Many violations of the Independence axiom of Expected Utility can be traced to subjects' attraction to risk-free prospects. Negative Certainty Independence, the key axiom in this paper, formalizes this tendency. Our main result is a utility representation of all preferences over monetary...

One of the most well-known models of non-expected utility is Gul (1991)'smodel of Disappointment Aversion. This model, however, is defined implicitly,as the solution to a functional equation; its explicit utility representation is unknown,which may limit its applicability. We show that an...

We study stochastic choice as the outcome of deliberate randomization. After first deriving a general representation of a stochastic choice function with such property, we proceed to characterize a model in which the agent has preferences over lotteries that belong to the Cautious Expected...
