The COVID-19 pandemic has caused escalating levels of business, economic and societal uncertainty and created extensive disruptions around the world. Policymakers have responded with a variety of measures to combat this unprecedented crisis. This paper investigates the stock market reactions to the national policy responses. We focus on the two influential policy actions: the nationwide lockdown order aiming to slow down the spread of the Coronavirus, and the interest rate cut policy aiming to minimize the negative economic impact of the pandemic. The Difference-In-Difference method is employed to conduct a cross-country analysis. We find that both policy actions have a significant and positive impact on the stock market performance. We also document a larger stock market reaction to the announcement of an interest rate cut policy than that of a lockdown order.
新冠疫情导致商业、经济和社会的不确定性不断升级,并在全球造成了广泛的破坏。政策制定者已采取各种措施来应对这一前所未有的危机。本文研究了股票市场对国家政策应对措施的反应。我们关注两项有影响力的政策行动:旨在减缓新冠病毒传播的全国性封锁令,以及旨在将疫情对经济的负面影响降至最低的降息政策。我们采用双重差分法进行跨国分析。我们发现,这两项政策行动都对股票市场表现产生了重大的积极影响。我们还记录到,股票市场对降息政策公告的反应比对封锁令公告的反应更大。
