st: Fixed effect vs. random effect or something else?
I am sure somebody out there will be kind enough to
provide some thoughts on the following issue.
I want to control for unobserved fixed effect along
with endogeneity in regressors for my exhaustive
unbalanced panel sample of 212 firms spanning over 8
years. Many of the explanatory variables of interests
are not that time-variant and one variable is
In this regard, my understanding is that Fixed Effect
(FE) estimation (with xtreg, fe) would control for
both unobserved and endogeneity in the regressors and
consistent and efficient for large T and if there is
sufficient within panel variation. Alternatively,
random effect (RE) estimation (xtreg, re) would only
control for random unobserved heterogeneity but not
the endogeneity issue.
Given the low within panel variation of the regressors
as well as presence of time-variant regressor, I am
not sure which way to pursue: FE or RE? I am aware
that Hausman test would provide some indication in
this regard still concern of the time-invariant nature
of my data.
Sorry if I am missing something here and any helping
hands will be highly appreciated.
