| Abstract: |
We explore the relationship between collaborations in writing papers and the
academic productivity of economists and, particularly, we describe the
magnitude and intensity of co-authorship among economists. To that end, we
employ interaction maps from Complex Systems methods to study the global
properties of specific networks. We use 8,253 JCR papers from ISI-WOK,
published by 5,188 economists from Spanish institutions, and their co-authors,
up to 8,202 researchers, from 2002 to 2014, to identify and determine the
collaborative structure of economics research in Spain, with its primary
communities and figures of influence. Our results indicate that centrality and
productivity are correlated, particularly with respect to a local estimator of
centrality (page rank), and we provide certain recommendations, such as
promoting interactions among highly productive authors who have few co-authors
with other researchers in their environment, or recommending that authors who
may be well-positioned but minimally productive strive to improve their
productivity. |
