Is Referendum the Same as Dichotomous Choice Contingent Valuation?
通过专门设计的条件估值调查，发现明确提及公投时估计的支付意愿显著高于不提及投票过程的二分选择问题，对条件估值法的设计有参考价值。
The NOAA Panel on contingent valuation (Arrow et al. 1993) recommends that the valuation question be cast under the form of a referendum because of incentive properties and familiarity to the respondent. Even though the literature has generally accepted the panel recommendation, it is not clear whether explicitly mentioning a referendum leads to different values than asking a dichotomous (yes/no) question without mentioning any voting process. The results of our specifically designed contingent valuation survey indicate that the estimated willingness to pay is significantly larger when a referendum is explicitly mentioned.
