No, because the sample varies slightly. But I guess I solved the problem.

Thank you all!!

Aren`t your two first stages exactly the same?

Thanks. The problem is that it only saves the first stage estimates of the
last ivreg estimation. If I do, for example, two estimates:

Ivreg y1 x1 (x2 = x3), savefprefix(first)
Ivreg y2 x1 (x2 = x3), savefprefix(first)

Estout first only list the last ones.. 

Any way to construct a table where each column is the first stage of each of
the ivreg I perform?

Is there a way of saving into a .csv file the first stage of a set of IV
regressions (for many dependent variables), either:

- In a separate table than the second stage?

OR

- In such a way that for each dependent variable there are two columns, one
for the 1st stage and other for the 2nd?


-ivreg2- on SSC can save the FSRs as sets of estimates, which can then be
combined with the 2SLS estimates using, e.g., -estout- from SSC.
