“…Notice that the limiting distribution of θ 2SIV is correctly centered, and thus no bias correction is required. As demonstrated by Cui et al (2020), the main intuition of this result lies in that F x Γ x,i is estimated from X i , whereas F y γ y,i is estimated from u i . Because V i , F y γ y,i , and ε i are independent from one another, any correlations that arise because of the estimation error of F y and F x are asymptotically negligible.…”

“…However, θ 1SIV is asymptotically biased. Rather than bias correcting this estimator, Norkute et al (2021) and Cui et al (2020) put forward a second-stage estimator, which is free from asymptotic bias and is potentially more efficient. For this purpose, the first-stage estimator is useful because it provides a consistent estimate of the error term of the model, which is required to implement the second-stage IV estimator.…”

“…The stratum phenomenon in a big data scenario can be usually elucidated so that the populations could be heterogeneous across strata due to the different dataset sources (Zhao et al, 2016). Several studies have investigated the crucial importance of stratified models and controlling latent heterogeneity with respect to the panel data models by regarding an individual as a stratum (Pesaran and Tosetti, 2011;Su and Jin, 2012;Song, 2013;Li and Lu, 2014;Chudik and Pesaran, 2015). However, the development of an alternative that only concentrates on modeling in each stratum was inadvisable because of little observations in each stratum causing "incidental parameter" issues such as panel data models (Hsiao and Pesaran, 2008;Lu et al, 2016).…”
