<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>

Models of stochastic choice are intended to capture the substantial amount of noise observed in decisions under risk. We present an experimental test of one model, which many regard as the default—the Basic Fechner model. We consider one of the model’s key assumptions—that the noise around...

The paper reports the results of a survey designed to elicit probability judgements for different types of events: ‘pure chance’ events, for which objective probabilities can be calculated; ‘public’ events, about which there may be some discussion in social groups and the media; and...

This article reports the results of a study designed to elicit willingness to pay (WTP) and willingness to accept (WTA) values for changes in the risk of nonfatal road injuries. We examine the possibility that individuals' preferences over combinations of wealth, risk, and safety are imprecise,...

During the past 40 years there has been an accumulation of experimental evidence suggesting that most of the axioms of expected utility theory are liable to be systematically violated by substantial numbers of individuals. Much of this evidence has focused in failures of the independence axioms...

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...
