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...

It is sometimes argued that standard state-of-practice logit based models cannot forecast the demand for substantially reduced travel times, for instance due to High Speed Rail (HSR). The present paper investigates this issue by reviewing travel time elasticities for long-distance rail travel in...

The paper analyzes the political acceptability of policies targeted at relieving urban congestion. The paper combines a stylized model of an urban transport network with a somewhat more detailed model of the political process that incorporates interactions between voters, special interest groups...

This paper considers the choice between different approaches to contract for the construction and maintenance of infrastructure projects. The need to control for user and third party costs over the life cycle of an asset is demonstrated to be a core aspect of welfare maximising contract design....

It is still an open question whether the dynamic or the static format should be used in multi-unit settings, in a uniform price auction. The present study conducts an economic experiment in a common value environment, where it is found that it is more a question of whether the auctioneer wants...

Cost-benefit analysis (CBA) is often used when many transport investments need to be ranked against each other, for example in national investment planning. However, results are often questioned on claims that the ranking depends crucially on uncertain assumptions about the future, and on...

In this paper, renewal costs for railway tracks are investigated using survival analysis. The purpose is to derive the effect from increased traffic volumes on rail renewal cycle lengths and to calculate associated marginal costs. A flow sample of censored data containing almost 1 300...
