  1. The skewness of scientific productivity By Javier Ruiz-Castillo; Rodrigo Costas

  1. By: Javier Ruiz-Castillo; Rodrigo Costas
    Abstract: This paper exploits a unique 2003-2011 large dataset, indexed by Thomson & Reuters, consisting of 17.2 million disambiguated authors classified into 30 broad scientific fields, as well as the 48.2 million articles resulting from a multiplying strategy in which any article co-authored by two or more persons is wholly assigned as many times as necessary to each of them. We measure individual productivity as the number of articles per person, and as the mean citation per article per person in the same period. We focus on three types of field productivity distributions, corresponding to successful authors with an above average number of publications, as well as the population as a whole and authors with above average productivity when productivity is defined as mean citation per article per person. The main result is that, in spite of wide differences in production and citation practices across fields, field productivity distributions in these three cases share two important features: (i) they are very similar across fields, and (ii) they are highly skewed according to a robust index of skeweness, as well as the Characteristic Scores and Scales approach.
