The percent female of an occupation lowers the pay it offers to both m
en and women, net of skill demands, nonpecuniary amenities and disamen
ities, and industrial and organizational characteristics. Net of these
variables, including percent female, occupations involving nurturance
offer lower wages to both men and women. We interpret these net wage
penalties for working in a more female occupation, and for doing nurtu
rant work, as sex discrimination in wage setting; occupations and type
s of skill are devalued because they are typically done by women. We s
uggest a thesis of the gendered valuation of roles and skills. The sex
gap in pay would be reduced by policies mandating comparable worth in
setting occupations' pay levels. Other factors contributing to the se
x gap in pay include men's higher representation in jobs with authorit
y and in occupations typically located in higher paying industries. So
me nonpecuniary amenities and disamenities affect pay consistent with
the theory of compensating differentials, but these make no contributi
on to the sex gap in pay.
