Restoring a Fish Stock: A Dynamic Bankruptcy Problem
研究了两种总允许捕捞量分配规则(比例规则与约束等额奖励规则)对鱼类种群恢复、捕捞量和盈利性的影响,为渔业管理者选择公平有效的配额方案提供参考。
Total Allowable Catch (TAC)-regulating schemes have been introduced in most fisheries. TAC distribution following the Proportional Rule, based on historical catches, implies that harvesters or vessel groups that have captured more in the past and contributed to overfishing are getting larger quotas than groups that have contributed less to overfishing. In contrast to this rule, a more egalitarian rule, the Constrained Equal Award Rule, is proposed for distributing the TAC. Contingent upon the fishing techniques used by the harvesters, it is demonstrated how the fish-stock recovery period, harvest, and profitability may vary according to these two rules. <i></i>
