报告摘要：
This paper considers estimation and inferential issues of panel data models with interactive fixed effects (IFE) using diversified projections (DP) method proposed recently by Fan and Liao (2022). In contrast with ordinary least square method in Bai (2009) and weighted least square method in Bai and Li (2021), our method enjoys some merits such as robustness to the pervasive conditions on factors, stationarity condition on data, or weak serial dependence. Under certain regularity conditions, we prove that the DP estimators are root NT-consistent, and have asymptotically normal distribution. We run Monte Carlo simulations to investigate the finite sample properties of the DP estimators and find its superior performance under the setup alike to real data. We apply our method to the study on the nexus of GDP growth and financial development, and find that the estimate from the DP method is more reasonable than the alternatives in the sense that it is close to the prediction of the related economic theory.
