Abstract

This study empirically tests the effects of the introduction of copayments on healthcare utilization in the Korea’s medical aid program (MAP). Due to a growing concern about overutilization of public healthcare and government’s financial burden, the Korean government reformed the MAP in 2007 and introduced copayments for outpatient care of Type 1 enrollees who had borne no medical treatment cost until the reform. Exploiting the natural experiment of 2007 reform, we perform a difference-in-differences (DID) analysis with propensity score matching and conclude that the introduction of copayments reduces healthcare utilization in the short-run through heterogeneous effect on the outpatient services consumption distribution, but this effect rapidly disappears over time.
