The evolution of fairness under an assortative matching rule in the ultimatum game
نویسنده
چکیده
This paper studies how a matching rule affects the evolution of fairness in an ultimatum mini game. Gale et al. [1995] show that only selfish behaviour survives in the deterministic replicator dynamics under the random matching rule. In contrast, this paper shows that, under an assortative matching rule, the fair behaviour may survive at an asymptotically stable state.

متن کاملThe Evolution of Fairness under Assortative Matching in Ultimatum Mini Game
This paper shows that, under assortative matching rule, the fair action can be maintained in ultimatum mini game on the evolutionary dynamics. If matching is random, then the selfish action generates higher payoff than fair action and the selfish individuals, who play rationally, are always survived on the replicator dynamics. If, however, matching is assortative, then fair responders are easy ...

This paper studies how amatching rule affects the evolution of fairness in the ultimatumgame. Gale et al. [1995] show that under the randommatching rule, a partially fair imperfect Nash equilibrium in which all proposers are fair but some responders are selfish is asymptotically stable in the limit as noise in learning vanishes if responders are noisier than proposers. This paper shows that, un...
متن کاملSocial Preference, Incomplete Information, and the Evolution of Ultimatum Game in the Small World Networks: An Agent-Based Approach
Certain social preference models have been proposed to explain fairness behavior in experimental games. Existing bodies of research on evolutionary games, however, explain the evolution of fairness merely through the self-interest agents. This paper attempts to analyze the ultimatum game's evolution on complex networks when a number of agents display social preference. Agents' social preference...
متن کاملFairness versus reason in the ultimatum game.
In the Ultimatum Game, two players are offered a chance to win a certain sum of money. All they must do is divide it. The proposer suggests how to split the sum. The responder can accept or reject the deal. If the deal is rejected, neither player gets anything. The rational solution, suggested by game theory, is for the proposer to offer the smallest possible share and for the responder to acce...
