The value of a Quality-Adjusted Life-Year (QALY) and the Value of a Statistical Injury (VSI) are important measures within health economics and transport economics. Several studies have therefore estimated people's WTP for these estimates, but most results show problems with scale insensitivity....

To decide how much resources to spend on reducing mortality risk, governmental agencies in several countries turn to the value of a statistical life (VSL). VSL has been shown to vary depending on the size of the risk reduction, which indicates that WTP does not increase near-proportional in...

Gender differences in fish processors' willingness to pay for a group-owned fish solar tent dryer (FSTD) are being assessed by using the double hurdle model. Willingness to pay (WTP) responses from 382 randomly selected fish processors were elicited through a bidding game in a contingent...

Stated preference methods using surveys to elicit willingness to pay have been shown to suffer from hypothetical bias and scope/scale bias. Hypothetical bias usually means that willingness to pay is exaggerated in the hypothetical scenario and scope/scale bias means that there is an...

Abstract: Public investments are dynamic in nature, and decision making must account for the uncertainty, irreversibility and potential for future learning. In this paper we adapt the theory for investment under uncertainty for a public referendum setting and perform the first empirical test to...

Hypothetical bias is a serious problem of stated preference techniques. The certainty approach calibrates answers by assessing different weights to remedy respondents' valuation. However, very little research has been done to find a link between economic theory and empirical treatment of...

Validity in contingent valuation (CV) is often tested through the sensitivity of estimated willingness to pay (WTP) to the size or quality of a good or service ('more is better' and near proportionality). We investigate the performance of two communication aids (a flexible community analogy and...

This study examines the effect on respondents' willingness to pay to reduce mortality risk by the order of the question in a stated preference study. Using answers from an experiment conducted on a Swedish sample where respondents' cognitive ability was measured and where they participate in a...

Background: Economic evaluation of policies regarding out-of-hospital cardiac arrest (OHCA) is important and we estimate the value of a statistical life (VSL) for OHCA victims. Method: Responses to a national Swedish mail survey in 2007, based on the stated-preference technique (contingent...

Altruistic preferences of various forms may cause difficulties in welfare economics. In the valuation of public goods, such preferences are believed to help explain the substantial non-use values found in many stated preference (SP) valuation surveys. However, studies analysing the effect of...
