Optimal Quotas in Private Committees
传统观点认为提高投票配额会导致委员会维持现状或无效，但本文发现当委员秘密投票时，提高配额反而可能打破现状并促使新决策，降低配额则可能改善委员会表现。
According to conventional wisdom, raising the quota either causes a committee to retain the status quo or has no effect on its performance; so a committee which would otherwise select good decisions should operate with a low quota. We show that conventional wisdom may fail when members vote in private: raising the quota may prevent such a committee from retaining the status quo, and can cause it to switch between new decisions. Nevertheless, reducing the quota may improve a private committee's performance.
