重复匹配市场的稳定性

Stability in Repeated Matching Markets

Ce Liu

摘要:

本文提出了一个重复匹配市场的框架。该模型与Gale-Shapley匹配模型不同,在每个时期都有一组固定的长寿医院与新一代的短命居民相匹配。我表明,有两种医院在这种重复的环境中:一些医院可以动态地主动减少他们的招聘能力,潜在地使更多的居民提供给农村医院;然而,其他的,是不可接触的,即使与重复的互动,必须获得相同的匹配,因为他们在一个静态匹配。在具有相关偏好的大型匹配市场中,最多只有一小部分医院是不可触及的。绝大多数医院都可以通过动态激励来激励。

英文摘要:

This paper develops a framework for repeated matching markets. The model departs from the Gale-Shapley matching model by having a fixed set of long-lived hospitals match with a new generation of short-lived residents in every period. I show that there are two kinds of hospitals in this repeated environment: some hospitals can be motivated dynamically to voluntarily reduce their hiring capacity, potentially making more residents available to rural hospitals; the others, however, are untouchable even with repeated interaction and must obtain the same match as they do in a static matching. In large matching markets with correlated preferences, at most a vanishingly small fraction of the hospitals are untouchable. The vast majority of hospitals can be motivated using dynamic incentives.
