Abstract

This paper presents the results of a survey-based experiment on the role of equity and efficiency for altruistic behavior. Using simple binary decisions for a representative pool of subjects, we find that both equity and efficiency are relevant for the decision to give. However, contrary to the findings in several laboratory experiments, our results indicate that equity plays a major role for altruistic behavior. Differences in relative payoffs have a significant effect on the decision to give. When giving is not costly, more than half of the subjects prefer equal payoffs to a socially efficient but unequal allocation. When giving is Pareto-improving, half the subjects choose to sacrifice a higher pay- off in order to avoid payoff inequality. We also find that preferences, as revealed by experimental choices, are largely consistent with reported pro-social activities, while only weakly related to self-reported well-being.
