Rt. Carson et al., REFERENDUM DESIGN AND CONTINGENT VALUATION - THE NOAA PANELS NO-VOTE RECOMMENDATION (VOL 80, PG 335, 1998), Review of economics and statistics, 80(3), 1998, pp. 484-487
This paper considers the effects for offering a ''would-not-vote'' opt
ion in contingent valuation (CV) questions framed using the referendum
format. This approach arises from a suggestion made by the National O
ceanic and Atmospheric Administration's (NOAA) panel on contingent val
uation. The NOAA panel was asked to evaluate the use of this method fo
r estimating the economic value of nonmarketed environmental resources
in the context of natural resource damage assessments. This test used
the CV questionnaire developed for the study of the Exxon Valdez oil
spill conducted by the State of Alaska with in-person interviews. The
findings suggest that when those selecting the ''would-not-vote'' resp
onse are treated as having voted ''against'' the program (a conservati
ve coding), offering this option does not alter (1) the distribution o
f ''for'' and ''against'' responses (2) the estimates of willingness t
o pay derived from these choices, or (3) the construct validity of the
results.
