Rise of multi-authored papers in economics: Demise of the ‘lone star’ and why?
This paper builds on previous work by reviewing the key literature relating to the rise in co-authorship in economics and by presenting further new evidence on several features of co-authorship in articles in economic journals. The empirical analysis draws on around 175,000 articles in the top 255 journals, over the period 1996–2014. The rises in quarto-plus and cross-country co-authored papers are striking, as are the differences in citations per article and citations per author. There is evidence of an alphabetical ordering of authors as the standard in co-authored papers in top journals with no downward trend evident over time. A correlation between co-authorship and career stage is observed with young authors publishing significantly more solo-authored articles.
