使用规定的选择实验来调查居住在魁北克省的农村居民对水质改善的经济评价。在魁北克省，农村居民在制定更严格的环境法规方面发挥了重要作用。与大多数关于评估水质改善的选择实验不同，本研究明确考虑了选择实验设计和分析中的风险。磷和大肠菌减少的风险是通过选择集中的三点均匀分布引入的。结果表明，与恒定的相对风险厌恶偏好相比，对恒定绝对风险厌恶偏好的支持更大。农村居民重视大肠菌群和磷的减少，受教育程度较高的人特别愿意看到政府向农民和纳税人征税以确保减少。随着科学技术的进步和水质结果风险的降低，以及非农业农村居民政治影响力的增加，政府应该更容易用污染者付费计划取代自愿成本分摊计划。
Stated choice experiments are used to investigate the economic valuation of rural residents living in the province of Quebec for water quality improvements. In Quebec, rural residents played an important role in the setting of stricter environmental regulations. Unlike most stated choice experiments about the valuation of improvements in water quality, this study explicitly accounts for risk in the design and analysis of choice experiments. Risk in phosphorus and coliform reductions is introduced through a three-point uniform distribution in the choice sets. The results show greater support for constant absolute risk aversion preferences than for constant relative risk aversion. Rural residents value coliform and phosphorus reductions and the more educated ones are particularly willing to see the government tax farmers and taxpayers to secure such reductions. As the science improves and risk in water quality outcomes decrease and as the political weight of non-farm rural residents increase, it should be easier for governments to replace voluntary cost-share programs by polluter-payer programs.
