Ideally we would like subjects of experiments to be perfect strangers so that the situation they face at the lab is not just a part of a long run interaction. Unfortunately, it is not easy to reach those conditions and experimenters try to mitigate any effects coming form these out-of- the-lab...

This paper explores new motivations behind giving. Specifically, it focuses on personal involvement and responsibility to explain why decision makers give positive amounts in dictatorial decisons. The experiment is designed to uncover these motivations. Subjects face the problem of a dictator's...

Recent papers on double-blind dictator games have obtained significant generous behavior when information regarding recipient is provided. But the lack of information disincentives other-regarding behavior and then, the subject’s behavior closely approximates the game theoretic prediction...

Over the last two decades there has been a complex debate about the nature and limits of the consequentialism. Using these ideas this paper revises giving (altruism) in experimental dicatator games. We use results from several experimental papers plus an experiment ad-hoc designed to motivate...

We report experimental data on expectations about generosity in a dictator game in which dictators first divide the pie and then make a guess about the donation of other dictators. In our experiment, recipients have to guess the donation that they are going to receive from their own dictator as...

We implement the Rawlsian veil of ignorance in the laboratory. Our experimental design allows separating the effects of risk and social preferences behind the veil of ignorance. Subjects prefer more equal distributions behind than in front of the veil of ignorance, but only a minority acts...

We implement the Rawlsian thought experiment of a veil of ignorance in the laboratory which introduces risk and possibly social preferences. We find that both men and women react to the risk introduced by the veil of ignorance. Only the women additionally exhibit social preferences that reflect...
