Comportements adaptatifs sans croyances

Abstract : HAL : ujm-00121796, version 1 (mot de passe=a0m?rwce) n this paper, we consider situations where agents face repeatedly the same decision problem. We focus on adaptive rules without beliefs. We distinguish between two kinds of models. Firstly, we study adaptive rules that are only based on private information. Decisions are made on the basis of past payoffs. Moreover, some of these models incorporate an aspiration level : the agent compares the payoff which he receives to this aspiration level. Secondly, we present adaptive rules that take into account information about other agents. Each agent observes the actions of others and makes a decision via imitation. Various imitations rules are investigated and discussed.Adaptation, renforcement, seuil d'aspiration, imitation
