We describe an unsupervised method for delineating functional labour market areas (LMAs) in national commuting networks. Our method uses the Louvain algorithm, which we extend to support top-down hierarchical LMA classification and estimable classification stabilities. We demonstrate our method...

Social mobility—the extent to which social and economic position in adulthood is facilitated or constrained by family origins—has taken an increasingly prominent role in public and policy discourse. Recent studies have documented that not only who your parents are, but also where you grow...

The East-West gap in the German population is believed to originate from migrants escaping the socialist regime in the German Democratic Republic (GDR). We use newly collected regional data and the combination of a regression discontinuity design in space with a difference-in-differences...

This review is framed around the exploration of a central hypothesis: A shift in public investment towards secondary towns from big cities will improve poverty reduction performance. Of course the hypothesis raises many questions. What exactly is the dichotomy of secondary towns versus big...

We analyze the role of optimal income taxation across different local labor markets. Should labor in large cities be taxed differently than in small cities? We find that a planner who needs to raise revenue and is constrained by free mobility of labor across cities does not choose equal taxes...

This paper examines the effects of foreign- and native-born STEM graduates and non-STEM graduates on patent intensity in U.S. metropolitan areas. I find that both native and foreign-born STEM graduates significantly increase metropolitan area patent intensity, but college graduates in non-STEM...

This paper studies the persistence of a large, unexpected, and regionally very unevenly distributed population shock, the inflow of eight million ethnic Germans from Eastern Europe to West Germany after World War II. Using detailed census data from 1939 to 1970, we show that the shock had a...

As a consequence of World War II, Austria was divided into four different occupation zones for 10 years. Before tight travel restrictions came into place, about 11 percent of the population residing in the Soviet zone moved across the demarcation line. We exploit this large internal migration...

This paper uses data on very small UK geographies to investigate the effective size of local labor markets. Our approach treats geographic space as continuous, as opposed to a collection of non-overlapping administrative units, thus avoiding problems of mismeasurement of local labor markets...

This paper provides descriptive evidence about the distribution of wages and skills in denser and less dense employment areas in France. We confirm that on average, workers in denser areas are more skilled. There is also strong over-representation of workers with particularly high and low skills...
