Abstract: | We use monthly personnel records of a large German company for the years 1999–2005 to analyse the gender wage gap (GWG). The unconditional GWG is 15 per cent for blue‐collar and 26 per cent for white‐collar workers. Different returns to entry age explain a substantial part of the GWG as well as segregation of men and women in different hierarchical levels. The relative GWG increases with increasing tenure for blue‐collar but declines for white‐collar workers. Taking into account the different impact of general and firm‐specific human capital on white‐collar and blue‐collar occupation, this is consistent with theories of statistical discrimination. |
