Outline of Final Research Achievements

This study attempted to measure the economic benefits of education, which are sought as lifetime income, along the career paths of individuals. Previous studies have used cross-sectional data to understand the economic benefits of education at a single point in time. This study estimated the economic benefits of education based on birth cohorts by converting cross-sectional survey data conducted at the same interval into pseudo-panel data. Cross-sectional data show changes in the economic benefits of education. However, using a pseudo-panel, we find that cohort offsets the period effect, and the economic benefits of education are estimated to be fairly equalized for cohorts born in the 1950s and 1960s.

Academic Significance and Societal Importance of the Research Achievements

これまで日本では個人の所得経歴データは存在しないため、個人の所得経歴に基づく学歴の経済的効用を検討することはできなかったが、クロスセクショナルなデータを加工することにより、新たな知見が提供でした。疑似パネルを用いた手法は、日本でも行われている例が見られるが、所得について援用した研究はみられず、これまでの学歴の経済的効用を異なる視点から理解する基盤を提供できた。
