Postdoctoral programmes have recently become an important step leading from doctoral education to permanent academic careers in the social sciences. This paper investigates the effects of a large and structured postdoctoral programme in the social sciences on a number of academic and non-academic outcomes of fellows. Propensity score matching is employed to match fellows with applicants with similar characteristics who did not receive the fellowship; then the outcomes in the treatment and control groups are compared. The programme has a statistically significant positive effect on the general life satisfaction of former fellows and their publication activity. It is argued that an active and collegial research environment, with training in academic skills during postdoctoral employment, may improve the academic outcomes of postdoctoral fellows.
