Consensus, communication and knowledge: An extension with Bayesian agents

Contents:

Author Info

  • Menager, Lucie

Abstract

We extend the result of Parikh and Krasucki [1990] to the case where the set of available decisions is arbitrary. We show that if agents are bayesian and choose the action that maximizes their expected utility, then word of mouth communication leads to the equality of all decisions.
