To Pool or Not to Pool: Revisited [PDF]

open access: yesOxford Bulletin of Economics and Statistics, 2015
AbstractThis paper provides a new comparative analysis of pooled least squares and fixed effects (FE) estimators of the slope coefficients in the case of panel data models when the time dimension (T) is fixed while the cross section dimension (N) is allowed to increase without bounds.
