This paper discusses and analyses whether congestion charges can be considered to be “fair” in different senses to the word. Two different perspectives are distinguished: the consumer perspective and the citizen perspective. The consumer perspective is the traditional one in equity analyses,...

The paper draws from already published material. In fact, a reader already familiar with the congestion charging literature will find few completely new findings or insights. The contribution of the paper is rather the selection of the most relevant, interesting, important and sometimes...

This paper addresses the problem of measuring the welfare benefits of a transport improvement. We formulate and analyze a rich spatial model that allows for spillovers, matching and income tax, in a setting with multiple work and residential locations and very general worker heterogeneity. The...

This paper explores the accuracy of cost estimates at different planning stages for Swedish transport infrastructure projects 2004-2022. Changes in project costs are tracked between the national investment plans established in 2010, 2014, 2018 and 2022. Cost estimates tend to increase...

This paper analyzes the accuracy of cost estimates for Swedish transport infrastructure projects 2004-2022, discusses causes of cost overruns, and suggests remedies. Cost estimates for all projects in the national investment plans 2010-2022 are tracked from early planning to completion. Final...

When benefits of proposed infrastructure investments are forecasted, residential location is usually treated as fixed, since very few operational transport models are able to forecast residential relocation. It has been argued that this may constitute a source of serious error or bias when...

A number of highly cited papers by Flyvbjerg and associates have shown that ex ante infrastructure appraisals tend to be overly optimistic. Ex post evaluations indicate a bias where investment costs are higher and benefits lower on average than predicted ex ante. These authors argue that the...
