This paper empirically studies effects of the graduation quota system on wage differentials between college and high school graduates. We estimate a semiparamteric model that includes nonparametric interaction terms of cohort and education. Results show that (1) the significant drops in college premium occurred with a lag and lasted for the younger generation, and (2) underemployment of college graduates, decreased wage differentials of low-skilled jobs, and decreased skill premiums of high school graduates are the main causes of the drops in college premium. They suggest that the effects of the graduation quota system have centered around the low-waged workers.
