英文文献摘要：
Despite of the important role international migration fills in the United States’ labor-intensive agricultural sector, few studies have addressed the individual characteristics and circumstances surrounding entry and exit by farm laborers. With increasing public attention on international migrant labor, policymakers have a need to understand the labor market patterns of these workers if they are to formulate appropriate immigration reforms, including temporary worker programs geared towards agriculture. In this analysis, we model the likelihood of entering agricultural employment by migrants to the United States. Using data from the Mexican Migration Project we find that migrants with higher levels of education and a greater command of English are less likely to work as agricultural laborers. Those that do enter agricultural occupation stay in the United States for shorter periods of time per trip than those who enter non-agricultural occupation. In future analysis we will attempt to model the demand for agricultural farm work as a determinant of the decision by migrants to enter the U.S. market for hired farm labor.

尽管国际移民在美国劳动密集型的农业部门中扮演着重要的角色，但很少有研究探讨农场劳动力进入和离开的个体特征和环境。随着公众对国际移民劳工的关注日益增加，政策制定者如果要制定适当的移民改革，包括针对农业的临时工人计划，就需要了解这些工人的劳动力市场模式。在这个分析中，我们建立了移民进入美国农业就业的可能性模型。根据墨西哥移民项目的数据，我们发现，教育水平较高和英语水平较高的移民不太可能从事农业工作。那些从事农业工作的人每次在美国停留的时间比从事非农业工作的人要短。在未来的分析中，我们将尝试模拟农业工作的需求，作为移民决定进入美国市场雇佣农场劳动力的一个决定因素。
