Turnover in U.S. Agricultural Labor Markets
研究发现美国农业工人频繁进出农业，职业转换时间短；合法女性工人离职后更久不工作，且非农就业机会少于男性；1986年移民改革与控制法案的大赦并未如预期导致多数人离开农业。
Abstract Agricultural workers move in and out of agriculture frequently. Migration between types of jobs takes relatively little time. Legal female workers tend to stay out of the U.S. labor market longer once they stop being employed and their access to jobs outside of agriculture is more limited than that of their male counterparts. Predictions made when the 1986 Immigration Reform and Control Act was passed that granting people amnesty would induce most of them to leave agriculture were incorrect.
