在考虑非市场商品的选择实验设置中，本文通过提供证据表明在收集受访者样本反馈时互联网调查可以成为传统邮件调查的可行替代方案，从而补充了有关调查模式影响的文献。该案例研究涉及在丹麦修建新高速公路时保护不同类型景观免受道路侵占的偏好。对两份受访者样本进行了调查——一份通过互联网，一份通过邮件。通过六种不同的标准对两个样品的性能进行比较；响应率、抗议响应、人口统计、偏好和支付意愿、估计精度，以及最后的选择确定性。其中一些标准存在差异，这意味着分析师应该意识到选择互联网而不是邮件可能会伴随调查模式效应。然而，观察到的差异并不会转化为无条件支付意愿估计值的显着差异。在大多数非市场商品的应用经济评估研究中，主要目标实际上是对支付意愿的估计。因此，在目前的情况下，所确定的调查模式的影响并没有严重削弱互联网作为收集数据以进行非市场商品选择实验经济评估的合适手段的适用性和持续使用。
In a choice experiment setup considering a non-market good, this paper adds to the literature on survey mode effects by providing evidence that internet surveys can be a viable alternative to traditional mail surveys when gathering feedback from a sample of respondents. The case study concerns preferences for protecting different types of landscape from road encroachment when building new motorways in Denmark. Two samples of respondents are surveyed—one by internet and one by mail. The performances of the two samples are compared over six different criteria; response rates, protest responses, demographics, preferences and WTP, estimation precision, and, finally, certainty in choice. Differences are observed for some of these criteria, implying that analysts should be aware that choosing internet over mail could be accompanied by a survey mode effect. However, the observed differences do not translate into significant differences in the unconditional WTP estimates. In most applied economic valuation studies of non-market goods, the main objective is in fact estimation of WTP. Hence, in the present case, the identified survey mode effects do not severely invalidate the applicability and continued use of the internet as a suitable means of collecting data for choice experiment economic valuation of non-market goods.
