Publishing performance of Spanish academics:: 1970-2004

This work complements some of the results appearing in the article Publishing Performance in Economics: Spanish Rankings by Dolado et al. (Span Econ Rev 5:80-103, 2003) Specifically we focus on the robustness of the results regardless of the time span considered, the effect of the choice of a particular database on the final results, and the effects on changes in the unit of institutional measure (departments vs. institutions as a whole). Differences are significant when we expand the time period considered. There are also significant but small differences if we combine datasets to derive the rankings. Finally, department rankings offer a more precise picture of the situation of the Spanish academics, although results do not differ substantially from those obtained when overall institutions are considered.
