Technological progress and trade potentially affect wages and employment. Technological progress can make jobs obsolete and trade can increase unemployment in import competing sectors. Empirical evidence suggests that both causes are important to explain recent labour market developments in many...

The availability and composition of labor is fundamental for the structure of international trade. This points towards the importance of demographic transitions that affect trade through, for example, changing capital-labor ratios, urbanization dynamics, or changes in the composition of demand...

In explaining the uneven spatial distribution of economic activity, urban economics and new economic geography (NEG) dominate recent research in economics. A main difference between these two approaches is that NEG stresses the role of spatial linkages whereas urban economics does not do so. We...

We construct a unique data set to analyze whether or not a large temporary shock had an impact on German city growth and city size distribution. Following recent work by Davis and Weinstein (2001) on Japan, we take the strategic bombing of German cities during WWII as our example of such a...

The literature on China indicates that the concentration of economic activities in China is less than in other industrialized countries. Institutional limits are largely held responsible for this finding (e.g. the Hukou system); firms and workers are not able to take full advantage of the...
