United States Immigration Policy: The 1965 Act and its Consequences
研究了1965年美国移民法案如何导致移民总量激增和来源国从欧洲转向亚洲与拉丁美洲，发现家庭团聚效应是主因，且来源国越穷效应越大。
Abstract The United States Immigration Act of 1965 was followed by a steep upward trend in total immigration, and by a dramatic shift in the source‐country composition away from Europe and towards Asia and Latin America. In this paper I ask if and how the 1965 Act generated these unanticipated consequences. The result was partly because of the pre‐existing legislation and partly because of the admission of immigrants outside the terms of the Act. However, much of it was a result of the Act itself, and specifically because of family reunification effects that were larger, the poorer the source country.
