The Institut des politiques publiques (IPP) has been established as part of a research partnership between the Paris School of Economics (PSE) and the ENSAE-ENSAI Group. The IPP does not have its own legal personality, but is hosted by the PSE-École d’Économie de Paris Foundation for Scientific Cooperation.

Scientific and collegial governance

The Institut des politiques publiques is overseen by a Steering Committee co-chaired by the Director of the Paris School of Economics and the Director of the ENSAE-ENSAI Group. The IPP’s Steering Committee meets once a year to set the Institute’s strategy.
