WebJun 1, 2008 · Nearly-Singular design relaxes the nonsingularity assumption of the limit weight matrix in GMM, and the nonsingularity of the limit variance matrix for the first order conditions in GEL. The sample versions of these matrices are nonsingular, but in large samples we assume these sample matrices converge to a singular matrix. Webasymptotically equivalent to GMM under strong identification. More recently, in An-drews and Mikusheva (2024) shows that quasi-Bayes arises as the limit of a sequence of Bayes decision rules under weak identification. In the present paper, we show that quasi-Bayes posterior means are Lipschitz in the GMM objective function. While quasi-Bayes
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.
WebWe show that the modified K statistic is asymptotically F-distributed when the model parameters are completely unidentified or nearly-weakly identified. When the model parameters are weakly identified, the F approximation for the K statistic can be justified under the conventional asymptotics. brownie painting badge ideasWebDec 10, 2003 · This paper develops asymptotic distribution theory for GMM estimators and test statistics when some or all of the parameters are weakly identified. General results are obtained and are specialized to two important cases: linear instrumental variables regression and Euler equations estimation of the CCAPM. brownie overboard red lobsterWebasymptotically equivalent to GMM under strong identification.
