This research provides a benefit transfer model of willingness-to-pay (WTP) for wetlands' conservation in the United States. The validity of the estimated wetland's willingness-to-pay values is also examined. This study extends and provides improvements to wetlands valuation literature by using information obtained from 21 study sites - 19 natural and 2 constructed. Benefit transfer values for wetlands are imputed to six policy wetland sites - 5 natural and 1 constructed. Regression results are reported for one of eight models estimated and examined with four validity tests. Based on these tests, transfer error adjustments of WTP estimates for policy sites are reported.

美国湿地保护支付意愿的收益转移估计

本研究为美国湿地保护提供了一种支付意愿（WTP）的利益转移模型。还检验了估计湿地支付意愿值的有效性。本研究使用从 21 个研究地点（19 个自然地点和 2 个人工地点）获得的信息，扩展并改进了湿地估值文献。湿地的利益转移价值被估算到六个政策湿地地点 - 5 个自然湿地和 1 个人工湿地。报告了八个模型之一的回归结果，估计和检查了四个有效性测试。基于这些测试，报告了政策站点 WTP 估计的转移误差调整。
