Definition
Masahiko Aoki (1937 – 2015) was a Japanese economist renowned for his work in comparative institutional analysis, corporate governance, and the theory of the firm. He served as a professor at the University of Tokyo, Stanford University, and the University of California, Berkeley, among other institutions.
Overview
Born in Osaka, Japan, Aoki earned his undergraduate degree in economics from the University of Tokyo in 1960 and completed his Ph.D. in economics at the University of Chicago in 1964 under the supervision of Nobel laureate Milton Friedman. He held faculty positions at the University of Tokyo (1965–1975), Stanford Graduate School of Business (1975–1991), and the Graduate School of Business at the University of California, Berkeley (1991–2007), after which he returned to Japan as a professor emeritus at the University of Tokyo.
Aoki’s scholarly contributions span comparative institutional economics, transaction cost economics, and the study of corporate structures across different legal and cultural environments. He authored several influential books, including The Comparative Institutional Analysis of Business Systems (1990) and Information, Knowledge, and the Firm (1995). His research emphasized how institutional frameworks shape economic behavior and organizational forms.
Aoki was elected a foreign associate of the United States National Academy of Sciences and received numerous honors, such as the Order of the Sacred Treasure (Gold and Silver Star) from the Japanese government. He passed away on October 23, 2015, in Tokyo.
Etymology/Origin
The name “Masahiko” (正彦) combines the kanji 正 (masa), meaning “correct” or “right,” and 彦 (hiko), meaning “boy” or “prince.” The surname “Aoki” (青木) consists of 青 (ao), meaning “blue” or “green,” and 木 (ki), meaning “tree.” These characters are common in Japanese naming conventions and do not bear specific scholarly significance beyond personal identification.
