Tóm tắt

In this paper, we investigate the gender wage differentials for Switzerland. Using micro data from the Swiss Labour Force Survey, we apply a matching method to decompose the wage gap in Switzerland. This nonparametric technique accounts for wage differences that can be due to differences in the supports. We can interpret these differences as a form of “discrimination” which is reflected in wages because women face “barriers” in accessing certain characteristics that men achieve. As a consequence, accounting for these differences in gender supports may be useful in terms of policy implications in promoting more equality between men and women.
