Agrarian Structure and Agricultural Practice: Typology and Application to Western Sudan
构建了一个解释农场禀赋、实践与产量差异的类型学模型，发现租地不安全、融资约束和保险缺失会导致财富与产量正相关，并用西苏丹村庄数据验证了这一现象。
Abstract A typology of models that explain patterns of variation in farm endowments and farm practices and yields shows that insecurity in renting land, financing constraints, and the absence of insurance generate patterns of factor use quite different from the famous “inverse relationship” caused by labor supervision problems. One might expect to observe positive relationships between wealth and yields. Village‐level data from western Sudan confirm that such positive relationships are not a theoretical curiosity. Wealthy farmers have higher levels of output per hectare because they use more labor per hectare. Insurance and financing constraints appear to be the crucial market failures.
