(Antoine Augustin) Cournot / Ichiro Nakayama Price: ¥660 + tax (¥726) 8th printing, February 2011 A highly original work by Cournot (1801-1877), the founder of modern economics, especially mathematical economics, who clarified demand, monopoly, free competition, etc. In particular, his theory of monopoly pricing is the main subject of this book, and the brilliance of the process of steadily and rigorously building the theory from one extreme to the other, with monopoly as one extreme and free competition as the other, is truly a display of his full potential. Antoine Augustin Cournot (August 28, 1801 – March 31, 1877) French philosopher and mathematician. He is considered the founder of mathematical economics, who developed theories of duopoly and supply and demand using mathematical models half a century before the "Marginal Revolution." In a duopoly industry with only two companies, the "Cournot duopoly model" is a model in which each company determines its own supply (output) under the assumption that the rival company's supply (output) does not change. In other words, in a duopoly situation, there can be strategic interdependence in which the other company changes its output depending on the output the one company chooses. However, assuming that the output of company 2 does not change due to the change in the output of company 1, there is no incentive for either company to change its output. This point is called the "Cournot equilibrium." The point of maximum profit output and price for a monopoly company is called the "Cournot point." In the field of economics, he is best known for his research in the field of oligopoly theory (Cournot competition). ＊Mainly dealing with popular works and out-of-print paperback editions.
