Immigration and Welfare Magnets
研究美国各州福利待遇差异是否影响移民的定居选择，发现领取福利的移民更集中在高福利州，且移民的福利参与率对福利水平变化比本地人更敏感。
This article investigates if the location choices made by immigrants when they arrive in the United States are influenced by the interstate dispersion in welfare benefits. Income-maximizing behavior implies that foreign-born welfare recipients, unlike their native-born counterparts, may be clustered in the states that offer the highest benefits. The empirical analysis indicates that immigrant welfare recipients are indeed more heavily clustered in high-benefit states than the immigrants who do not receive welfare, or than natives. As a result, the welfare participation rate of immigrants is much more sensitive to changes in welfare benefits than that of natives. Copyright 1999 by University of Chicago Press.
