Will Affirmative Action Policies Eliminate Negative Stereotypes
研究平权政策如何影响雇主对少数族裔工人生产力的信念，证明即使群体先天禀赋相同，政策也可能导致雇主事后正确感知到群体生产力差异。
A key question concerning affirmative action is whether the labor-market gains it brings to minorities can continue without it becoming a permanent fixture in the labor market. The authors argue that this depends on how the policy affects employers' beliefs about the productivity of minority workers. They study the joint determination of employer beliefs and worker productivity in a model of statistical discrimination in job assignments. The authors prove that, even when identifiable groups are equally endowed ex ante, affirmative action can bring about a situation in which employers (correctly) perceive the groups to be unequally productive, ex post.
