Abstract

How does the generosity of social insurance coverage affect demand for healthcare and health outcomes for the elderly? This paper examines the effect of insurance coverage on long-term care utilization and its health consequences using novel administrative data from the public long-term care insurance (LTCI) system in Japan. LTCI coverage is determined through a standardized health index and there exist multiple thresholds which generate discontinuous changes in the insurance coverage. Exploiting a regression discontinuity (RD) design, I find that an expansion of insurance coverage significantly increases recipients' long-term care utilization even without a change in price they face. I also find that utilizing more long-term care has little effect on health outcomes. Together, these results suggest that generous insurance coverage could induce excessive utilization mainly due to behavioral biases without having health benefits.
