st: Structural model with a non-linear constraints

["Blanden,J" <J.Blanden@lse.ac.uk>]

Dear statalist,

I wish to estimate the system

W=a.H +u
H=b.P + v
W=c.P + e
where c=a.b

I don't seem to be able to do this, reg3 allows only linear constraints and nl allows only single equation models.
Any help would be greatly appreciated, I'm a reduced form person in general!

Best wishes
