In this paper, we propose a novel rank-based procedure to decompose ch
anges in the gender wage gap into three components: changes in the ski
ll distribution, changes in the wage structure, and improvements in th
e position of women in a ''distribution of reference.'' Using CPS data
from 1979 and 1991, we perform the decomposition at each percentile o
f the wage distribution and show that the results are sensitive to the
choice of distribution of reference (male versus overall wage distrib
ution). We also find that relative wage gains of women may have been a
source of increasing wage inequality among men.
