معرفی
Manabu Toda is a Professor at the Faculty of Social Sciences, School of Social Sciences at Waseda University, where he has been teaching since 2000 (previously as Associate Professor). He holds a Ph.D. in Economics from the University of Rochester and specializes in Economic Theory, Game Theory, and Matching Theory. His academic career spans multiple institutions including Waseda University, Tokyo Keizai University, and affiliations with the Graduate Schools of Economics, Social Sciences, and Creative Science and Engineering at Waseda.
Professor Toda's educational background includes:
- Ph.D. in Economics from the University of Rochester (1983-1988)
- Graduate studies in Economic Theory at Hitotsubashi University (1980-1989)
- Bachelor's degree in Economics from St. Paul's University (1976-1980)
Professor Toda's primary research interests focus on Economic Theory, particularly Game Theory and Matching Theory. His work explores the mathematical foundations of economic systems, with emphasis on stability, monotonicity, and consistency properties in matching markets. He has made significant contributions to the axiomatization of core solutions in various matching frameworks.
His research extends to Mechanism Design, Mathematical Economics, and General Equilibrium Theory, where he investigates the existence and properties of equilibrium solutions in both convex and non-convex economic models. Professor Toda's theoretical work has practical applications in market design problems, including the Japanese Resident Matching Program for physician placements.
Professor Toda's publication record demonstrates a consistent focus on matching theory and game-theoretic applications in economics. His most recent work (2024) continues his long-standing investigation into monotonicity properties and stability in one-to-one matching problems, building on decades of theoretical development. Throughout his career, he has systematically explored the core solution concept across various matching frameworks, establishing axiomatic characterizations that connect discrete matching markets with continuous assignment games.
His research trajectory shows a progression from foundational work on equilibrium existence in general economic models (1990s) to increasingly specialized contributions in matching theory (2000s-present). A notable pattern is his focus on consistency properties and their relationship with other solution concepts, which has provided important theoretical insights for market design applications, particularly in medical residency matching systems in Japan.
While specific awards are not detailed in the provided information, Professor Toda's research impact is evidenced by his substantial citation record: 168 citations on Scopus (h-index 5) and 428 citations on Google Scholar (h-index 8, i10-index 7). His work has been published in prestigious journals including Games and Economic Behavior, Journal of Economic Theory, and International Journal of Game Theory, indicating recognition by his peers in the field of economic theory.
Professor Toda has supervised numerous graduate students through his teaching of advanced economics courses at Waseda University, including graduate-level Market Economy Theory. His research has been supported by multiple competitive grants from the Japan Society for the Promotion of Science, focusing on applications of game theory to environmental cooperation problems, cost allocation methods, and matching systems. Notably, his recent work (2019-2022) examined regional disparities in physician clinical training matching in Japan, combining theoretical analysis with empirical investigation to improve rural healthcare services.
Professor Toda collaborates with researchers across Waseda University, including colleagues in the Faculty of Political Science and Economics and the Faculty of Science and Engineering. His recent work on physician matching involved collaboration with Yoichi Kasajima, as evidenced by their co-authored 2024 paper. He has also worked with Toshiaki Suematsu and Sumihiko Ohira on environmental cooperation problems. Professor Toda has hosted research meetings with young scholars in matching theory, fostering the next generation of researchers in this specialized field.
