confidence and ambiguity attitudes in individual decision making. Different ambiguity settings not only can be determined by the … multistage experiment where subjects face different sources of ambiguity and where we are able to control for self …' ambiguity aversion. Our regressions show that the two measures are significantly correlated at the subject level, that the …

Ryan (2019), given a closed and convex set of priors, ambiguity-averse voters would select a prior from this set in a …

the α-MEU model of choice under ambiguity (Hurwicz, 1951) can overcome several challenges faced by the baseline model …

We consider a general framework of optimal mechanism design under adverse selection and ambiguity about the type …

We relate time-varying aggregate ambiguity (V-VSTOXX) to individual investor trading. We use the trading records of … an increase in ambiguity is associated with increased investor activity. It also leads to a reduction in risk …-taking which does not reverse over the following days. When ambiguity is high, the effect of sentiment looms larger. Survey …

We introduce a model of random ambiguity aversion. Choice is stochastic due to unobserved shocks to both information … and ambiguity aversion. This is modeled as a random set of beliefs in the maxmin expected utility model of Gilboa and … Schmeidler (1989). We characterize the model and show that the distribution of ambiguity aversion can be uniquely identified …

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 …
