Certain and Uncertain Utility: The Allais Paradox and Five Decision Theory Phenomena∗
نویسندگان
چکیده
In the study of decision making under risk, preferences are assumed to be continuous. We present a model of discontinuous preferences over certain and uncertain outcomes. Using existing parameter estimates for certain and uncertain utility, five important decision theory phenomena are discussed: the certainty effect, experimentally observed probability weighting, the uncertainty effect, extreme experimental risk aversion and quasi-hyperbolic discounting. All five phenomena can be resolved. JEL classification: D81, D90

Similarity and Decision-making under Risk (Is There a Utility Theory Resolution to the Allais Paradox?)
It is argued that the Allais paradox reveals a certain property of the decision scheme we use to determine the preference of one lottery over another. The decision scheme is based on the use of similarity relations on the probability and prize spaces. It is proved that for every pair of similarity relations there is essentially only one preference consistent with the decision scheme and the sim...
متن کاملMeasurable Ambiguity†
We introduce and analyze expected uncertain utility theory (EUU). A prior and an interval utility characterize an EUU decision maker. The decision maker uses her subjective prior to transform each uncertain prospect f into an interval-valued prospect f which assigns an interval [x, y] of prizes to each state. The decision maker ranks prospects according to their expected interval utilities E(u(...
متن کاملChoice under Uncertainty; ‘Allais Paradox’ and its Paradoxical Implication
Human attitude towards risk is mixed. However, looking at the persuasive argument of diminishing marginal utility of wealth, academia has adopted risk aversion as the norm. Inculcating risk aversion, expected utility hypothesis (EUH) is used to rank risky options. ‘Allais paradox’ contradicted EUH but promoted the conviction of risk aversion intuitively on the basis of certainty effect. Most of...
متن کاملA Perspective on Recent Developments in Utility Theory
The Allais Paradox seems as fresh today as it was when first posed some 40 years ago. It has been discussed in the intervening decades and led to many suggestions for modifying, extending or abandoning standard subjective expected utility theory. It has also led to much discussion of the distinction between normative and descriptive models and their rôle in prescriptive decision support. It see...
متن کاملA Stochastic Expected Utility Theory
This paper proposes a new model that explains the violations of expected utility theory through the role of random errors. The paper analyzes decision making under risk when individuals make random errors when they compute expected utilities. Errors are drawn from the normal distribution, which is truncated so that the stochastic utility of a lottery cannot be greater (lower) than the utility o...
