The aim of this paper is twofold. Starting from the population dynamics literature, which usually finds the resulting distribution of a trait in a population, according to some parents' preferences, I answer the inverted question: Which preference function would yield into a given trait...

A simple symmetric 2 "e 2 strategic coordination game is analyzed in an evolutionary environment under the assumption that agents are able to condition their actions on observations made of the opponent. Agents are assumed to be associated with a profile of characteristics, of which all agents...

We analyze a cooperation game in an evolutionary environment. Agents make noisy observations of opponents' propensity to cooperate, called reputation, and form preferences over opponents based on their reputation. A game takes place when two agents agree to play. Pareto optimal cooperation is...

In this article, we attempt to explain the fair outcome of ultimatum game experiments using the evolutionary dynamics. The players of the game, the proposers and the responders, are randomly matched to play the game. When the responders face low offers from the proposers, their decisions are...

Evolutionary dynamics in games imply de-facto spiteful behavior of the players: In order to 'survive' the evolutionary process, players must perform better than their opponents. This means they maximize relative rather than absolute payoffs. The paper shows that there is a class of games...
