This article argues for the utility in conceiving of two distinctive approaches to the structural power of finance—New Structural Power (NSP) and Traditional Structural Power (TSP). While both are crucial to political economy scholarship, this article highlights the intellectual trade-off that is inherent to the adoption of one perspective over the other, and it stresses the explanatory advantages of the TSP perspective specifically. First, it shows how the TSP framework can facilitate an understanding of when policymaker ideas do and do not matter in the exercise of structural power, retaining the concept of “automaticity” in structural power operations. Second, it demonstrates how each framework is custom-built to explain substantively different aspects of the policy process, with TSP research aimed at system-oriented limitation mechanisms and NSP research aimed at agent-oriented selection mechanisms. Third, it contends that TSP formulations must be embedded within a model of (contradictory) functional explanation, which is the best way to gain empirical traction on the most important macrostructural developments in contemporary finance-led capitalism. Methodologically, this implies an agenda of “explanation through commonalities” rather than the NSP-favored “explanation through variation.”
