This paper follows up recent work on the relationship between (un-)employment and wage effects of social security financing undertaken by the OECD Jobs Study. Based on a simple macroeconometric model of the labour market, I investigate whether the peculiar OECD results for Germany on the...

Germany, 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 relates...

We analyze the effectiveness of publicly financed training and retraining programs in east Germany as measured by their effects on individual re-employment probabilities after training. These are estimated by discrete hazard rate models on the basis of individual-level panel data. We account for...

This paper develops a three stage oligopoly game for R&D cooperation, R&D expenditure and product market competition. In the first stage, firms decide whether or not to conduct R&D in cooperation with other firms. In the second stage the level of R&D investment is determined. Finally, firms...

Innovation activities in the German enterprise sector showed two opposing trends over the past two decades: While total innovation expenditures grew substantially, the number of firms conducting innovation activities fell sharply. Innovation expenditures hence concentrate on fewer firms. In this...

In this paper we analyze the conditions under which firms decide to offshore innovation. We consider the role of internal technological capabilities and technological dynamism in the firm environment, distinguishing speed and uncertainty of technological change. Using unique data from the German...

Multivariate Tobit models are estimated using German cross-sectional data to test whether strategic complementarities exist between expenditures in four different types of ICT-components. If two ICT-components are complements, they are correlated (provided that agents act rationally)....

Virtually all empirical firm-level studies on the demand for labor do not include labor cost in the econometric specification. This is due to the fact that business and innovation survey data usually lack information on labor cost. This paper shows how reliable skill-specific and firm-specific...

This paper investigates the impact of modern information and communication technologies on the demand for heterogeneous labor. It starts with an interrelated factor demand system. The "desired" level of employment, which is needed in such models, is derived from a generalized Leontief cost...
