This paper compares classical expected utility with the more general rank-dependent utility models. First we show that it is the difference between the independence condition for preferences of expected utility and its comonotonic generalization in rank-dependent utility, that provides the exact...

This article compares classical expected utility (EU) with the more general rank-dependent utility (RDU) models. The difference between the independence condition for preferences of EU and its comonotonic generalization in RDU provides the exact demarcation between EU and rank-dependent models....

Previous research suggests that human reaction to risky opportunities reflects two contradicting biases: "loss aversion", and "limited level of reasoning" that leads to overconfidence. Rejection of attractive gambles is explained by loss aversion, while counterproductive risk seeking is...
