Abstract

We develop a theoretical trade model based on classical welfare economics and apply it empirically to both importers and exporters of shrimp, the most traded seafood, to determine the effects of the Covid-19 pandemic on shrimp produced and consumed in the U.S. and globally. We consider two time periods and compare these to the base period before the pandemic. Period 1 (March–June 2020): there is a net economic loss globally of $194 million due to lockdowns. Period 2 (July 2020–June 2021): there is a net welfare gain globally of $885 million due to increased shrimp demand. Overall, the global net economic gain was $692 million. For the United States alone, shrimp consumers gained $470 million while shrimp producers gained $24 million, which is relatively consistent with the net quasi-consumer gain of $475 million due to the Covid-19 pandemic.

海鲜供需中断:Covid-19 大流行和虾

摘要

我们开发了一个基于经典福利经济学的理论贸易模型,并将其经验性地应用于贸易量最大的海产品虾的进口商和出口商,以确定 Covid-19 大流行对美国和全球生产和消费的虾的影响。我们考虑两个时间段,并将它们与大流行之前的基期进行比较。第一阶段(2020 年 3 月至 6 月):由于封锁,全球经济净损失为 1.94 亿美元。第 2 期(2020 年 7 月至 2021 年 6 月):由于对虾需求的增加,全球福利净收益为 8.85 亿美元。总体而言,全球净经济收益为 6.92 亿美元。仅就美国而言,虾类消费者获得了 4.7 亿美元,而虾类生产者获得了 2400 万美元,这与 Covid-19 大流行导致的准消费者净收益 4.75 亿美元相对一致。
