Firms and Labor Market Inequality: Evidence and Some Theory
综合了两类关于企业层面工资不平等驱动因素的研究，发现租金分享弹性在0.05-0.15之间，企业特定溢价解释了20%的工资差异，并构建了一个模型来解释这些发现。
We synthesize two related literatures on firm-level drivers of wage inequality. Studies of rent sharing that use matched worker-firm data find elasticities of wages with respect to value added per worker in the range of 0.05–0.15. Studies of wage determination with worker and firm fixed effects typically find that firm-specific premiums explain 20% of overall wage variation. To interpret these findings, we develop a model of wage setting in which workers have idiosyncratic tastes for different workplaces. Simple versions of this model can rationalize standard fixed effects specifications and also match the typical rent-sharing elasticities in the literature.
