When applying willingness-to-pay (WTP) in economic evaluations, there have been strong theoretical arguments for the use of ex ante insurance-based questions, which can be framed either as insurance premiums or taxation contributions. This paper suggests theoretical reasons why respondents may value a programme differently in these two different ex ante approaches, and inquires empirically into the potential existence of such differences. A split-sample interview study was undertaken in Denmark. The proportion of respondents willing to pay is higher in the community version, and the respondents use different reasons for being and not being willing to pay.
在经济评估中应用支付意愿（WTP）时，对于使用事前基于保险的问题存在强有力的理论依据，这些问题可以表述为保险费或税收贡献。本文提出了理论原因，解释为什么受访者在这两种不同的事前方法中可能对一个项目的估值不同，并对这种差异的潜在存在进行了实证研究。在丹麦进行了一项分样本访谈研究。在社区版本中愿意支付的受访者比例更高，并且受访者对于愿意支付和不愿意支付给出了不同的理由。
