ABSTRACT. Interval data analysis of CV discrete choice responses delivers efficiency gains which must be weighed against the risk of introducing strategic response bias. Efficiency gains are also achievable by improved bid design. We assess these gains on median WTP estimates first in an...

While a dominated choice involves a situation in which one option clearly dominates another on all relevant dimensions, an asymmetrically dominated choice typically arises where at least two options do not dominate each other and one (but not both) of those options does dominate a third option....

Using equivalent loss (the monetary loss equivalent to a proposed amenity reduction, EL) and equivalent gain (the gain equivalent to a proposed amenity increase, EG) alongside traditional welfare measures in a contingent valuation study of traffic disamenity, we report an experiment designed to...

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...

This paper considers the use of contingent valuation to estimate non-market benefits from separately valued nested goods. Survey respondents were asked referendum WTP questions regarding either a scheme to protect the “whole” area of a wetland or a scheme to protect some nested “part”...

The paper presents a variety ofmeta analysis models of woodland recreation benefit estimates, contrasting conventionally estimatedmodelswith those provided by novel, multi-level modeling (MLM) techniques (Goldstein 1995). Our conventional models suggest that studies carried out by certain...

A split sample experiment is conducted to test one of the most fundamental assumptions underpinning choice experiments in an environmental setting: whether stated values are absolute or relative. The test uses a natural experiment involving respondents at different home locations relative to...
