Text recycling occurs more often than we expected in Dutch science. Up to one in seven papers in Dutch economics contain problematic degrees of text re-use (i.e. more than 10% of the text, with no references to the original, excluding references). Text recycling occurs more often among productive authors, papers with fewer co-authors, and in journals without clear anti-recycling guidelines.

The paper is to appear in an upcoming theme issue for Research Policy, but is available online, open access.
