st: RE: Re: reg3 command and first-stage estimations

["Mentzakis, Emmanouil" <e.mentzakis@abdn.ac.uk>]

"...why in the first-stage regressions when using -reg3- command, the
instruments (capital1 and invest) are used to estimate the dependent
variable (consump)."

I think this happens because in -reg3- all dependent variables are
explicitly taken to be endogenous to the system and are treated as
correlated with the disturbances in the system's equations. So every
endogenous variable has to be instrumented. 

Check the help -reg3- file
