paper documents that highway widenings considerably reduce congestion in the short run, defined here as 6 years. Using … costs. Our paper contributes to an explanation why countries invest in roadworks even when the fundamental law of congestion …

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 … hypercongested for more than one hour per day. Hypercongestion accounts for about 40 percent of congestion-related welfare losses …

The purpose of the presentation is to analyze the labor market effects of a congestion charge when commuters have … continuously distributed value of time. Since a congestion charge raises the cost of commuting to work, it can decrease employment … loss from the decreased employment can even exceed the Pigouvian welfare gain from internalizing the congestion externality …

In studying congestion tolling, it is important to account for heterogeneity in preferences of drivers, as ignoring it … can bias the welfare gains. We analyse the effects of tolling, in the bottleneck model, with continuous heterogeneity in …

The traditional bottleneck model for road congestion promotes the implementation of a triangular, fully time varying …, charge as the optimal solution for the road congestion externality. However, cognitive and technological barriers put a … traditional bottleneck model to analyse how the coarse charge can be differentiated over two groups of travellers assuming …
