A dichotomous-choice contingent-valuation survey was conducted in the State of Louisiana (USA) to estimate compensating surplus (CS) and equivalent surplus (ES) welfare measures for the prevention of future coastal wetland losses in Louisiana. Valuations were elicited using both willingness to pay (WTP) and willingness to accept compensation (WTA) payment vehicles. Mean CS (WTP) estimates based on a probit model using a Box-Cox specification on income was $825 per household annually, and mean ES (WTA) was estimated at $4444 per household annually. Regression results indicate that the major factors influencing support for land-loss prevention were income (positive, WTP model only), perceived hurricane protection benefits (positive), environmental and recreation protection (positive), distrust of government (negative), age (positive, WTA model only), and race (positive for whites).
在美国路易斯安那州进行了一项二项选择意愿调查，以估计预防路易斯安那州未来沿海湿地损失的补偿盈余（CS）和等效盈余（ES）福利措施。使用支付意愿（WTP）和接受补偿意愿（WTA）支付工具来得出评估值。基于 Box-Cox 规范对收入进行的概率模型得出的 CS（WTP）均值估计值为每户每年 825 美元，ES（WTA）的均值估计值为每户每年 4444 美元。回归结果表明，影响土地损失预防支持的主要因素是收入（正，仅 WTP 模型）、感知的飓风保护效益（正）、环境和娱乐保护（正）、对政府的不信任（负）、年龄（正，仅 WTA 模型）和种族（白人正）。
