The paper analyses gender wage gap in Russia using micro-data of the NOBUShousehold survey carried out by the Rosstat in 2003. The Oaxaca-Blinder decomposition of differences in average monthly wages between men and women generally confirms previous findings obtained using the RLMS data. Firstly, the asymmetric gender employment structure is the main contributor to the male-female wage gap. Secondly, both the level and the returns to accumulated human capital for women are on average higher than for men, narrowing the wage gap. Thirdly, about a half of the observed differential cannot be explained using standard decomposition framework. The unexplained gender wage differential is a proxy for an estimate of the level of discrimination and constitutes about 15–18% of the average wage of men. The implemented analysis of distribution of the unexplained gender wage gap across subgroups of workers indicates that the certain part of this gap can be explained indeed by the discrimination of women. The paper also presents an indirect evidence of «the glass ceiling» for Russian women.
