The paper examines the wage gap between women and men in the public sector during their entire careers. An analysis of cross-sectional data shows that the women-men wage ratio decreases monotonically until age 50. An analysis of panel data indicates that the gap is due largely to the fact that as a whole, men joined the public sector, mainly at advanced age, entered positions having higher wages than those of women. On-the-job-promotion during the employees' careers was a relatively minor factor. No evidence was found that men who joined public sector received a different wage premium than women, given their salary in their previous place of employment.
