Consistent OLS estimation of AR(1) dynamic panel data models with short time series

In this article, we examine the usefulness of the bias-corrected first-difference (BCFD) estimator by Chowdhury (1987) from two angles: inference and testing. First, we compare the BCFD estimator with Bun and Carree's (2005) estimator and the GMM estimator in terms of accuracy of inference. Second, we propose to use the Hausman test based on these three estimators to test the null of no individual effects. Simulation results show that the BCFD estimator and the Hausman test based on the BCFD estimator perform better than the other two estimators.
