Use, option and externality values: are contingent valuation studies in health care mis‐specified?
通过对澳大利亚居民进行条件价值评估调查，发现包含外部性和选择价值的场景估值显著高于仅使用价值，质疑健康领域现有研究可能因忽略这些价值而存在设定偏误。
A general population sample of Australian respondents completed a contingent valuation (CV) survey that asked them to value six scenarios. These varied according to whether the scenario was seeking to elicit: (i) use value; (ii) externality value; (iii) option value; or (iv) a combination. Results indicate that use plus externality and/or option value was significantly greater than use value alone. As CV studies in health (care) overwhelmingly focus on use value alone - often implicitly through study design rather than explicitly - this raises the possibility of mis-specification in CV research in health (care). The implications for CV in health (care) are considered.
