We consider censored structural latent variables modelswhere some exogenous variables are subject toadditive measurement errors. We demonstrate thatoveridentification conditions can be exploited toprovide natural instruments for the variablesmeasured with errors, and we propose a two-stageestimation procedure. The first stage involvessubstituting available instruments in lieu of thevariables that are measured with errors andestimating the resulting reduced form parametersusing consistent censored regression methods. Thesecond stage obtains structural form parametersusing the conventional linear simultaneous equationsmodel estimators.
