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...

Social lotteries are lotteries that are played along with someone else. The experimental literature indicates that risk attitudes depend on how one's situation in the safe alternative compares to that of a peer. Evaluation of the risky alternative also depends on whether the lottery gives equal...

We study experimentally whether heterogeneity of behavior in the Centipede game can be interpreted as the result of a learning process of individuals with different preference types (more and less pro-social) and coarse information regarding the opponent's past behavior. We manipulate the...

Willingness to take risk depends on whether the risk affects others as well as oneself and on how the risk affects one´s position vis-á-vis others. Taking a bet can improve one´s position relative to others or threaten it. We present an experiment that explores individual attitudes to...

Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively-colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss important extensions of the standard...

We explore experimentally how power asymmetries between partners affect relationship-specific investments. We find that on average players' investments are larger than equilibrium investments. In contrast to social dilemma experiments, in our experiment preferences for social welfare and those...

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...

Does geographic distance or the perceived social distance between subjects significantly affect proposer and responder behavior in ultimatum bargaining? To answer this question, subjects play a one-shot ultimatum game with three players (proposer, responder, and a passive dummy player) and...

The study of gender differences in social preferences has shown mixed results, preventing economists and other social scientists from drawing definitive conclusions on this topic. Several original investigations and experimental reviews have hypothesized that the main reason of this...

We consider guilt averse agents and principals and study the effects of guilt on optimal behavior of the principal and the agent in a moral hazard model. The principal's contract proposal contains a target effort in addition to the monetary incentive scheme. By accepting the agreement, the...
