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

We study how the framework of classical game theory changes whenthe preferences of the players are described by Prospect Theory (PT)and Cumulative Prospect Theory (CPT) instead of Expected UtilityTheory. Specically, we study the inuence of framing eects and probabilityweighting on the existence...

Does gender play a role in the context of team work? Our results based on areal-effort experiment suggest that performance depends on the composition of theteam. We find that female and male performance di¤er most in mixed teams withrevenue sharing between the team members, as men put in...

Unlike previous attempts to implement cooperation in a prisoners’ dilemma gamewith an infinite horizon in the laboratory, we focus on extended prisoners’ dilemmagames in which a second (pure strategy) equilibrium allows for voluntary cooperationin all but the last round. Our four main...

During the last three decades the ascent of behavioral economics clearly helped tobring down artificial disciplinary boundaries between psychology and economics.Noting that behavioral economics seems still under the spell of the rational choicetradition – and, indirectly, of behaviorism – we...

In the experimental scenario several agents repeatedly invest in n (n _ 2)state-specic assets. The evolutionarily stable and equilibrium (Blume andEasley, 1992) portfolio for this situation requires to distribute funds accordingto the constant probabilities of the various states. The dierent...

We investigate the gender specific inter-temporal allocation behavior ofspouses with different deterministic life expectations in an experimentwhere the gender of one's partner is known. In each period of theirlife both partners propose a consumption level one of which is thenrandomly...

We investigate the intertemporal and interpersonal allocation behavior ofspouses with different deterministic life expectations in an experiment. In eachperiod of their life both partners propose a consumption level one of which isthen randomly implemented. In spite of the complex dynamics...

The paper examines a game-theoretic evolutionary model of a …-nancial market with endogenous equilibrium asset prices. Assetspay dividends that are partially consumed and partially rein-vested. The traders use general, adaptive strategies (portfoliorules), distributing their wealth between...

The paper examines a game-theoretic model of a …nancial market inwhich asset prices are determined endogenously in terms of short-runequilibrium. Investors use general, adaptive strategies depending onthe exogenous states of the world and the observed history of thegame. The main goal is to...
