Innovation activities in the German enterprise sector showed two opposing trends over the past two decades: While total innovation expenditures grew substantially, the number of firms conducting innovation activities fell sharply.

In this paper we analyze the conditions under which firms decide to offshore innovation.

Using unique data from the German...

This paper investigates the impact of energy policies on the export performance of firms. There has been a long policy debate on potentially negative impacts of cost-increasing energy policies on international competitiveness. We use firm-level data from three countries with similar industry...

Distinguishing carefully between mobility across firms and across occupations, this study provides causal estimates of the wage effects of mobility among graduates from apprenticeship in Germany. Our instrumental variables approach exploits variation in regional labor market characteristics....
