Stable matching in large markets with occupational choice
研究了个体可自主选择市场角色的多对多匹配模型，证明在温和条件下稳定匹配存在，可用于解释企业规模分布和工资不平等。
We introduce a model of large many‐to‐one matching markets with occupational choice where each individual can choose which side of the market to belong to. We show that stable matchings exist under mild assumptions; in particular, both complementarities and externalities can be accommodated. Our model generalizes Greinecker and Kah (2021), which focuses on one‐to‐one matching and did not allow for occupational choice. Applications include the roommate problem with nonatomic participants, explaining the size and distribution of firms and wage inequality.
