This paper estimates the marginal accident externality of driving in Central London by exploiting variation in traffic flow induced by the London Congestion Charge Zone using an instrumental variable approach. The charge attributed to a 9.4% reduction in traffic flow, which resulted in a less...

We demonstrate that women with children are much more likely to leave their job when they have a long commute, which is not true for men. Interpreting these results through the lens of a dynamic search model, we demonstrate that the marginal costs of commuting increase substantially for women...

Highway construction occurs nowadays mainly through widening of ex- isting roads rather than building new roads. This paper documents that highway widenings considerably reduce congestion in the short run, defined here as 6 years. Using longitudinal microdata from highway detector loops in the...

This paper considers European airline markets to establish a causal effect of competition on pricing dynamics. It shows that intertemporal price dispersion is strongly reduced by competition because flights booked close to departure time are on average priced substantially lower when competition...

One of the main unanswered questions in the field of urban economics is to which extent subsidies to public transit are justified. We examine one of the main benefits of public transit, a reduction in car congestion externalities, the so-called congestion relief benefit, using quasi-natural...

This paper investigates second-best congestion pricing in a monocentric city characterized by distortionary, rigid regulatory mechanisms in the housing market (building height restrictions, zoning and property taxation). The Pigouvian toll is shown to retain its optimality under any setting with...
