Axelrod Meets Cournot: Oligopoly and the Evolutionary Metaphor

  • Huw David Dixon

This paper explores the implication of evolutionary models (replicatordynamics) in a simple Cournot duopoly model. A firm type is a linear decisionrule in which the firm's output depends on the other firm's previous output.First we run an Axelrod Tournament between firm types. The champion firm isa near profit-maximizer. Secondly, we allow social evolution to occur usingreplicator dynamics. Here we find that there are very strong forces leadingtowards a collusive or near collusive outcome, so long as there is not toomuch `noise' in the dynamics.
