We conduct a real-effort task experiment where subjects' performance translates into a donation to a charity. In a within-subjects design we vary the visibility of the donation (no/private/public feedback). Confirming previous studies, we find that subjects' performance increases, that is, they...

We study conditional cooperation based on a sequential two-person linear public good game in which a trusting first contributor can be exploited by a second contributor. After playing this game the first contributor is allowed to punish the second contributor. The consequences of sanctioning...

In our experiment, a dictator game variant, the reported outcome of a die roll determines the endowment (low/high) in a subsequent dictator game. In one treatment the experimenter is present and no cheating is possible, while in another subjects can enter the result of the roll themselves. Moral...

We analyze reciprocal behavior when moral wiggle room exists. Dana et al. (2007) show that giving in a dictator game is only partly due to distributional preferences as the giving rate drops when situational excuses for selfish behavior are provided. Our binary trust game closely follows their...

Interactions between players with private information and opposed interests are often prone to bad advice and inefficient outcomes, e.g. markets for financial or health care services. In a deception game we investigate experimentally which factors could improve advice quality. Besides advisor...

This paper aims to analize the role of personal identity in decision making. To this end, it starts by reviewing critically the growing literature on economics and identity. Considering the ambiguities that the concept of social identity poses, our proposal focuses on the concept of personal...

The higher our aspirations, the higher the probability that we have to adjust them downwards when forming more realistic expectations later on. This paper shows that the costs induced by high aspirations are not trivial. We first develop a theoretical framework to identify the factors that...

We investigate to what extent genuine social preferences can explain observed other-regarding behavior. In a social dilemma situation (a dictator game variant), people can choose whether to learn about the consequences of their choice for the receiver. We find that a majority of the people that...
