We find that in cumulative prospect theory (CPT) with a concave value function in gains, a lottery with finite expected value may have infinite subjective value. This problem does not occur in expected utility theory. We characterize situations in CPT where the problem can be resolved. In...

We extend the original form of Prospect Theory by Kahneman and Tversky from finite lotteries to arbitrary probability distributions, thus paving the way for applications in economics and finance. Moreover, we suggest a method how to incorporate a crucial step of the “editing phase” into...

Ambiguity aversion has been suggested as a potential explanation for the equity premium puzzle in recent theoretical models. To test this hypothesis, we measure the amount of ambiguity aversion in a large-scale international survey. A comparison to the average equity premia in these countries...

We examine time discounting factors in an international survey. Our analysis reveals a significant relationship between time discount factors and historical equity premiums across 27 countries. This result implies that higher historical equity risk premiums are observed in countries where survey...

"This book provides a comprehensive overview of the emerging field of cultural finance. It summarizes research results of cultural differences in financial decision making and on financial markets. Many of the results have been published in leading academic journals over the last ten years but...

We demonstrate that in simple 2 X 2 games (cumulative) prospect theory preferences can be evolutionarily stable, i.e. a population of players with prospect theory preferences can not be invaded by more rational players. This holds also if probability weighting is applied to the probabilities of...
