The paper shows that financial market equilibria need not exist if agents possess cumulative prospect theory preferences with piecewise-power value functions. The reason is an infinite short-selling problem. But even when a short-sell constraint is added, non-existence can occur due to...

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...

In this paper, we first show that for classical rational investors with correct beliefs and constant absolute or constant relative risk aversion, the utility gains from structured products over and above a portfolio consisting of the risk-free asset and the market portfolio are typically much...

The paper first shows that financial market equilibria need not to exist if agents possess cumulative prospect theory preferences with piecewise-power value functions. This is due to the boundary behavior of the cumulative prospect theory value function, which might cause an infinite...

Structured investment products, also known as equity- or index-linked notes, have become immensely popular among retail investors in the last ten years. In this paper, however, we show that for classical rational investors the utility gains from structured products are typically much smaller...

We demonstrate that in simple 2×2 games (cumulative) prospect theory preferences can be (semi-)evolutionarily stable, in particular, a population of players with prospect theory preferences is stable against more rational players, i.e. players with a smaller degree of probability weighting. We...

We prove a formula for the computation of optimal financial investments in an expected utility framework with arbitrary (not necessarily concave) utility functions. This extends classical results on optimal financial investments for strictly concave utility functions and is of importance...

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...
