By estimating the production frontier with the application of Data Envelopment Analysis (DEA) we rank the ‘Diamond Core’ economic journals as has been presented by Diamond (1989). By using one composite input and one composite output the paper ranks 27 core economics journals. For the first time a study attempts to rank the 27 journals by using data from SCOPUS database for the time period of 1996-2010. In addition for the first time three different quality ranking reports are incorporated in the DEA modelling problem in order to classify the journals into four categories (‘A’ to ‘D’).
