Productivity Measurement in Common Property Resource Industries: An Application to the Pacific Coast Trawl Fishery
测量了公共资源产业的全要素生产率，重点关注资源估值、可捕性和产能利用率，以太平洋海岸拖网渔业为例，发现剔除资源丰度变化后平均生产率增长降低约一半，有助于可持续资源管理。
This article measures total factor productivity in industries that exploit resources held in common. Particular attention is paid to the valuation and specification of in situ commonproperty resources in a neoclassical production technology, catchability of the resource, and variations in economic capacity utilization. An empirical analysis of the open-access Pacific coast trawl fishing industry demonstrates that disentangling the productivity residual from changes in resource abundance, its catchability, and variations in capacity utilization hones the productivity residual to finer precision, lowering mean productivity growth by about haK Removing biological noise from highly variable resources is also important. The results are related to aprogram limiting the number of vessels and can contribute to sustainable resource management whenever resources are held in common.
