Welfare-induced migration at state borders: New evidence from micro-data

This paper extends and synthesizes the various approaches used in the recent welfare migration literature to both offer the most comprehensive set of tests to date for welfare migration and to also determine the relative importance of short-distance moves in welfare migration flows. The current study follows on the finding of McKinnish [McKinnish T. Importing the poor: welfare magnetism and cross-border welfare migration. Journal of Human Resources 2005-40; 57-76.] of welfare migration effects obtained by comparing welfare participation at state borders to state interiors. This identification strategy is extended to micro-data from the 1980 and 1990 Decennial Censuses and combined with the demographic comparisons used elsewhere in the welfare migration literature. The signs and patterns of the estimates are consistent with the presence of welfare migration effects, and the magnitudes of the estimates are consistent with the importance of short-distance moves in welfare-induced migration flows, but most of the estimates are not statistically significant.
