In this paper we examine the stochastic properties that long term aggregate traffic demand exhibits. Based on the results of the time series analysis, we examine how fractionally integrated processes affect real option valuation in road projects. We conclude that the long memory property we find...

This paper investigates the relationship between infrastructure investments and economic activity in Sweden for the period 1800-2000. In order to overcome the problem of endogeneity, independent time scales are used to analyze the relationship. The paper also examines the dynamics between the...

The parameters for travel time and travel cost are central in travel demand forecasting models. Since valuation of infrastructure investments requires prediction of travel demand for future evaluation years, inter-temporal variation of the travel time and travel cost parameters is a key issue in...

Shifting transportation to electrified modes, e.g., rail, is a politically attractive way of reducing greenhouse gas (GHG) emissions from the transportation sector. There is a vivid debate about the effects such a shift has on GHG emission and how these should be assessed and appraised. We argue...

According to the standard textbook analysis, drivers as a group will be worse off with congestion charging if not compensated by revenues. This result is confirmed by an analysis of the Stockholm congestion charging scheme using a static model with homogeneous users. However, both this static...

This study addresses a discrete common value environment with independent (one-dimensional) private signals, where the seller offers two identical units and the buyers have (flat) demand for both. Each session is conducted with 2, 3 or 4 buyers. Three auction formats are used: the...

This paper proposes a novel method for estimating the traffic demand risk associated with transportation. Using mathematical properties of wavelets, we develop a statistical measure of traffic demand sensitivity with respect to GDP. This measure can be adapted in a flexible way to capture risk...

Potentialen i Sverige för produktion av avfallsbaserad rötgas som kan uppgraderas för fordonsbruk överstiger långsiktigt inte 3 TWh (ca fyra gånger mer än idag). Vi finner att klimateffekten blir störst och kostnaden lägst om gasen används i fordon och fartyg som tankar från större...

This is a draft text for a chapter in Handbook on Research Methods in Transport Economics and Policy to be published by Edward Elgar Publishing. It provides an overview of issues related to scarcity in scheduled transport modes with emphasis on railways. The paper separates the scarcity or...

During the last decade six central European countries (Germany, Austria, Czech Republic, Slovakia, Poland and Switzerland) have introduced distance-based network tolls for heavy trucks. In Sweden, Denmark and the Benelux states the time-based Eurovignette is applied since the 1990-ies. All...
