This paper highlights a new social motivation, the indirect reciprocity, through a three-player dictator-ultimatum game. Player 2 has the opportunity to reward or punish indirectly the player 1 by inciting – with her offer - player 3 to accept or to reject the division. We implement three...

Substantial evidence has been accumulated in recent empirical works on the limited ability of the Nash equilibrium to rationalize observed behavior in many classes of games played by experimental subjects. This realization has led to several attempts aimed at finding tractable equilibrium...

The need for justification is a widely observed social phenomenon. This paper develops a theoretical framework and reports laboratory evidence to show how pure justification pressure affects cooperative behavior in economic exchange environments. In a one-shot anonymous interaction, compared...

Although there is an increasing interest in examining the relationship between cognitive ability and economic behavior, less is known about the relationship between cognitive ability and social preferences. We investigate the relationship between consequential measures of cognitive ability and...

We run a public good experiment in the field and in the lab with (partly) the same subjects. The field experiment is a true natural field experiment as subjects do not know that they are exposed to an experimental variation. We can show that subjects' behavior in the classic lab public good...

This paper presents evidence which challenges the view that techniques which are designed to measure the social preferences of subjects can always be accomplished in a nonintrusive manner. We find evidence that such measurements can influence the preferences which they are designed to measure....

An impure public good is a commodity that combines public and private characteristics in fixed proportions. Green goods such as dolphin-friendly tuna or green electricity programs provide increasings popular examples of impure goods. We design an experiment to test how the presence of impure...

The “Hedonistic Paradox” states that homo economicus, or someone who seeks happiness for him- or herself, will not find it, but the person who helps others will. This study examines two questions in connection with happiness and generosity. First, do more generous people, as identified in...

I ran an experiment in order to evaluate the relationship, if any, between power, or the search for power, and the degree of altruism. In particular I experimentally tested whether an organization structured in a strictly hierarchical way was able to reduce the degree of altruism of a group of...
