Hi Aga,
The user written program ivreg2 can be used to estimate this model.
'net search ivreg2' should get you on your way.

Dear Statalister,

I want to estimate a semi-log wage equation in stata by GMM. The
dependent variable is obviously log wage. I have 3 explanatory
(exogenous) variables, 3 explanatory endogenous vars and 4 instruments.
I would like also to calculate the J statistic. Any ideas how to do that
in sata?

Subject: st: Obtaining p-values for bootstrapped ols coefficients

Using the following command in Stata 8:

bs "reg y x1 x2" "_b[x1] _b[x2]", reps(10000) 

we obtain the observed coefficients, bias, se and 95% confidence
interval by
default.  Although we can change the confidence interval (e.g. to 99%),
we would
ideally like to generate p-values based on the bootstrap statistics.
anyone know if this can be done, and if so, how?

Many thanks
