The global financial crisis of 2008, its following bank bailouts, and associated corporate impunity sparked a renewed interest in the concept of the structural power of business and the question of “who rules?” in capitalist societies. This new wave of scholarship mitigated some of the problems of the original, theory-driven discussions from the 1970s and 1980s. But despite significant advancements in the empirical identification of business power, we lack a unified framework for studying its working mechanisms. So-called hybrid approaches, drawing on instrumental and structural power for their analyses, display high potential for such a unified and easily applicable framework. We build on this hybrid tradition and propose a novel model that integrates instrumental and structural power analysis into a basic framework. With this, we recalibrate the often rigid division between instrumental and structural power forms and emphasize the role of perceptions as key for understanding the dynamics of business power over time. We illustrate this parsimonious framework by an analysis of the plans of the Dutch government to abolish a dividend tax in 2018 that would have benefited a number of large multinationals but collapsed before implementation.
