Re: st: Fixed effects vs. Random effects
I don't think there is a minimum. Since it is a within firm (in your
case) regression, you could technically estimate a fixed effects model
with one panel, as long as there is 2 or more time observations within
Of course, you want a large number of panels for precise estimation of
the parameters, but there is any magic number on the smallest number of
panels you would need for that. The more the better. The size of your
dataset seems plenty large enough to run the model you propose.
