Abstract: We estimate the longer-term impact of coinsurance for the elderly by RDD using administrative data, focusing on the increase in coinsurance in Japan, from 10% to 20%, for those aged 70-74, born after April 1944. The reduction of utilization in the longer term is similar to, or slightly larger than, in the short term. Patients reduce potentially wasteful care more; we do not find discernible impacts on health outcome and health-related behaviors. For the moderate change of prices for the elderly, distinctive characteristics associated with medical services, like behavioral hazard and ex-ante moral hazard, seem not largely affect consumer responsiveness.
