Realised with Jean-Pierre Ponssard, this “Cahier de l’ILB” is dedicated to sustainable mobility. It deals with various subjects : how driving restrictions affect urban pollution, carbon footprint of motor vehicles in the United States, hydrogen vehicles, the importance of strong regulation to reap the full benefits of innovation in mobility.

In the social norms literature concerned with the private provision of public goods there seems to be an implicit belief that it is best to have all agents adhere to the ‘good’ social norm. We challenge this view and study optimal government policy in a reference model (Rege, 2004) of public good provision and social approval in a dynamic setting.
