Managing Multiple Activities in a National Park
运用俱乐部物品理论推导国家公园内多种活动（如游憩和荒野保护）的管理效率条件，分析用户收费、自筹资金和活动禁止的启示，并以冰川国家公园为例说明理论应用所需信息。
This paper uses the theory of club goods to derive efficiency conditions for managing multiple activities in a national park. The park jointly provides recreational activities for visitors and wilderness, a pure public good. The implications for user fees, self-financing of the park, and prohibition of particular activites are derived. Separate tolls should be charged for each activity; with efficient activity tolls, no entrance fee is needed. Glacier National Park is used to show that, in order to apply the theoretical rules, park managers need more information than is currently available.
