Published in 1838, 'Recherches sur les Principes Mathématiques de la Théorie des Richesses' (Researches into the Mathematical Principles of the Theory of Wealth) is a seminal work by Antoine Augustin Cournot. This book pioneered the application of mathematics to economic analysis, introducing the use of functions and probability. It was the first text to formulate and graphically represent supply and demand as functions of price and introduced the foundational model of duopoly competition.

Antoine Augustin Cournot (1801-1877) was a French philosopher, mathematician, and economist who is considered a pioneer of mathematical economics. [11, 15] His 1838 book, 'Researches into the Mathematical Principles of the Theory of Wealth', introduced the use of functions and probability in economic analysis. In this work, he was the first to formulate and graphically represent supply and demand as a function of price, predating Alfred Marshall's work on the subject by decades. [15] His model of duopoly introduced concepts that are now known as the Nash equilibrium and reaction functions. [15]

Recherches sur les Principes Mathématiques de la Théorie des Richesses (1838)

Antoine Augustin Cournot was a pioneer in applying mathematical tools to economic analysis. Through his work, particularly his 1838 book, he introduced the use of functions, probability, and graphical representations to model economic concepts like supply, demand, and firm competition. This mathematical approach brought a new level of precision and rigor to the field, laying the groundwork for modern economic modeling.
