Welfare reform and interstate migration of poor families.

The thesis of this study is that as a result of increased inequalities in welfare rules, the 1996 welfare reform act not only enhanced incentives for poor families to move but also (and perhaps more important) created disincentives for them to stay in "race to the bottom" states. In testing this thesis, we evaluated the mediating and moderating roles of state economic development and family structure. We merged data from three main sources: the 1996-1999 panel of the Survey of Income and Program Participation, the Urban Institute's Welfare Rules Database, and state economic data from the Bureau of Labor Statistics.
