Book excerpt: This paper proposes new GMM estimators for the panel AR(1) model when the ratio of the variance of the individual effects to the variance of the idiosyncratic errors is large. First, we present a necessary condition for large N, fixed T consistency of any Fixed Effects or Random Effects estimator for this model. This condition is also sufficient for consistency of the FE estimators, which only depend on differences of the data. Next we show that RE estimators can still be consistent when the data is mean-stationary and the ratio of the variances is infinite. For instance, when T>3, the 2-step optimal System estimator is consistent provided that the elements of the weight matrix are consistently estimated. We argue that the RE Quasi ML estimator can be used for this purpose. The commonly used 1-step and 2-step System estimators are inconsistent in this case. We also propose local asymptotic approximations to the distributions of RE GMM estimators that are more accurate than conventional approximations when the data are mean-stationary and the ratio of the variances is large and we discuss conditions for redundancy of the moment conditions that include levels of the data. Finally, we conduct a Monte Carlo study into the finite sample properties of various estimators and related confidence intervals, and to illustrate the usefulness of our new System estimator we revisit the growth study of Levine et al. (2000).
