土地的模型，评估了四种农业计划对产出价格、土地价格和农民数量的影响，初步证据表明一些标准政策工具会减少农场数量。
Abstract If a land price is to be observed, there must be trades of land. If the aggregate quantity of land in agriculture is fixed, those trades must be among farmers. This paper presents a model in which farmers of differing “ability” trade land among themselves. The model is used to evaluate the impact of farm programs (a demand enhancement program; a price support program; a land retirement program; an income subsidy program) on output price, land price, and number of farmers. Effects of these programs depend on conditions that require empirical evaluation. Preliminary evidence suggests that some standard tools of farm policy have the effect of reducing farm numbers.
