Mise en place d'une expérience avec le grand public: entre recherche, vulgarisation et pédagogie

We present the implementation of an economic experiment conducted simultaneously in 11 French cities, with over 2700 participants, during four uninterrupted hours, during a popular-science event held in September 2015. Our goal is both to provide a roadmap for a possible replication and to discuss how the discipline can invest in new fields (science popularization, popular education, public communication).
