Before revision:  We account for the selection bias from the  annual hours of work decision by developing and implementing an estimator for nonseparable selection models with censored selection rules. We then decompose wage changes into composition, structural and selection effects.
After revision:  We account for the selection bias from the annual hours of work and estimating a nonseparable model of wages which uses a control function to account for selection. This allows the inclusion of all individuals working positive hours and thus provides a fuller description of the wage distribution. We decompose changes in the distribution of wages into composition, structural and selection effects.
