Analysis of the Impact of Occupational Sex-Segregation on the Wages of Men and Women and its Significance in the Gender Pay Gap: Russian Case

This work studies the influence of horizontal occupational gender segregation on the hourly wages of men and women of Russia in the period after the crisis of 2007-2008. The percentage of women in the industry, the so-called professional feminization, is used as an indicator of occupational segregation. The analysis of the relationship includes controlling on skills and investment in human capital on different samples. The analysis of the RLMS data for 2010-2018 shows a predominantly statistically insignificant correlation between the percentage of women and hourly wages. However, for several samples the relation turned out to be positive and statistically significant. Also, as a result of applying the Oaxaca-Blinder-Newmark wage decomposition technique, the contribution of professional feminization to the gender labor gap was not found to be significant in the majority of the samples.
