A Users’ Guide to Uncovering Worker and Firm Effects: The ABC of AKM
介绍AKM模型及其估计方法，讨论最佳实践，并综述工人与企业异质性对工资差异作用的实证发现，适合劳动经济学研究者快速了解该模型的应用与局限。
The AKM model introduced by Abowd, Kramarz, and Margolis (1999) has become a workhorse to study worker and firm heterogeneity, and to understand the sources of wage dispersion in the labor market using linked employer-employee data. In this article, we introduce the model and estimator, discuss some best practices for estimation, and review some empirical findings on the role of worker and firm heterogeneity in wage dispersion. While the AKM methodology has proven useful to analyze a host of questions in a variety of settings within labor economics and beyond, we also point to the need for methodological developments.
