Recent Trends in Co-Authorship in Economics: Evidence from RePEc

This articles 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.
