We compare different contingent valuation question formats with each other and with observed behaviour for a non-monetary estimation task, the expected number of kilometers travelled by automobile. Open-ended questions, open-ended follow-up questions, dichotomous choice (DC) questions, and...

The aim of this paper is to introduce and test a new approach for the measurement of the marginal rate of time preference for life-years gained based on contingent valuation techniques. A simple binary willingness to pay question is administered in a general public sample of two age groups (34-5...

In this study, one group of respondents is offered to purchase a safety device to be installed in their cars, while another group is offered a public safety program (improved road quality) which results in the same size risk reduction. In terms of the value of a statistical life, our results are...

We estimate the value of a 'blip', i.e. an immediate small reduction, in the hazard rate for a random sample of Swedes. Since the risk reduction is age-independent (2 'extra saved lives' out of 10,000 during the next year), we can examine how the value of a statistical life varies with age. We...

To estimate the discount rate for lives saved in the future a number of studies have been carried out on the trade-off between saving lives now and in the future. A telephone survey is administered to about 1,700 individuals to test if the framing of the question affects the estimated trade-off....

This study reports an attempt to measure the value of an increased survival probability at advanced ages. It turns out that the average willingness to pay for a program which would increase the expected length of life by one year, conditional on having survived to the age of 75 years, is lower...
