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.
