Ij. Bateman et Ih. Langford, NONUSERS WILLINGNESS-TO-PAY FOR A NATIONAL-PARK - AN APPLICATION AND CRITIQUE OF THE CONTINGENT VALUATION METHOD, Regional studies, 31(6), 1997, pp. 571-582
A great deal of the ongoing academic debate concerning the contingent
valuation (CV) method has focused upon whether or not the method is su
itable for assessing non-use values. This paper presents results from
a study examining non-users' Values for preserving the Norfolk Broads,
a wetland area of recognized international importance, from the threa
t of saline flooding. Discussion of results centres upon the validity
of the CV method for eliciting unbiased estimates of non-use value. A
graphical representation of findings from a variety of studies is pres
ented to suggest that such results are logically ordered across goods
and valuation scenarios. However, as the paper concludes, logicality a
nd validity are not necessarily synonymous.
