Revealed preference valuation compared to contingent valuation: radon‐induced lung cancer prevention
比较揭示偏好和条件估值两种经济估值方法在氡致肺癌预防中的应用，发现单界条件估值与主观揭示偏好估计的置信区间重叠，表明两者具有外部有效性。
This paper explores and compares two tools of economic valuation, revealed preference and contingent valuation, with the purpose of ultimately informing the use of two methods of economic evaluation, CEA and CBA. The valuation methods are applied to empirical data for radon-induced lung cancer prevention. However, only the single bound CV and the subjective revealed preference estimates have overlapping confidence intervals, indicating that they do have external validity as assessed by convergent validity. The revealed preference subjective risk valuation was (180 pounds sterling (144 pounds sterling, 247 pounds sterling)) and the single bounded contingent valuation estimate was (269 pounds sterling (201 pounds sterling, 343 pounds sterling)).
