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...

There is ample evidence that user-producer interaction is an important factor for successful innovations. It is often claimed that user-producer interaction is most effcient in close proximity. On the other hand, innovations are a major determinant for the export performance of firms. Does this...

This paper analyses the effects of a social assistance reform in Germany. In contrast to studies which are based on microsimulation methods we use a computable general equilibrium model which incorporates a discrete choice model of labour supply to simulate a variety of reform scenarios. The...

We present a model that integrates the discrete working time choice of heterogenous households into a general equilibrium setting where wages are determined by sectoral bargaining between firms and trade unions. The model is calibrated to German micro and macro data. We then use it to analyse...

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...

Using a linked employer-employee data set, this paper analyses the relationship between firm-profitability and wages. Particular emphasis is given to the question of whether the sensitivity of wages to firm-specific rents varies with collective bargaining coverage. To address this issue, we...

The Internet is receiving increasing attention as a medium for technology transfer between public research and the enterprise sector. Based on a survey of public research units in natural sciences and engineering in Germany, we analyse the determinants of firm contacts established via the...

Non-technological innovation is an important element of firms? innovation activities that both supplement and complement technological innovation, i.e. the introduction of new products and new processes. We analyse the spread of nontechnological innovation in firms, their relation to...
