Institutional History

The Origins of the Paris School of Economics

The creation of the Paris School of Economics is the final chapter of the long gradual process of bringing together and finally merging a number of different research units in Economics. This process started at the end of the 1980s.


Creation of CERAS, the Economics research centre of the ENPC.


Creation of DELTA, from the fusion of the Centre d’Économie Quantitative et Comparative of the EHESS and the Laboratoire d’Économie Politique of the ENS.
A number of different research centres joined DELTA at the Jourdan campus: the Laboratoire d’Économie Appliquée (LEA) of INRA (1998), the Laboratoire des Sciences Sociales of the ENS (1998), CEPREMAP (2001 - created in 1967) and finally CERAS (2002).


Four of the Economics research centres of the Jourdan campus (DELTA, CERAS, and the two separate halves of Cepremap) merge to produce one single research centre, Paris-Jourdan Sciences Economiques (PSE).
December 1st : Birth of the « Association de Préfiguration de l’Ecole d’Economie de Paris » (the Preliminary Assocation of the Paris School of Economics), which brings together all of the research centres present on the Jourdan campus as well as the future Centre d’Economie de la Sorbonne of the University of Paris 1. The director of this Association is Thomas Piketty.


The research centres of the University of Paris 1 merge into one sole research centre, the Centre d’économie de la Sorbonne (CES).
The Centre Maurice Halbwachs, which includes a number of different research centres in Sociology and Anthropology, moves onto the Jourdan campus.

April 18th : The loi de programme pour la recherche creates the concept of Fondations de Coopération Scientifiques (Scientific Research Foundations).

December 21st : A decree creates the Foundation of the Paris School of Economics.


After three years devoted to the creation of PSE, Thomas Piketty chooses to return to research and resigns as Director in April. The new Director is François Bourguignon, former Chief Economist at the World Bank.


The labex “OSE-Opening Economics” led by the Paris School of Economics with numerous scientific and institutionnal partners is selected within the Grand Emprunt.


February the 1st: Pierre-Yves Geoffard is the new PSE Director, right after François Bourguignon.PSE President is Roger Guesnerie.


September 3, Roger Guesnerie, professor at the Collège de France and president of PSE since its creation in December 2006, has left office. Jean-Pierre Danthine, former vice-president of the Swiss National Bank, replaces him at the head of the institution.

The General Commission for Investment presented the winners of the latest component of the Investment for the Future programme (known as PIA3), in the “University research schools” (EUR) category. The project “Paris Graduate School of Economics” proposed by PSE was one of those chosen projects, winning an allocation of 15.8 million euros over the next ten years. In addition to this, for 13 of the 29 winning projects, the government announced the extension of the grants awarded to their Laboratoires d’excellence (LABEX). The PSE is among those winners, too, for its LABEX “OSE – Open up Economics”, granted in March 2011.
