This paper scientometrically investigates concentration in economics between 1956and 2016 using a large-scale data set. It is revealed that economics is highly concentratedalong six dimensions: articles, journals, regions, institutions, authors, and paradigms. NorthAmerica accounts for half of all published articles and three quarters of all citations, while thetop twenty academic institutions reap a share of 42 percent of all citations. The top 100 authorsalone receive a share of 15 percent. Five journals account for 27.7 percent of all citations andonly 8 percent of all articles, and 3 percent of all citations may be attributed to heterodoxschools of thought. The overall Gini coefficient for the distribution of citations among articlesis 0.72. Generally, concentration is found to increase towards the top of the discipline and to behigher and more persistent on the level of citations than on the level of articles. Concentrationhas increased over the last few decades, with the strongest increases occurring already until the 1970s.
