Performance Pay and the White-Black Wage Gap
研究发现绩效薪酬加剧了高收入白人男性与黑人男性的工资差距，而这一差距在非绩效薪酬工作中反而缩小，即使控制可观测特征后依然成立。
We show that the reported tendency for performance pay to be associated with greater wage inequality at the top of the earnings distribution applies only to white workers. This results in the white-black wage differential among those in performance pay jobs growing over the earnings distribution even as the same differential shrinks over the distribution for those not in performance pay jobs. We show that this remains true even when examining suitable counterfactuals that hold observables constant between whites and blacks. We explore reasons behind our finding focusing on the interactions between discrimination, unmeasured ability, and selection.
