<span>Using Michigan Panel
Study of Income Dynamics data, we study selection bias and the gender wage gap.
Employing several methods, we find large declines in the total and unexplained
gender gaps in wage offers between 1981 and 2015. Under our preferred selection
correction method, the median total and unexplained gaps fell by 0.378 and
0.204 log points, respectively. These are larger declines than if we had not
corrected for selection and simply measured convergence in observed wage gaps. However,
substantial selectivity-corrected median gender wage gaps remain in 2015: 0.242
log points (total gap) and 0.206 log points (unexplained gap).</span>
