Imperfect Competition, Compensating Differentials, and Rent Sharing in the US Labor Market
利用2001-2015年美国企业和工人税务记录构建雇主-雇员匹配面板数据，估计不完全竞争下企业和工人获得的劳动力市场租金规模，并分析工人异质性偏好对工资和就业的影响。
We quantify the importance of imperfect competition in the US labor market by estimating the size of labor market rents earned by American firms and workers. We construct a matched employer-employee panel dataset by combining the universe of US business and worker tax records for the period 2001–2015. Using this panel data, we identify and estimate an equilibrium model of the labor market with two-sided heterogeneity where workers view firms as imperfect substitutes because of heterogeneous preferences over nonwage job characteristics. The model allows us to draw inference about imperfect competition, worker sorting, compensating differentials, and rent sharing.
