    Using a unique panel dataset of virtually all German academic political scientists, we show that researchers become much more productive due to the accumulation of human capital and third party funding. We also show however, that while universities of excellence have more productive researchers, individuals who go there do not become more productive. Finally, we show how women publish only 9 percent less than men with the same level of prior publication experience, but are about 26 percent less productive over their entire career, as early productivity leads to later productivity, so that women increasingly fall behind. These results cannot be explained through the influence of childbearing. Rather, they support the ‘theory of limited differences’, which argues that small differences in early productivity accumulate to large differences over entire careers, as early success encourages later success. Apart from generally showing why political scientists publish more or less, we specifically identify accumulative advantage as the principal reason why women increasingly fall behind men over the course of their careers. © 2021, The Author(s).

    We investigate the question of how long top scientists retain their stardom. We observe the research performance of all Italian professors in the sciences over three consecutive four-year periods, between 2001 and 2012. The top scientists of the first period are identified on the basis of research productivity, and their performance is then tracked through time. The analyses demonstrate that more than a third of the nation’s top scientists maintain this status over the three consecutive periods, with higher shares occurring in the life sciences and lower ones in engineering. Compared to males, females are less likely to maintain top status. There are also regional differences, among which top status is less likely to survive in southern Italy than in the north. Finally we investigate the longevity of unproductive professors, and then check whether the career progress of the top and unproductive scientists is aligned with their respective performances. The results appear to have implications for national policies on academic recruitment and advancement. © 2016, Akadémiai Kiadó, Budapest, Hungary.
