CNRS Delegation welcome of Juan Carvajalino at BETA (2025–2026)

From September 2025 to September 2026, BETA will have the pleasure of welcoming Juan Carvajalino, senior lecturer at Paris 8 University and member of the Laboratoire d’Économie Dionysien, as part of a CNRS delegation welcome.

A historian of economic thought and science, Juan Carvajalino studies the mathematisation of economics as an intellectual and institutional process. His work focuses on the intellectual history of formalisation in economics. He is currently Book Review Editor of History of Political Economy.

His research focuses on the relationships between economics, mathematics, and the social and natural sciences in the 20th century. In particular, he has analysed Foundations of Economic Analysis (Paul Samuelson, 1947), demonstrating its decisive role in the formation of American mathematical economics. He is currently conducting a study on Theory of Games and Economic Behaviour (John von Neumann and Oskar Morgenstern, 1944), devoted to the circulation of ideas between mathematics, economics and the social sciences.

Within BETA’s ‘Cliometrics and History of Economic Thought’ group, he will develop a comparative project on these two major works, aiming to shed light on their contrasting conceptions of mathematics: sometimes as the universal language of operational science, sometimes as an analytical and aesthetic form of knowledge.

In collaboration with members of BETA, he will also participate in projects on the legacy of game theory in contemporary theories of collective rationality and justice.

Finally, on 14 November 2025, he will speak at the Cournot seminar on the theme of ‘Social Choice and Games’.
