High-skilled workers and high-productivity firms co-locate in large cities. In this paper, I study how the two-sided sorting of workers and firms affects spatial earnings inequality, efficiency of the allocation of workers and firms across cities, and the welfare consequences of place-based...

Previous research finds that the greater geographic mobility of foreign than native-born workers facilitates labor market adjustment to shifting regional economic conditions. We examine immigration's role in enabling U.S. commuting zones to respond to manufacturing job loss caused by import...

In the us, test score gaps by socioeconomic status and race increase with city size. This paper examines to what extent residential sorting on school quality can explain this fact. We combine 15 years of data on public elementary school students in North Carolina with geocoded school locations...

We examine the residential segregation of workers and the unemployed in the 80 largest cities in Germany. Drawing on a large set of geo-referenced data for the period from 2000 until 2015, we are able to study the within-city distribution of unemployment in unprecedented detail. We document a...

Despite worldwide expansion of higher education, the impact of higher education institutions on local economic activity is still poorly understood. We analyze the local economic effects of branch campus openings in Tennessee and Texas, two states representative of the underlying U.S. enrollment...

We examine "agglomeration shadows" that emerge around large cities, which discourage some economic activities in nearby areas. Identifying agglomeration shadows is complicated, however, by endogenous city formation and "wave interference" that we show in simulations. We use the locations of...
