This paper considers salary determination and the gender salary gap in the
academic labour market utilizing a particularly detailed data set of academ
ics from five old established Universities. Results reveal an aggregate gen
der salary differential for academic staff of 15%. Most of this differentia
l can, however, be explained by our model. Evidence suggests a limited oppo
rtunity for female academics to combine career and family, despite the flex
ibility of an academic job and emphasizes the importance of mobility to the
male career. Publication record is found to be an important determinant of
salary.
