We introduce a simple, easy to implement instrument for jointly eliciting risk and ambiguity attitudes. Using this … instrument, we structurally estimate a two-parameter model of preferences. Our findings indicate that ambiguity aversion is … significantly overstated when risk neutrality is assumed. This highlights the interplay between risk and ambiguity attitudes as well …

An extensive literature has studied ambiguity aversion in economic decision making, and how ambiguity aversion can … general dislike of ambiguity. In this paper, we provide a systematic experimental assessment of ambiguity attitudes in … more than 500 participants and find that ambiguity aversion is the exception, not the rule. We replicate the usual finding …

This paper proposes a decision-theoretic framework for experiment design. We model experimenters as ambiguity …

We show that ambiguity aversion increases the value of a statistical life as soon as the marginal utility of wealth is … higher if alive than dead. The intuition is that ambiguity aversion has a similar effect as an increase in the perceived … baseline mortality risk, and thus operates as the "dead anyway" effect. We suggest, however, that ambiguity aversion should …

We study risk attitudes, ambiguity attitudes, and time preferences of 661 children and adolescents, aged ten to … mass index, are less likely to save money and show worse conduct at school. Experimental measures for risk and ambiguity …

contribution, the paper extends the smooth ambiguity model by providing a threefold disentanglement between, risk aversion …, ambiguity aversion, and the propensity to smooth consumption over time. …

This paper studies how updating affects ambiguity-attitude. In particular we focus on the generalized Bayesian update … of the Jaffray-Phillipe 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 …
