Abstract

Many rights-based systems in fisheries use individual fishing quotas (IFQs) that allocate shares of total allowable catch to individual fishers, vessels, or groups of fishers. We analyze the performance of IFQs in the Norwegian coastal groundfish fisheries that substantially limit transferability. We use data from two similar fishing groups that were treated with different management. Difference-in-differences results show that IFQs increase productivity and prices for some of the main groundfish species. Results suggest that expected productivity gains and price gains from first-best rights-based policies that create highly transferable IFQs can result from second-best policies that substantially limit transferability.

个人捕鱼配额的经济收益:挪威沿海底层鱼类渔业
许多以权利为基础的渔业系统使用个体捕捞配额(IFQs),将总可捕量的份额分配给个体渔民、渔船或渔民群体。我们分析了挪威沿海底层鱼类渔业中大幅限制可转让性的 IFQ 的表现。我们使用的数据来自两个类似的捕捞群体,它们受到不同的管理。差分结果显示,IFQ 提高了一些主要底层鱼类的生产率和价格。结果表明,建立高度可转让的 IFQ 的基于权利的第一最优政策的预期生产率收益和价格收益可能来自大幅限制可转让性的第二最优政策。
