WebJul 19, 2005 · The purpose of this paper is to describe the performance of generalized empirical likelihood (GEL) methods for time series instrumental variable models specified by nonlinear moment restrictions as in Stock and Wright ( 2000, Econometrica 68, 1055–1096) when identification may be weak. The paper makes two main contributions. WebJan 1, 2012 · Weak identification leads to GMM statistics with nonnormal distributions, even in large samples, so that conventional IV or GMM inferences are misleading. …

It was proposed by John Denis Sargan in 1958, [1] and several variants were derived by him in 1975. [2] Lars Peter Hansen re-worked through the derivations and showed that it can be extended to general non ...
