I can estimate each equations separately using nl. However, when I try

to estimate the system using the same syntax as linear estimation for a

system of equations, I get a varlist error. What is the syntax or how

do you estimate a non-linear system of eqation in Stata 9.0?

You don't. You might find that the Stata 10 command -nlsur- will do the job.

In Stata 9.x, you could use -ml- if you are willing to make distributional assumptions. That is, you would have to write down the likelihood function of the system. See any econometrics textbook re FIML.
