中文摘要
我们使用一个新构建的准穷尽匹配雇主-雇员数据库来研究企业对法国工资不平等的贡献。我们对有限流动偏误实施了一个简单且易于处理的修正。我们的分析涵盖了 2002-2019 年，揭示了企业间不平等的加剧，这主要归因于具有相似市场价值的工人日益聚类。这些现象与企业层面不断增加的职业专门化相关联。我们的结果强调了经过偏误修正的 Abowd, Kramarz et Margolis (1999) 模型（下称 AKM）的估计值在刻画工资不平等动态演变中的重要性，并展示了可观测的职业类型和不可观测的个体特征如何共同促成了这些模式。
Abstract
We use a newly constructed and quasi-exhaustive matched employer-employee database to study the contribution of firms to wage inequality in France. We implement a simple and tractable correction for the limited mobility bias. Our analysis, covering the period 2002-2019, reveals an increase in between-firm inequality, mainly due to the growing clustering of workers with similar market value. These phenomena are associated with increasing occupational specialization at the firm level. Our results highlight the importance of bias-corrected AKM estimates of the Abowd, Kramarz et Margolis (1999) model-hereafter AKM-in capturing the dynamics of wage inequality, and show how both observable job types and unobservable individual characteristics contribute to these patterns.
