This paper studies how updating affects ambiguity attitude. In particular we focus on generalized Bayesian updating of … the Jaffray–Philippe sub-class of Choquet Expected Utility preferences. We find conditions for ambiguity attitude to be … the same before and after updating. A necessary and sufficient condition for ambiguity attitude to be unchanged when …

Representing ambiguity in the laboratory using a Bingo Blower (which is transparent and not manipulable) and asking the … empirically relevant models of behaviour under ambiguity, and compare their relative explanatory and predictive abilities. Our …

take-up rates for genetic tests are surprisingly low. We demonstrate that if individuals display ambiguity aversion, a … value of information to an ambiguity-averse decision-maker. Ambiguity aversion regarding test results thus provides an …

The recent spate of theoretical models of behaviour under ambiguity can be partitioned into two sets: those involving …

Few theoretically-consistent empirical models addressing the relationship between ambiguity, risk, and preferences for … the other over ambiguity about the risk. Using data from a survey of Nevada residents concerning risks from nuclear … from nuclear-waste transport perceived risks and ambiguity may be substantial.
