AI总结:
本文提出两种机制设计,确保多数偏好选项在所有均衡中胜出,克服多数规则实施的不可能性,并提高投票效率,同时利用非均衡抽签激励诚实投票,并探讨弃权等扩展。
摘要:
我们设计了两种机制,确保在所有均衡中,多数偏好的选项都能胜出。第一种是同时博弈,其中代理人在投票选择替代方案之外,还选择其他代理人进行合作,从而克服了近期关于多数规则实施的不可能性结果。第二种机制在标准多数投票程序中增加了顺序批准,使得在显著少于广泛使用的点名投票的步骤中达到(正确的)结果。两种机制都利用非均衡抽签来激励诚实投票。我们讨论了不同的扩展,包括代理人弃权(不执行)的可能性。
英文摘要:
We design two mechanisms that ensure that the majority preferred option wins in all equilibria. The first one is a simultaneous game where agents choose other agents to cooperate with on top of the vote for an alternative, thus overcoming recent impossibility results concerning the implementation of majority rule. The second one adds sequential ratification to the standard majority voting procedure allowing to reach the (correct) outcome in significantly fewer steps than the widely used roll call voting. Both mechanisms use off-equilibrium lotteries to incentivize truthful voting. We discuss different extensions, including the possibility for agents to abstain.
