A Repeated Mixed Logit Approach to Valuing a Local Sport Fishery: The Case of Southeast Alaska Salmon
用重复混合Logit模型估计阿拉斯加东南部一日游私人船钓王鲑和银鲑的钓鱼机会价值及捕捞率变化价值，发现钓鱼者时间影子价值并非工资的固定比例，每次钓鱼选择机会平均价值约45美元，每条王鲑和银鲑的边际价值分别约71美元和106美元。
We estimate the values of fishing opportunities and changes in harvest rates for single-day private boat saltwater fishing for king and silver salmon in southeast Alaska, using a repeated mixed logit model of trip frequency and distribution estimated jointly with anglers’ shadow values of time. The standard assumption that the shadow value of time is a fixed fraction of the angler’s wage is rejected in favor of a more flexible model. The mean value of a fishing choice occasion is approximately $45 per angler, and mean marginal values of a king salmon and a silver salmon are approximately $71 and $106. <i></i>
