摘要

评估COVID-19大流行的经济影响对政策制定者至关重要,但由于危机以极快的速度展开,因此具有挑战性。我们确定了三个指标-股票市场波动,基于报纸的经济不确定性,以及商业预期调查中的主观不确定性-提供了实时前瞻性不确定性措施。我们使用这些指标来记录和量化过去几周经济不确定性的大幅增加。我们还说明了如何使用这些前瞻性措施来评估2019冠状病毒病危机的宏观经济影响。具体来说,我们将新冠病毒引发的第一时刻冲击和不确定性冲击输入到Baker、Bloom和Terry(2020)开发的灾害影响估计模型中。我们的说明性计算表明,截至2020年第四季度,美国实际GDP同比收缩近11%,90%的置信区间延伸至近20%的收缩。该演习表明,约一半的预测产出收缩反映了新冠肺炎引发的不确定性的负面影响。

Covid-Induced Economic Uncertainty
Assessing the economic impact of the COVID-19 pandemic is essential for policymakers, but challenging because the crisis has unfolded with extreme speed. We identify three indicators – stock market volatility, newspaper-based economic uncertainty, and subjective uncertainty in business expectation surveys – that provide real-time forward-looking uncertainty measures. We use these indicators to document and quantify the enormous increase in economic uncertainty in the past several weeks. We also illustrate how these forward-looking measures can be used to assess the macroeconomic impact of the COVID-19 crisis. Specifically, we feed COVID-induced first-moment and uncertainty shocks into an estimated model of disaster effects developed by Baker, Bloom and Terry (2020). Our illustrative exercise implies a year-on-year contraction in U.S. real GDP of nearly 11 percent as of 2020 Q4, with a 90 percent confidence interval extending to a nearly 20 percent contraction. The exercise says that about half of the forecasted output contraction reflects a negative effect of COVID-induced uncertainty.
