We propose an immigration policy based on the model of cooperatives. Incoming migrants have to acquire a participation certificate. In exchange, the immigrants may enter the country of choice without danger. The revenue goes to the country of the recipient nation rather than to human smugglers....

In this paper we conduct a laboratory experiment to test the extent to which Moore and Repullo’s subgame perfect implementation mechanism induces truth-telling in practice, both in a setting with perfect information and in a setting where buyers and sellers face a small amount of uncertainty...

Religious participation is much more widespread in the United States than in Europe, while Europeans tend to view sects more suspiciously than Americans. We propose an explanation for these patterns without assuming differences in preferences or market fundamentals. Religious markets may have...

Democratic societies are challenged by various violent and organized groups, be they terrorists, gangs or organized hooligans. In exchange for offering an identity, leaders in such groups typically require members to be violent. We introduce a simple model to capture these stylized facts, and...

We propose a formal concept of the power of voice in the context of a simple model where individuals form groups and trade in competitive markets. Individuals use outside options in two different ways. Actual outside options reflect the possibility to exit or to join other existing groups....

Interest groups are introduced in a spatial model of electoral competition between two political parties. We show that the presence of these interest groups increases the winning set, which is the set of policy platforms for the challenger that will defeat the incumbent. Therefore interest...

Empirical evidence reveals that unemployment tends to increase property crime but that it has no effect on violent crime. To explain these facts, we examine a model of criminal gangs and suggest that there is a substitution effect between property crime and violent crime at work. In the model,...

The paper analyzes the appointment of the European Commission as a strategic game between members of the European Parliament and the Council. The focal equilibrium results in Commissioners that duplicate the policy preferences of national Council representatives. Different internal decision...

This paper deals with the voting rules in the EU Council. Both internal and external impact of the voting rules are evaluated. Internal impact affects the distribution of power among the member states and external impact affects power relations between the main decision-making bodies in the EU....

This paper explored the determinants of survival in a life and death situation created by an external and unpredictable shock. We are interested to see whether pro-social behaviour matters in such extreme situations. We therefore focus on the sinking of the RMS Titanic as a quasi-natural...
