One more reason for academics to keep blogging….
Glenn Ellison in this paper notes the general decline in the need for academics from top institutions to publish in top journals because they can get citations [hopefully confirming that they were right] by other means – through sites like SSRN [and perhaps even by sharing their works in the blogosphere]
Over the past decade, there has been a decline in the fraction of papers in top economics journals written by economists from the highest-ranked economics departments. This paper documents this fact and uses additional data on publications and citations to assess various potential explanations. Several observations are consistent with the hypothesis that the Internet improves the ability of high-profile authors to disseminate their research without going through the traditional peer-review process.
The author further notes that:
I started this paper by pointing out two trends: economists in several highly regarded departments are publishing fewer papers in the top field journals; and Harvard’s economics department is also publishing fewer papers in the top general interest journals.
Several pieces of evidence bolster the view that one factor contributing to these trends is that the role of journals in disseminating research has been reduced. One is that the citation benefit to publishing in a top general interest journal now appears to be fairly small for top-department authors. Another is that Harvard authors appear to be quite successful in garnering citations to papers that are not published in top journals. The fact that the publication declines appear to be a top-department phenomenon (as opposed to a prolific-author phenomenon) suggests that a top-department affiliation may be an important determinant of an author’s ability to sidestep the traditional journal system.
