Building on the Herstein-Milnor mixture set axiomatization of expected utility theory, we employ multiple mixture operators each modeling a source of uncertainty to arrive at a definition of rich mixture sets. This enables a weakening of the reduction of compound lottery axiom leading to an...

The paper proposes a framework to extend regret theory to dynamic contexts. The key idea is to conceive of a dynamic decision problem with regret as an intra-personal game in which the agent forms conjectures about the behaviour of the various counterfactual selves that he could have been. We...

This paper analyzes optimal hedging of a tradable risk (e.g. price risk or exchange rate risk) with forward contracts in the presence of untradable inflation risk. Utility is defined over real wealth. Optimal forward positions are derived relative to a given initial exposure in the tradable...

We investigate the origin of stochastic choice and differentiate between three classes of models that account for it: Random Utility, Bounded Rationality, and Deliberate Randomization. We conduct an experiment in which subjects face the same questions repeated multiple times, but we consider...

Among the reasons behind the choice behavior of an individual taking a stochastic form are her potential indifference or indecisiveness between certain alternatives, and/or her willingness to experiment in the sense of occasionally deviating from choosing a best alternative in order to give a...

Virtually all current theories of choice under risk or uncertainty are cognitive and consequentialist. They assume that people assess the desirability and likelihood of possible outcomes of choice alternatives and integrate this information through some type of expectation-based calculus to...

This paper develops a theory of focusing and framing in an intertemporal context with risky choices. We provide a selection criterion between existing theories of fo- cusing by allowing a decision maker to choose her frame such that her attention is either drawn to salient events associated with...

People are sometimes risk-averse in gains but risk-loving in losses. Such behavior and other anomalies underlying prospect theory arise from a model of local status maximization in which consumers compare their wealth with other consumers of similar wealth. This social explanation shares key...
