**Abstract**
We consider the method of moments estimation of panel dynamic simultaneous equations
models under different sample size combination of cross-sectional dimension, N; and time series
dimension, T. We consider two types of linear transformation to remove the individual-specific
effects from the model, first difference and forward demeaning. We show that the Alvarez-
Arellano type GMM estimation under both transformations is consistent only if T/N->0 as
(N,T)->inifty. However, it is asymptotically biased if T^3/N->k \neq 0. Since the validity of statistical inference depends critically on whether an estimator is asymptotically unbiased or not, we investigate the jackknife bias reduction method and derive its limiting distribution.
