SUMMARY:Research Seminar #51 : Quantifying Lifetime Productivity Changes: A Longitudinal Study of 320\,000 Late-Career Scientists
DESCRIPTION:  \nPresenter: Marek Kwiek\, University of Poznan \n  \nDiscussant: Vincent Larivière\, Université de Montréal \n  \n  \nAbstract \n\n\n\nOur focus is on persistence in research productivity over the course of an individual’s entire scientific career. We track “late-career” scientists – defined as scientists with at least 25 years of publishing experience (N=320\,564) – in 16 STEMM and social science disciplines from 38 OECD countries for up to five decades. Our OECD sample includes 79.42% of all late-career scientists research-active today. We examine the details of their mobility patterns as early-career\, mid-career\, and late-career scientists between decile-based productivity classes (from the bottom 10% to top 10% of the productivity distribution). We turn a large-scale bibliometric dataset (Scopus raw data) into a comprehensive\, longitudinal data source for research on careers in science. The global science system is highly immobile: half of global top performers continue their careers as top performers. Jumpers-Up are extremely rare in science. The chances of moving radically up (or down) in productivity classes are marginal (1% or less). Our regression analyses show that productivity classes are highly path dependent: there is a single most important predictor of being a top performer\, which is being a top performer at an earlier career stage. Methodological challenges of using structured Big Data of the bibliometric type are discussed\, with implications for global academic career studies.\n\n\n\n  \n  \nPaper: https://direct.mit.edu/qss/article/doi/10.1162/QSS.a.16/132193/Quantifying-lifetime-productivity-changes-A \n  \n  \n
