The Bartik instrument is formed by interacting local industry shares and national industry growth rates. We show that the typical use of a Bartik instrument assumes a pooled exposure research design, where the shares measure differential exposure to common shocks, and identification is based on...

In this chapter we analyze immigration and its effect on urban and regional economies focusing on productivity and labor markets. While immigration policies are typically national, the effects of international migrants are often more easily identified on local economies. The reason is that their...

Local labor market shocks are difficult to insure against. Using confidential micro data from the U.S. Census Bureau's Longitudinal Business Database, we document that firms redistribute the employment impacts of local demand shocks across regions through their internal networks of...

Using US Census data for 1990-2000, we estimate effects of NAFTA on US wages. We look for effects of the agreement by industry and by geography, measuring each industry's vulnerability to Mexican imports, and each locality's dependance on vulnerable industries. We find evidence of both effects,...

In light of the current economic crisis, we estimate hazard models of divorce to determine how state and national unemployment rates affect the likelihood of divorce. With 89,340 observations over the 1978-2006 period for 7633 couples from the 1979 NLSY, we find mixed evidence on whether...

We document the consequences of real exchange rate movements for the employment, hours, and hourly earnings of workers in manufacturing industries across individual states. Exchange rates have statistically significant wage and employment implications in these local labor markets. The importance...

Low-skill workers are comparatively immobile: when labor demand slumps in a city, low-skill workers are disproportionately likely to remain to face declining wages and employment. This paper estimates the extent to which (falling) housing prices and (rising) social transfers can account for this...

In this paper, I study the effect of economic integration with the United States on state-industry employment growth in Mexico. I disentangle the effects of two opposing forces on regional labor demand: transport-cost considerations, which, all else equal, encourage firms to relocate their...

This paper analyzes the effects of demand shifts within and between local labor markets on unemployment and employment levels and changes observed in those markets. Between-market demand shifts are measured by the means of sales growth for firms in each market, while within-market shifts are...

This paper documents, using county level data, some geographical features of the US business cycle over the past 30 years, with particular focus on the Great Recession. It shows that county level unemployment rates are spatially dispersed and spatially correlated, and documents how these...
