Dichotomous choice willingness to pay questions are often used to determine the value visitors place on nature-based recreation. Ambiguity in wording can result in the use of information that does not necessarily reflect visitors’ true WTP. For example, depending on the specificity of the...

Past empirical benefit measures and other information originally obtained through primary data collection can be used for assessing and analyzing current management and policy actions. This use of past valuation information for current policy analysis is called benefit transfer. In this report,...

The Orbit demand model allows the magnitude of the calibration to stated purchase intentions to vary based on the magnitude of the stated quantities. Using an empirical example of stated trips, we find that the extent of calibration varies substantially with less correction needed at small...

In some, but not all, contexts, respondents to stated preference valuation studies state a willingness to pay (WTP) higher than what lab or field experiments indicate is the actual amount they would pay. However, several ex ante survey design strategies and ex post calibration techniques can be...

A method of paired comparison is adapted for use in estimating economic measures of value. The method elicits multiple binary choices for paired items in a choice set. Probability distributions and economic values are estimated nonparametrically and parametrically. The method is applied in an...

Recent efforts to refine the concept of existence value and to empirically measure it has led to an unnecessary narrowing of the concept of existence value. This paper uses the literature on public goods to argue that existence value is a much broader concept than proposed by several authors....

Combining stated and revealed preference data often involved multiple responses from the same individual. Panel estimators are appropriate to jointly model the decision to actually visit at current trip costs, the intention to visit at hypothetically higher trip costs, and the intention to visit...

This paper develops a statistically unbiased and simple method for measuring the difference of independent empirical distributions estimated by bootstrapping or other simulation approaches. This complete combinatorial method is compared with other unbiased and biased methods that have been...

This research updates the joint estimation of revealed and stated preference data of Cameron (1992) to allow for joint estimation of the Travel Cost Method (TCM) portion using count data models. Further these count data models reflect correction for truncation and endogenous stratification...
