Evolutionary Stability of Prospect Theory Preferences
We demonstrate that in simple 2 × 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 mixed strategies. We also show that in a typical game with infinitely many strategies, the “war of at...
متن کاملOn the Evolutionary Origin of Prospect Theory Preferences
Prospect theory scholars have identified important human decision-making biases, but they have been conspicuously silent on the question of the origin of these biases. Here we create a model that shows preferences consistent with prospect theory may have an origin in evolutionary psychology. Specifically, we derive a model from risk-sensitive optimal foraging theory to generate an explanation f...
متن کاملModeling Agent's Preferences Based On Prospect Theory
It is well known that human preferences in decisions under risk do not always complies with expected utility theory (EUT). In fact, there are several effects that are inconsistent with basic tenets of EUT. Alternative theories have been proposed and perhaps the most well studied is Prospect Theory (PT). Recent work showed experimental results that support the idea that financial professionals m...
متن کاملEvolutionary stability and lexicographic preferences
We explore the interaction between evolutionary stability and lexicographic preferences. To do so, we define a limit Nash equilibrium for a lexicographic game as the limit of Nash equilibria of nearby games with continuous preferences. Nash equilibria of lexicographic games are limit Nash equilibria, but not conversely. Modified evolutionarily stable strategies (Binmore and Samuelson, 1992. J. ...
متن کاملExistence of CAPM Equilibria with Prospect Theory Preferences
Under the assumption of normally distributed returns, we analyze whether the Cumulative Prospect Theory of Tversky and Kahneman (1992) is consistent with the Capital Asset Pricing Model. We find that in every financial market equilibrium the Security Market Line Theorem holds. However, under the functional form for the utility index suggested by Tversky and Kahneman (1992) financial market equi...
