The eects of road pricing on driver behavior and air pollution Matthew Gibsona,∗, Maria Carnovaleb aDepartment of Economics, Williams College, Schapiro Hall, 24 Hopkins Hall Dr., Williamstown MA 01267 bCERTeT, Università Bocconi and Duke University, Duke Box 90239, Durham, NC 27708 Abstract Exploiting the natural experiment created by an unanticipated court injunction, we evaluate driver responses to road pricing. We nd evidence of intertemporal substitution toward unpriced times and spatial substitution toward unpriced roads. The eect on trac volume varies with public transit availability. Net of these responses, Milan's pricing policy reduces air pollution substantially, generating large welfare gains. In addition, we use long-run policy changes to estimate price elasticities.
