The aim of this paper is to analyse the effects of knowledge management on the innovation success of firms in Germany. Using a matching procedure on data from the German Innovation Survey of 2003 (Mannheim Innovation Panel), we pair firms applying knowledge management with twin firms with...

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

It is known that small firms rely mainly on the CEO's individual knowledge for developing innovations. Recent work suggests that this approach is inefficient since it underutilizes other employees' knowledge. We study to which extent using CEOs, managers and non-managerial employees' ideas...

Do contributions to online content platforms induce a feedback loop of ever more user-generated content or will they discourage future contributions? To assess this, we use a randomized field experiment which added content to some pages in Wikipedia while leaving similar pages unchanged. We find...

Are there positive or negative externalities in knowledge production? We analyze whether current contributions to knowledge production increase or decrease the future growth of knowledge. To assess this, we use a randomized field experiment that added content to some pages in Wikipedia while...

Existing data sets on firm formations in Germany suffer from various shortcomings that prohibit sound analyses of new firms’ development over time. Therefore, the Centre for European Economic Research (ZEW), KfW Bankengruppe and Creditreform are cooperating to form a start-up panel for...

We examine the relation between consumer search and equilibrium prices when collusion is endogenously determined. We develop a theoretical model and show that average price is a U-shaped function of the measure of searchers: prices are highest when there are no searchers (local monopoly power)...

This paper studies the impact of process and product innovations introduced by firms on employment growth in these firms. A simple model that relates employment growth to process innovations and to the growth of sales separately due to innovative and unchanged products is developed and estimated...

The literature on vertical integration in markets with regulated upstream prices suggests that the integrated upstream firm might engage in non-price discrimination. Several studies provide policy recommendations derived either from case study approaches or based on theoretical modeling which...

Using personnel records from a single large German firm in the financial industry, this paper provides detailed evidence on the effect of age and the supervisor's gender on gender differences in workplace training, holding constant various workplace characteristics. We implement an age-specific...
