Prof Satoshi Araki has published an article "Reassessing human capital and health capital over the life course: Causal mediation analysis of higher education, health, and wages" in Social Science & Medicine (https://doi.org/10.1016/j.socscimed.2025.118299). In this paper, Prof Araki examines the economic value of education and health from the life course perspective, developing concepts of human capital and health capital. Leveraging causal mediation analysis and the recentred influence function, the study shows (1) the wage returns to college completion unmediated by health are substantial; (2) as people age, the mediating role of health rises despite its modest effect size; (3) the direct contribution of college completion is evident for upper wage quantiles; and (4) the indirect path via health buffers a risk of falling into low-middle wage strata. Based on these findings, Prof Araki argues that college completion as such demonstrates a boosting effect on higher wages throughout one's career, whereas the pathway along enhanced health serves as a protective factor against falling into lower wage strata later in life.
