Combining rational choice and evolutionary dynamics : the indirect evolutionary approach

Königstein, Manfred; Müller, Wieland - 1999

In this study we propose a formal framework for the indirect evolutionary approach as initiated by Güth and Yaari (1992). It allows to endogenize preferences and to study their evolution. We define two-player indirect evolutionary games with observable types and show how to incorporate...

No free lunch for large investors

Bank, Peter - 1999

We study an extension of the classical B1ack-Scholes model which accounts for feedback effects from trading in an imperfectly elastic market. The proposed semi-martingale model may be viewed as a compromise between the diffusion approach in, e.g., (Cuoco and Cvitanic 1998), (Cvitanic and Ma...

On the regulation of social norms

Kübler, Dorothea - 2000

A model is developed to understand how norms can be influenced by "norm entrepreneurs", e.g. lawmakers, government agencies, unions etc. Two instruments of influencing the dynamics of normfollowing behavior are analyzed, namely transforming the (monetary) incentives and changing the meaning or...

From full to bounded rationality : the limits of unlimited rationality

Güth, Werner; Kliemt, Hartmut - 2001

choice making. We illustrate why this role is not being fulfilled well by standard models of full rationality and that … theories of bounded rationality are needed not only for better predictions, but also for developing better advice. Our main … point is that one cannot succeed here without studying how theories of bounded rationality causally influence the behavior …

Framing effects on asset markets : an experimental analysis

Kirchler, Erich; Maciejovsky, Boris; Weber, Martin - 2001

In this paper we investigate four hypotheses which are inconsistent with expected utility theory, but may well be explained by prospect theory. It deals with framing, the non-linearity of subjective probabilities, the disposition effect, and the correspondence of different experimental risk...

Simultaneous over- and underconfidence : evidence from experimental asset markets

Maciejovsky, Boris; Kirchler, Erich - 2001

In this paper individual overconfidence within the context of an experimental asset market is investigated. Overall, 72 participants traded one risky asset on six markets of 12 participants each. The results indicate that individuals were not generally overconfident. Moreover, overconfidence was...

Why the rich are nastier than the poor : a note on optimal punishment

Huck, Steffen; Müller, Wieland - 1998

Studying evolutionarily successful behavior we show in a general framework that when individuals maximizing payoff differentials invest resources in punishing others. Interestingly, these investments are increasing in individuals, own wealth and decreasing in the wealth of others.

The relevance of equal splits : on a behavioral discontinuity in ultimatum games

Güth, Werner; Huck, Steffen; Müller, Wieland - 1998

The findings on the ultimatum game are considered as belonging to the most robust experimental results. In this paper we present a slightly altered version of the mini ultimatum game of Bolton and Zwick (1995). Whereas in the latter exactly equal splits were feasible in our games these were...

Evolutionary dynamics on infinite strategy spaces

Oechssler, Joerg; Riedel, Frank - 1998

The study of evolutionary dynamics was so far mainly restricted to finite strategy spaces. In this paper we show that … are well defined for infinite strategy spaces. Furthermore, we provide conditions for the stability of rest points … Bertrand oligopoly games, and mixed strategies. -- replicator dynamics ; evolutionary stability ; continuous strategy spaces …

Species survival and evolutionary stability in sustainable habitats : the concept of ecological stability

Aumann, Robert J.; Güth, Werner - 1998 - Rev.

Whoever exists belongs to a species, which did not become extinct, has a (geno-) type, which should be well adjusted, and lives in a habitat which has been sustainable for a long time. To capture the first aspect we allow for interspecies competition and analyze the conditions for species...
