Dear Kevin and Statalisters:
I am glad to have a reply to my question. Thank you very much for your swift
answer.
I am actually using the -xtabond- command for my regression exercise. However,
Arellano-Bond GMM estimator is biased in the presence of unit roots and suffers
from the weak instrument problem as the coefficient of lagged dependent variable
gets close to 1, as shown in Blundell and Bond (1998, JOE) where they proposed
an alternative estimator. If there is no STATA version of Blundell-Bond
estimator procedure, I would be interested in getting GAUSS version. Please
anybody has the procedure kindly help me. Many thanks.

Please respond to
statalist
Use the -xtabond- command in versions 7 or 8. Although I think this is a useful
addition to Stata's capabilities, I personally prefer the GAUSS version of the
programme Arellano wrote because one has greater flexibility over the instrument
set used.

Dear Statalisters:
I think the same question was posted by someone else quite a while ago, but I
couldn't find the answer. I am wondering if there is anybody who has the STATA
do file to compute Blundell-Bond dynamic panel GMM estimator. If so, please let
me know. Thank you in advance for your help.
