  • Benefit measures for noise abatement : calculations for road and rail traffic noise
  • 2013
  • Ingår i: European Transport Research Review. - : Springer Science and Business Media LLC. - 1867-0717 .- 1866-8887. ; 5:3, s. 135-148

    • PurposeThe aim of this study is to estimate monetary abatement values for road and rail traffic noise that can be used for policy purposes. However, a main objective is to critically discuss the assumptions necessary to convert the monetary values elicited in willingness to pay (WTP) studies to values than can be use for policy purposes.MethodsWe employ the hedonic regression technique on Swedish data to elicit individuals' preferences for noise abatement. Our elicited values are then converted to policy values and critically examined based on findings from a literature review.ResultsWe show that WTP for road and rail not only differs in levels but also that the relationship between the noise level and the marginal value differs between the two sources. We also show that a health cost component added to the WTP estimate, based on the assumption of uninformed property buyers, will be small but not negligible and that also modest differences in the assumption of the discount rates will have a significant effect on the estimated values.ConclusionsThe main implications from this study are: (i) WTP for road and railway noise abatement differs not only on absolute but also marginal levels, (ii) Even small differences in the chosen discount rate, which is necessary to convert WTP values from a hedonic price study to policy values, have large effects on the policy values, and (iii) We show how to add a health cost component to the WTP estimates in order for the monetary estimates to reflect the total social cost. However, we argue that the motivation for doing so is weak and that more research is needed on this issue.

  • Bulleravgift för järnvägsoperatörer : prissättning enligt marginalkostnadsprinciper
  • 2006
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • The Swedish Parliament has decided that, in order to mitigate externalities in railway infrastructure, operators in the Swedish railway infrastructure shall pay charges based on short-run marginal social costs. Internalization of the social cost from noise is of particular interest, since it is the only environmental problem which people perceive as more troublesome today than they did in the early 1990s. Inclusion of a noise component in rail infrastructure charges raises two problems: (i) the monetary evaluation of noise abatement, since noise is a non-marketed good, and (ii) the estimation of the effect on the noise level that one extra train will create. We are interested in the marginal noise, since infrastructure charges based on the short-run marginal cost principle should be based on the effect from the marginal train, not the noise level itself. We show in this study that, based on already obtained knowledge, it is possible to implement a noise component in the rail infrastructure charges. Those values that already today are used to estimate the social cost from noise exposure (which in Sweden are based on noise from road-traffic) in cost benefit analysis can also be used to calculate the marginal cost. We recommend, however, that further research is carried out in order to get more robust estimates and to get estimates based on railway traffic. We also show that the existing noise estimation models can easily be modified to estimate the marginal noise. Noise infrastructure charges give the operators incentives to reduce their noise emissions. We believe that this kind of charges can be used to reduce overall emission levels to an optimal social level, but that it is important that these charges are based on monetary estimates for rail-traffic and not road-traffic.

  • Bullervärden för samhällsekonomisk analys : beräkningar för väg- och järnvägsbuller
  • 2009
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • Noise is a significant social problem. For example, more than 20 per cent of the European Union's population is exposed to higher noise than what is considered acceptable. The transport sector is a major contributor to society's increasing noise problem, due to increased traffic volumes and urbanization exposing more people to noise. Road traffic is admittedly the largest individual noise source in the transport sector, but other transport modes such as aircraft and railways are also responsible for considerable noise emissions. Noise entails costs for the society. This fact, and that society has different needs, means that policies and projects to reduce noise levels need to be evaluated to secure an efficient resource allocation. Benefit cost analysis is a powerful tool to evaluate noise abatement, but it requires both benefits and costs to be measured in a common metric, i.e. in monetary values. Today's official monetary values for all modes are based on the impact of road-traffic noise on property prices. It is a well established fact that the disturbance which individuals experience differs between modes, and therefore there is a need to estimate monetary values based on the respective modes. This report focuses on road and rail noise, two noise sources with different characteristics. This study describes the need to revise the current official Swedish policy values for noise abatement. Current values for road-traffic noise show a progressive relationship between the social cost and the noise level that is too strong, and values for railway noise has been missing and instead based on results for road noise. Valuation of health effects should also be based on EKM since it is sanctioned within the EU, instead of the approach now proposed by ASEK based on estimated total social costs from noise exposure in relation to estimates from willingness to pay studies.

  • Charging the polluters : a pricing model for road and railway noise
  • 2011
  • Rapport (övrigt vetenskapligt/konstnärligt)abstract
    • This study outlines a method to estimate the short run marginal cost (SRMC) for road and railway noise. It is based on standardized calculation methods for total noise levels and monetary cost estimates from well established evaluation methods. Here official calculation methods and monetary values are used for Sweden, but the estimation method for the SRMC outlined can be directly applied using other standardized noise calculation methods and monetary values. This implies that the current knowledge regarding the calculation of total noise levels and the evaluation of the social cost of noise can be extended to estimate the marginal effect as well. This is an important finding since it enables policy makers to price noise externalities in an appropriate way. Several sensitivity tests run for the SRMC show that: (i) increasing the total traffic on the infrastructure has only a minor influence, (ii) estimates are quite sensitive to the number of exposed individuals, and (iii) to the monetary values used. Hence, benefits transfer, i.e. using monetary values elicited based on road noise for railway noise, should be done with caution or not at all. Results also show that the use of quiet technology can have a significant effect on the SRMC. The fact that this model is able to differentiate not only modes of transport, but also vehicles and even technologies is an important finding. It is essential that the noise charges give the operators the right incentives to choose their optimal allocation.

  • Charging the Polluters A Pricing Model for Road and Railway Noise
  • 2013
  • Ingår i: Journal of Transport Economics and Policy. - 0022-5258 .- 1754-5951. ; 47, s. 313-333
  • Tidskriftsartikel (refereegranskat)abstract
    • By combining standardised calculation methods for total noise levels and monetary estimates from well-established evaluation methods, this study outlines a model to estimate the short-run marginal cost (SRMC) for road and railway noise that is able to differentiate not only modes of transport, but also vehicles and technologies. Several sensitivity tests run for the SRMC show that estimates are insensitive to traffic volume, sensitive to the number of exposed individuals, and sensitive to the monetary values used. Results also show that the use of quiet technology can have a significant effect on the SRMC.

  • Cognitive ability and scale bias in the contingent valuation method
  • 2007
  • Rapport (populärvet., debatt m.m.)abstract
    • This study investigates whether or not the scale bias found in contingent valuation (CVM) studies on mortality risk reductions is a result of cognitive constraints among respondents. Scale bias refers to insensitivity and non near-proportionality of the respondents' willingness to pay (WTP) to the size of the risk reduction. Two hundred Swedish students participated in an experiment where their cognitive ability was tested before they took part in a CVM-study where they were asked about their WTP to reduce bus-mortality risk. The results imply that WTP answers from respondents with a higher cognitive ability are less flawed by scale bias.
