具有可交换配置的机制设计

Mechanism Design with Exchangeable Allocations

Qiang Zhang

摘要:

我们研究了当代理人有不同类型的偏好时,无报酬的机制设计。相反,在大多数设置在文献中的代理人有相同的偏好,例如,在设施的位置游戏中,所有的代理人都想留在靠近(或远离)的设施,我们证明了机制设计的限制,当代理人有不同的偏好,通过引入交换阶段。我们考虑两种类型的交换阶段。第一种模式称为中央交换,其中交换由中央机构执行。另一种模式被称为个体交换,其中代理人自己交换他们的结果。以设施选址博弈为例,我们提供了一个真实的机制,优化社会福利在中央交换。我们还提供了一个普遍真实的随机机制,在个人交换中实现至少一半的最优社会福利。

英文摘要:

We investigate mechanism design without payments when agents have different types of preferences. Contrary to most settings in the literature where agents have the same preference, e.g. in the facility location games all agents would like to stay close to (or away from) the facility, we demonstrate the limitation of mechanism design without payments when agents have different preferences by introducing exchanging phases. We consider two types of exchanging phases. The first model is called central exchanges where the exchanges are performed by a central authority. The other model is called individual exchanges where agents exchange their outcomes by themselves. By using facility location games as an example, we provide a truthful mechanism that optimizes social welfare in central exchanges. We also provide a universally truthful randomized mechanism that achieves at least a half of the optimal social welfare in individual exchanges.
