Consensus, Communication and Knowledge : an Extension with Bayesian Agents
AbstractWe extend the result of Parikh and Krasucki  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.
