Abstract:
Measures of the academic quality of individual researchers tend to ignore the context. Here we introduce contextualised measures of individual quality: cardinal and ordinal pseudo-Shapley values. The cardinal values do not add much new information if departments are roughly the same size, but the ordinal values do. Ordinal Shapley-values can be interpreted as measures of the market power of an individual, her power over the rank of her current employer, and her ability to affect rankings of all departments in a country. We use normalised Herfindahl-Hirschmann indices to assess the concentration of contributions to a department’s standing. This provides further information on the power of individuals over their departments, but also reveals the robustness of departmental rankings to job mobility.
