Outline of Final Research Achievements	We developed a dynamic model that explicitly deals with the impact of intergenerational income transfers through private supplementary education on welfare, and theoretically clarified that whether schooling and private tutoring are substitutes or complements has different effects on educational stratification and human capital accumulation. Using data from the Family Income and Expenditure Survey and the National Survey of Family Income and Expenditure, which allow us to take into account the attributes of the households to which children belong, we empirically show that differences in the demand for private supplementary education differ by the number of children, educational stage, provider, and grade level of children.

Academic Significance and Societal Importance of the Research Achievements	本研究が取り組んだ理論実証分析は、学校外教育を起点とする教育格差の実態およびその厚生評価を、従前より体系的かつ精緻に行うことを可能にするとともに、長期継続的な個票データを用いることで、幼児や高校生への授業料無償化など、教育分野において進む自己負担軽減に対する政策的潮流への客観的評価に資する実証的な知見を提供しうる点に、学術的独自性と社会的意義を有するものと解せられる。
