Discrimination and Skill Differences in an Equilibrium Search Model*
构建均衡搜寻模型，分析具有相同人力资本但种族不同的工人之间工资和失业差异的三个来源：未观测生产率、搜寻强度以及基于雇主厌恶因素的歧视。利用劳动力市场调查数据估计结构参数，发现黑人生产率比白人低3.3%，雇主厌恶因素占白人生产率的31%，56%的企业对黑人有厌恶因素。
We analyze an equilibrium search model with three sources for wage and unemployment differentials among workers with the same (observed) human capital but different appearance (race): unobserved productivity, search intensities, and discrimination due to an appearance‐based employer disutility factor. We show that the structural parameters are identified using labor market survey data. Estimation results for a black and white high school graduate sample imply: black productivity is 3.3% lower than white productivity; the employer's disutility factor is 31% of the white's productivity level; and 56% of firms have a disutility factor toward blacks.
