Beauty, Productivity, and Discrimination: Lawyers' Looks and Lucre
利用一所法学院毕业生的纵向数据，通过入学照片评分衡量美貌，发现1970年代毕业的律师中，外貌更佳者在执业五年后收入更高，且该效应随经验增长；私营部门律师比公共部门更漂亮，差异随年龄增大，支持动态分类和客户行为理论。
The authors propose models with an ascriptive characteristic generating earnings differentials and causing sectoral sorting, allowing them to distinguish among sources producing such differentials. They use longitudinal data on a large sample of graduates from one law school and measure beauty by rating matriculation photographs. Better-looking attorneys who graduated in the 1970s earned more than others after five years of practice, an effect that grew with experience. Attorneys in the private sector are better-looking than those in the public sector, differences that rise with age. These results support theories of dynamic sorting and customer behavior.
