Patterns of Research Output and Author Concentration in the Economics Literature
发现经济学文献中发表n篇论文的作者数量约为发表1篇论文作者数量的1/n^1.84，并分析了顶尖经济学期刊的作者集中度，发现三个研究生院培养了一半以上的高产作者。
This study finds that a strong bibliometric regularity exists in the publication pattern in the economics literature; the number of authors publishing n papers is approximately 1/n(superscript c) of those publishing one paper. The economics literature conforms very well to the model with c = 1.84 if data are taken from a large collection of journals. When applied to individual journals, the result shows that values of c range from 2.04 to 3.11. This paper also reports the degree of author concentration among leading economics journals. Finally, this study finds that the graduates of three graduate programs account for more than half of the top 100 authors, indicates strong institutional dominance in the production of the most prolific authors.
