《AJAE》|农业在经济中的重要性:从COVID-19中获知的影响



1

中文摘要:COVID-19的大部分关注都集中在对旅游业和其他服务部门的影响上:但人们对一些农业和粮食问题的兴趣日益浓厚,例如外出食品支出的下降。我们的工作考虑了FAFH在整体经济中的重要性,我们也考虑了由于COVID-19而发生的变化。我们收集有关这些组成部分的实际变化以及对非农业部门的类似冲击的数据,并采用模拟模型来估计对国内生产总值(GDP)的影响。结果表明,COVID-19对美国经济整体的影响大于COVID-19初期农业在经济中所占的份额。但是,非农业冲击仍然超过农业的影响3级。我们把结果分解为,发现FAFH支出的损失是造成农业市场冲击导致的国内生产总值变化的最大因素,并得出结论认为,在流行病期间,农业生产/贸易市场具有很强的复原力。我们的研究结果还表明,由于纳入了COVID-19的实际需求、供应和财政反应数据,我们的模型(CGE)在估计GDP与实际变化方面做得相当不错。

Abstract:Much of the attention from COVID-19 has been on the impacts on tourism and other service sectors; but there has been a growing interest in some agricultural and food topics, such as the decline in food away from home (FAFH) expenditures. Our work considers the importance of FAFH in the overall economy, and we also consider changes in agricultural production and trade that have occurred because of COVID-19. We gather data on actual changes to these components, as well as similar shocks to non-agricultural sectors, and employ a simulation model to estimate the impacts on gross domestic product (GDP). Results indicate that changes from agriculture due to COVID-19 have had a larger effect on the overall U.S. economy than the share of agriculture in the economy at the beginning of COVID-19. But the non-agricultural shocks still outweigh the impacts from agriculture by a magnitude of 3. Breaking the results down along the components, we find that the loss in FAFH expenditures is the largest contributor to the change in GDP resulting from shocks to agricultural markets and conclude that agricultural production/trade markets have been very resilient during the pandemic. Our results also indicate that our model (computable general equilibrium) does reasonably well in estimating GDP compared to actual changes due to the inclusion of data on actual demand, supply, and fiscal responses to COVID-19.
