The relative magnitudes are compared of successive terms in a higher-order asymptotic expansion of the bias of the LSDV … estimator in dynamic panels. We find that the leading term accounts for the major part of the actual bias in small samples. This … implies that bias correction procedures can be based on relatively simple bias approximation formulas. …
