摘要

US social transfer programs vary substantially across states, incentivizing households to locate in states with more generous transfer programs. Furthermore, transfer formulas often decrease in income, thereby rewarding low-income households for living in low-paying cities. We quantify these distortions by combining a spatial equilibrium model with a detailed model of transfer programs in the United States. The current system leads to locational inefficiency of 4.88% of total transfer spending. A reform that both harmonizes transfer policies across states and indexes household income to local average earnings reduces this inefficiency by more than 60% while preserving the programs' means-tested nature.
