英文文献摘要：
A stated choice model is used to estimate wetland mitigation preferences. In a split sample mail survey, a main effects design is compared to a randomized design. Although randomized designs estimate main effects less efficiently, several policy relevant interactions were found to be significant, suggesting some merits of randomized designs.

一个既定的选择模型被用来估计湿地缓解偏好。在拆分邮件调查样本中，将主效应设计与随机设计进行比较。尽管随机设计估计主要影响的效率较低，但一些与政策相关的交互作用被发现是显著的，这表明了随机设计的一些优点。
