This paper shows a contingent valuation exercise of pollution abatement in remote lakes. In addition to estimating the usual interval data model, it applies a point and interval statistical approach allowing for uncensored data, left-censored data, right-censored data and left- and right-censored data to explore the determinants of willingness-to-pay in a payment card survey. Results suggest that the estimations between models may diverge under certain conditions.
本文展示了一项针对偏远湖泊污染减排的条件价值评估实践。除了估计常用的区间数据模型外，本文还应用了点和区间统计方法，允许使用无删失数据、左删失数据、右删失数据和左、右删失数据，以探讨支付卡调查中意愿支付的决定因素。结果表明，在某些条件下，模型之间的估计可能会出现差异。
