With a career spanning several of the world's most prestigious academic institutions, Horioka has bridged the gap between theoretical macroeconomics and empirical reality, providing critical insights into how nations save, invest, and interact within the global market.

Academic Appointments and Leadership
Horioka currently holds a diverse portfolio of research and teaching roles across Japan. He serves as a Research Professor at the Center for Computational Social Science and a Research Fellow at the Research Institute for Economics and Business Administration at Kobe University. Additionally, he is the Director and Distinguished Research Professor at the Asian Growth Research Institute in Kitakyushu City, as well as a Professor Emeritus and Invited Professor at Osaka University's Institute of Social and Economic Research.
His previous teaching experience is equally distinguished, having held positions at Stanford, Columbia, Kyoto, and Osaka Universities, as well as the University of the Philippines, Diliman, where he served as the Vea Family Professor of Technology and Evolutionary Economics Centennial.
Beyond the classroom, Horioka has led several influential professional organizations. He served as President of the Society of Economics of the Household (SEHO) from 2021 to 2023 and President of the Japanese Economic Association from 2023 to 2024. He currently leads the International Association for Research on Income and Wealth (IARIW) as President for the 2024–26 term.
The Feldstein–Horioka Puzzle
Horioka is perhaps most widely recognized for his 1980 collaboration with Martin Feldstein. Their seminal paper, "Domestic Saving and International Capital Flows," published in the Economic Journal, identified a positive correlation between long-term savings and investment rates across different countries.
This finding created what is now known as the Feldstein–Horioka puzzle (or paradox). In a world of perfect capital mobility, one would expect a country's investment to be independent of its domestic savings; however, Horioka's work demonstrated a strong link, challenging existing assumptions in international finance. This article remains one of the most cited works in the field.
Research Specializations and Impact
While international finance is a cornerstone of his work, Horioka's expertise extends deeply into macroeconomics (the study of economy-wide phenomena) and household and family economics. He has conducted extensive research on consumption, saving, and bequest behavior, as well as the dynamics of parent-child relations.
His empirical studies cover a broad geographic range, focusing on the economies of Japan, the United States, China, India, Korea, and Asia more broadly. His commitment to the field is further evidenced by his editorial work; he co-edited the International Economic Review for 15 years (1998–2013) and currently co-edits the Review of Economics of the Household.
Horioka also maintains a strong connection to the United States as a Research Associate and Co-director of the Japan Project of the National Bureau of Economic Research (NBER) in Cambridge, Massachusetts.
