A simple but novel experiment is described examining the impact of interviewer appearance upon stated willingness to pay (WTP) for an environmental good. This test consists of an interviewer wearing either formal or more casual clothing. This analysis is interacted with a cross cutting treatment...

Given the evidence against the unitary model of the household, there is a need to understand the predictions of alternative household models within the context of valuation. This paper derives the relationship between household and individual willingness to pay (WTP) for the non-cooperative...

Previous literature has found that politically conservative individuals express a lower willingness-to-pay (WTP) for environmental goods than left-wing supporters. Using data from three surveys valuing water we investigate the role of context by evaluating whether the means of provision (public...

We argue that the literature concerning the valuation of non-market, spatially defined goods (such as those provided by the natural environment) is crucially deficient in two respects. First, it fails to employ a theoretically consistent structural model of utility to the separate and hence...

We present an experiment designed to investigate the presence and nature of ordering effects within repeated response stated preference studies. We formulate a general structural model of such effects and use this to isolate signature patterns for position-dependent effects (learning about...

We develop and test guidance principles for benefits transfers. These argue that when transferring across relatively similar sites, simple mean value transfers are to be preferred but that when sites are relatively dissimilar then value function transfers will yield lower errors. The paper also...
