Labour market reforms that are designed to stimulate labour supply at the lower end of the wage distribution can never be precisely restricted to affect only the target group. Spillovers to and feedback from other segments of the labour market are unavoidable and may counteract the direct...

Changing the income tax progressivity in labour markets with collective wage bargaining generates a trade-off. On the one hand, higher progressivity distorts individual labour supply decisions at the hours-of-work margin, on the other hand, it reduces unemployment by exerting downward pressure...

Codetermination can be regarded as an extreme regulatory intervention of the legislator in the labor market which might affect the efficiency of production and the bargaining power of labor. Based on a model that covers both efficient bargaining and employment bargaining a simple equation is...

In labour markets with collective wage bargaining higher progressivity of the labour income tax creates a trade-off. On the one hand, wages are lowered and unemployment decreases, on the other hand, the individual labour supply decision is distorted at the hours-of-work margin. The optimal level...

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....

Contrary to previous literature we hypothesize that interests of labor may well – like that of shareholders – aim at securing the long-run survival of the firm. Consequently, employee representatives on the supervisory board could well have an interest in increasing incentive-based...

We estimate the effect of R&D spillovers on sales realized by products new to the firm (imitation) and new to the market (innovation). It turns out that spillovers from rivals lead to more imitation, while inputs from customers and research institutions enhance original innovation.

We compare two options of integrating discrete working time choice of heterogenous households into a general equilibrium model. The first, known from the literature, produces household heterogeneity through a working time preference parameter. We contrast this with a model that directly...
