Robustness of personal rankings: the Handelsblatt example
TL;DRAbstract
Abstract In the last years, Handelsblatt has published several rankings of business economists from German, Swiss and Austrian research institutions based on their journal publication output. These rankings have a strong influence on the academic profession. We scrutinize the Handelsblatt methodology by examining the effect the rankings’ underlying algorithms and assumptions have on the scores and ranks of individual researchers. In doing so, we clarify how robust the result is with respect to these internal parameters. Since the parameters used by Handelsblatt are not scientifically substantiated but defined ad hoc, this question is of great importance. For each parameter variation, we provide several robustness measures for both the Handelsblatt life’s work ranking and the Handelsblatt recent research performance ranking. E.g., if one applies a weighting scheme that lays more emphasis on first tier journal publications such that the weight of a particular category is always double of
