Abstract:
We identify periods of mildly explosive dynamics and collapses in the stock markets of 18 major countries during the first wave of the COVID-19 pandemic of 2020. We find statistical evidence of instability transmission from the Chinese stock market to all other markets. The recovery is heterogeneous and generally non-explosive.
