Death of Roger Guesnerie, professor of economics at the School

It is with great sadness that we learned of the passing of Roger Guesnerie.

A former student of the École Polytechnique (X62), he graduated with a degree in civil engineering (corps des ponts et chaussées). After completing his training at the École Nationale des Ponts et Chaussées (1967) and the University of Toulouse, he chose a career in economic research.
At the beginning of the 80s, he set up the doctoral program in Analysis and Political Economy at EHESS, a program in which the School's researchers are still involved today, and oversaw the creation of CERAS, the School's economics laboratory, as its scientific director. In 1991, he took over as director of DELTA, the joint economics laboratory of the ENS and EHESS, and in 2000, he held the Chair of Economic Theory and Social Organization at the Collège de France.
He was very actively involved in the creation in 2005 of the UMR PjSE, bringing together DELTA and CERAS, and then in 2007 of the Paris School of Economics, a scientific cooperation foundation of which the École nationale des ponts et chaussées is a founding member. He chaired the foundation until 2015.

Beyond the high quality of his research, widely recognized in France and internationally, he contributed significantly to the School's economics teaching (course on Economic choices in projects), thereby helping to perpetuate the long tradition of economics at the École nationale des ponts et chaussées. He liked to see economics as “an activity well suited to the profile of civil engineers” because “the back-and-forth between concrete issues, particularly those relating to civil engineering, transportation, the environment, and industry, and the activity of modeling and international outreach” are "its defining characteristics " (Revue PCM, 1984).
