Worker Turnover, Farm Labor Contractors, and IRCA's Impact on the California Farm Labor Market
通过计量分析农场工人流动率，检验1986年移民改革与控制法案是否减少了加州农业对新移民的依赖，结果不支持该法案初期有效的假设。
Abstract Employer sanctions under the 1986 Immigration Reform and Control Act (IRCA) were intended to encourage U.S. employers to adjust to a smaller, more legal workforce. This paper presents findings of an econometric analysis of farm worker turnover as a vehicle to test IRCA's effectiveness. Our findings do not support the hypothesis that IRCA initially succeeded in reducing the reliance on new immigrants in California agriculture.
