The random preference, Fechner (or "white noise"), and constant error (or "tremble") models of stochastic choice under risk are compared. Various combinations of these approaches are used with expected utility and rank-dependent theory. The resulting models are estimated in a random effects...

A decision maker's attitude towards risk is said to be of order (i), (i) = 1, 2, if for every given risk (e) with expected value zero, the risk premium the decision maker is willing to pay to avoid the risk (te) goes with (t) to zero at the same order as t[superscript i]. This article presents...

Much of the evidence raising doubts about expected utility theory (EUT) comes from experiments involving hypothetical decisions. Most of the rest of the evidence comes from experiments where respondents are asked to make a large number of decisions, knowing that only one of these will provide...

In this paper we study the feasibility of estimating a monetary value for a QALY (MVQ). Using two different surveys of the Spanish population (total n=892), we consider whether willingness to pay (WTP) is (approximately) proportional to the health gains measured in QALYs. We also explore whether...

<Para ID="Par1">We propose a broad framework for individual choice under risk which can accommodate many stochastic formulations of various deterministic theories. Using this framework to guide an experimental design, we show that most individuals’ departures from the independence axiom cannot be explained by...</para>

Many experiments investigating different decision theories have relied heavily on pairwise choices between lotteries. These are easy to incentivise, but often yield only limited dichotomous information. This paper considers whether respondents’ judgments about their strength of preference...

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...
