영문 초록

On March 11th, 2011, the Great East Japan Earthquake (GEJE) and massive tidal waves hit the approximately 400 kilometer-length of the Pacific coasts and wreaked devastating damage to residences and communal societies. Using the three waves of panel data from the Japan Study for Aging and Retirement (JSTAR) before and after the GEJE, we examine the effect of the catastrophic natural disaster in 2011 on health, using a Difference-in-Differences (DD) model and find significant negative impact on the afflicted people’s health. Considering a discontinuous decline in the copayment rate for medical care at age 70 in the Japanese public health insurance system, we further examine both the direct and indirect health effects through changing medical and long-term care utilization. We find that the GEJE disaster had a heavily negative impact on the afflicted people’s health and that their medical and long-term formal care utilization after the earthquake decreased their health deterioration. We also find that a discontinuous decline in the copayment rate for medical care at age 70 in the Japanese public health insurance system increases medical and long-term care utilization, and this copayment reduction increases long-term care utilization and also has positive effects on health in the long-term.
