Figure 3
The image contains two vertical bar graphs side by side. The left graph, titled 'Most Relevant Authors,' displays the number of articles published by various authors. The horizontal axis represents the number of articles, while the vertical axis lists the authors' names. The right graph, titled 'Most Relevant Sources,' shows the number of articles published in different journals. The horizontal axis represents the number of articles, and the vertical axis lists the journal names. Both graphs indicate a concentration of publications among a few authors and journals, with 'The World Economy' having the highest number of articles. The graphs suggest a moderately concentrated and diversified journal market and a limited number of scholars with high publication rates.Most relevant authors and sources
