We specify and estimate an econometric model which separately identifies distributional preferences and the effects of perceived intentions on responder behavior in the ultimatum game. We allow the effects of perceived intentions to depend, among other things, on the subjective probabilities...

Abstract: We report results from three well-known experimental paradigms, where we use time, rather than money, as the salient component of subjects’ incentives. The three experiments, commonly employed to study social preferences, are the dictator game, the ultimatum game and the trust game....

Departures from pure self interest in economic experiments have recently inspired models of "social preferences". We conduct experiments on simple two-person and three-person games with binary choices that test these theories more directly than the array of games conventionally considered. Our...

Some current utility models presume that people are concerned with their relative standing in a reference group. If this is true, do certain types care more about this than others? Using simple binary decisions and self-reported happiness, we investigate both the prevalence of ``difference...

We study how to promote compliance with rules in everyday situations. Having access to unique data on the universe of users of all public libraries in Barcelona, we test the effect of sending email messages with dierent contents. We find that users return their items earlier if asked to do so in...

We compare behavior in modified dictator games with and without role uncertainty. Subjects choose between a selfish action, a costly surplus creating action (altruistic behavior) and a costly surplus destroying action (spiteful behavior). While costly surplus creating actions are the most...

We examine the degree of trust and trustworthiness in an experimental trust game with 662 participants from six different age groups, ranging from 8-year-olds to retired persons. Although both trust and trustworthiness have been identified as fundamental pillars for efficient economic...

We studied the decision making process in the Dictator Game and showed that decisions are the result of a two-step process. In a first step, decision makers generate an automatic, intuitive proposal. Given sufficient motivation and cognitive resources, they adjust this in a second, more...

We present a lab-field experiment designed to assess systematically the external validity of social preferences elicited in a variety of experimental games. We do this by comparing behavior in the different games with a number of behaviors elicited in the field and with self-reported behaviors...
