Based on a large data set containing information on occupations between 1979 and 1999, this study explores the ?black box? surrounding the skill?biased technological change hypothesis by analyzing the mechanisms that induce information technologies to be complementary to employees with higher...

In this paper, we examine how parental health affects children's development of personality traits and problem behavior. Based on a German mother-and-child data base, we draw on observed parental health shocks as a more exogenous source of health variation to identify these effects and control...

We examine how parental health shocks affect children's non-cognitive skills. Based on a German mother-and-child data base, we draw on significant changes in selfreported parental health as an exogenous source of health variation to identify effects on outcomes for children at ages of three and...

This study analyses the effectiveness of targeted public support for R&D investment. In particular, we test whether the specific policy design aiming at incentivizing (international) collaboration and R&D in small and mediumsized firms achieves the desired objectives on input as well as output...

This paper analyses the level of relative specialisation in terms of gross fixed capital formation in EU regions for the period between 1985 and 1994. Controlling for heteroscedasticity and potential endogeneity problems, we get consistent econometric results. Larger market and regional sizes...

This study analyses relative sectoral specialisation of EU regions on the basis of investment and employment patterns. Controlling for heteroscedasticity and potential endogeneity in the econometric analysis, we find that relative specialisation in manufacturing sectors is higher in central...

This paper analyses the level of relative specialisation in terms of gross fixed capital formation in EU regions. Larger market and regional sizes diminish; a higher unemployment rate, population density, the fact of being a central region, the distance to the economic centre, and economic...

This paper analyzes the effects of public R&D funding on R&D expenditure and patenting behavior of German firms. The main focus is the direct impact of subsidies on R&D and the indirect effect on innovation output measured by patent applications. We distinguish the productivity of purely...

Valuable knowledge emerges increasingly outside of firm boundaries, in particular in public research institutions and universities. The question is how firms organize their interactions with universities effectively to acquire knowledge and apply it successfully. Literature has so far largely...
