This multiple regression study of male and female wages in the clothing and textile industries finds that the standardized pay gap has changed against women from 1910 to 1970. The cross-section study of wages in 1909-1910 finds a very small residual in favor of men; but when the English-speaking variable is interpreted as screening many able women (but not men) from manufacturing, the residual shifts to one slightly favoring women. The cross-section study of pay in substantially the same industry group during 1969 finds very substantial residuals in favor of men after standardizing earnings. Hypotheses suggested for explaining these contrary findings include a decline in women's investment in human capital relative to that of men, and changing government and union tax and benefit patterns that discriminate against female investment in human capital.
