REGULATORY POLICY PROGRAMThe Regulatory Policy Program at the Mossavar-Rahmani Center for Business and Government serves as a catalyst and clearinghouse for the study of regulation across Harvard University. The program's objectives are to cross-pollinate research, spark new lines of inquiry, and increase the connection between theory and practice. Through seminars and symposia, working papers, and new media, RPP explores themes that cut across regulation in its various domains: market failures and the public policy case for government regulation; the efficacy and efficiency of various regulatory instruments; and the most effective ways to foster transparent and participatory regulatory processes.The views expressed in this paper are those of the authors and do not imply endorsement by the Regulatory Policy Program, the Mossavar-Rahmani Center for Business and Government, Harvard Kennedy School, or Harvard University.

AbstractThe past thirty years have seen a dramatic decrease in the rate of income convergence across U.S. states. This decline coincides with a similarly substantial decrease in population flows to wealthy states. We develop a model where labor mobility plays a central role in convergence and can quantitatively account for its disappearance. We then link this decline in directional migration to a large increase in housing prices and housing regulation in high-income areas. The model predicts that these housing market changes generate (1) a divergence in the skill-specific economic returns to living in rich places, (2) a decline in low-skilled migration to rich places and continued low-skilled migration to places with high income net of housing costs, (3) a decline in the rate of human capital convergence and (4) continued income convergence among places with unconstrained housing supply. Using Census data, we find support for the first three hypotheses. To test the fourth hypothesis, we develop a new state-level panel measure of housing supply regulations. Using this measure as an instrument for housing prices, we document the central role of housing prices and building restrictions in the end of income convergence.JEL Codes: E24, J23, J24, R14, R23, R52
