Importing equality?

"It is now well documented that the gender wage gap declined substantially in the 1980s, despite rising overall wage inequality. While Blau and Kahn (JoLE 1997) attribute much of this improvement to gains in women's relative labor market experience and other observable characteristics, a substantial part of the decline in the gender wage gap remains unexplained, and may be due to reduced discrimination against women in the labor market. This paper tests the hypothesis (based on Becker 1957) that increased globalization in the 1980s forced employers to reduce costly discrimination against women and thus accounted for part of the "unexplained" improvement in the gender pay gap. To test this hypothesis, we calculate change residual wage gap across industries (as well as cities) over time using CPS data from 1977-1994, and correlation between measure changes import shares. are further broken down by type of market structure an industry, i.e. whether industry is concentrated or competitive.
