Implications of Cross-disciplinarity: Estimating the "Paper Drain" in Development Studies.

Why does the cross-disciplinary field of "development studies" have relatively low "journal impact indicators" in comparison with other mono-disciplinary fields of study? We argue that a reasonable explanation is the existence of a "paper drain" phenomenon: a certain proportion of the papers dealing with development is eventually published in journals that are assigned to other (non-development) fields. We conceptualize the paper drain phenomenon and empirically estimate its size for the field of development studies. Running an algorithmic procedure on the Scopus database, we identify six "key development issues" and estimate that the subject category of "development" is approximately publishing 28% of the papers dealings with these issues within the Social Sciences. The remaining 72% are "draining" to other (non-development) categories. We offer some recommendations in order to rise the scientific impact (and influence) of development studies, such as increasing the number of journals covered by the impact indicators.
