Citations, journal ranking and multiple authorships: evidence based on the top 300 papers in economics

Two propositions are examined with reference to the top 300 papers in economics journals in terms of citations as reported by RePec. The results show that while there is significant correlation between the quality of a journal and the number of top papers published in that journal, the correlation is far away from being perfect. Furthermore, citations are not related to the number of authors, which provides evidence against the proposition that multi-authored papers are typically of higher quality than single-authored papers. The results also cast a shadow of doubt on the soundness of the bucket classification of journals.
