- 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 also show how blip data can be used to obtain a lower bound for the value of a permanent change in an individual's hazard rate. The value of a life exhibits an inverted-U shape with respect to age, peaking at the age of 40, and lies within the $3 to $7 million interval where most reasonable estimates are clustered according to Viscusi's (1992) survey.

A Dynamic Model of Biodiversity Preservation
- 1998
-
In: Environment and Development Economics. - : Cambridge University Press. ; 3, s. 157-172
-
Journal article (peer-reviewed)abstract
- This paper attempts to develop a dynamic model of optimal biodiversity preservation in a stylized ecosystem. Species richness (number of species) is used as a measure of diversity and its interactions with the resource stock, consumptive extraction and pr
