How to Count Citations If You Must: Comment

David Stern () and Richard Tol ()

Working Paper Series from Department of Economics, University of Sussex

Abstract: Perry and Reny (2016) show that the Euclidean length of a citation list satisfies five axioms including "depth relevance". We explore "breadth relevance", which favors consistent achievers over one-hit wonders. A convex combination of depth and breadth relevant citation metrics does not satisfy the independence axiom, but violations are rare. We estimate the parameters of this metric using two datasets and three rankings, controlling for cohort effects. We find that simply counting citations--neither breadth nor depth--maximizes the correlation between citation index and department rank. However, depth may explain the allocation of researchers across lower ranked departments.
