Dear Stat-users,
Perhaps someone can help?
I have the following problem:
I estimate two separate instrumental variable models:
Ln(CONS) = x1 + z2 (1)
Ln(EXP) = x1 + z2, (2)
z2 – is a variable to be instrumented
Now I would like to compare coefficient of z2 from the first equation to that of a second equation. Could anyone, please advise me on an appropriate test (if any) in Stata? Would suest do the job?
Thank you in advance.
