This information comes from the most recent (1994-2014) editions of the Journal Citation Reports
, published by the Institute for Scientific Information
. Information is excerpted from the Business Finance and the Economics lists of journals. The rankings are based on "impact factor," which is the average number of citations received in 2014 by papers published in 2012 and 2013, for example. Also shown is the citation half-life, which gives the age of the article that accounted for the median citation during the year (so journals with prominent older articles have longer half-lives). Note that we have discovered some apparent errors in the calculation of the 1998 and 1999 impact factors for the JFE
and show both the original and corrected data below.
