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...

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...

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...

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)...

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...

The paper aims at testing Florida's concept of the Creative Class using panel data for 323 West German regions for the time period 1975-2004. Applying a dynamic system approach based on GMM, we find that the local concentration of the Creative Class has predictive power for the economic...

Economic theory suggests that financing constraints may occur due to capital market imperfections. These particularly affect investments in innovation projects as such projects are typically characterized by a high degree of uncertainty, complexity and specificity. Financing innovation...

This article considers cognitive distance and combined competence as predictors of success in co-operative Research and Development (R&D) projects of firms. The concepts of cognitive distance and combined competence are operationalised based upon a dedicated survey, answered by matched pairs of...
