The author proposes alternative estimators that are asymptotically efficient. These methods are categorized into two-step, iterative, and continuous-updating estimators. The author then compares the finite sample properties of each, including bias, efficiency, coverage accuracy, and power. Using simulations calibrated to monthly and annual time series data, the author demonstrates that two-step and iterative estimators often suffer from severe finite sample biases and exhibit substantial size distortions in tests of overidentifying restrictions. In contrast, the continuous-updating estimator performs well, even in small samples, and often outperforms the other estimators. Notably, the continuous-updating estimator is invariant to how the moment conditions are scaled. The author's findings suggest that researchers should reconsider their traditional reliance on two-step and iterative GMM estimators in favor of continuous-updating GMM, especially when sample sizes are small or when the moment conditions are nonlinear in the parameters of interest.
