Dear all,
I am currently doing an event study about COVID-19 and the differences between the G7 and BRIC. To determine possible important factors, I am considering looking at country specific characteristics (GDP per capita, Exports, country density) and COVID-19 specific data (amount of cases, health expenditures etc).
However, most of the data that is available of the country specific characteristics (like GDP per capita or amount of exports), has the same value during 3 months up to a year. I understand that I should not expect this to change daily, but is it possible to regress abnormal returns with variables that are mostly constant during these periods? Furthermore, if I choose (-3, +3), should I regress the exports and GDP per capita over the same 7 days (so that will mean I am using two constant variables) or can I regress abnormal returns with the past 2 years of GDP per capita data?
Thanks so much in advance,
