We study the set of possible joint posterior belief distributions of a group of agents who share a common prior regarding a binary state, and who observe some information structure. Our main result is that, for two agents, a quantitative version of Aumann's Agreement Theorem provides a necessary and sufficient condition for feasibility. For any ...
