This paper discusses models of choice under imprecise objective probabilistic information featuring beliefs about beliefs -- second order beliefs. A new model, called Second Order Dual Expected Utility (SODEU) featuring non-additive second order beliefs is introduced, axiomatized and...

We formulate a simple quantum decision model of the Ellsberg paradox. We report the results of an experiment we … source dependent model requires the specification of probability weighting functions in order to fit the evidence. On the … other hand, our quantum model makes no recourse to probability weighting functions. This suggests that much of what is …

Two of the most well known regularities observed in preferences under risk and uncertainty are ambiguity aversion and the Allais paradox. We study the behav- ior of an agent who can display both tendencies simultaneously. We introduce a novel notion of preference for hedging that applies to both...
