用于评估渔业生产技术的渔业相关数据是由激励结构形成的，这些激励结构影响渔民在其多个生产边际中有目的的选择。使用分析和模拟相结合的方法，我们展示了市场价格和监管机构如何影响占主导地位的短期生产利润率的部署捕鱼时间在空间上。我们发现，制度驱动的空间选择导致只有部分探索的完整的生产集，产生不确定的估计生产的可能性以外的制度依赖的现状。这意味着，许多估计的渔业生产函数缺乏政策不变性，即使是最短期的政策评估任务，也可能产生误导性的预测。我们的研究结果表明，准确评估政策干预的影响，需要描述的渔业生产过程，是足够的结构，以保持不变的制度变化。JEL代码：D24、Q22。
ABSTRACT The fishery-dependent data used to estimate fishing production technologies are shaped by the incentive structures that influence fishermen's purposeful choices across their multiple margins of production. Using a combination of analytical and simulation methods, we demonstrate how market prices and regulatory institutions influence a dominant short-run margin of production—the deployment of fishing time over space. We show that institutionally driven spatial selection leads to only a partial exploration of the full production set, yielding poorly identified estimates of production possibilities outside of the institutionally dependent status quo. The implication is that many estimated fisheries production functions suffer from a lack of policy invariance and may yield misleading predictions for even the most short-run of policy evaluation tasks. Our findings suggest that accurate assessment of the impacts of a policy intervention requires a description of the fishing production process that is sufficiently structural so as to be invariant to institutional changes.
