摘要

我们比较了概率样本和两个非概率样本(MTurk和qualics)的水质评估结果。这些样本在一些关键的人口统计数据上有所不同，但衡量出来的态度却惊人地相似。对于估值模型，大多数参数在样本之间存在显著差异，但许多边际支付意愿在样本之间是相似的。值得注意的是，对于非边际变化，不同样本之间存在一些差异:MTurk值总是显著大于概率样本，对于大约20%改进的变化，Qualtrics值也是如此。总的来说，证据是混杂的，样本之间有一些关键的差异，但也有许多相似之处。

Comparing water quality valuation across probability and non-probability samples

We compare water quality valuation results from a probability sample and two opt-in non-probability samples, MTurk and Qualtrics. The samples differ in some key demographics, but measured attitudes are strikingly similar. For valuation models, most parameters were significantly different across samples, yet many of the marginal willingness to pay were similar across samples. Notably, for non-marginal changes there were some differences by samples: MTurk values were always significantly greater than the probability sample, as were Qualtrics values for changes up to about a 20% improvement. Overall, the evidence is mixed, with some key differences but many similarities across samples.
