Assessing Technical Efficiency in Commercial Fisheries: The Mid‐Atlantic Sea Scallop Fishery
利用1987-1990年中大西洋海扇贝渔船的样本数据，通过随机生产前沿分析评估技术效率，发现船主和船长仅部分补偿资源条件变化，近期法规可能短期提升整体效率。
Abstract Despite the extensive effort to research issues of allocative efficiency in fisheries, little empirical analysis of technical efficiency (TE) in fisheries exists. This study examines vessel efficiency using a stochastic production frontier based on a sample of sea scallop vessels operating in the Mid‐Atlantic between 1987 and 1990. Estimates of TE are computed and compared with input usage, resource conditions, economic performance, and recently imposed regulations. The analysis suggests that owners and captains only partially compensate for changes in resource conditions through the use of labor and fishing effort, and recent regulations may improve overall TE in the short run.
