This paper analyzes the evolution of wage inequality and wage mobility separately for men and women in West and East Germany over the last four decades. Using a large administrative data set which covers the years 1975 to 2008, I find that wage inequality increased and wage mobility decreased...

Diese Arbeit untersucht empirisch den Zusammenhang von Beschäftigung und Lohnstrukturen zwischen sowie innerhalb von Qualifikations- und Altersgruppen. Zunächst werden Substitutionselastizitäten zwischen Qualifikations- und Altersgruppen geschätzt und die Lohnveränderungen bestimmt, die...

R&D collaboration facilitates pooling of complementary skills, learning from the partner as well as sharing risks and costs. Research therefore repeatedly stressed the positive relationship between collaborative R&D and innovation performance. Fewer studies addressed potential drawbacks of...

The shift of employment from lower to higher productive firms is an important driver for structural change and industry dynamics. We investigate this reallocation in terms of employment gains and losses from innovation. New employment created by product innovation may be offset by employment...

The Mannheim Enterprise Panel (Mannheimer Unternehmenspanel – MUP) of the Centre for European Economic Research (ZEW) is the most comprehensive micro database of companies in Germany outside the official business register (which is not accessible to the public). The MUP is based on the firm...

This study revisits the increase in wage inequality in Germany. Accounting for changes in various sets of observables, composition changes explain a large part of the increase in wage inequality among full-time workers. The composition effects are larger for females than for males, and...

This paper explores the role of R&D worker mobility on innovation performance. As one main novelty, we employ churning as a measure for worker mobility. Churning depicts the number of workers which are replaced by new ones. It is a very informative indicator since a firm may be exposed to...

In this article we study differences in the returns to R&D investment between firms that sell in international markets and firms that only sell in the domestic market. We use German firm-level data from the high-tech manufacturing sector to estimate a dynamic structural model of a firm's...

This article investigates how a firm's financial strength affcts its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German firms in high-tech manufacturing industries. The model incorporates a measure of the firm's financial strength, derived from its...
