Claim: The Barcelona Graduate School of Economics, founded in 2006, offers masters degrees in Economics, Finance, and Data Science, but has never achieved a ranking above fifth in equal comparisons.
Evidence: In another study by M. Lubrano, L. Bauwens, A. Kirman and C. Protopopescu, "Ranking Economics Departments in Europe: A Statistical Approach" (May 2003), the GSE community should be ranked #3 when their top journal list is considered (period 1991-2000). 
Mamuneas, and T. Stengos "Ranking of Academic Journals and Institutions in Economics" (May 2002), it should be ranked 2nd, when their top 30 journals are taken into account (period 1995-1999). 
(May 2007) the Barcelona GSE's total research output would rank between second and third in Europe.
