This paper investigates the idea that people are unsure about the value they place on prospective changes in environmental goods. In particular, we focus on a parametric explanation of the determinants of a "value gap," the difference between the most someone is sure they would pay for an...

Stated preference studies tell respondents that policies create environmental changes with varying levels of uncertainty. However, respondents may include their own a priori assessments of uncertainty when making choices among policy options. Using a choice experiment eliciting...

We attempt a first combination of the participatory technique known as the "citizens’ jury" with choice modelling, a stated-preference technique increasingly favored by environmental economists. Our application is conducted in the context of water quality improvements under the Water Framework...

This paper considers the use of a "combinatorial optimization" technique in the aggregation of environmental benefit values. Combinatorial optimization is used to statistically match population census data to a contingent valuation survey. The matched survey and census information is then used...

This paper is concerned with policies for the supply of public, environmental goods from the farm sector. In particular, we characterize the buying of these goods by the public from farmers using the "Provider Gets Principle." This principle is well established in OECD countries, as we...

Policymakers are increasingly making use of benefits transfer in benefit-cost assessments of environmental policy. An important question is how big the resultant errors are, and how sensitive errors are to how the transfer is conducted. We employ a choice experiment focusing on landscape...

Protected areas are employed worldwide as a means of conserving biodiversity. Unfortunately, restricting access to such areas imposes opportunity costs on local people who have traditionally relied on them to obtain resources such as fuelwood and bushmeat. We use contingent valuation to estimate...

This paper reevaluates federal allocation decisions to protect 241 endangered vertebrates between 1993 - 1996. We control for the time invariant species characteristics to address species heterogeneity bias. The results suggest that yearly variation in variables like endangerment rankings and...

Self-protection has been used to help define lower bounds on the value of statistical life (VSL). We show circumstances exist in which (1) the lower bounds are so low as to be more misleading than informative; and (2) the bound is an upper bound on the population’s average VSL. The relationship...
