Objet : Re: st: control variables
Yes....(for the fixed-effects model) if the controls vary within panels
(otherwise, they will be collinear to the dummies of the fixed-effects);
if you wish to have time invariant controls along with fixed-effects, or
you wish to include the fixed-effects in the random-effects estimator
you use the "Mundlak" trick--i.e., do not include dummies for the
fixed-effects but model the cluster means (at the j level) of all
i-level variables.
See: Mundlak, Y. (1978). Pooling of Time-Series and Cross-Section Data.
Econometrica, 46(1), 69-85.
