Migratory Labor and Agriculture
发现农场工人对季节性迁移工作的经济激励反应强烈，通过经济模型区分迁移与非迁移工作的收入结构，并利用自选择调整的实证模型验证了比较优势理论，为移民和就业培训政策提供参考。
Abstract Farm workers are shown to respond strongly to economic incentives to seasonally migrate for work. The economic model is specified with separate earnings structures for migratory and nonmigratory work, and a reservation wage for migration is specified to reflect the choice between migratory and nonmigratory work. The empirical model adjusts for self‐selectivity in the sample and demonstrates that domestic farm workers sort themselves into migratory and nonmigratory workers in a manner consistent with the theory of comparative advantage. Implications for immigration and government employment and training programs are considered.
