The Effect Of Statistical Discrimination On Black–White Wage Inequality: Estimating A Model With Multiple Equilibria*
对统计歧视模型进行结构估计，识别模型参数和均衡选择，发现美国工资不平等下降不能归因于均衡变化，但反事实实验表明色盲社会中黑人工资平均提高20%以上。
This article presents the structural estimation of the parameters of a statistical discrimination model. Although the model is capable of displaying multiple equilibria, an estimation strategy that identifies both the model parameters and the equilibrium selected by the economic agents is developed and empirically implemented. A comparison between the selected equilibria and the other potential equilibria reveals that the decline in wage inequality experienced in the U.S. economy cannot be attributed to changes in the equilibrium selection. Nonetheless, a counterfactual experiment shows that in a color‐blind society blacks' wage would have been on average more than 20% higher.
