The shape of economics before and after the financial crisis

This paper investigates the impact of the global financial crisis on the shape of economics as a discipline by analyzing EconLit-indexed journals from 2006 to 2020 using a multilayer network approach. We consider two types of social relationships among journals, based on shared editors (interlocking editorship) and shared authors (interlocking authorship), as well as two forms of intellectual proximity, derived from bibliographic coupling and textual similarity. These four dimensions are integrated using Similarity Network Fusion to produce a unified similarity network from which journal communities are identified. Comparing the field in 2006, 2012, and 2019 reveals a high degree of structural continuity. Our findings suggest that, despite changes in research topics after the crisis, fundamental social and intellectual relationships among journals have remained remarkably stable. Editorial networks, in particular, continue to shape hierarchies and legitimize knowledge production.
