WebA celebrated 1976 theorem of Aumann asserts that Bayesian agents with common priors can never “agree to disagree”: if their opinions about any topic are common knowledge, then those opinions must be equal. But two key questions went unaddressed: ﬁrst, can the agents reach agreement af-ter a conversation of reasonable length? Second, can the WebThe impossibility for two agents to agree to disagree is established by Aumann's so-called agreement theorem. More precisely, it is shown that if two Bayesian agents equipped …

WebAumann''s Agreement Theorem has given rise to a large literature which we review in this paper. The results are classified according to whether they are probabilistic (Bayesian) or qualitative. Particular attention is paid to the issue of how to interpret the notion of Harsanyi consistency as a (local) property of belief hierarchies.
