摘要

临时安置补贴（TLU）通常用于在危机中支持商业渔民。我们通过随机边界分析研究了德国TLU应对配额削减和新冠肺炎大流行对渔民收入边界和效率的影响，并通过使用2008年至2020年月度登陆申报的固定效应模型研究了其对物种组成的影响。自己的上篮日增加了效率，减少了收入边界。补贴与收入边界的向外转移有关，并与不受管制的海洋物种上岸量的小幅增加有关。其他渔民的产卵期与收入边界或效率的变化无关，而是与不受管制物种的物种组成的变化有关，这些物种从淡水物种和比目鱼转向鳗鱼和其他海洋物种。随着时间的推移，技术效率大多下降，抵消了收入前沿暂时向外转移的影响。

Subsidies, Temporary Laying-Up, and Efficiency in a Coastal Commercial Fishery

Subsidies for temporary laying-up (TLU) are often introduced to support commercial fishers in crises. We studied the effect of a German TLU in response to quota cuts and the COVID-19 pandemic on fishers’ revenue frontiers and efficiency by stochastic frontier analysis, and on species composition by fixed-effects models using monthly landings declarations from 2008 to 2020. Own laying-up days increased inefficiency and decreased revenue frontiers. Subsidies were related to outward shifts in the revenue frontier, and were linked to small increases in landings of unregulated marine species. Laying-up periods by other fishers were not related to changes in the revenue frontier or efficiency, but to changes in species composition of unregulated species, away from freshwater species and flatfish, and towards eel and other marine species. Technical efficiency mostly decreased over time, offsetting temporal outward shifts in the revenue frontier.

期刊介绍： Marine Resource Economics (MRE) publishes creative and scholarly economic analyses of a range of issues related to natural resource use in the global marine environment. The scope of the journal includes conceptual and empirical investigations aimed at addressing real-world oceans and coastal policy problems. Examples include studies of fisheries, aquaculture, seafood marketing and trade, marine biodiversity, marine and coastal recreation, marine pollution, offshore oil and gas, seabed mining, renewable ocean energy sources, marine transportation, coastal land use and climate adaptation, and management of estuaries and watersheds.
