The performance of the Newey and West (1987) heteroscedasticity and autocorrelation consistent covariance matrix for models with generated regressors is examined. The presence of a generated regressor results in the covariance matrix of the disturbance term being non-spherical, with both non-zero off-diagonal and non-constant diagonal elements. The Newey-West procedure is potentially a simple method of calculating consistent standard errors, and is available in a wide range of econometric software programs. For this reason, it would seem to be sensible to examine the small-sample performance of the Newey-West standard errors. However, the evidence from Monte Carlo experiments suggests that the Newey-West procedure performs no better than the (incorrect) two-step ordinary least squares (OLS) procedure, a finding which is supported by two illustrative empirical applications.
