Over-education, Adverse Selection and System Innovation under Asymmetric Information

Over-education refers to the phenomenon that actual level of the individual education exceeds that of job requirement. It is universal in both developing countries and developed countries. The paper explores its causes, effects and the problem of consequent adverse selection in the view of asymmetric information. Moreover, it concludes that proper system innovation can reduce negative effects of over-education.
