人们的支付意愿值可能会受到各种影响（例如假设的偏见）的夸大，这意味着陈述的偏好有效性测试仍然相关。最近开发的推断估值方法可能有助于识别和/或减少夸大的陈述偏好值。然而，推断估值方法的经济应用在文献中相对有限，证据仍然是混合的。本文研究了越南湄公河三角洲地区农民为盐碱入侵缓解项目支付费用的意愿，采用了传统的或有评估方法和推断评估方法。推断出的估值估计值比传统的支付意愿估计值低31%，各集团的估值平均低24%左右。我们讨论了这些发现，以及承诺成本和提供点机制支付工具可能发挥的作用。本文还概述了未来减轻盐度入侵计划对公共政策的影响。
People's willingness-to-pay values may be inflated by a variety of influences (e.g. hypothetical bias), which means that stated preference validity tests remain relevant. Recently developed inferred valuation approaches may serve to identify and/or reduce inflated stated preference values. However, economic applications of inferred valuation approaches are relatively limited in the literature, and the evidence remains mixed. This paper examines farmers' willingness-to-pay for salinity intrusion mitigation programs in the Mekong River Delta of Vietnam using both conventional contingent and inferred valuation approaches. Inferred valuation estimates were as much as 31 per cent lower than conventional estimates of willingness-to-pay, and averaged about 24 per cent lower across the groups. We discuss these findings, and the role that commitment costs and provision point mechanism payment vehicles may play. Public policy implications for any future salinity intrusion mitigation program are also outlined.
