Julian,
I am also using xtabond2 and I am having problems getting the validity of
instruments accepted. I get P-value = 0, resulting from the Hansen J test. and
so far I cannot figure out why this is the case.
Could you expalin what do you mean by failing to reject the test of
over-identifying restrictions ?.
I mean do you get the validity of instruments accepted or rejected ?.
