Abstract
The use of cost benefit techniques in analysing the relationship between infrastructure and economic growth is discussed. Particular problems regarding infrastructure investments and social efficiency in Norway caused by the topography and parallel transport systems are outlined. Three case studies are then described which were planned to bring substantial industrial benefit. These include a tunnel route from Oslo to Bergen, the high speed rail link between Oslo and Gothenburg, and the short take-off and landing system (STOL). It is suggested that such projects are very sensitive to the level of `inconvenience cost' or `willingness to pay'. A micro-economic transport model is presented which incorporates inconvenience costs.
