The topic is interesting and timely given the current outbreak of COVID-19 in the world. The paper thus potentially adds to the literature and contributes to the understanding of the economic impacts of a major crisis or pandemic in the world.

The authors would most probably be aware that there are competing, more advanced techniques available. It would thus be helpful if these new developments are at least acknowledged in the paper. Otherwise, the chosen research methods in the paper are appropriate and acceptable.
