Valuing the Loss of Rock Climbing Access in Wilderness Areas: A National-Level, Random-Utility Model
研究利用攀岩旅行数据构建随机效用模型，评估美国林务局禁止在荒野地区使用固定保护装置的提案对攀岩者造成的经济损失，发现该提案可能构成重大监管变化。
<i>Given potential growth in outdoor rock climbing and its concentration on public lands, the management of climbing access in wilderness areas is an issue of considerable national controversy in the United States. A proposed rule change by the U.S. Forest Service (USFS) would prohibit the use of fixed climbing protection in wilderness areas—effectively eliminating safe access to many sites. Using a unique data set on rock climbing trips, a repeated-nested logit, random-utility model is used to analyze economic losses to climbers resulting from the USFS proposal. Results indicate that the USFS proposal may constitute a major regulatory change.</i>
