In Germany, the productivity of professional services, a sector dominated by micro and small firms, declined by 40 percent between 1995 and 2014. This productivity decline also holds true for professional services in other European countries. Using a German firm-level dataset of 700,000...

The division of labor between and within countries is driven by two fundamental forces, comparative advantage and increasing returns. We set up a simple Ricardian model with a Marshallian input sharing mechanism to study their interplay. The key insight that emerges is that the interaction...

The direct impact of local public goods on welfare is relatively easy to measure from land rents. However, the indirect effects on home and job location, on land use, and on agglomeration benefits are hard to pin down. We develop a spatial general equilibrium model for the valuation of these...

This paper explores the relationship between routine-biased technological change and agglomeration economies. Using administrative data from the Netherlands, we first show that in dense areas, jobs are less routine-task intensive (i.e. less repetitive and automatable), meaning that jobs cover a...

We examine effects of the COVID-19 pandemic on employment losses across metropolitan area status and population size. Non-metropolitan and metropolitan areas of all sizes experienced significant employment losses, but the impacts are much larger in large metropolitan areas. Employment losses...

This paper examines the role of regional aggregation in measuring agglomeration externalities. Using Dutch administrative data, we define local labour markets (LLMs) based on the worker's commuting outcomes, gender and educational attainment, and show that high-educated workers and male workers...

We develop a model in which ethnic minorities can either assimilate to the majority's norm or reject it by trading off higher productivity and wages with a greater social distance to their culture of origin. We show that "oppositional" ethnic minorities reside in more segregated areas, have...

This paper investigates the effects of services offshoring on wages using individual level data combined with industry information on offshoring. Our results show that services offshoring affects the real wage of low and medium skilled individuals negatively. By contrast, skilled workers benefit...

This paper presents a simple, analytically solvable Chamberlinian agglomeration model. As in the canonical core-periphery (CP) model, two agglomerative forces are at work. However, the present model exhibits a "pitchfork bifurcation" rather than the "tomahawk bifurcation" of the CP model.

This paper investigates the impact of labor markets and economies of agglomeration on firms location. We show that the existence of a lower bound on wage (e.g. a minimum wage or a reservation wage) introduces asymmetric location of firms. Moreover, changes in that lower bound or in global...
