Abstract This paper proposes a biased-corrected FE estimator for dynamic panel models under a large sample size. The proposed bias-corrected estimator has several advantages compared to other dynamic panel estimators: first of all, it works for panel autoregressive coefficient in (-1,1]. Secondly, it is more efficient than the bias-corrected first-difference estimator. Lastly, unlike most existing dynamic panel estimators, the consistency of the proposed bias-corrected estimator does not depend on the stationarity of the initial condition. This paper further extends the model to include exogenous variables and heteroskedasticity. Based on the asymptotic distributions of the FE estimator under large n and T, the bias-corrected estimators for the models with exogenous variables and heteroskedasticity are proposed. According to the Monte Carlo simulations, the proposed bias-corrected estimator outperforms the GMM-type estimators in a large sample size.
