Mobility and Redistribution
分析联邦体系中地方政府在居民自由流动条件下的再分配政策，发现地方再分配会导致人口分类聚集。
The ability of individuals to move freely from one jurisdiction to another is generally seen as a constraint on the amount of redistribution that each jurisdiction within a system of governments can undertake. In this paper, the authors look at this proposition by developing a positive analysis of income redistribution by local governments in a federal system. They ask how much redistribution occurs when only local government can have tax/transfer instruments, individuals can move freely among jurisdictions, and voters in each jurisdiction are fully aware of the migration effects of redistributive policies. Local redistribution is shown to induce sorting of the population. Copyright 1991 by University of Chicago Press.
