Statistical Discrimination and the Early Career Evolution of the Black- White Wage Gap
构建并检验了一个统计歧视的动态模型，利用美国青年纵向调查数据发现，黑人和白人在进入劳动力市场时工资无差异，但随着经验积累差距扩大，主要原因是黑人从工作流动中获益较少。
This article develops and tests a simple dynamic model of statistical discrimination. The model improves on earlier static models both by allowing ex ante uncertainty about worker productivity to be resolved as on-the-job performance is observed and by generating several testable empirical implications. These predictions are tested using a sample of young men from the National Longitudinal Survey of Youth, producing mixed evidence for the model. The main empirical result is that no black-white wage gap exists at labor-force entry but that one develops as experience accumulates, mainly because blacks reap smaller gains from job mobility.
