A major virtue of von Neumann-Morgenstern utilities, for example, in the theory of general financial equilibrium (GFE), is that they ensure time consistency: consumption-portfolio plans (for the future) are in fact executed (in the future) — assuming that there is perfect foresight about...

Loss aversion, risk aversion, and the probability weighting function (PWF) are three central concepts in explaining decisionmaking under risk. I examine interlinkages between these concepts in a model of decisionmaking that allows for loss averse/tolerant stochastic reference dependence and...

The paper develops an axiomatic framework for rational decision making. The von Neumann-Morgenstern axioms give rise to a richer risk attitude than that captured in the standard discounted expected utility model. I derive three models that permit a more comprehensive risk evaluation. These...

The most commonly employed decision making paradigms are expected utility, prospect theory and regret theory. We examine the simple heuristic of maximizing the probability of being ahead, which in some natural economic situations may be in contradiction to all three of the above fundamental...

Experiments typically rely on small payments to incentivize participants. This works if participants view these payments as fungible with their own money, but if participants view the payments as a windfall, they may behave differently in experiments than in real life. We modify standard risky...

Preferences over risky alternatives can be elicited by different methods, including direct pairwise choices and willingness-to-accept valuations. The results are frequently at odds, casting doubts on the foundations of economics. We develop a stochastic choice model predicting when...

Experiments on intertemporal consumption typically show that people have difficulties in optimally solving such problems. Previous studies have focused on contexts in which agents are faced with risky future incomes and have to plan over long horizons. We present an experiment comparing decision...

We formulate a general theory of preferences over outcome-time-probability triplets and decompose uncertainty into risk and hazard. We define the delay, defer, shift and certainty functions that can be uniquely elicited from behaviour. These individually determine stationarity, the common...

This paper presents an axiomatic approach to separately control for the attitudes toward intertemporal substitution and risk aversion under the EUT. The standard time-separable form is recovered when the functions dictating the two attitudes are identical. This approach differs from Kihlstrom...

This paper tests an intertemporal consumption-leisure model with non-expected utility. There is evidence to reject the commonly used expected-utility specification and to accept the non-expected utility one as the model's restrictions are not rejected by the data
