We develop a positive theory of pricing car access (by parking fees or cordon tolls) to downtown commercial districts. The model accounts for the special interests of downtown retailers and competing superstores at the edge of the city, and studies how lobbying by both groups shapes the...

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...

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 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,...

Political acceptability is the primary obstacle to implementation of road pricing in many cities. This paper studies the political economy of urban road pricing in its most common incarnation: cordon tolling. We relate voters' preferences for the road toll to its impact on the city's land...
