Competence has been recently proposed as an explanation for the degree of ambiguity aversion. Using general knowledge … that the sum of certainty equivalents for both bets depends on the judged knowledge of the class of events. We also … elicited the decision weights for events and complementary events. We found a similar effect of knowledge on the sum of …

There is a large theoretical literature in both economics and psychology on decision making under ambiguity (as … design, in which we create genuine ambiguity in the laboratory and can control the amount of ambiguity, we generate data … how the fit changes when we vary the ambiguity. We find that the Choquet formulation performs best overall, though it is …

Several factors affect attitudes toward ambiguity. What happens, however, when people are asked to exchange an …
