WebSep 1, 2024 · Introduction. This paper considers weak-identification-robust inference in a GMM framework. To conduct valid inferences without assuming model parameters are identified, Stock and Wright (2000) propose using the S statistic constructed directly from the objective function in a continuous updating GMM (henceforth, CU-GMM) framework, and … Webof weak instruments than the usual asymptotic normal distribution based on strong instruments. 4. The weak instrument asymptotic distribution of ˆδ 2SLSdepends on the nuisance parameters ρand g that cannot be consistently estimated from the data. Hence, the weak instrument asymptotic distribution is not practically useful. ρ = corr(εi,vi ...
