GENDER DISCRIMINATION ESTIMATION IN A SEARCH MODEL WITH MATCHING AND BARGAINING*
构建了一个包含匹配、讨价还价和雇主偏好歧视的劳动力市场搜索模型，利用CPS数据估计发现半数雇主存在偏见，女性生产率平均低6.5%，三分之二的性别收入差距可由偏见解释，并模拟了平权行动政策的福利再分配效应。
This article develops a search model of the labor market with matching, bargaining, and employers' taste discrimination in which—under necessary but standard distributional assumption—it is possible to separately identify gender discrimination and unobserved productivity differences. The equilibrium shows that both prejudiced and unprejudiced employers wage discriminate. Maximum likelihood estimates on CPS data indicate that half of the employers are prejudiced, average female productivity is 6.5% lower, and two‐third of the gender earning differential may be explained by prejudice. An affirmative action policy is implemented resulting in a redistribution of welfare from men to women at no cost for employers' welfare.
