Dear,
I want to examine Bresnahan's conjecture variation. So I just try to use 3 Stage Least Square model like follows,
Q = a0 + a1 * P + a2 * Y + a3 * Z + a4 * P * Z + u
P = b0 + b1 * Q + .... - c1 * (Q/(a1 + a4 * Z)) + v
But actually, I don't know the commend for setting Q/(a1 + a4 * Z) as a variable on STATA.
How can I estimate such a model on STATA?
I will appreciate you if you let me know the commend and knowhow for this 3SLS methord
