Dear Statalist,
I am estimating the following 2SLS model:
Firm Performance = A B (C = E F Firm Performance)
I noticed that whereas ivreg allows to use the SAME variable as
overall depdndent varialble AND instrument, ivreg2 does not allow to
do so.
Personally, I consider it as awkward to somehow predict a variasble by
itself, even on a 2sls, however I am wondering what is actually
correct?
Best
Chris
