Outline of Final Research Achievements	Based on Japan Household Panel Survey (JHPS), we measure to what extent healthcare inequality is affected by self-pay ratio and business cycles in Japan. Sakoda, Tamura, and Wakutsu(2022) measures healthcare inequality of Japan in 2008-2018. It shows that in the financial crisis, not only low-income class but also middle income class reduced the healthcare expenditures below their needs, and healthcare inequality was widened.
Academic Significance and Societal Importance of the Research Achievements	本研究課題で、医療格差とその推移についてパネルデータを用いて測定を行ったが、国民皆保険の下でも医療費支出は不況の影響を強く受けること、また世代ごとにその影響は異なることが分かった。これらの結果は医療政策を実施する上で考慮に入れるべきエビデンスの一つとして社会的・学術的意義がある。
