Dear All,

I have a data base with export variation (between 2020 et 2019), by origin countries, destination countries, and products.

Export variation is my dependant variable. I would like to introduce importer, exporter, and sector fixed effets in my equation.
  • First, could you tell me how to define (with xtset) my panel data in that case (I have no time dimention so I am a bit confused what are my different dimention in this panel)
  • Second, what would be the code to include these three fixed effect in my equation ?
Thanks a lot for your help !

Alexandre
