Decomposing the Sources of Earnings Inequality: Assessing the Role of Reallocation
利用美国人口普查局的雇主-雇员匹配数据，研究了1992至2003年间工人和企业重新配置对行业内外收入不平等变化的贡献，发现企业进入退出和工人与企业匹配是重要因素，且行业间存在异质性。
This study exploits longitudinal employer–employee matched data from the U.S. Census Bureau to investigate the contribution of worker and firm reallocation to changes in earnings inequality within and across industries between 1992 and 2003. We find that factors that cannot be measured using standard cross‐sectional data, including the entry and exit of firms and the sorting of workers across firms, are important sources of changes in earnings distributions over time. Our results also suggest that the dynamics driving changes in earnings inequality are heterogeneous across industries.
