In order to use the information in the incomplete cases\, I propose an inverse probability weighted one-step imputation estimator that provides gains in efficiency relative to the complete cases estimator using a reduced form for the outcome in terms of the always-observed covariates. Unlike the two-step imputation and dummy variable methods commonly used in empirical work\, my estimator is consistent for a wide class of nonlinear models. It relies only on the commonly used "missing at random" assumption\ , and provides a specification test for the resulting restrictions. I show how the results apply to nonlinear models for fractional and nonnegative re sponses.
