-generation process, the least-squares estimators have smaller bias (in fact zero bias) but larger variances in the long regression than … in the short regression. But if the long regression is also misspecified, the bias may not be smaller. We provide bias …

This paper compares the behaviour of a bias-corrected estimator assuming strongly exogenous regressors to the behaviour … of a bias-corrected estimator assuming weakly exogenous regressors, when in fact the marginal model contains a feedback … mechanism. To this end, the effects of a feedback mechanism on the first-order least-squares coefficient estimation bias is …

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. …

of bias of (generalized) MMestimators tends to increase with the number of moment conditions exploited. Forvarious … feedbacks none of the techniques examined dominates. However, asimple bias corrected LS estimator which presupposes strict …
