Farms, farm households, and productivity of resource use in agriculture
构建了一个家庭农场模型，分析资源由农户供给而农场在竞争中使用，并讨论不完全市场对收入和生产率的含义，对农业政策有启示。
Farms are seen and analyzed by contemporary agricultural economics as firms producing farm products only. Although most farms in western countries are managed by farm families, the economics and economic implications of family farms as the dominant institution in agriculture are neglected almost totally. In the article, first, a simple model of family farms is developed where resources available are supplied by the farm household whereas the farm is demanding such resouces, however, in competition with efficient resource use outside that farm. Modifications of the micro-theory of the family farms due to imperfect instead of perfect labor and land markets are presented as well. Next, implications of the farm as a correlate of the farm household for income and productivity of resource use in agriculture are discussed. Finally, further consequences with respect to agricultural policy are mentioned. Copyright 1989 by Oxford University Press.
