Congestion Pricing At The Wrong Price

"When working out how much a certain number of people would be willing to pay for a privilege, economists construct something called a "demand curve." When they did it for this exercise, they estimated that a reduction in traffic of 15 percent would require that £5 fee. Unfortunately, they got their sums wrong. The reduction in traffic has been far greater than anticipated. This has several consequences. First, it has meant a shortfall in Capita's revenues. Livingstone has been forced to address this problem by granting them £32 million of London taxpayers' money to allow them to make their required profit... As a result, he has been forced to postpone a planned extension to the Docklands Light Railway." [Thanks to Joan Friedman for an updated and corrected link.]
