| 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. |

| Abstract: | The h-index is a recent but already quite popular way of measuring research quality and quantity. However, it discounts highly-cited papers. The g-index corrects for this, but it is sensitivity to the number of never-cited papers. Besides, h- or g-index-based rankings have a large number of ties. Therefore, this paper introduces two new indices, and tests their performance for the 100 most prolific economists. A researcher has a t-number (f-number) of t (f) if t (f) is the largest number for which it holds that she has t (f) publications for which the geometric (harmonic) average number of citations is at least t (f). The new indices overcome the shortcomings of the old indices. |

| Abstract: | A rational, successive g-index is proposed, and applied to economics departments in Ireland. The successive g-index has greater discriminatory power than the successive h-index, and the rational index performs better still. The rational, successive g-index is also more robust to difference in department size. |
