Who Leaves? The Outmigration of the Foreign-Born
分析美国外国出生者的回迁现象，认为回迁可能是生命周期居住地序列的一部分，或因初始移民决策信息有误。利用1980年人口普查和移民局数据，发现移民倾向于返回离美国不远且富裕的国家，且回迁加剧了留美移民的选择性特征。
This paper analyzes the return migration of foreign-born persons in the United States.We argue that return migration may have been planned as part of an optimal life cycle residential location sequence.Return migration also occurs because immigrants based their initial migration decision on erroneous information about opportunities in the United States.The study uses the 1980 Census and administrative data from the immigration and Naturalization Service.Immigrants tend to return to wealthy countries which are not too far from the United States.Moreover, return migration accentuates the type of selection characterizing the immigrant population left in the United States.
