Contingent valuation in health care: does it matter how the ‘good’ is described?
通过对104名澳大利亚受访者的调查，研究在条件估值中描述健康状况的叙事长度和标签对支付意愿的影响，发现详细叙事和不同标签会显著改变估值结果。
A general population sample of 104 Australian respondents completed an interviewer-administered contingent valuation (CV) survey that asked them to value five scenarios representing the same core improvement in health status. These scenarios varied only in the degree of narrative used to describe the condition causing the health problem being valued and labeling of this health problem. Results indicate no significant difference in willingness to pay (WTP) between expressing symptoms as a brief or moderate narrative, but a significantly lower WTP value when expressed in an extensive narrative. WTP also differed significantly according to condition 'labels'. Possible implications for CV research are outlined.
