Labor for the Picking: the New Deal in the South
研究了1930年代大萧条期间美国南方地主用雇佣劳动和机械替代分成佃农和骡子的现象，证据表明新政的农业调整政策通过提高土地资产价值而未保障佃农权益，并放松了此前阻碍机械化的收获劳动约束，导致了佃农的流失。
During the Great Depression of the 1930s southern landlords began to replace sharetenants and mules with wage laborers and large-scale preharvest machinery. Informed observers in the 1920s did not expect this to happen until the advent of the mechanical cotton picker, which came after World War I. This paper presents evidence supporting the claim that the AAA policies of the 1930s, and the economic depression they were designed to cure, induced this tenant displacement by increasing the asset value of land rights without securing tenants a share right, and by relaxing the harvest labor constraint that had previously impeded mechanization.
