This paper investigates how changes in work-related factors affect workers' absence and presenteeism behavior. Previous studies (implicitly) assume that there is a substitutive relationship, i.e. a change in a work-related factor decreases the level of absence and simultaneously increases...

Empirical evidence suggests that the bargaining power of trade unions differs across firms and sectors. Standard models of unionization ignore this pattern by assuming a uniform bargaining strength. In this paper, we incorporate union heterogeneity into a Melitz (2003) type model. Union...

This paper examines the decision-making process of students from an economic perspective in order to understand what determines an individual's willingness to provide effort. Our theoretical model predicts that ability and job market prospects are positive determinants. Analyzing a novel dataset...

Empirical evidence suggests that high-productivity firms face stronger trade unions than low-productivity firms. Then a policy that puts all unions into a better bargaining position is no longer neutral for firm selection as in models with a uniform bargaining strength across firms. Using a...

How does an increase in unionization costs, i.e. costs which arise when workers are organized by a union, affect the productivity distribution of active firms, wage inequality and welfare? In this paper, we build a model with costly, endogenous unionization, heterogeneous firms as well as free...

In a Cournot-oligopoly with free but costly entry and business stealing, output per firm is too low and the number of competitors excessive, assuming labor productivity to depend on the number of employees only or to be constant. However, a firm can raise the productivity of its workforce by...

If input markets are competitive and output per firm declines with the number of firms (business stealing effect), there will be excessive entry into a Cournot oligopoly for a homogeneous commodity. However, input markets are often imperfectly competitive and the price of labor is determined by...
