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.

We study the impact of trade exposure in the job biographies, measured with daily accuracy, of 2.4 million workers in Germany. To profit from export opportunities, workers adjust through increased employer switching. Highly skilled workers benefit the most, consistent with an increase in skill...

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 effects of the unprecedented rise in trade between Germany and "the East" - China and Eastern Europe - in the period 1988-2008 on German local labor markets. Using detailed administrative data, we exploit the cross-regional variation in initial industry structures and use trade...

In this paper we show that the double Pareto lognormal (DPLN) parameterization provides an excellent fit to the overall US city size distribution, regardless of whether "cities" are administratively defined Census places or economically defined area clusters. We then consider an economic model...

We analyze how globalization has affected the sectoral anatomy of regional growth in Germany over the period 1978-2008. The aggregate German economy is characterized by a secular decline of manufacturing and a rise of modern service industries. This trend - also known as Petty's law - is not...

In this paper I analyze the impact of human capital on local employment growth for the case of West Germany (1977-2002). I find robust evidence that skilled cities grow faster than unskilled ones, but this need not indicate localized human capital externalities are at work. A large initial share...

In this paper we study the dynamics of local employment growth in West Germany from 1980 to 2001. Using dynamic panel techniques, we analyse the timing of the impact of diversity and specialisation, as well as of the human capital structure of local industries. Diversity has a positive effect on...

The German economy exhibits rising service and declining manufacturing employment. But this decline is much sharper in import-competing than in export-oriented branches. We first document the individual-level job transitions behind those trends. They are not driven by manufacturing workers who...

We introduce a simple oligopolistic trade model with international transportation costs, and analyze the profitability and the social desirability of national vs. international mergers in relation to three different issues, (i) the level of trade freeness, (ii) the possibility of rent...
