One of the goals of transport policy in Sweden is to minimize the impact from transport on the environment. Using a database consisting of over 800 rail, road and maritime transport infrastructure projects, we estimate whether environmental factors, such as negative environmental effects arising...

We study the effect of uncertainty about the greenhouse gas emissions arising from the production of biofuels on trade policy, in the presence of lobby groups and two policy instruments, trade policy and biofuels mandates. We show that in the presence of biofuels mandates it would be optimal...

We study factors affecting the choice of projects to be included in the National Transport Infrastructure Plan for 2010-21 in Sweden, controlling for the CBA results. The centre-right government tended to favour counties that voted for it, and favour rail investments over road. We find no...

One way of mitigating the negative effects of noise from road traffic is to include the external cost of noise in a road charging system. This study shows how standardized calculation methods for road traffic noise can be used together with monetary estimates of the social cost of noise exposure...

This paper measures the external health cost due to emissions from different sources in the Stockholm area using the Impact pathway approach. The estimated health impact is the result of detailed dispersion modelling with high spatial resolution. We make separate calculations for the impact that...

Although the value of reducing mortality risks and that of reducing life year losses are closely related to each other, the valuation literature seems to treat them rather separately resulting in conflicting value estimates. While the former is more concerned with saved statistical lives from...

Emissions from traffic impose negative effects on human health, and recent evidence indicates that particulate matters (PM) are the detrimental air pollutant that causes most life years lost. To improve the efficiency of resource allocation, various mitigation measures have been proposed for...

Simulations of net cost contracts augmented with a subsidy per passenger for public transport bus operators in Sweden indicate that such contracts may shift the operators profit maximising price and frequency combination in a direction that yields an increased patronage. The calculations suggest...

The somewhat ad-hoc method of certainty calibration, based on self-stated preference certainty follow-up questions, has been found to be a successful method of eliminating or reducing hypothetical bias in stated preference studies. But is the preference certainty really context dependent, or do...

In this study, Swedish stated preference data is used to derive estimated values of commuting time (VOCT). Both spouses in two-earner households are individually making trade-offs between commuting time and wage; both with regard to their own commuting time and wage only, as well as when both...
