Productivity or Discrimination? Beauty and the Exams*
研究美貌对收入的影响是源于歧视还是生产力，通过考试数据发现支持生产力相关的歧视，而非基于偏好的贝克尔式歧视。
Do good looks make people more productive? An impact of looks on earnings has been found in the empirical literature: plain people earn less than average-looking people who earn less than the good-looking. However, an important question remains unanswered: is the impact of beauty due to pure discrimination or productivity? We provide evidence against the hypothesis of Becker-type discrimination stemming from tastes and in favor of productivity-related discrimination.
