'''Antoine Augustin Cournot''' (
28 August 1801‑
31 March 1877) was a
French people French philosopher and
mathematician.
Antoine Augustin Cournot was born at Gray,
Haute-Saone. In
1821 he entered a teachers’ training college, and in 1829 he had earned a doctoral degree in mathematics, with mechanics as his main thesis supplemented by astrology. After graduating, Cournot held many positions as professor of analysis and mechanics, chief examiner for undergraduate students, and rector of
Dijon Academy.
Cournot was mainly a mathematician, but did have some influence over economics. His theories on
monopoly monopolies and
duopoly duopolies are still famous. In 1838 the book ''Researches on the Mathematical Principals of the Theory of Wealth'' was published, in which he used the application of the formulas and symbols of mathematics in economic analysis. This book was highly criticized and not very successful during Cournot’s lifetime, and he did try to rewrite it twice, but it still has influence in economics today. Today many economists believe this book to be the point of departure for modern
economic analysis. Cournot introduced the ideas of
function (mathematics) functions and
probability into economic analysis. He derived the first formula for the rule of
supply and demand as a function of
price and in fact was the first to draw supply and demand curves on a graph, anticipating the work of
Alfred Marshall by roughly thirty years.
Cournot believed that economists must utilize the tools of mathematics only to establish probable limits and to express less stable facts in more absolute terms. He further held that the practical uses of mathematics in economics do not necessarily involve strict numerical precision.
Today, Cournot’s work is recognized in a discipline called
econometrics. He was also a teacher of
political economy and mathematics to
Auguste Walras, who was the father of
Leon Walras. Cournot and Auguste Walras persuaded Leon Walras to try political economics. Cournot is also credited to be one of the sources of inspiration for Leon Walras and his equilibrium theory.
By the time Cournot died in 1877, he was nearly blind.
In the field of
economics he is best known for his work in the field of
oligopoly theory -
