However, since the number of time periods in your data is very small, you cannot rely on consistency.

You have been informed that with a lagged dependent variable as regressor, pooled OLS, FE, RE, and FD (first difference) are all inconsitent, and that you have to have recourse to dynamic panel models. I posted a link to a course which shows all this and shows (very briefly) how to use xtabond2.

Thanks Karen.
I set my basic model as follows; Y x l.y ..N= 875 and T=11 years. It s unbalanced data set. I run OLS pooled and have some normality and linearity problems. Then, I run FE and RE. FE overruled both OLS and RE. But as I included lagged dependent variable, and it is the case of large N small T, it has got some endogeneity related issues, right? Then, I tired dynamic model, namely xtabond. Then, it gave more or less the same result with FE and I think it got some autocorrelation problems etc.. So, should I go for RE? Also, if OLS has normality and linearity problems, then running FE or RE sort out that problems or not? Best Erhan
