Optimal taxation of intermediate goods in the presence of externalities : A survey towards the transport sector
- 2006
-
Reports (pop. science, debate, etc.)abstract
- The paper surveys the literature on optimal taxation with emphasis on intermediate goods, or, more specific, freight (road) transport. There are two models frequently used, first, the one emanated from Diamond & Mirrlees' (1971) paper, where the production efficiency lemma made it clear that intermediate goods was not to be taxed. And, second, the Ramsey-Boiteux model where a cost-of-service regulation imposes a budget constraint for the regulated firm. In the latter model, in contrast to the first, freight transports (intermediate goods) are to be taxed in the Ramsey tradition, and thus trades the production efficiency lemma against a budget restriction. The paper also discusses welfare effects due to environmental tax reforms, with emphasis to what has become to known as the double dividend hypothesis. Finally, administrative costs in the context of optimal taxation is touched upon, a subject that is to a large degree repressed in optimal tax theory.

Revenues in discrete multi-unit, common value auctions : a study of three sealed-bid mechanisms
- 2009
-
In: Portuguese economic journal. - Lissabon : Springer. - 1617-9838. ; 8:1, s. 3-14
-
Journal article (peer-reviewed)abstract
- We propose in this paper a discrete bidding model, both on quantities and in pricing. It has a two-unit demand environment where subjects bid for contracts with an unknown redemption value, common to all bidders. Prior to bidding, the bidders receive private signals of information on the (common) value. Both the value and the signals are drawn from a known discrete affiliated joint distribution. The relevant task for the paper is to compare equilibrium strategies and the seller's revenue between the three auction formats. We find that, among the three auction formats below with two players, the Vickrey auction always gives the most revenue to the seller, where the discriminatory auction becomes second and the uniform auction last. We also find that, in equilibrium, bidders bid the same amount on both items in the discriminatory auction; a phenomenon we do not notice in either of the other two auction formats. There, different amount of demand reduction is encountered.

Considerations when calculating percent road centre from eye movement data in driver distraction monitoring
- 2009
-
In: Proceedings of the Fifth International Driving Symposium on Human Factors in Driver Assessment, Training and Vehicle Design. ; , s. 132-139
-
Conference paper (peer-reviewed)abstract
- Percent road center (PRC) is a performance indicator which is sensitive to driver distraction. The original definition of PRC is based on fixation data extracted from eye movement recordings, but it has also been suggested that PRC can be determined directly from the gaze data without segmenting it into saccades and fixations. The primary aim of this paper is to investigate if this is the case.Naturalistic driving data from a small scale field operational test comprising seven vehicles was used in the evaluation. It was found that PRC time traces based on gaze data and fixation data, respectively, were highly similar (correlation coefficient=0.95, average wavelet semblance=0.84) except for an absolute amplitude difference of about 8%. This indicates that the two approaches can be used interchangeably and that the processing step of segmenting gaze data into saccades and fixations can be left out.In addition to this finding, design issues related to the calculation of PRC are investigated. Especially, the impact of gaze cases pointing towards the intersection of the road centre area and the centre rear mirror were investigated. Results lead to conclude that gazes and fixations on the centre rear mirror should be removed from the PRC calculations, as they may negatively influence the correctness of the performance indicator.

Antisladdsystem : förarens kunskap om antisladdsystem och hur de påverkas av systemet
- 2008
-
Reports (pop. science, debate, etc.)abstract
- Syftet med rapporten är att ta reda på hur förares körsätt påverkas av att köra en bil med antisladdsystem och vilken kunskap de har om säkerhetssystemet. Denna rapport behandlar förarna till de bilar, typ Volvo S40, som har antisladdsystem. En enkät med 17 frågor har skickats ut till ett slumpat urval på 320 personer, 160 som har systemet och 160 som inte har det.

Initial plan of dissemination and use of results
- 2009
-
Reports (other academic/artistic)abstract
- This document contains the initial plan for using and disseminating knowledge and foreground developed within the ITERATE Project.The Deliverable contains five main Chapters and an Appendix.The first Chapter describes the purpose of the document, its structure, and introduces the other sections. Chapter 2 and 3 define the dissemination strategy of the ITERATE project and provide a classification of dissemination activities. For each type of dissemination action, the corresponding implementation approach is proposed. Then, for each type of dissemination activity, the actions already performed and those planned are described in some details. The dissemination materials already produced by the project and their usage are briefly described. Materials and products already completed, as well as planned, are described, even though a dedicated Deliverable is foreseen in the future that will contain copies of the actual products provided for dissemination purposes. The Exploitation plan is discussed in the last Chapter of the Deliverable. The two different natures and typology of partners , i.e., academic and industrial/consultancy, are considered. In particular, for each partner, a market and competition analysis is performed and the objectives and guidelines for subsequent exploitation of the results is preliminarily discussed. Finally, the appendix contains, for completeness, the Dissemination and Exploitation Questionnaire utilised to collect information among partners.

Tillsatsmedel i asfalt : påverkan på arbetsmiljö och omgivning (2006-02-06). Slutrapport
- 2006
-
Reports (other academic/artistic)abstract
- Vissa tillsatsmedel upplevs idag som besvärliga för arbetsmiljön vid tillverkning och utläggning av asfaltmassa. Vidstående projekt som finansierats av SBUF och Peab Asfalt AB syftar till att ta fram relevanta fakta om tillsatsmedel och dess hälso- och miljöproblem. Projektet har dels inriktats som en förstudie av vad som hitintills har gjorts inom asfaltmiljöområdet både i Sverige och i utlandet, dels kompletterande fältmätningar vid asfaltläggning av polymermodifierad asfalt. Studien har utförts i samarbete mellan Peab Asfalt AB, VTI och Previa/ARA-miljö.

Analys av polisens alkoholutandningsprov i fem län åren 2001-2003
- 2007
-
Reports (other academic/artistic)abstract
- The extent and results of the police breathalyser tests in Stockholm, Västerbotten, Östergötland, Skåne and Västra Götaland Counties over the period 2001-2003 have been analysed. The primary aim is to uncover and describe shortcomings in existing data, not to estimate the extent of drink driving. The analysis has been made with reference to the codes applied by the police to describe the type of control at which the test was made. These codes are - 0) Police initiated driver control - 1) "Random" control (not random in the strict statistical sense) - 2) Control because of a road traffic accident - 3) Targeted control (e.g. at strategically selected points such as shops selling alcoholic drinks) - 4) Other codes - It is mainly the breathalyser tests coded by the police as 0, 1 and 3 that are examined in the analysis. The other codes appear very rarely in the controls made.
