Two equations

 

Y = X + V1 + V2 + industry + time

X = Y + V1 + V2 + industry + time

 

I have an instrument, Z, that can be used to predict X.

 

I also have about 100 of industry and time dummies. (So I can't use 'model').

 

How do I go about producing the estimated coefficients for the above two equations?

 

No STATA, nor SAS seem to have the procedure for simultaneous equations.

With simultaneous equations, you need to do a little algebra first to "solve" the simultaneous equations and then fitting a model ought to be easy. And yes you can use dummy variables.

Better post it at Forecast forum since it is about SAS/ETS .

PROC MODEL can't do it ?
