ABSTRACT
I recall that in the1970s, the keen interest in the theory of price and production that had dominated the1920–30s had decreased drastically. J. von Neumann, A. Wald, R. Remak, G. von Cassel, H. F. von Stackelberg, E. Schneider, P. A. Samuelson, and many other great authors developed their own theories of price and production in mathematically rigorous form. These unique contributions motivated many scientists to study economics, which led to the growth of mathematical economics in the mid-1950s. The existence and stability proofs of general equilibrium were thus achieved with remarkable mathematical precision. However, in the 1970s, many books on production and distribution were no longer being sold in bookstores. To my understanding, the state of the shops reflected the metamorphosis of the fundamental business activities in the advanced countries of the last century. The banking business and advanced industries began to computerize their activities. 1
