This paper investigates the relationship between age and attaining a tenured position in academia (postdoctoral researcher or professorship at a university of applied sciences or university). Following considerations about ageism towards doctoral graduates who were 40 years and older (40+) upon attaining a Ph.D. and Robert K. Merton’s idea of cumulative advantages in academic careers (Matthew-Effect), we differentiate between biological and academic age. We test the relationships and the resources accumulated behind the latter using data from the DZHW Ph.D. Panel 2014. Applying piecewise constant exponential estimations and an entropy balancing methodology, we find that Ph.D.s aged 40+ experience a significantly positive effect on attaining a professorship at a university of applied science or receiving tenure as a postdoctoral researcher. We interpret the finding as a positive effect of age discrimination.
