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...

Given a capacity function, an increase in demand will lead to a higher equilibrium price. Some economists take the capacity equilibrium for congestion. This paper corrects such an understanding and shows that congestion should only mean excess demand. The correct understanding should lead to...

Walters applied a demand and supply model to collect toll for easing congestion. This paper proves that his model is a lame duck, one without a supply function. It then works out a wholesome traffic and congestion model, to offer some alternative methods to solve congestion. This paper also...

We study whether subways alleviate road congestion by examining 45 subway line launches in China and using detailed data on road speed. Our difference-in-differences estimation finds that in the first year after a subway line is launched, rush-hour speed on nearby roads increases by about 4%....

This paper investigates regulation by auctions of private supply of congestible infrastructures in two networks settings: 1) two serial facilities, where the consumer has to use both in order to consume; and 2) two parallel facilities that are imperfect substitutes. There are four market...

The Bureau of Infrastructure, Transport and Regional Economics estimates of the costs of road congestion in Australian capital cities ($9.4 billion in 2005 and projected to more than double by 2020) are widely cited. But these projections appear to overstate the problem and provide little, if...

A.A. Walters derived a traffic flow function, and advocated toll to cure congestion. He wanted to save lives and monies, time is money, in congestion. NYC and Hong Kong have been practicing his policy for years, but surviving drivers are still tortured by congestion. Walters’ intention is...
