Stated preference (SP) surveys attempt to obtain monetary values for non-market goods that reflect individuals' “true”' preferences. Numerous empirical studies suggest that monetary values from SP studies are sensitive to survey design and so may not reflect respondents' true preferences....

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...

Individuals' perception of their own road-traffic and overall mortality risks are examined in this paper. Perceived risk is compared with the objective risk of the respondents' peers, i.e. their own gender and age group, and the results suggest that individuals' risk perception of their own risk...

This paper analyses the economic lifetime of roads in Sweden using a data over kilometres of new roads together with road network data and a centrality index constructed from population statistics. The relation between economic lifetime and centrality is performed by poisson regression. It is...

This study is the first to analyze hypothetical bias in a willingness to pay for time context as well as the first to test certainty calibration of the value of time. Hypothetical and real actions are compared in an experimental setting where the subjects are given an offer to leave the...

Using observational data covering the whole Swedish national road network for the period 1998-2002, this paper estimates a set of maintenance and operation cost functions. It is found that costs for all operation and maintenance measures increase with traffic intensity, with two exceptions;...

This paper takes its departure in two observations from the EU’s climate policy. First, the EU has adopted a dual approach with a trading scheme covering CO2 emissions from the energy intensive industry, while the remaining emitters are subject to emission taxes. Second, the targets are...

This paper examines the value to Swedish citizens of reducing the risk for salmonella bacteria in chicken filet. The contingent valuation (CV) study is based on the results of a postal questionnaire that was distributed to 2 000 randomly selected Swedish citizens aged 18-74. The valuation format...

This study examines the effect of road and railway noise on property prices. It uses the hedonic regression technique on a Swedish data set that contains information about both road and railway noise for each property, and finds that road noise has a larger negative impact on the property prices...

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...
