Tools for Evaluating Research Output

Journal rankings are important for evaluating research output, for academic promotions, and for allocating funds. Examining the assignment of economics journals to different quartiles of citation-based rankings, the authors found that about 60% of journals remain in the same quartile and about 95% of journals remain in the same or move in a neighborhood quartile within 5- to 10-year intervals. Top journal rankings exhibit even more inertia, which is a desirable property for decisions on promotion, tenure, or institutional evaluation. A reexamination of journal assignment to different quality categories every 5 or 10 years, therefore, suffices for practical evaluation purposes.
