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...

This paper presents a simple computational method for measuring the difference of independent empirical distributions estimated by bootstrapping or other resampling approaches. Using data from a field test of external scope in contingent valuation, this complete combinatorial method is compared...

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...

A combined telephone contact-mail booklet-telephone interview of California and New England households regarding their willingness to pay for fire management in California and Oregon's old-growth forests was performed to test hypotheses regarding the spatial extent of the public goods market....
