This paper considers the problem of testing cross-sectional correlation in large panel data models with serially …-correlated errors. It finds that existing tests for cross-sectional correlation encounter size distortions with serial correlation in … account for serial correlation of an unknown form in the error term. We derive the limiting distribution of this test as (N …

estimator, we show that when T is large, a generalized least squares estimator that ignores the correlation between the … the known correlation pattern, we derive the asymptotic properties of panel least squares estimators. Simulations are used …

In this paper, we propose a robust approach against heteroskedasticity, error serial correlation and slope … correlation and dependence of the random coefficient with covariates. The test is of great importance, since the widely used …
