This paper reports results from an experimental study that investigates insurance behaviours in low-probability high-loss risk situations. This study reveals that insurance behaviours may depend on the individual prior experience towards risk. It may also depend on the duration of the commitment...

This paper reports results from two experimental studies that investigate insurance behaviours in low-probability high-loss risk situations. The first study took place in France and the second one in Germany. These two studies reveal that insurance behaviours may depend on the past-experience...

We analyze a consumer-choice model with price uncertainty, loss aversion, and expectation-based reference points. The implications of this model are tested in an experiment in which participants have to make a consumption choice between two sandwiches. Participants differ in their reported taste...

The Lucas critique has been largely ignored in the marketing literature. We present a number of conditions under which the critique is most likely to (also) apply in marketing settings. Next, we provide some perspectives on how to diagnose and accommodate the Lucas critique, and identify various...

Biased perceptions of risks change the perceived value of insurance and the perceived returns to avoiding these risks. I show empirically that unemployed workers overestimate how quickly they will find work, but underestimate the return to their search efforts. I analyze the consequences for the...

An analytic approximation is derived for leverage levels that result from optimization of the logarithmic utility function associated with the Kelly criterion. An extension of this approximation, for the case when returns are drawn from a Student t-distribution, is then provided for a...

This paper treats the risk-averse optimal portfolio problem with consumption in continuous time with a stochastic-volatility, jump-diffusion (SVJD) model of the underlying risky asset and the volatility. The new developments are the use of the SVJD model with double-uniform jump-amplitude...

The paper introduces the concept of adjustment utility, that is, reference-dependent utility from expectations. It offers an explanation for observed preferences that cannot be explained with existing models, and yields new predictions for individual decision making. The model gives a simple...

Shane Frederick's recent paper in the Journal of Economic Perspectives reported some extremely surprising results - even allowing for everything we've learned about risk aversion and innumeracy. A survey that produced very different results raises further questions about (a) the exact role of...
