We proffer a method to assess the adequacy of expected utility theory (EUT) in empirical studies involving discrete and continuous choices. The method calibrates a utility function to revealed choices and rejects EUT for absurd degrees of implied concavity over the wealth at risk. We find EUT...

Recently, Rabin criticized the use of diminishing marginal utility in explaining risk aversion in small gambles with a mathematical theorem, which compares revealed risk averting behavior in small gambles to the risk behavior implied by expected utility theory in somewhat larger gambles, using...
