Sciences Po develops an interdisciplinary research program for the evaluation of public policies (in French: Laboratoire interdisciplinaire d'évaluation des politiques publiques, LIEPP), based on four founding units: Department of Economics, Centre de Sociologie des Organisations, Centre d'Etudes Européennes and Observatoire Sociologique du Changement. Its aim is to be (1) independent and non-partisan to ensure its credibility, (2) international to learn from experiences in other countries, and finally (3) multidisciplinary in order to achieve thorough and comprehensive knowledge of our environment and its institutional, social, political, legal and economic mechanisms. The project is financed as a through the Excellency Initiative of the French Government (Investissements d'Avenir: LABEX) with a budget of 10 million euros between 2011 to 2020.
