Effect of U.S. Immigration Reform on Labor‐Intensive Agricultural Commodities
分析1986年移民改革法案对季节性农业劳动力供给的影响，发现劳动力份额和产出需求弹性是关键因素，若当前需求条件持续，适度劳动力减少对生产影响较小。
Abstract A major concern in development of the 1986 Immigration Reform and Control Act was the potential for reductions in seasonal farm labor supply. Although the act appears to have increased farm labor supply, future immigration policy will likely be affected by similar concerns. Muth's model of industry supply and factor demand is adapted to analyze effects of labor supply reductions on selected U.S. crops. Labor factor share and output demand elasticity are the most important factors influencing the impact of labor supply on production, and effects of moderate supply decreases will be small if recent output demand conditions continue.
