We investigate the consequences of a pure income effect on the altruistic behavior of donors. Inequity aversion theories predict either no effect or a decrease in giving, whereas warm-glow theory predicts an increase in giving with an increase in the common income of donor and receiver....

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....

We study how to promote compliance with rules in every day 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 different contents. We find that users return their items earlier if asked to do...

We study experimentally how the ability to communicate affects the frequency and effectiveness of flexible and inflexible contracts in a bilateral trade context where sellers can adjust trade quality after observing a post-contractual cost shock and a discretionary buyer transfer. In the absence...

We study antisocial preferences in simple money-burning tasks. A decision maker can choose whether or not to reduce another person's payoff at an own cost. We vary across tasks the initial endowment of the decider and the victim. We find that most conventional expectations are refuted: Subjects...

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 most frequent...

We use subjects actions in modified dictator games to perform a within-subject classification of individuals into four different types of interdependent preferences: Selfish, Social Welfare maximizers, Inequity Averse and Competitive. We elicit beliefs about other subjects actions in the same...

This paper studies the relevance of equilibrium and nonequilibrium explanations of behavior, with respects to equilibrium refinement, as players gain experience. We investigate this experimentally using an incomplete information sequential move game with heterogeneous preferences and multiple...

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...
