How is new economic knowledge produced over time? That depends on how the expertise of authors is managed within economic journals. Using data from 41 major economics journals spanning 21 years (1994–2014), we find that both the intensive margin (article length) and extensive margin (article number) of the discipline have been growing. In particular, the extensive margin has outgrown the intensive margin, such that each article produces absolutely more but relatively less knowledge. This pattern is highly consistent with a model of within‐journal specialization. As predicted by the model, the share of an individual article shrinks less in general interest journals and in more prestigious journals, where expertise is less substitutable across topics.

经济学生产的生产经济学

随着时间的流逝如何产生新的经济知识?这取决于如何在经济期刊中管理作者的专业知识。使用来自21年(1994-2014年)的41种主要经济学期刊的数据,我们发现该学科的集约化边际(文章长度)和广泛的边际化(文章数量)都在增长。特别是,广泛的利润率已经超过密集的利润率,因此每篇文章产生的知识绝对更多,但相对较少。这种模式与期刊内部专业化模型高度一致。正如模型所预测的那样,在一般兴趣期刊和更有名望的期刊中,单个文章的份额减少的程度较小,在这些期刊中,专业知识在各个主题之间的替代性较小。
