Jean-Jacques Laffont

Jean-Jacques Laffont lends his name to the main auditorium of the Toulouse School of Economics (TSE), a modern university building in the heart of Toulouse, on Rue du Doyen-Gabriel-Marty, close to Place Saint-Pierre. It is a spot where the history of modern economics meets striking contemporary architecture, offering visitors a different angle on the city beyond its more traditional monuments.

Who was Jean-Jacques Laffont?

Jean-Jacques Marcel Laffont (1947–2004) was a French economist who specialized in public economics and information economics. He studied at the University of Toulouse and at the École Nationale de la Statistique et de l'Administration Économique (ENSAE) in Paris, and earned his PhD in economics from Harvard University in 1975. Back in Toulouse, he founded the Institut d'Économie Industrielle (IDEI), a research institute that became the seed from which the Toulouse School of Economics grew into one of the most respected economics faculties in the world.

What can you see here?

The Jean-Jacques Laffont auditorium is the main hall of the TSE building, used for lectures, conferences and academic events. The building itself, which the school moved into in 2019, sits right in the center of Toulouse near the historic Place Saint-Pierre and stands out for its contemporary design — the project won the prestigious French architecture prize Équerre d'Argent in 2020. Besides the auditorium, the building also has a wing bearing Laffont's name, housing facilities for the school's doctoral program in economics.

Visitors exploring Toulouse should know this is not just any lecture hall — the university dedicated it specifically to honor its most internationally recognized economist. The building's open, city-facing design, blending academic function with public space, is a good example of how Toulouse invests in 21st-century academic architecture.

Why does this place matter?

The auditorium was formally inaugurated and dedicated to Jean-Jacques Laffont on 14 September 2022, in a ceremony attended by leadership of Université Toulouse Capitole, the directors of TSE, and members of the economist's family. The tribute recognized his central role in building what the university calls "the project of Toulouse economists" — the research community that turned the city into one of the world's leading centers for economic research, alongside places like Cambridge or Chicago.

How to get there?

The TSE building is centrally located in Toulouse, an easy walk from Place Saint-Pierre and the old town. It makes a natural stop for combining a stroll through Toulouse's historic center — with its pink-brick facades, churches and the banks of the Garonne — with a short look at this modern economics campus. Its downtown location means no special transport is needed; most central landmarks are within walking distance.

When to visit?

Since the auditorium is part of an active university, the building feels most alive during the academic year, when lectures and events fill the space. That said, the architecture and surroundings can be admired from the outside year-round, and a walk through this part of Toulouse pairs well with visits to the city's more classic historic sites nearby.
