The unequal distribution of unequal pay - An empirical analysis of the gender wage gap in Switzerland

In this paper we analyze the distribution of the gender wage gap. Using microdata for Switzerland we estimate conditional wage distribution functions and find that the total wage gap and its discrimination component are not constant over the range of wages. At low wages an overproportional part of the wage gap is due to discrimination. In a further analysis of specific individuals we examine the wage gap at different quantiles and propose a new measure to assess equal earnings opportunities. These additional results reveal that it is primarily low education that causes the large discrimination component at low wages.
