摘要

本文建立了一个研究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期参与者(企业)与新一代短期参与者(工人)匹配。我定义了这种重复匹配环境中的历史依赖和自我执行匹配过程,并描述了公司的收益。公司可以分为两类:一些公司必须获得与静态稳定匹配相同的收益,这在每个耐心水平上都成立;同时,如果企业有足够的耐心,重复和历史依赖可以扩大其他企业的可持续回报集。在具有相关偏好的大型匹配市场中,第一类公司对应的是最多只占市场一小部分的“精英”公司。绝大多数公司属于第二类。

Stability in repeated matching markets
This paper develops a framework for studying repeated matching markets. The model departs from the Gale–Shapley matching model by having a fixed set of long‐lived players (firms) match with a new generation of short‐lived players (workers) in every period. I define history‐dependent and self‐enforcing matching processes in this repeated matching environment and characterize the firms' payoffs. Firms fall into one of two categories: some firms must obtain the same payoff as they would in static stable matchings, and this holds at every patience level; meanwhile, repetition and history dependence can enlarge the set of sustainable payoffs for the other firms, provided that the firms are sufficiently patient. In large matching markets with correlated preferences, the first kind of firms corresponds to “elite” firms that make up at most a vanishingly small fraction of the market. The vast majority of firms fall into the second category.
