Quality over Quantity: Nonmarket Values of Restoring Coastal Dunes in the U.S. Pacific Northwest
通过选择实验研究公众对海岸沙丘生态恢复的偏好，发现提高恢复质量比扩大恢复面积带来更大的福利收益，且公众偏好保持休闲可达性。
We design a choice experiment to examine public preferences for coastal dune ecosystem restoration in the U.S. Pacific Northwest. Dunes are a public good whose natural state is now rare. Respondents are asked to choose among hypothetical projects that vary by project size, restoration quality, recreation access, flooding risk, and cost. Restoration quality is defined as closeness to the natural ecosystem. We find that increasing restoration quality results in significantly higher welfare gains than increasing the size of restoration area. Maintaining recreation access is preferred, and programs with recreation restrictions yield positive willingness to pay only if accompanied by the highest restoration quality.
