    Abstract: In this paper we reconsider the investigation by \cite{moosa2016} using a much larger data set of almost one million articles listed in RePEc. This article provides new insights into the effects of co-authorship on citation counts and the correlation between quality of papers and quality of the publishing journal. Our evidence is partially in contrast to the results reported in Moosa (2016). We find a positive correlation between the h-index of a journal and the quality of papers measured in terms of citations. This correlation becomes almost perfect using a non-linear model. Results from a regression of citation counts on the number of authors show evidence of a positive and significant effect of co-authorship on the quality of a paper when time effects and large sets of top-cited articles are taken into account. The inclusion of time effects and the large data set, that allows to differentiate between top-cited cohorts, add further insights to the existing literature.

  2. By: Frederick H. Wallace; Tim Perri
    Abstract: The extent of publishing in predatory journals in economics is examined in this paper. A simple model of researcher behavior is presented to explore those factors motivating an economist or other academic to publish in predatory journals as defined by Beall (2015). Beall’s lists are used to identify predatory journals and publishers included in the Research Papers in Economics archives. Once identified, the affiliations of authors publishing in these outlets are determined in order to identify the characteristics of those publishing in predatory journals. The geographic dispersion of authorship is widespread. A very small subset of authors is registered on RePEc. Around forty-five percent of registered authors who publish in predatory journals in the data set have six or fewer publications. A surprising number of authors who are in the RePEc top 5% also published in predatory journals in 2015. Key Words: Predatory Publications, RePEc
