Under conditions of risk it makes a difference whether the discount rate is determined as an expected present or as an expected future value. This difference which is dubbed as the Weitzman-Gollier puzzle has stimulated an intensive discussion which, however, is somewhat confusing. In this paper...

It is not immediately clear how to discount distant-future events, like climate change, when the distant-future discount rate itself is uncertain. The so-called “Weitzman-Gollier puzzle” is the fact that two seemingly symmetric and equally plausible ways of dealing with uncertain future...

The efficient rate of return of a zero-coupon bond with maturity <i>t</i> is determined by our expectations about the mean (+), variance (-) and skewness (+) of the growth of aggregate consumption between 0 and <i>t</i>. The shape of the yield curve is thus determined by how these moments vary with <i>t</i>. We...

Weitzman (1998) showed that when future interest rates are uncertain, using the expected net present value implies a term structure of discount rates that is decreasing to the smallest possible interest rate. On the contrary, using the expected net future value criterion implies an increasing...

Consider a public project which produces a consumption good and which benefits future generations. Let a conventional cost-benefit analysis find that it gives higher benefits than projects it would dis-place in the private sector. Voters may nevertheless oppose the public project: the...

This paper discusses a novel approach to elicit people’s preferences for public goods, namely the life satisfaction approach. Reported subjective well-being data are used to directly evaluate utility consequences of public goods. The strengths of this approach are compared to traditional...

This paper argues for an alternative methodology to estimate the value of risk to life. By relaxing the assumption of additive separability, we introduce risk aversion with respect to the length of life and show that the extended model better fits available data. This is crucial for the...

Inhabitants of houses near Amsterdam Airport are complaining of noise nuisance, caused by aircraft traffic. The usual assumption is that the effect of the externality will be perfectly reflected by house price differentials. This is based on the implicit assumption that there is a...

That climate policies are costly is evident and therefore often creates major fears. But the alternative (no action) also has a cost. Mitigation costs and damages incurred depend on what the climate policies are; moreover, they are substitutes. This brings climate policies naturally in the realm...

In many countries environmental policies and regulations are implemented to improve environmental quality and thus individuals’ well-being. However, how do individuals value the environment? In this paper, we review the Life Satisfaction Approach (LSA) representing a new non-market valuation...
