Abstract

The decline of Neoclassical dominance has paved the way to a more fragmented Mainstream. In this article, we empirically explore the Mainstream’s thematic structure and its fragmentation’s effects on within-discipline communication. For this purpose, we exploit a dataset containing 10,064 articles published in economics in seven Blue Ribbon Eight journals between 1985 and 2006 and their citations. Articles are assigned to 18 topics created via Latent Dirichlet Allocation to represent specialities within economics. Results show that the economic Mainstream has yet to experience a dramatic increase in fragmentation in the observed period, and the prevailing topics are related to market equilibrium and econometrics. Moreover, the Mainstream’s thematic structure does not include any heterodox approach. Regarding communication, economists increasingly tap into diverse sources of information, and such diversity positively impacts the citational patterns of articles. The same result holds for the articles written by Nobel Prize winners and the most cited articles in the discipline, which exhibit a higher diversity than the whole sample.
经济学中主流的碎片化与传播:一个自上而下的视角
新古典主义主导地位的衰落为更加分裂的主流铺平了道路。在本文中,我们实证地探讨了主流的主题结构及其碎片化对学科内部传播的影响。为此,我们利用了一个数据集,该数据集包含1985年至2006年期间在7个Blue Ribbon Eight期刊上发表的10064篇经济学文章及其引用。文章被分配到通过潜在狄利克雷分配创建的18个主题,以代表经济学中的专业。结果表明,在观察期内,经济主流的碎片化程度尚未显著增加,主流的主题与市场均衡和计量经济学有关。此外,主流的主题结构不包括任何非正统的方法。在交流方面,经济学家越来越多地利用多样化的信息来源,这种多样性对文章的引用模式产生了积极的影响。同样的结果也适用于诺贝尔奖获得者的文章和该学科中被引用最多的文章,它们比整个样本表现出更高的多样性。
