This paper introduces a novel methodology for comparing the citation distributions of research units 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 highimpact and a low-impact...

This paper studies massive evidence about references made and citations received after a five-year citation window by 3.7 million articles published in 1998-2002 in 22 scientific fields. We find that the distributions of references made and citations received share a number of basic features...

In this paper, scientific performance is identified with the impact journal articles achieve through the citations they receive. The empirical exercise refers to 3.6 million articles published in 1998-2002 in 22 scientific fields, and the more than 47 million citations they receive in 1998-2007....

This paper presents new evidence from Spain that challenges the usual objections to the possibility of applying the rental equivalent approach to determine the weight that non-rental housing services should have in the CPI. Data from the EPFs (Encuestas de Presupuestos Familiares) for 1980-81...

This paper reviews the properties suggested in the methodological literature on the measurement of gender segregation by occupation. It is found that an index of segregation based on the entropy concept satisfies twelve basic axioms previously proposed in the single-dimensional case. This index...

Recent research has shown that two entropy-based segregation indices possess an appealing mixture of basic and subsidiary but useful properties. It would appear that the only fundamental difference between the mutual information, or M index, and the Entropy, Information or H index, is that the...

This paper defends the use of the entropy based Mutual Information index of multigroup segregation for the following five reasons. (1) It satisfies 14 basic axioms discussed in the literature when segregation takes place along a single dimension. (2) It is additively decomposable into between-...

This paper is a review of the literature on the ranking of centers of excellence in economics according to the papers published in specialized journals that have an anonymous evaluation procedure. There are two objectives: (1) to examine the evolution during the 1990’s of certain features of...

This paper reviews the properties suggested in the methodological literature on the measurement of occupational gender segregation. It is found that an index of (relative) segregation based on the entropy concept, IE, satisfies thirteen basic axioms previously proposed in the single-dimensional...

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...
