La Région Île-de-France soutient le projet de recherche de Marion Leroutier, Assistant Professor en économie au CREST, qui vise à promouvoir les mobilités actives et réduire les nuisances liées aux déplacements en voiture en milieu urbain.
Marion Leroutier, Assistant Professor en économie
Marion Leroutier est actuellement Assistant Professor en économie à l’ENSAE Paris et chercheuse au CREST. Spécialisée dans l’économie de l’environnement, elle explore l’impact des politiques climatiques, et les freins et leviers pour accélérer la transition écologique. Son parcours académique et professionnel se distingue par des travaux sur des thèmes contemporains comme le coût économique et sanitaire de la pollution atmosphérique et la mobilité durable.
L’appel à projet Chaires SHS de la région Île-de-France
Pour accompagner les projets de recherche en sciences humaines et sociales, la Région Île-de-France a mis en place les Chaires SHS. Cet appel à projets vise des initiatives qui renforcent les liens avec le territoire francilien en répondant aux enjeux régionaux, notamment dans les domaines de la mobilité, de la durabilité, et de l’inclusion sociale. Les projets financés sont sélectionnés pour leur potentiel à éclairer les politiques publiques et à favoriser le bien-être de ses habitants.
Le projet “Cyclomob” : une approche multidimensionnelle pour la mobilité durable
Le projet de Marion Leroutier, intitulé “Cyclomob : vers une mobilité urbaine durable ? Encouragement de la transition vers les mobilités actives par les politiques publiques”, se concentre sur la promotion des mobilités actives comme le vélo dans des zones urbaines denses, où la voiture reste un moyen de transport prépondérant mais source de pollution et de sédentarité. Le projet vise à étudier l’efficacité de différents leviers pour encourager les résidents à adopter le vélo, et leurs impacts sur la mobilité et les émissions polluantes.
Deux axes de recherche principaux structurent le projet :
- L’impact des infrastructures cyclables
Dans un premier temps, Marion Leroutier et ses co-auteurs analyseront l’effet causal des nouvelles infrastructures cyclables mises en place en Île-de-France. Cette phase du projet mesurera comment ces infrastructures influencent non seulement le trafic et la qualité de l’air, mais également les préférences et habitudes des résidents en matière de transport. Les données recueillies permettront d’évaluer le rôle de ces aménagements dans la transition vers des mobilités actives et moins polluantes, contribuant ainsi à un urbanisme plus durable. - Une campagne d’information axée sur les bénéfices sanitaires du vélo
La deuxième partie du projet consiste en une intervention randomisée contrôlée, visant à évaluer l’efficacité d’une campagne de sensibilisation centrée sur les bénéfices pour la santé de l’utilisation du vélo. Cette campagne ciblera les usagers potentiels en leur fournissant des informations détaillées sur les bénéfices sanitaires de la pratique régulière du vélo. Ce volet de l’étude examinera dans quelle mesure des arguments sanitaires peuvent influencer le choix de modes de transport plus actifs.
Perspectives et impacts attendus
Le projet “Cyclomob” devrait apporter des éclairages précieux pour les décideurs publics, en démontrant comment les infrastructures et les campagnes de sensibilisation peuvent être des leviers pour encourager des mobilités durables. Il permettra de mesurer les effets concrets sur la qualité de l’air et la santé des habitants, tout en contribuant à l’évolution des politiques de transport urbain vers des pratiques plus écologiques. En ce sens, “Cyclomob” s’inscrit pleinement dans les objectifs de la Région Île-de-France de faire de la mobilité durable un pilier de la qualité de vie et de la résilience urbaine dans la région.
Ce financement de la Région Île-de-France permet à Marion Leroutier d’approfondir et de poursuivre ses recherches déjà entamées sur cette thématique. En effet, elle a récemment documenté les inégalités de contribution aux émissions polluantes en Île-de-France, liées aux déplacements quotidiens des habitants (lien vers l’article co-écrit avec Philippe Quirion), et exploré les options de réduction de ces émissions, notamment par le biais d’un report modal vers les transports en commun et le vélo (lien vers l’article co-écrit avec Philippe Quirion et lien vers l’article de vulgarisation). Ce soutien régional lui offre ainsi l’opportunité d’amplifier l’impact de ses recherches en faveur d’une mobilité durable en Île-de-France.

Olivier Gossner Named Fellow of the Econometric Society
Olivier Gossner: A Leading Specialist in Game Theory
Olivier Gossner is a prominent scholar at the intersection of economics and mathematics, renowned for his expertise in game theory. His research focuses on repeated games, the strategic use of information, and bounded rationality, exploring how individuals and institutions make decisions under uncertainty.
In his recent work, Gossner has introduced innovative models of strategic reasoning and proposed a significant reform to the Solvency II regulation, advocating for a reallocation of insurance capital towards the productive economy. His contributions aim to reshape how financial systems can better support economic growth.
Gossner holds multiple prestigious titles, including Fellow of the Game Theory Society, where he also serves as the Vice President for Communications, and now, Fellow of the Econometric Society. In recognition of his groundbreaking research, he was awarded an ERC advanced grant from the European Commission for his SInfoNiA project, which further advanced strategic information theory in economics.
Overview of The Econometric Society
Founded in 1930, the Econometric Society is one of the most prestigious academic societies in the world, bringing together leading economists and statisticians. Its mission is to advance economic theory in its relation to statistics and mathematics. The Society is known for its rigorous standards, and membership includes many of the most influential thinkers in economics over the past century.
The Econometric Society organizes major conferences around the world and publishes three of the field’s top journals: Econometrica, Quantitative Economics, and Theoretical Economics. Its influence extends across academic circles and into the policy-making world, where insights from its members shape major economic decisions globally.
What It Means to Be a Fellow of the Econometric Society
Becoming a Fellow of the Econometric Society is one of the highest honors in the field of economics. Each year, the Society recognizes a select group of economists whose research has made a profound impact on the field. The nomination process is highly competitive, and Fellows are selected based on their body of work, their contributions to advancing economic knowledge, and their influence on the academic community.
For Olivier Gossner, this fellowship represents a crowning achievement in a career already full of significant milestones. It places him in a distinguished group of scholars who have shaped modern economic theory and practice, and it recognizes his contributions to game theory and decision-making processes.

Welcome Day at CREST – A Great Start to the New Academic Year
On October 10, 2024, CREST held its annual Welcome Day, an event dedicated to welcoming new members (research assistants, PhD students, postdoctoral fellows, and faculty members), offering them an introduction to the laboratory through presentations from the management team and thematic leaders.
This year, all CREST sites (CREST-ENSAE Paris, CREST-ENSAI, and CREST-Télécom Paris) gathered at the ENSAE Paris campus.
The presentations provided the new members with a comprehensive understanding of CREST’s institutional environment, particularly its affiliations with the Institut Polytechnique de Paris and the University of Rennes. Each newcomer also had the opportunity to introduce themselves and their research project, fostering exchanges with both new and existing members of CREST.
The thematic leaders highlighted well-being initiatives at CREST, as well as the structure of the doctoral program at IP Paris. The event also allowed the administrative team to outline their roles and share useful recommendations.
Our scientific data engineers demonstrated Onyxia, a solution recently deployed in collaboration with GENES.
Finally, CREST PhD students shared information about various reading groups, other lab initiatives, and teaching opportunities available during the doctoral program.
This event also marked the unveiling of CREST’s new institutional brochure for the academic year, which provides an overview of the lab’s research and teaching activities, as well as its prestigious achievements.
