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...

Abstract. This paper develops a theory of revealed 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 growing literature reports the conclusions that: (a) expected utility theory does not provide a plausible theory of risk aversion for both small-stakes and large-stakes gambles; and (b) this decision theory should be replaced with an alternative theory characterized by loss aversion. This...

Abstract. This paper studies the effect of power asymmetry on resolution of social dilemmas in repeated play of linear public good games. The experiment uses a 2X2 design that crosses power symmetry or asymmetry in games with positive (provision) or negative (appropriation) externalities. Our...

We run a staged field experiment during three concerts in the South of Italy, characterized by the same traditional music and a comparable average level of alcohol consumption by attendees. Individual blood alcohol concentration (BAC) is measured with electronic breathalyzers. The experimental...

Weber, Shafir, and Blais (2004) advocate use of the coefficient of variation (CV) as a measure of risk sensitivity and apply CV in a meta-analysis of data for risky choices by humans and animals. We critically re-examine the CV measure as either a normative or descriptive criterion for decision...

Expected value theory has been known for centuries to be subject to critique by St. Petersburg paradox arguments. And there is a traditional rebuttal of the critique that denies the empirical relevance of the paradox because of its apparent dependence on existence of credible offers to pay...
