In this paper we conduct an analysis of the effects of firing costs in models that consider simultaneously worker heterogeneity, imperfect information on their productivity and union power. We consider an OLG model where heterogeneous workers participate in the labour market both when young and...

This paper compares models used to explain OECD unemployment. The models suggest that the ?natural rate of unemployment? has been driven up mainly by wage push factors. Panel data on twenty-two OECD countries are used to investigate the explanatory power of these models over the past two...

In this paper we analyze the frequently observed phenomenon that (i) some members of a team ("black sheep") exhibit behavior disliked by other (honest) team members, who (ii) nevertheless refrain from reporting such misbehavior to the authorities (they set up a "wall of silence"). Much cited...

This paper develops a model with multiple market locations in which the quality of intangible assets of firms, provided by management, determines the firms? performance. Despite an exante symmetry of potential entrants, the equilibrium assignment of heterogeneous managerial skills to firms tends...

This paper is a contribution to the debate on policy complementarity in relation to deregulation in the product and labour markets. We develop a model of dynamic efficiency wages and monopolistic competition. Whereas most of the literature points toward the gains associated to an increase in...

This paper examines the relationship between firms? wage offers and workers? supply of effort using a three-period experiment. In equilibrium, firms will offer deferred compensation: first period productivity is positive and wages are zero, while third period productivity is zero and wages are...

We analyze the topical question of how the compensation of elected politicians affects the set of citizens choosing to run. To this end, we develop a sparse and tractable citizen-candidate model of representative democracy with ability differences, informative campaigning and political parties....

We show experimentally that a principal?s distrust in the voluntary performance of an agent has a negative impact on the agent?s motivation to perform well. Before the agent chooses his performance, the principal in our experiment decides whether he wants to restrict the agents? choice set by...
