We propose and axiomatically characterize dynamically consistent update rules for decision making under ambiguity … of preferences over acts, to be able to reconcile typical behavior in the face of ambiguity (as exemplified by Ellsberg …’s paradox) with dynamic consistency for all non-null events. Updating takes the form of applying Bayes’ rule to subsets of the …

equivalent consistency under updating characterise a family of capacities, called Genralised Neo-Additive Capacities (GNAC). This …

Observed individual behavior in the presence of ambiguity is characterized by insufficient responsiveness to changes in … subjective likelihoods. Such likelihood insensitivity under ambiguity is integral to theoretical models and predictive of … and determining factors. This paper investigates the role of beliefs in the form of ambiguity perception - the extent to …

The α-MEU model and the smooth ambiguity model are two popular models in decision making under ambiguity. However, the …

This paper develops a belief update rule under ambiguity, motivated by the maxim: in the face of new information …, Maximum Likelihood) are special cases, but avoids the problems that these rules have with updating on complete ignorance …

This paper analyzes dynamic choice for ambiguity-sensitive decision makers. It demonstrates that unambiguous behavioral … decision models and updating rules, and delivers unambiguous welfare comparisons. As an example, a characterization of prior …-by-prior Bayesian updating and Consistent Planning for arbitrary maxmin-expected utility preferences is presented. The resulting …

Regarding symmetry assumptions, we show that, under relatively mild conditions, a variety of preference … stringent. Only when it is satisfied may the Bewley set be interpreted as reflecting only perceived ambiguity and not also taste …

regarding the realization likelihood of cash flows, the subjective attitude towards risk, and the attitude towards ambiguity …. While previous literature looks at the total price discount under ambiguity, this paper investigates with laboratory … belief effects, the risk premiums, and the ambiguity premiums from each other. Both methods lead to similar results: Overall …
