AI总结:

本文研究了在信号成本下,非协调机制在提高社会福利方面的优势,并证明其可通过粗等级竞赛实现。

摘要:

我们研究了一种利用 costly signaling 作为筛选工具的分配机制。社会规划者旨在最大化社会福利,定义为代理人的效用加权和,同时实施特定的分配规则。在广泛的一类代理人偏好中,我们证明协调机制(推荐信号取决于联合报告)可以被非协调机制(信号仅取决于个体报告)所超越。我们正式化了最优机制不具有协调性的条件,并证明此类机制可通过粗等级竞赛实现。

英文摘要:

We study allocation mechanisms that utilize costly signaling as a screening tool. A social planner aims to maximize social welfare, defined as the weighted sum of agents' utilities, while implementing a specific allocation rule. Within a broad class of agent preferences, we show that coordination mechanisms (where recommended signals depend on joint reports) are outperformed by non-coordination mechanisms (where signals depend solely on individual reports). When agents are also symmetric, such mechanisms are implementable through coarse-ranking contests.
