The theory of road pricing developed for single links suggests time andlocation varying charges equal to the marginal congestion cost at the efficientlevel of traffic. The second-best network counterpart is derived, but would beinfeasible to implement. Cordon tolls are feasible, and their...

People who anticipate the introduction of a policy can adapt their behavior, perhaps in ways that make the policy ineffective and exacerbate the problem to be addressed. This paper develops a political economy model to study strategic behavior related to the introduction of congestion policies,...

In downtown areas, what proportion of curbside should be allocated to parking? In contrast to most previous work on the economics of parking, this paper focuses on optimal curbside parking capacity in both first-best (where pricing is efficient) and second-best (where pricing is inefficient)...

This paper studies the political economy of cordon tolls, the most common form of road pricing in cities. We consider a monocentric city inhabited by renters and resident-landowners. A cordon toll raises the rental price of land within the cordon, and it reduces rents outside this area. Hence,...

Ride-hailing applications create new challenges for governments providing transit services, but also create new opportunities to raise tax revenue. To shed light on the effect of taxing or subsidizing ride-hailing applications, we extend a pseudo-monocentric city model to include multiple...

This paper analyzes cordon tolling using a simple model where space is discrete rather than continuous, with commuting costs incurred only on two congested bridges. The first-best regime requires tolls on both bridges, whereas only the inner bridge is tolled under the cordon-toll regime. While...

We estimate the marginal external congestion cost of motor-vehicle travel for Rome, Italy, using a methodology that accounts for hypercongestion (a situation where congestion decreases a road's throughput). We show that the external cost - even when roads are not hypercongested - is substantial,...

This paper shows that the inefficiency of fiscal decentralization in the presence of spillovers, a main tenet of the decentralization literature, is overturned in a particular transportation context. In a monocentric city where road (bridge) capacity is financed by budget-balancing user fees,...

Transport has significant externalities including carbon emissions and air pollution. Public health research has identified additional social gains from active travel, due to health benefits of physical exercise. Per mile, these benefits greatly exceed the external costs from car use. We...

In 2022, Germany introduced a temporary 9-euro monthly ticket for unlimited local and regional public transport. We investigate its impact on mobility patterns, including increased public transport usage, reduced car traffic, and rail network congestion. Using difference-in-difference and...
