We empirically show that sample information not only moderates prospects' outcome ambiguity but also decision makers' revealed aversion of them. Since most natural prospects permit at least some sample inference, accounting for their degree of ambiguity improves prediction of aversion. The...

Most researchers who analyze producers' preferences under uncertainty report that producers are averse towards risk and ambiguity scenarios. This aversion has an influence on producers' decision-making processes; hence the relevance of determining and analyzing these preferences as a key factor...

The probability triangle (also called the Marschak-Machina triangle) allows for compact and intuitive depictions of risk preferences. Here, we develop an analogous tool for choice under uncertainty - the ambiguity triangle - and show that indifference curves in this triangle capture preferences...

People often need to choose between alternatives with known probabilities (risk) and alternatives with unknown probabilities (ambiguity). Such decisions are characterized by attitudes towards ambiguity, which are distinct from risk attitudes. Studies of ambiguity attitudes have thus far focused...

We study uncertainty averse preferences, that is, complete and transitive preferences that are convex and monotone. We establish a representation result, which is at same time general and rich in structure. Many objective functions commonly used in applications are special cases of this...
