Endogenous Clustering and Analogy-Based Expectation Equilibrium.

Normal-form two-player games are categorized by players into K analogy classes so as to minimize the prediction error about the behaviour of the opponent. This results in Clustered Analogy-Based Expectation Equilibria in which strategies are analogy-based expectation equilibria given the analogy par...

      ab: Normal-form two-player games are categorized by players into K analogy classes so as to minimize the prediction error about the behaviour of the opponent. This results in Clustered Analogy-Based Expectation Equilibria in which strategies are analogy-based expectation equilibria given the analogy partitions and analogy partitions minimize the prediction errors given the strategies. We distinguish between environments with self-repelling analogy partitions in which some mixing over partitions is required and environments with self-attractive partitions in which several analogy partitions can arise, thereby suggesting new channels of belief heterogeneity and equilibrium multiplicity. Various economic applications are discussed.
