Albarrán et al (2009a) introduced a novel methodology for the evaluation of citation distributions using a pair of high- and low-impact measures defined over the set of articles with citations below or above a critical citation level. Albarrán et al (2009b) presented the first empirical...

Recent results indicate that, in spite of the skewness of citation distributions, the ranking of research units that focus on the upper tail of citation distributions is quite similar to the ranking one obtains with average-based indicators. This paper explores the conjecture that this can be...

Albarrán et al. (2009a ) introduced a novel methodology for the evaluation of citation distributions consisting of a pair of high- and a low-impact measures defined over the set of articles with citations below or above a critical citation level CCL. Albarrán et al. (2009b ) presented the...

This paper contains the first empirical applications of a novel methodology for comparing the citation distributions of research units working in the same homogeneous field. The paper considers a situation in which the world citation distribution in 22 scientific fields is partitioned into three...

This paper analyzes a sample of economists from two sources: faculty members working in2007 in a selection of the 81 top Economics departments in the world, and Fellows of the Econometric Society active at that date but working elsewhere in other institutions. Productivity is measured in terms...

This paper studies evidence from Thomson Scientific about the citation process of 3.7 million articles published in the period 1998-2002 in 219 Web of Science categories, or sub-fields. Reference and citation distributions have very different characteristics across sub-fields. However, when...

This paper introduces a novel methodology for comparing the citation distributions of research units of a certain size working in the same homogeneous field. Given a critical citation level (CCL), we suggest using two real valued indicators to describe the shape of any distribution: a...

This paper contains the first empirical applications of a novel methodology for comparing the citation distributions of research units working in the same homogeneous field. The paper considers a situation in which the world citation distribution in 22 scientific fields is partitioned into three...

We use a sample consisting of economists working in 2007 in the world top 81 Economics departments, and Econometric Society Fellows working elsewhere. Productivity is based in each individual’s publications in four journal equivalent classes. We identify three elites consisting of 123, 332,...
