Illegal Immigration and Immigration Control
分析了1986年美国移民改革与控制法案的经济逻辑，指出其大赦和雇主制裁措施未能解决非法移民问题，对研究移民政策的经济学者有参考价值。
The Immigration Reform and Control Act (IRCA) was passed in the closing days of the 1986 legislative session. The primary purpose of IRCA is to remove illegal aliens from the U.S. labor market. It has two primary policy instruments. One is granting legal status or amnesty for certain illegal aliens, thereby in part “wiping the slate clean.” The other is imposing penalties, referred to as employer sanctions, against employers who “knowingly” hire illegal aliens. Employer sanctions are intended to reduce the demand for illegal alien labor. The first sections of this paper develop an economic analysis of the illegal alien labor market, including the determinants of illegal migration and the impact on the economy. Then, that model is applied to the major provisions of IRCA and used to describe its likely consequences. A concluding section argues that because IRCA does not address the economic realities it is not likely to accomplish its objectives. The partial amnesty and impotent employer sanctions have not solved the illegal alien dilemma.
