The economic convergence of American regions has greatly slowed, and rates of long-term non-employment have even been diverging. Simultaneously, the rate of non-employment for working age men has nearly tripled over the last 50 years, generating a terrible social problem that is...

Using the mass closure of development zones in 2004 as a natural experiment, we examine the causal effect of development zones on firm level TFP in China. The difference-in-difference estimator shows that on average, loss of development zone policies results in 6.5% loss of firms' TFP....

We study optimal spatial policies in a quantitative trade and geography framework with spillovers and spatial sorting of heterogeneous workers. We characterize the spatial transfers that must hold in efficient allocations, as well as labor subsidies that can implement them. There exists scope...

Many studies of regional disparity in China have focused on the preferential policies received by the coastal provinces. We decomposed the location dummies in provincial growth regressions to obtain estimates of the effects of geography and policy on provincial growth rates in 1996-99. Their...

This paper makes two contributions to the literature on the determinants of international migration flows. First, we compile a new dataset on annual bilateral migration flows covering 15 OECD destination countries and 120 sending countries for the period 1980-2006. We also collect data on...

Starting from the same level of productivity and per-capita income as the United States in the mid-nineteenth century, Europe fell behind steadily to a level of barely half in 1950, and then began a rapid catch-up. While Europe's level of productivity has almost converged, its income per person...

Following the rationale for regional redistribution programs described in the official documents of the European Union, this paper studies a very simple multi-country model built around two regions: a core and a periphery. Technological spill-overs link firms' productivity in each of the two...

This paper documents the abnormally slow recovery in the labor market during the Great Recession, and analyzes how mortgage modification policies contributed to delayed recovery. By making modifications means-tested by reducing mortgage payments based on a borrower's current income, these...

The Great Recession from December 2007 to June 2009 is associated with a dramatic weakening of the labor market from which the labor market is now only slowly recovering. The unemployment rate remains stubbornly high and durations of unemployment are unprecedentedly long. I use data from the...

In response to the Great Recession, the availability of unemployment insurance (UI) benefits was extended to an unprecedented 99 weeks in many U.S. states in the 2009-2012 period. We use matched monthly data from the CPS to exploit variation in the timing and size of the UI benefit extensions...
