'Stochastically more risk averse:' A contextual theory of stochastic discrete choice under risk

Abstract: Microeconometric treatments of discrete choice under risk are typically homoscedastic latent variable models. Specifically, choice probabilities are given by preference functional differences (given by expected utility, rank-dependent utility, etc.) embedded in cumulative distribution functions. This approach has a problem: Estimated utility function parameters meant to represent agents' degree of risk aversion in the sense of Pratt (1964) do not imply a suggested "stochastically more risk averse" relation within such models. A new heteroscedastic model called "contextual utility" remedies this, and estimates in one data set suggest it explains (and especially predicts) as well as or better than other stochastic models.
