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...

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 this restriction is in most cases unnecessary. We give a mild condition under which the continuous time replicator dynamics are well defined for infinite strategy spaces....

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 …

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...

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...

Scale economies and the dynamics of recurring auctions

Jeitschko, Thomas D.; Wolfstetter, Elmar - 1998

We analyze the dynamics of a game of sequential bidding in the presence of stochastic scale effects in the form of stochastic economies or diseconomies of scale. We show that economies give rise to declining expected equilibrium prices, whereas the converse is not generally true. Moreover,...

Do banks crowd in or out business ethics? : an indirect evolutionary analysis

Güth, Werner - 1998 - Rev.

The evolution of trustworthiness as a major aspect of business ethics depends crucially on whether it can be signaled. If this is impossible, only opportunistic traders will survive. Whereas previous studies have analysed detection agencies (Güth and Kliemt, 1994 and 1998) or have substituted...

Will banks promote trade? : equilibrium selection for the trust game with banks

Güth, Werner; Ockenfels, Peter - 1998 - Rev.

The Trust Game describes a situation where mutually beneficial trade is endangered by opportunistic exploitation. In the Trust Game with Banks this dilemma can be avoided by banks guaranteeing that sellers will be paid. This outcome is, however, not the only possible solution. Bank interference...
