Re: st: Clustering standard errors with Simultaneus regressions.

[John Antonakis <John.Antonakis@unil.ch>]

I have not received Stata 12; if you have it, the sem command (using the 
maximum likelihood estimator) seems to be able to handle that. Just 
model your variables as observed.

See:

http://www.stata.com/stata12/structural-equation-modeling/

Otherwise, use gllamm.  Findit -gllamm-

Best regards,
John.

P.S. your system of equations is not identified. You need to have unique 
instruments for x or y to identify the causal effects you want.
