Immigrant Participation in the Welfare System
利用1970和1980年美国人口普查数据，分析移民参与福利体系的程度，发现近期移民群体比早期群体更依赖福利，且移民在美国居住越久越可能领取福利，这主要归因于移民来源国的变化。
This paper presents an empirical analysis of immigrant participation in the welfare system using the 1970 and 1980 U.S. Censuses. The availability of two cross-sections allows for identification of cohort and assimilation effects. The data indicate that recent immigrant cohorts use the welfare system more intensively than earlier cohorts. In addition, the longer an immigrant household has been in the United States, the more likely it is to receive welfare. The analysis also suggests that a single factor, the changing national origin mix of the immigrant flow, accounts for much of the increase in welfare participation rates across successive immigrant waves.
