COVID-19对巴基斯坦股票市场波动性的影响
The Impact of COVID-19 on Stock Market Volatility in Pakistan
摘要:
本文通过控制汇率、利率和政府/央行干预措施的影响来研究新型冠状病毒(COVID-19)对巴基斯坦股票市场波动性(SMV)的影响。我们在2020年2月25日至2020年12月7日的样本期内使用向量自回归(VAR)模型。我们发现,对巴基斯坦每日冠状病毒病例总数的冲击导致SMV显著增加。这一结果与大量关于流行病和投资者不确定性的文献相一致,并且在我们的分析中应用了几种稳健性检查。
英文摘要:
This paper examines the impact of coronavirus (COVID-19) on stock market volatility (SMV) in Pakistan by controlling the effect of exchange rate, interest rate and government/central bank interventions to combat the pandemic. We used the vector autoregressive (VAR) model over a sample period ranging from February 25, 2020 to December 7, 2020. We find that a shock to total daily coronavirus cases in Pakistan lead to a significant increase in SMV. This result is aligned with a vast literature on pandemics and investors uncertainty and remains robust to several robustness checks applied in our analysis.
