The paper derives a general Central Limit Theorem (CLT) and asymptotic distributions for sample moments related to panel data models with large . The results allow for the data to be cross sec...
Bias Reduction for Dynamic Nonlinear Panel Models with Fixed Effects
Fixed Eff ects Dynamic Nonlinear Panel Models
2015/9/22
The fixed effects estimator of panel models can be severely biased because of well-known incidental parameter
problems. It is shown that this bias can be reduced as T grows with n. We con...
Asymptotic Distribution of MisspeciÖed Random E§ects Estimator for a Dynamic Panel Model with Fixed E§ects When Both n and T are Large
panel model random e§ects
2015/9/22
We consider a dynamic panel AR(1) model with Öxed e§ects when both n and T are large. It is shown
that the MLE motivated by the random e§ects assumption is asymptotically unbiased even when the
...
Asymptotically Unbiased Inference for a Dynamic Panel Model with Fixed Effects When Both n and T are Large
Asymptotically Unbiased Inference Dynamic Panel Model
2015/9/22
We consider a dynamic panel AR(1) model with fixed effects when both n and T are large. Under the
“T fixed n large” asymptotic approximation, the ordinary least squares (OLS) or Gau...
