Willingness-to-pay (WTP) responses from dichotomous choice contingent valuation studies are often modeled using logistic regression, from which estimates of mean or median WTP are calculated. However, a great many factors influence an individual's WTP, some of which may be unobserved. Hence, the...

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...
