This paper studies the relationship between wages and the degree of firm heterogeneity in a given industry under different wage setting structures. To derive testable hypotheses, we set up a theoretical model that analyses the sensitivity of wages to the variability in productivity conditions in...

Using unique recently released nationally representative high-quality longitudinal data at the enterprise level for Germany, this paper presents the first comprehensive evidence on the relationship between exports and profitability. It documents that the positive profitability differential of...

This paper investigates the impact of in-house R&D and innovation management practices on innovation success in small and medium-sized firms (SMEs). While there is little doubt about the significance of technology competence for generating successful innovations, inhouse R&D activities may be a...

This paper analyses whether wages in Germany respond to firm-specific profitability conditions. Particular emphasis lies on the question of whether the extent of rent-sharing varies across different systems of wage determination. Those may be categorised into sector-specific wage agreements,...

Determinants of a firm's export-sales ratio (degree of internationalisation) are frequently discussed in the literature related to individual firms' export activities. Stylised facts show a positive relationship between firm size and firm age on the one hand and the firm's export-sales ratio on...

The relationship between individual firms’ export behaviour and firm performance has been studied extensively in the economic literature. However, most studies from the field of economics only distinguish between exporting and non-exporting companies, using the firms’ export status as a...

So far, there has been no data set which observes firm formations in Germany not only on a cross-sectional basis using one-time surveys, but continuously over a number of years. Therefore, the Centre for European Economic Research (ZEW), KfW Bankengruppe and Creditreform set up a panel study of...

Energy and resource efficiency innovations (EREIs) are often seen as win-win opportunities for both the economic and the environmental performance of firms. It is thus worth asking how the innovation activities and performance of firms with regard to energy and resource efficiency look like: Do...

Using a large linked employer-employee data set, this paper studies the extent to which employers insure workers against transitory and permanent firm-level shocks. Particular emphasis is given to the question of whether the amount of wage insurance depends on the nature of industrial relations....

A recent survey of 54 micro-econometric studies reveals that exporting firms are more productive than non-exporters. On the other hand, previous empirical studies show that exporting does not necessarily improve productivity. One possible reason for this result is that most previous studies are...
