Abstract

We evaluate whether changes in geographic distribution of landings coincided with implementation of individual transferable quotas (ITQs) in the limited-entry groundfish trawl fishery on the U.S. Pacific coast. We use a spatial Theil index, kernel density functions of port revenue share, and Shorrocks index of intradistributional mobility to measure changes in spatial distribution. We find evidence of increased spatial concentration; however, this appears consistent with preexisting trends and not related to ITQs. Further, we find a high degree of intradistributional mobility in the revenue share of ports that coincided with ITQ implementation.

商业捕鱼登陆点的地理分布和ITQ实施后的港口整合

我们评估了在美国太平洋沿岸限制入境的底栖鱼类拖网渔业中，地理分布的变化是否与个体可转让配额(ITQs)的实施相一致。我们使用空间Theil指数、港口收入份额核密度函数和Shorrocks分配内流动性指数来衡量空间分布的变化。我们发现了空间集中度增加的证据;然而，这似乎与先前存在的趋势是一致的，与创新能力无关。此外，我们发现与ITQ实施相吻合的港口收入份额的高度分配内流动性。
