我们研究了纯交换经济中防策略和有效机制的可能性。Zhou（1991）在他著名的论文中建立了一个优雅的不可能性结果：在两个主体的情况下，不存在防策略的、有效的和非独裁的机制。他承认，在三个或更多代理人的情况下，不存在防策略的、有效的和“非逆独裁”的机制。然而，我们发现了一些反例，他的猜想的情况下，四个或更多的代理。我们提出了一个新的有趣的开放性问题：是否有任何防策略，有效的，和“非交替独裁”的机制？
We study the possibility of strategy-proof and efficient mechanisms in pure exchange economies. In his remarkable paper, Zhou (1991) establishes an elegant impossibility result: there is no strategy-proof, efficient, and non-dictatorial mechanism in the two-agent case. He conjectures that there is no strategy-proof, efficient, and “non-inversely-dictatorial” mechanism in the case of three or more agents. However, we discover some counterexamples to his conjecture in the case of four or more agents. We present a new interesting open question: Is there any strategy-proof, efficient, and “non-alternately-dictatorial” mechanism?
