Most experiments on decision theory ask individual subjects to make more than one decision. The isolation hypothesis is commonly used to justify the choice of the random lottery incentive mechanism as the preferred payoff protocol. This research note reports on the main findings on the...

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...

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...

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...
