The main results of our indirect evolutionary approach to trust in large interactions suggest that trsutworthiness must be detectable if good conduct in trust-relationships is to survive. According to theoretical reasoning there is a niche then for an organization offering a possibly costly...

Norms play an important role in establishing social order. Thecurrent literature focuses on the emergence, maintenance and impactof norms with regard to coordination and cooperation. However, theissue of norm-related conict deserves more attention. We develop ageneral theory of \normative...

In this paper, we study a voluntary contribution mechanism withone-way communication. The relevance of one person’s words is assessedby assigning exogeniously the role of the ‘communicator’ to onegroup member. Contrary to the view that the mutual exchange ofpromises is necessary for the...

In this paper, we introduce the concept of payoff distortion inthe standard prisoner’s dilemma game when strategies are driven by psychologicalbehaviors. This concept enables to take account each player’s assessmentof the other player’s behavior and the asymmetry of information....

Why is it that well-intentioned actions can create persistent conflicts? While norms are widely regarded as a source for cooperation,this article proposes a novel theory in which the emergence of normscan be understood as a bargaining process in which normative conflicts explain the nally...

We analyze the effects of asymmetric information concerning thesize of a pie on proposer behavior in three different bargaining situations:the ultimatum game, the Yes-No-game and the dictator game.Our data show that (a) irrespective of the information condition, proposergenerosity increases with...

We examine experimentally two different types of trust: trust in another party's cooperation and trust in ability. In the cooperation condition, player A sends x{0,X} to player B. The amount x is multiplied by c=3, and B can return y{0,3x}. IN teh ability conditions, c depends on B's performance...

A cyclical network of indirect reciprocity is derived organizing 3- or6-person groups into rings of social interaction where the first individualcan help the second, the second the third, and so on till the last, who inreturn can help the first. Mutual cooperation is triggered by assuming...

We report on a research program that employs the indirect evolutionary approach to analyze how the institutional environment drives the evolution of trust and trustworthiness through the evolution of moral preferences, and how in turn the evolution of preferences shapes the evolution of the...
