ABSTRACT
This chapter concerns the international contributions by Japanese theoretical economists in the post-World War II period. Kei Shibata and Masazo Sono are two such exceptional Japanese scholars who were able to add something new to modern economic theory of that period. Takuma Yasui began to study Walrasian general equilibrium theory during World War II. But he was frustrated because he could not find the correct method to deal with the dynamic analysis of Walras tatonnement process of price adjustment. Michio Morishima was a distinguished Japanese mathematical economist, although he was a Professor of the London School of Economics from 1970 to 1988. The output of joint research on mathematical programming with Kenneth Arrow and Leonid Hurwicz was published in Arrow, Hurwicz and Uzawa. The mathematical study of the classical and Marxian economic systems was begun in the early period of the twentieth century by a few economists such as Dmitriev and Bortkiewicz.
