The increasing commercialization of university discoveries has initiated a controversy on the impacts for future scientific research. It has been argued that an increasing orientation towards commercialization may have a negative impact on more fundamental research efforts in science. Several...

Job mobility and employment durations can be explained by different theoretical approaches, such as job matching or human capital theory or dual labor market approaches. These models may, however, apply to different degrees at different durations in the employment spell. Standard empirical...

Using a newly constructed macroeconometric model for Germany and the rest of the Euro area, we investigate the macroeconomic effects of structural labor market reforms in Germany. We find that neither the fact that Germany can no longer pursue an independent monetary policy nor the possibility...

The 2005 reform of the German welfare system introduced two competing organizational models for welfare administration. In most districts, a centralized organization was established where local welfare agencies are bound to central directives. At the same time, 69 districts were allowed to opt...

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...

This paper analyses the determination of match attendance in the German premier football league by applying models derived from Peel/Thomas (1992) and Janssens/Késenne (1987). Additionally we develop an improved version, where we incorporate the supporter clubs and the weather conditions as...

Using a Mincer-type wage function, we estimate cohort effects in the returns to education for West German workers born between 1925 and 1974. The main problem to be tackled in the specification is to separately identify cohort, experience, and possibly also age effects in the returns. For women,...

The theoretical discussion concerning the question whether the incumbent or the (potential) entrant invests more into R&D has attracted considerable interest. This paper reports the results of an empirical study on this question using data of about 3500 German firms over the years 1992 to 1995....

This paper discusses the incentives for innovation when liability is limited or not. Clearly innovative activity involves risk. On the one hand, the risk of firm owners is limited if their liability is limited. On the other hand credits will be more difficult to receive if liability is limited....
