Between 1991 and 1997 West Germany spent on average about 3.6 bn Euro per year on public sector sponsored training programmes for the unemployed. We base our empirical analysis on a new administrative data base that plausibly allows for selectivity correction by microeconometric matching...

We estimate the determinants of various types of product innovation. Knowledge spillovers from rivals have a positive impact on incremental innovations. This impact is largely independent of the participation in R&D cooperations. Spillovers exert no such independent influence on drastic...

This paper addresses three major aspects of firms' process innovative activity: forward- looking behaviour, uncertainty w.r.t. returns of R&D investments, and oligopolistic competition on the product market. Assuming that R&D expenditures are cost-reducing investments, we derive an Euler...

This paper investigates the link between variation in the supply of workers who participate in spe­cific types of active labour market policies (ALMPs) and firm performance using a new exception­ally informative German employer-employee data base. For identification we ex­ploit that German...

We evaluate a wage subsidy program that is targeted at long-term unemployed workers in Germany. We use an alternative identification procedure compared to empirical studies con­ducted so far. Exploiting the particular program regulations and large administrative data we estimate the impact of...

In this paper, we assess the impact of firms introducing part-time work schemes for gradual labour market exit of elderly workers on their employees' labour market outcomes. The analysis is based on unique linked employer-employee data that combine high-quality survey and administrative data....

This paper investigates the link between variation in the supply of workers who participate in specific types of active labour market policies (ALMPs) and firm performance using a new exceptionally informative German employer-employee data base. For identification we exploit that German local...

While available evidence suggests that the events of September 11th negatively influenced the relative earnings of employees with Arab background in the US, it is not clear that they had similar effects in other countries. Our study for Germany provides evidence that the events also affected the...

The 1/n problem potentially limits the effectiveness of profit sharing in motivating workers. While the economic literature suggests that reciprocity can mitigate this problem, it remains silent on the optimal degree of reciprocity. We present a representative model demonstrating that...

Using unique survey data from the German Socio-Economic Panel, this study examines the influence of reciprocal inclinations on workers' sorting into codetermined firms. Employees with strong negative reciprocal inclinations are more likely to work in firms with a works council while employees...
