Contingent Valuation and Incentives
通过实验比较三种支付机制（个人捐款、有门槛捐款和公投）对条件估值中支付意愿的影响，发现公投机制比个人捐款产生更多肯定回答，并检验了各机制的相对可信度。
ABSTRACT. We empirically investigate the ef-fect of the payment mechanism on contingent val-ues by asking a willingness-to-pay question with one of three different payment mechanisms: indi-vidual contribution, contribution with provision point, and referendum. We nd statistical evi-dence of more af rmative responses in the refer-endum treatment relative to the individual contri-bution treatment, some weak statistical evidence of more af rmative responses in the referendum treatment relative to the provision point treat-ment, and no statistical evidence of more af r-mative responses in the provision point treatment relative to the individual contribution treatment. The relative credibility of the three payment mechanisms is also examined. I.
