In the theory of psychological games it is assumed that players' preferences on material consequences depend on endogenous beliefs. Most of the applications of this theoretical framework assume that the psychological utility functions representing such preferences are common knowledge. But this...

Experimental evidence suggests that agents in social dilemmas have belief-dependent, other-regarding preferences. But in experimental games such preferences cannot be common knowledge, because subjects play with anonymous co-players. We address this issue theoretically and experimentally in the...

This paper compares the ability to select the efficient policy of a parliamentary and a presidential constitutional setup. In order to do it we build a dynamic theoretical model with asymmetric information that succeeds in addressing both the politicians accountability and the competence...

This paper studies the effect of social comparison on risk taking behavior. We assume that decision makers evaluate consequences of their choices not only as variations with respect to their economic status but also as variations with respect to the status of their peers. We test experimentally...

This paper models a purely informational mechanism behind the incumbency advantage. In a two-period electoral campaign with two policy issues, a specialized incumbent and an unspecialized, but possibly more competent challenger compete for election by voters who are heterogeneously informed...

In this paper we propose a model with uncertainty in which strategic voters vote, under poportional rule, for a Parliament and parties bargain to form a government. We prove that only consensus government form and only extreme parties take votes.

Constitutional structures shape politicians' behaviour and hence policy outcomes through the different incentive schemes at work. In this paper we analyse these mechanisms in parliamentary and presidential systems. Such a comparison is carried over by analysing how the two systems are able to...
