In this paper we show that the recent model by Duranton (AER, 2007) performs remarkably well in replicating the city size distribution of West Germany, much better than the simple rank-size rule known as Zipf's law. The main mechanism of this theoretical framework is the churning of industries...

During the last decade there have been marked changes in the composition of the non-native workforce in the German labour market. In particular there has been a notable increase in the diversity of nationalities of which the foreign workforce is composed. In this paper we investigate the effects...

The salient rank-size rule known as Zipf's law is not only satisfied for Germany's national urban hierarchy, but also for the city size distributions in single German regions. To analyze this phenomenon, we build on the insights by Gabaix (1999) that Zipf's law follows from a stochastic growth...

We analyze the first data set on consistently defined functional urban areas in Europe and compare the European to the US urban system. City sizes in Europe do not follow a power law: the largest cities are ?too small? to follow Zipf?s law.

This paper addresses the impact of rising international trade exposure on individual earnings profiles in heterogeneous worker-establishment matches. We exploit rich panel data on job biographies of manufacturing workers in Germany, and apply a high-dimensional fixed effects approach to analyze...

Regional unemployment rates in the European Union (EU-15) reveal a core-periphery structure. Large ?core? regions in the middle of the continent have low unemployment rates, whereas excessive mass unemployment is predominantly found in the peripheral regions at the outside borders of EU-15. This...

We address the effects of wages on employment growth on the basis of a theoretical model from which cost and demand effects can be derived. In the empirical analysis we take a highly disaggregated perspective and apply a newly developed shift-share regression technique on an exhaustive and very...

In this paper we describe the development of regional specialisation and geographical concentration in Germany between 1993 and 2001. Somewhat contrary to theoretical expectations derived from the recent literature in location theory, we neither find compelling evidence for a specialisation...

A very prominent instrument of regional policy is to foster education and human capital for-mation in economically lagging regions. However, this type of regional policy might actually hurt instead of help the recipient areas. The reason is that individual geographical mobility increases with...

Using comprehensive data for German establishments, we estimate plant-evel production functions to analyze if cultural diversity affects total factor productivity. We distinguish diversity in the establishment's workforce and in the aggregate labor force of the region where the plant is located....
