Exploring the Effects of Attribute Translation on Scope Sensitivity in Contingent Valuation: The Case of Seabed Marine Debris Removal
摘要
This paper tests whether presenting environmental program attributes in absolute versus relative numerical terms affects scope sensitivity, through a split-sample experiment in an original contingent valuation study for removing derelict fishing gear from Norwegian coastal waters. Results are mixed but indicate slightly lower scope sensitivity under relative framing. It also reports notable willingness to pay (WTP), as a one-time tax, for two partial and a full clean-up intervention of 100 km 2 of seabed. The paper highlights how subtle survey design choices can influence stated preferences and contributes to a scarce empirical base of welfare estimates for seabed marine debris removal.
中文摘要
本文通过在挪威沿海水域清除废弃渔具的原创条件价值评估研究中开展分样本实验，检验以绝对数值与相对数值形式呈现环境项目属性是否会影响范围敏感性。结果并不一致，但表明在相对框架下范围敏感性略低。本文还报告了为对100平方公里海床实施两项部分清理干预和一项全面清理干预而支付的一次性税收的显著支付意愿（WTP）。本文强调了细微的调查设计选择如何影响陈述性偏好，并为海床海洋垃圾清除的福利估计这一稀缺实证基础作出了贡献。
