This paper investigates the welfare costs of urban traffic by considering its implications on good-level prices. Using price data for 40 products from 70 cities (covering 47 countries) for multiple years, the estimation results suggest that the elasticity of good-level prices with respect to 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,...

The geographical location of economic activity within the United States has important implications for carbon mitigation. If households clustered in California's cities rather than in more humid southern cities such as Memphis and Houston, then the average household carbon footprint would be...
