Exposure to chemicals has been shown to reduce IQ in children. In turn, a person’s IQ is likely to affect their educational achievements, which may then affect lifetime earnings, more generally, a person’s quality of life. At the same time, authorities face challenges in regulating chemical...

The contingent valuation method for estimating willingness to pay for public goods typically adopts a single referendum question format, which is relatively statistically inefficient. As an alternative, Cooper, Hanemann, and Signorello (2002) propose the one-and-one-half bound (OOHB) format,...

This paper uses recently developed statistical techniques to achieve improved parameter estimates from models of dichotomous choice contingent valuation data. Random effects associated with bid amounts presented to respondents are modelled alongside the variance of individual responses, to give...

The contingent valuation method for estimating willingness to pay for public goods typically adopts a single referendum question format which is statistically inefficient. As an alternative, Cooper, Hanemann and Signorello (2002) propose the 'one-and-one-half bound' (OOHB) format allowing...

We present the results of a ‘natural experiment’ to test how variations in exogenous risk levels affect resultant willingness to pay (WTP) for risk reduction. The case study presented considers WTP for reductions in the skin cancer risks associated with exposure to solar UV radiation. A...

Although dichotomous choice (DC) contingent valuation (CV) has been recommended by the US NOAA 'blue-ribbon' panel for large-scale contingent valuation studies, useful information can still be obtained from smaller, open-ended (OE) studies, often undertaken as a precursor to a DC survey. The CV...

The contingent valuation method is often used for valuing environmental goods which have nonuse as well as direct-use values. However, it is often not clear how respondents to a contingent valuation survey allocate values when asked for willingness-to-pay amounts. In this paper, we investigate...
