Paris-Jourdan Sciences Economics is a research center funded by Centre National de la Recherche Scientifique (CNRS), École des Hautes Etudes en Sciences Sociales (EHESS), the École des Ponts ParisTech and the École normale supérieure (ENS). PSE-Jourdan resulted from the merger in January 2005 of the four research groups which existed at that time on the Jourdan Campus:

DELTA (CNRS-EHESS-ENS)
CERAS (CNRS-ENPC)
and the two research groups of CEPREMAP.

PSE-Jourdan now also includes the Laboratoire d’Economie Appliquée (INRA). The researchers of PSE-Jourdan actively participate in the Analyse et Politique Economique Masters and Doctoral Programme. The research and teaching activities located on the Jourdan campus constitute the Jourdan component of the Paris School of Economics.
