Individual Vessel Quotas and Increased Fishing Pressure on Unregulated Species
研究了渔业管理中个别船只配额制度如何导致渔民增加对未管制物种的捕捞压力，利用约束利润函数建模，并以挪威围网渔船为例进行实证分析。
<i>When individual vessel quotas are used in fisheries management, quotas are set species by species, in most cases. Often, it is only the most important of the target species that are regulated by quota. There is a growing concern that the introduction of individual vessel quotas leads to increased fishing pressure on unregulated species. To model the behavior of fishermen with this regulatory structure, a constrained profit function is used, where the quota species are treated as fixed, while the unregulated species are variable. An empirical analysis is provided for Norwegian purse seiners.</i>
