We propose a class of multiple-prior representations of preferences under ambiguity where the belief the decision … Optimism. The model does not restrict the sign of the DM's ambiguity attitude, and we show that it provides a unified framework … through which to characterize different degrees of ambiguity aversion, as well as to represent context-dependent negative and …

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 …

This paper analyzes dynamic choice for ambiguity-sensitive decision makers. It demonstrates that unambiguous behavioral … sophisticated MEU preferences are then used to analyze the value of information under ambiguity; a basic trade-off between …
