Gender bias in academic careers: change over time?

Gender bias in science has been extensively studied, and careers are a good example. Quite some research has focused on gender differences in becoming full professor, but other aspects of the academic career are less researched, such as gender differences in leaving academia (‘the leaky pipeline’ as this is often called). Here we focus on the question whether the gender difference in leaving academia has changed over time. The findings suggest that the difference has increased at the expense of women.
