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...

Germany1, as most other European countries, has been plagued by a persistently high level of long?term unemployment since the early 1980's. In contrast, long? term unemployment is much less of a problem in the United States. One potential reason for the different structure of unemployment...

We analyze the dramatic decline of the employment share of unskilled labor in the West German economy, in particular its relation to the relatively rigid earnings structure. We find that the substitution elasticity between unskilled and skilled labor is rather low in most sectors of the economy....

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...

This paper investigates the drivers and the effects of the internationalisation of innovation activities in SMEs based on a large data set of German firms covering the period 2002-2007. We look at different stages of the innovation process (R&D, design, production and sales of new products, and...

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...

Although explanations of the persistence of high unemployment in Germany, in particular long-term unemployment, have increasingly focused on structural factors, there is only very limited evidence on their empirical importance so far. In this paper, these factors are analyzed based on a...

A dynamic random effects probit model is estimated on the first six waves of the German Socio-Economic Panel to test for state dependence effects in male unemployment behaviour. Estimation of the model is based on the marginal likelihood approach. In the model an individual's unemployment...
