Hi antonio
If you specify maxldep (3) I think that stata will use yt-2 and yt-3 and yt-4
(it will never use yt-1, it is not a good instrument in the differenced
equation). Perhaps if you want to use yit-2 that menas one lag since yt-1
does not work, so you should try with maxldep(1)
Hope it works

Hi everybody
I am using xtabond to estimate a dynamic panel data model. I want to use
lagged values of Y as instruments. There is an option named maxldep(). Assume
that I want to use only y(i,t-2). If I specify maxldep(3), STATA uses yt-1
yt-2 yt-3 as instruments of Dy(i,t-1)
Any thoughts
thanks
Antonio
