This paper describes an experiment where respondents were asked to tackle two decision tasks which were very similar in structure but which differed in that one problem involved direct money payoffs while the other involved payoffs in the form of probabilities of winning a given sum of money....

There is some evidence that, as individuals participate in repeated markets, "anomalies" tend to disappear. One interpretation is that individuals — particularly marginal traders — are learning to act on underlying preferences which satisfy standard assumptions. An alternative...

Preference reversal is often explained as an information-processing effect, whereby individuals respond differently to valuation problems than to straight choices. Regret theory offers the alternative explanation that individuals act on consistent, but nontransitive, preferences. Regret theory,...

Although transitivity is often regarded as an indispensable principle of rational choice under uncertainty, some decision models allow nontransitive preferences. One of these--regret theory--is consistent with a particular pattern of choice cycles when payoffs are nonnegative and the opposite...

Much of the experimental evidence concerning violations of von Neumann-Morgenstern expected utility theory has been collected fr om experiments designed with conventional theory in mind and does not provide direct tests of alternative models such as regret theory and disappointment theory. This...
