In models with unobserved taste heterogeneity, distributional assumptions can be placed in two ways: (1) by specifying the distribution of coefficients in the utility function and deriving the distribution of willingness to pay (wtp), or (2) by specifying the distribution of wtp and deriving the...

Stated choice experiments about ecosystem changes involve complex information. Thisstudy examines whether the format in which ecosystem information is presented torespondents affects stated choice outcomes. Our analysis develops a utility-maximizingmodel to describe respondent behavior. The...

Stated preference analyses commonly impose strong and unrealistic assumptions in response to spatial welfare heterogeneity. These include spatial homogeneity or continuous distance decay. Despite their ubiquity in the valuation literature, global assumptions such as these have been increasingly...

To assess demand for non-market goods, researchers must sometimes resort to direct elicitation of consumer tradeoffs with the use of surveys. Stated preference (SP) methods typically involve surveys of consumers wherein choice scenarios are posed to respondents and individuals are asked to...

Overall wine consumption in Spain is decreasing while, at the same time,Designation of Origin (DO) wine consumption is increasing gradually. This studyexamines Spanish DO wine consumer behaviour through stated preferences (SP) andrevealed preferences (RP) data. Part-worth utilities are...

Although mixed logit models are common in stated preference applications, resulting welfare estimates can be sensitive to minor changes in specification. This can be of critical relevance for policy and welfare analysis, particularly if policymakers are unaware of practical implications. Drawing...

Vaccines against several common foodborne pathogens are being developed and could substantially alter the policy tools available to address foodborne illness. However, little analysis is available to suggest how social welfare would be affected by these new vaccines. To address this void, we use...

In this article we present results from a study of recreation demandfor southern North Carolina beaches. We combine revealed preference andstated preference data in order to estimate the changes in recreation demandthat might occur with beach nourishment and parking improvements necessaryto...

Individuals are widely believed to overstate their economic valuation of a good by a factor of two or three. This paper reports the results of a meta-analysis of hypothetical bias in 28 stated preference valuation studies that report monetary willingness-to-pay and that used the same mechanism...

In the absence of markets for environmental quality, researchers resort to stated and revealed preference techniques to estimate the benefits of environmental programs. One of the most widely used revealed preference approaches is hedonic property value models, where the value of an...
