WebIn a celebrated paper, Aumann (1976) established the Agreement Theorem: if two agents have the same prior belief over possible states of the world, and if their posteriors for an event are commonly known by both, then these posteriors must be equal. In this sense, agents cannot agree to disagree.1 WebAumann used this definition to state and prove a theorem asserting that two experts cannot "agree to disagree." THEOREM 1: Suppose that for some event B and some to it is common knowledge at to that p(Bj?P) = a and p(Bj.2) = ,3. Then a =,3. Thus, when two experts have identical prior beliefs and each obtains some private
