ABSTRACT
This article investigates the recent trends in co-authorship in economics. Using data from more than 700 000 journal articles we show that the average number of authors per article has increased over the last years. This process is likely to be continued in the future. In a regression analysis, we present evidence how the authorship of papers is related to the number of citations, the JEL classification, the number of journal pages and the length of the title.
KEYWORDS:
Disclosure statement
No potential conflict of interest was reported by the authors.
Notes
1 JEL codes are not for all journals available. We excluded the Y and Z category from our analysis.
2 We skipped the legend in the figure in order to save space.
3 We also performed the logit regression of NG and obtained qualitatively the same results.
4 NG summarized the JEL categories B and N.
