Economists behaving badly: publications in predatory journals

The extent of publishing in predatory journals in economics is examined. A simple model of researcher behavior is presented to explore those factors motivating an academic to publish in predatory journals as defined by Beall (Criteria for determining predatory open access publishers, Unpublished document, 3rd edn, 2015. hups://scholarlyoa.com/publishers/). Beall's lists are used to identify predatory journals included in the Research Papers in Economics archives. The affiliations of authors publishing in these outlets indicate that the geographic dispersion of authorship is widespread. A very small subset of authors is registered on RePEc. A surprising number of authors who are in the RePEc top 5% also published in predatory journals in 2015.
