The multiple faces of financialization: Financial and business services in the US economy, 1997–2020

The literature on financialization tends to overemphasize the increasing size of the financial sector vis-á-vis the rest of the non-financial business sector, usually excluding from the analysis the inter-sectoral relationships between firms. Moreover, few studies have utilized the analytical tools of network theory and the notion of centrality, despite the fact that they conceptualize financialization as the rising centrality of the financial sector. This paper attempts to address these issues and explore the evolution of financialization in the US economy before and after the subprime crisis, investigating the changes in the position of the financial sector. Informed by financial geography and the framework of Global Financial Networks (GFN), we also shed light on the impacts of financialization on those advanced business services sectors that complement financial activity, such as accounting, law, business consulting, and other business services firms. Empirically, we estimate backward and forward inter-sectoral linkages, clustering coefficients, and measures of centrality, utilizing a long time-series of input–output tables at a highly disaggregated level, in order to study the inter-sectoral evolution of financialization in the US.
