We investigate in this paper the attitudes towards risk of bettors in British horse races. The model we use allows us to go beyond the expected utility framework and to explore various alternative proposals by estimating a multinomial model on a 34443-race dataset. We find that rank-dependent...

We study attitudes towards risk in the Rank Dependent Expected Utility (RDEU) model. This model replaces expected utility by another functional, which is characterised by two functions, a utility function on outcomes in conjunction with a probability-perception function. We use the notion of...

Normative models of behaviour under risk in the framework of expected utility (EU) or under uncertainty in the framework of subjective expected utility (SEU) are very limited. In this survey paper, it is shown that non-expected utility (non-EU) models based on the Choquet integral allow for much...

This paper explores the consequences of non-additive expected utility on risk-sharing and equilibrium in a general equilibrium set-up. We establish that convexity of an agent's preferences (or strong uncertainty aversion) is equivalent to the convexity of his capacity and concavity of his...

I analyze observed choice between lotteries from an outcome-oriented point of view in the framework of choice between random variables. I characterize a choice maker, who faces a choice situation between lotteries, by (1) a surmising process that associates, with a pair of lotteries, a set of...

We extend expected utility theory to situations in which the prizes incloude feelings about living with uncertainty. We provide two examples to show the impact of these anticipatory feelings on decision making.

Shackle's theory of decision-making under uncertainty and the background to it are outlined. Its major prediction about action-choice is set out and proved. An experimental design to test its veracity is described; a design that it is demonstrated will make it possible to discriminate between...

This article deals with demand for insurance with a background risk in a non-probabilized uncertainty framework where preferences are represented by a non-additive model of decision making. The Choquet expected utility model we use, generalizes expected utility and allows for a separation of the...
