Abstract/Summary Though the impact of co-payments on health care demand is well documented in developed countries, evidence from developing countries is rare. In this paper, we contribute to this scarcity by analysing the impact of increasing co-payments in a developing country, namely Vietnam. In 2007, the Vietnam government reintroduced a co-payment of 20 percent for individuals with voluntary health insurance. Because individuals with compulsory health insurance and the uninsured were exempted from the increase in co-payments, this policy can be regarded as a quasi-natural experiment. We use a difference-in-difference approach to examine whether the increase in co-payment effectively reduces the demand for health care services. We find it has no significant negative impact on health care demand. This finding holds with different control groups, outcomes and estimators.
