在偏好为准线性的公共决策问题中，关键机制是防策略（需求揭示）。此外，没有代理人有动机通过退出委员会和消费剩余代理人做出的任何决定来“搭便车”。关键机制具有防策略性和不搭便车的特点。该机制是匿名和中立的。然而，战略防御性、安全性和中立性并不能共同成为它的特征，但是，如果对最终效用施加合理的下限（或上限），它们就会成为特征。我们的关键机制的最后一个特征使用了无搭便车公理和两个温和的单调性属性，但不是策略性。
The pivotal mechanism is strategyproof (demand revealing) in public decision problems where preferences are quasi-linear. Moreover, no agent has an incentive to “free ride” by withdrawing from the committee and consuming whatever decision is taken by the remaining agents. Strategyproofness plus No Free Ride characterize the pivotal mechanism. This mechanism is anonymous and neutral. Yet together Strategyproofness, Anonymity and Neutrality donotcharacterize it. They will, however, if reasonable lower (or upper) bounds on final utilities are imposed. Our last characterization of the pivotal mechanism uses the No Free Ride axiom and two mild monotonicity properties, but not Strategyproofness.
