Abstract
This paper introduces an alternative non-market value elicitation method—the “quasi-doublereferendum”
(QDR)—applied to barrier island restoration in Mississippi. It is appropriate for
surveys that elicit willingness-to-pay responses to multiple projects differing in scale only and can
be used to increase efficiency while mitigating bias. We compare results to the more commonly
used single-referendum (SR) method under two admissible ranges of willingness to pay: negative
to positive infinity, and zero to income. The confidence intervals of the QDR models were
narrower. We argue that the QDR approach should be less subject to bias than the commonly
used double-referendum approach.
