Dear Limdep list members:
I have a question concerning the estimator for
Two Stage Least Squares for the Fixed Effects Model.
I used this estimator to estimate a model using state fixed effects and
alternatively using regional fixed effects. My question involves the
OLS Without Group Dummy Variables.
I find that these estimates are different for my regional and state
fixed effects models even though they should be the same (a regression
with one common intercept term).
My question is why the
OLS Without Group Dummy Variables
estimates are different.
The only change I made is I sorted my data by region (the data is
originally sorted by state) in order to estimate using regional fixed
Any insights would be appreciated.
