Commonality of information and commonality of beliefs
研究一组拥有共同先验的代理人随时间重复接收信号时，信号相关性如何影响信念的共同性，发现长期中条件独立信号可能比相关信号带来更大的信念共同性。
A group of agents with a common prior receive informative signals about an unknown state repeatedly over time. If these signals were public, agents' beliefs would be identical and commonly known. This suggests that if signals were private, then the more correlated they are, the greater is the commonality of beliefs. We show that, in fact, the opposite may be true. In the long run, conditionally independent signals may achieve greater commonality of beliefs than correlated signals.
