I would like to analyze the future effect of Covid 19 pandemics on the Gini index (income inequality).
Which dependent variables should I use in order to see the effect of the pandemics?
For example, I think that I should use oil prices in order to include time fixed effects. But, which variables I should include? (Note that the variables should be accessible publicly, for example, from world bank data... etc.)
What are your opinions? Thank you.
