A simple consistent GMM estimation method is proposed that avoids the weak moment condition problem that is known to affect conventional GMM estimation when the autoregressive coefficient (\n                    <jats:italic>\u03c1<\/jats:italic>\n                    ) is near unity. In both panel and time series cases, the estimator has standard Gaussian asymptotics for all values of\n                    <jats:italic>\u03c1<\/jats:italic>\n                    \u2208 (\u22121, 1] irrespective of how the composite cross-section and time series sample sizes pass to infinity.
