摘要

我们量化了主要金融市场受全球传染风险新闻冲击的影响程度,同时考虑了当地的疫情状况。我们为众多国家构建了一个新颖的数据集,其中包括:(i) COVID19 的相关公告;(ii) 通过 Twitter 传播的疫情新闻的高频数据(Hassan 等人,2019 年的方法论)。我们提供了有关疫情公告前后以及每日/日内频率的金融动态的新经验证据。对有关 COVID19 的传染数据和社交媒体活动的分析表明,传染风险的市场价格很高。

When the markets get CO.V.I.D: COntagion, Viruses, and Information Diffusion

We quantify the exposure of major financial markets to news shocks about global contagion risk while accounting for local epidemic conditions. For a wide cross section of countries, we construct a novel dataset comprising (i) announcements related to COVID19 and (ii) high-frequency data on epidemic news diffused through Twitter (Hassan et al., 2019’s methodology). We provide novel empirical evidence about financial dynamics both around epidemic announcements and at daily/intra-daily frequencies. Analysis of contagion data and social media activity about COVID19 suggest that the market price of contagion risk is significant.
