Econometric Theory (2000) WebJul 1, 2009 · In addition, we focus here on the case dubbed nearly‐weak identification where the drifting DGP introduces a limit rank deficiency reached at a rate slower than root‐T. This framework ensures the consistency of Generalized Method of Moments (GMM) estimators of all parameters, but at a rate possibly slower than usual.

WebJul 1, 2009 · Summary This paper is in the line of the recent literature on weak instruments, which, following the seminal approach of Stock and Wright captures weak identification by drifting population moment conditions. In contrast with most of the existing literature, we do not specify a priori which parameters are strongly or weakly identified. WebJul 1, 2009 · In addition, we focus here on the case dubbed nearly-weak identification where the drifting DGP introduces a limit rank deficiency reached at a rate slower than root-T.

When the model parameters are weakly identified, the F approximation for the K statistic can be justified under the conventional asymptotics.
