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...

How integrated are labor markets within a country? Labor mobility is key to the integration of local labor markets and therefore to understanding the efficacy of policies to reduce regional inequality. We present a comprehensive framework for understanding migration decisions, focusing on the...

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...

We explore the links between social capital and labor market networks at the neighborhood level. We harness rich data taken from multiple sources, including matched employer-employee data with which we measure the strength of labor market networks, data on behavior such as voting patterns that...

Fifteen years after German reunification, the facts about slow regional convergence have born out the prediction of Barro (1991), except that migration out of East Germany has not slowed down. I document that in particular the 18-29 year old are leaving East Germany, and that the emigration has...

This paper uses 1990 Census data to study the effects of immigrant inflows on the labor market opportunities of natives and older immigrants. I divide new immigrants, older immigrants, and natives into distinct skill groups and focus on skill-group-specific outcomes within cities. An important...

This paper offers an analysis of cyclical and secular patterns in job turnover using establishment-level data. We provide evidence from multiple data sets that show that the job turnover process is markedly different over time and across regions. Over time, we find that employment fluctuations...

We examine labor market integration in east and southeast Asia (ESEA) during the 1980s, focusing on intraregional labor mobility and on the two other main channels of integration: capital mobility and trade. We find evidence that labor market integration increased sharply among ESEA countries in...
