An Inverse Demand System for New England Groundfish: Welfare Analysis of the Transition to Catch Share Management
结合底层鱼类需求模型与模拟供给模型，评估美国东北部底层鱼渔业2010年从按天管理转向捕捞份额管理的福利效应，发现新政策虽比2009年差，但优于同等保护的按天管理方案。
Abstract The welfare effects of the 2010 transition from Days‐at‐Sea to catch share management in the Northeast U.S. groundfish fishery are examined by combining a model of groundfish demand with a simulation‐based model of supply. Counterfactual supply is constructed based on the Days‐at‐Sea system that was recalibrated to meet mandated conservation goals. Due to the decreases in catch that were required to meet those goals, the 2010 policy undoubtedly resulted in worse outcomes for both producers and consumers compared to 2009. However, the conservation‐equivalent Days‐at‐Sea system would have been far worse for both consumers and producers.
