Thomson Reuters, in their blog Science Watch, offers a visualisation of the impact factors of journals in economics , as a result of a request made on the database JCR (Journal Citation Reports) to which the library subscribes.
The result allows us to compare the most active journals in terms of the number of publications and citations, as calculated by JCR Impact Factor and the Eigenfactor Score. This request can be replicated on the JCR database for other disciplines or to compare specific titles between them.
The library is at your disposal to help you make these requests.
The author-level Eigenfactor® score is a weighted measure of an author’s citations. It takes into account the number of authors of the paper, the number of outgoing citations from each paper citing an author’s paper, and the importance of the citing paper. All self-citations are eliminated before the score is calculated in order to remove bias, and the final score reported in the SSRN ranking tables is calculated from SSRN citation data only.
To understand how this importance-weighting works, consider the following iterated voting procedure:
“Each author begins with a single vote and passes it on, dividing the vote proportionally based on those authors whom she cites. In other words, if she cites two authors – author A one time and author B two times – she would distribute 1/3 of her vote to author A and 2/3 of her vote to author B. After one round of this procedure, some authors will receive more votes than others. In the second round, each author passes on her current vote total, as received in the previous round, again dividing this quantity equally among those authors whom she cites. This process is iterated indefinitely. Eventually, we reach a steady state in which each author receives an unchanging number of votes in each round. An author’s Eigenfactor score is the percentage of the total votes that she receives at this steady state.”

How can I access my own personal score?
Go to the “Top authors” section on SSRN and simply type your surname (here : Alemanno). As you can see, Alberto Alemanno ranks 111 within the top 30,000 authors on SSRN and his Eigenfactor Score (x100) is 0,0989 (ranks 9,062 out of 30 000).

Also, HEC Paris has moved into the top 10 rankings in the SSRN Top 1,000 International Business School, as of June 2014.
This is an outstanding achievement relating to our research publications, and will continue to raise the profile of HEC Paris worldwide.
Keep up the good work!
