This article compares data envelopment analysis and stochastic frontier analysis to assess efficiency and productivity growth of Norwegian grain producers. Previous studies have dealt with either one of them and less of both. For the assessment of productivity growth or regress, Malmquist...

Although governments often respond to the prevalent cost overruns of transportation projects by reforming the agencies charged with overseeing the construction of projects, the transportation research literature has not provided statistical evidence as to whether such reforms assist in reducing...

In this article we evaluate the technical efficiency of Norwegian container ports relative to a frontier composed of the best performing among themselves and other comparable Nordic and UK ports. The rationale is that a technical efficiency assessment of Norwegian container ports has not been...

<title>Abstract</title> What determines decision‐makers’ preferences for road projects has been a subject of debate in the transport economics literature for decades. Because economic assessments of road projects are conducted subject to demands by decision‐makers in almost all western European countries...

<title/> This paper analyzes efficiency in the Norwegian road sector by using two competing methods. The first is Data Envelopment Analysis (DEA), while the second is Deterministic Frontier Analysis (DFA) with a Cobb-Douglas kernel specification. Both approaches show similarities with respect to...

This paper evaluates the accuracy of the annual national road traffic growth-rate forecasts that are prepared by the Norwegian road authorities. The rationale for the study is the fact that national and regional traffic growth-rate forecasts are the basis for policy formation, and inaccurate...

All undertakings in the transport sector should be subject to some form of cost-benefit analysis (CBA) as part of an informed decision-making process. CBA is used in this paper to advise the Norwegian government on the impact of limiting the height of heavy vehicles to 4.0m, as suggested in...

This paper analyses the level of efficiency at which road toll companies are operated in Norway. Two alternative methods are applied for this purpose: data envelopment analysis (DEA) and stochastic frontier analysis (SFA). The data comprise a total of 20 toll companies that have been in...
