Do Dishonesty, Ambiguity and Ethical Behaviour Affect? Risk Aversion?

Ambiguity and Ambiguity Aversion

Consider the following choice problem, known as “Ellsberg’s three-color urn example”, or simply the “Ellsberg Paradox” (Ellsberg [7]). An urn contains 30 red balls, and 60 green and blue balls, in unspecified proportions; subjects are asked to compare (i) a bet on a red draw vs. a bet on a green draw, and (ii) a bet on a red or blue draw vs. a bet on a green or blue draw. If the subject wins a ...

Gender Differences in Risk Aversion and Ambiguity Aversion

Gender Differences in Risk Aversion and Ambiguity Aversion This paper demonstrates gender differences in risk aversion and ambiguity aversion. It also contributes to a growing literature relating economic preference parameters to psychological measures by asking whether variations in preference parameters among persons, and in particular across genders, can be accounted for by differences in pe...

Children do not exhibit ambiguity aversion despite intact familiarity bias

The phenomenon of ambiguity aversion, in which risky gambles with known probabilities are preferred over ambiguous gambles with unknown probabilities, has been thoroughly documented in adults but never measured in children. Here, we use two distinct tasks to investigate ambiguity preferences of children (8- to 9-year-olds) and a comparison group of adults (19- to 27-year-olds). Across three sep...

Distortion risk measures, ambiguity aversion and optimal effort

We consider the class of concave distortion risk measures to study how choice is influenced by the decision-maker’s attitude to risk and provide comparative static results. We also assume ambiguity about the probability distribution of the risk and consider a framework à la Klibanoff, Marinacci, and Mukerji (2005) to study the value of information that resolves ambiguity. We show that this valu...
