Facts and Furphies in Benefit-Cost Analysis: Transport
Research Report 100
Benefit-cost analysis (BCA) is a valuable and widely used tool. To reduce the odds of misuse, this report probes some important methodological issues, especially as they relate to transport projects. The discussion is relatively non-technical and draws on case studies. The issues examined include claims that transport projects fail to measure certain benefits: employment creation, regional development, logistic adaptations and ‘positive externalities’. Also examined are the choice of discount rate, the treatment of taxes, the valuation of travel time, multi-criteria analysis as an alternative to BCA, and the role of national economic models.
