Is mutually beneficial cooperation in trust games more prevalent with private property or common property? Does the strength of property right entitlement affect the answer? Cox, Ostrom, Walker, et al. report little difference between cooperation in private and common property trust games. We...

This paper describes central topics in our research program on social preferences. The discussion covers experimental designs that discriminate among alternative components of preferences such as unconditional altruism, positive reciprocity, trust (in positive reciprocity), negative reciprocity,...

This paper reports three experiments with triadic or dyadic designs. The experiments include the moonlighting game in which first-mover actions can elicit positively or negatively reciprocal reactions from second movers. First movers can be motivated by trust in positive reciprocity or fear of...

Departures from quot;economic manquot; behavior in many games in which fairness is a salient characteristic are now well documented in the experimental economics literature. These data have inspired development of new models of social preferences incorporating inequality aversion and...

This paper develops a nonparametric theory of preferences over one's own and others' monetary payoffs. We introduce more altruistic than (MAT), a partial ordering over preferences, and interpret it with known parametric models. We also introduce and illustrate more generous than (MGT),a partial...

This paper addresses four stylized facts that summarize data from experimental studies of voluntary contributions to provision of public goods. Theoretical propositions and testable hypotheses for voluntary contributions are derived from two models of social preferences, the inequity aversion...

Theories of decision under risk that assume decreasing marginal utility of money have been critiqued with concavity calibration arguments. Since that critique uses varying payoffs and fixed probabilities, it cannot have implications for calibration of nonlinear probability transformation, which...

Departures from "economic man" behavior in many games in which fairness is a salient characteristic are now well documented in the experimental economics literature. These data have inspired development of models of social preferences that assume agents have preferences for equity and efficiency...

Centipede games and Dutch auctions provide important instances in which game theory fails empirically. The reasons for these empirical failures are not well understood. Standard centipede games and Dutch auctions differ from each other in terms of their Institutional Format (IF), Dynamic...

We introduce a parametric model of other-regarding preferences in which my emotional state determines the marginal rate of substitution between my own and others' payoffs, and thus my subsequent choices. In turn, my emotional state responds to relative status and to the kindness or unkindness of...
