英文文献：A Spatial Model of Dolphin Avoidance in the Eastern Tropical Pacific Ocean-热带太平洋东部海豚躲避的空间模型

英文文献摘要：
This paper examines the impact of dolphin-safe eco-labeling and how it fundamentally altered the spatial distribution of fishing effort and fishermen's willingness to pay to avoid dolphins. To do this, a dynamic discrete choice econometric model is applied to the Eastern Tropical Pacific tuna fishery. This econometric approach combines a dynamic programming component with the static discrete site choice model. This estimator couples the current period projected profits associated with fishing a specific site with the value of all future location choices on the cruise, assuming choices are made optimally. The key feature of this model is that it recovers behavioral parameters and solves the dynamic programming problem recursively. The dynamic site choice model reveals a markedly higher impact on producers as compared to the commonly used static model following the labeling regime. Further, in all but a few cases the common practice in dynamic choice models of setting discount factors equal to one is rejected.
这篇论文探讨了海豚安全生态标签的影响，以及它如何从根本上改变了捕鱼努力的空间分布，以及渔民为避免海豚而花钱的意愿。为此，将动态离散选择计量模型应用于东热带太平洋金枪鱼渔业。这种计量经济学方法结合了动态规划和静态离散选址模型。假设选择是最优的，该估算器将当前与特定地点捕鱼相关的预期利润与邮轮未来所有地点选择的价值结合起来。该模型的主要特点是能够恢复行为参数并递归求解动态规划问题。与标签制度下常用的静态模型相比，动态站点选择模型对生产者的影响显著更高。此外，除了少数情况外，在动态选择模型中设置折现因子等于1的常见做法都被拒绝。
