## Who is Antoine Augustin Cournot?

Antoine Augustin Cournot is known for his contributions to economic theories. His work, “Researches into the Mathematical Principles of Wealth,” holds an important place in the history of economic thought. This work introduced the idea that economic data could be analysed through mathematical models, and it is considered as a tool on which microeconomic theory is based.

He also contributed to the mathematical modelling of production functions by comparing inputs and outputs in a specific economic system. He received his education at Collège de Gray from 1809-1816 and completed his university education at École Normale Supérieur. As his vision deteriorated over the years, Cournot took a one-year leave of absence in 1844 and visited Italy.

Upon his return from Italy, he resumed his duties but had to give up his mathematical research. In 1847, he published a book on algebra and geometry. He declined an offer to be the rector of the Toulouse Academy in 1854, but accepted the rectorship of the Dijon Academy and retired to Paris after his retirement.

Antoine Augustin Cournot’s ideas have paved the way for the development of modern economic theories, and he is regarded as one of the prominent figures of 19th-century French economic thought. His thoughts remain among the important tools in the discipline of economics and are still used in economic research and analysis. Cournot made significant contributions to the development of French economic thought and is remembered as a philosopher who shaped the framework of economic theories.

### His Works and Impact

While primarily a mathematician, Cournot’s impact is also felt in economics. His theories on monopolies and duopolies are still widely used today, and his book, “Researches on Mathematical Principles of the Theory of Wealth”, was published in 1838. Although it was criticized, it remains influential in economics and is seen by many economists as the starting point of modern economic analysis.

Antoine Augustin Cournot introduced functions, probability ideas, and the first formula of the supply-demand rule as a function of price into economic analysis. He was also the first person to graph supply and demand curves, predicting the work of Alfred Marshall thirty years before his time. He introduced concepts such as the Cournot duopoly model, Nash equilibrium, reaction functions, and best response dynamics.

Antoine Augustin Cournot argued that mathematics should only be used in economics to create limits and express uncertain realities in precise terms. He believed that the use of mathematics in economics did not provide exact numerical certainty.
