The discovered preference hypothesis appears to insulate expected utility theory (EU) from disconfirming experimental evidence. It asserts that individuals have coherent underlying preferences, which experiments may not reveal unless subjects have adequate opportunities and incentives to...

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,...

The random lottery incentive system is widely used in experimental economics to motivate subjects. This paper investigates its validity. It reports three experiments which compare responses given to decision tasks which are embedded in random lottery designs with responses in 'single choice'...

Using equivalent loss (the monetary loss equivalent to a proposed amenity reduction, EL) and equivalent gain (the gain equivalent to a proposed amenity increase, EG) alongside traditional welfare measures in a contingent valuation study of traffic disamenity, we report an experiment designed to...

Previous studies suggest that two otherwise robust 'anomalies' - preference reversals and disparities between buying and selling valuations - are eroded when respondents participate in repeated markets. We report an experiment which investigates whether this is true when factors neglected in...

The preference reversal phenomenon is usually interpreted as evidence of nontransitivity of preference, but has also been explained as the result of the difference between individuals' responses to choice and valuation problems; the devices used by experimenters to elicit valuations; and the...
