Laboratory for Interdisciplinary Evaluation of Public Policies (LIEPP)

The Laboratory for Interdisciplinary Evaluation of Public Policy (LIEPP) is a Sciences Po research platform funded under the "Investments for the Future" program of the National Research Agency (ANR). Created in 2011, this laboratory is redeployed from 2020 in partnership with Université de Paris. Its aim is to develop the evaluation of public policies through an interdisciplinary scientific approach.

The research carried out at LIEPP analyses the functioning and effects of many public policies such as education policies, environmental policies, migration policies, health policies, social and socio-fiscal policies. They address, in a transversal approach, the dimensions of public policies of major societal issues, such as environmental risks, inequalities, discrimination, the crisis of expertise and democracy.

LIEPP is based on an innovative evaluative research approach, combining quantitative, qualitative and comparative methods, and combining a high level of scientific requirements with the concern for the dissemination and translation of research results among public actors. 

Through its activities, LIEPP works to better anchor the approach of evaluation in academic research in the social sciences. But it also works in connection with experimental sciences, particularly in the context of collaborations between University of Paris and Sciences Po, to better connect this knowledge to their consequences for public action. Finally, in the sphere of public policy, it contributes to the public debate and reflections on evaluation involving other actors (administrative, parliamentary, associations, etc.), with a view to promoting the process of evaluation and improving its quality.

All the projects carried out at LIEPP benefit from the support provided by the ANR and the French government under the Investments for the Future program LABEX (ANR-11-LABX-0091, ANR-11-IDEX-0005-02) and the Idex University of Paris (ANR-18-IDEX-0001).

Research Groups

Discriminations and Category-Based Policies

To evaluate the extent and the growth of discrimination, and analyse the challenges it poses to policy action in the fight against social inequalities.

Environmental Policies 

To make sense of policies in the field of environmental protection in the broadest sens and to inform the choices of decision-makers ans stakeholders. 

Evaluation of Democracy

To provide an interdisciplinary, comparative and innovative assessment of the democratic process which leads to the implementation of public policies.

Educational Policies

To enrich the understanding  of key and current education policies and to inform policy actors about their choices.

Socio-fiscal Policies

To gather multiple points of view in order to provide a comprehensive evaluation of social and employment policies based on tax expenditures.

Another research group focuses on health policies is being created.
