In 2011, OSE – Opening Economics, supported by PSE, was one of the hundred or so projects selected in the Labex section of the «Grand Emprunt» scheme.

The Labex OSE, co-ordinated by PSE, involves a number of partners: two laboratories (the Centre for Economics at the Sorbonne and Paris-Jourdan Economics); the economic demographics section of the INED; and three independent research centres: the CEPII, the CEPREMAP and J-PAL Europe.

This project began from the observation that the central paradigm of economics is based on the notion of the rational individual, which has remained remarkably powerful, but whose limits become more and more evident in an increasingly complex world. The project OSE – Opening Economics aims to address the challenges facing the central paradigm of economics, in the fields of expertise of the partners.
