In this paper we conduct a theoretical analysis of the implications of a union which can exploit the existence of firm labour adjustment costs. We consider a model involving a large number of identical firms facing a single, economy-wide union. We solve (i) for the Markov perfect equilibria with...

We investigate a setting in which members of a population, bifurcated into a majority and a minority, transact with randomly matched partners. All members are uniformly altruistic, and each transaction can be carried out cooperatively or through a market mechanism, with cooperative transactions...

We develop a product market theory that explains why firms invest in general training of their workers. We consider a model where firms first decide whether to invest in general human capital, then make wage offers for each others? trained employees and finally engage in imperfect product market...

The demographic history of the Jews in the Middle Ages may be characterized by two main phenomena: i) a sharp drop in the number of Jews until the beginning of the modern period, due mainly to conversions; and, ii) early urbanization. Until now, these features have been analyzed as primarily...

Die Kompetenzverteilung in Genossenschaften zwischen Mitgliedern und Genossenschaftsbetrieb führt zu einer Organisationsform zwischen Hierarchie und Wettbewerb. Sowohl Mitglieder als auch das Management erhalten Teile der Entscheidungsbefugnis. In dieser Arbeit wird gezeigt, dass die...

This paper addresses the question of delegation in a partial contracting set-up, where only the control over actions is contractible. We consider an organization that should take two decisions, affected by a common state of the world parameter only known by the agent. We show that, if the...

In this paper we deal with voluntary and compulsory redistribution in an economy where the enforcement of property rights is costly. Two agents engage in a common-pool contest and two types of potential distortions arise: the waste of resources in the contest and the dilution of incentives to...

Many experiments indicate that most individuals are not purely motivated by material self interest, but also care about the well being of others. In this paper we examine tournaments among inequity averse agents, who dislike disadvantageous inequity (envy) and advantageous inequity (compassion)....

The paper reports laboratory experiments on a day-to-day route choice game with two routes. Subjects had to choose between a main road M and a side road S. The capacity was greater for the main road. 18 subjects participated in each session. In equilibrium the number of subjects is 12 on M and 6...

Numerous laboratory experiments show that workers reciprocate to high wages with high effort, when there is perfect information on the surplus created. Recent field experiments, however, suggest that trust and reciprocity may be lower or absent when the information is incomplete. We report a...
