This article sheds light on the political structures of forms of capitalism from a “regulationist” starting point. The parallel development of conceptualisations has limited the possibility of creating a single, unified framework, thus making it necessary to draw out the main “regulationist” assets from a critically subjective appropriation and updating. As this foundation of the regulationist method cannot claim to be exhaustive, this work attempts to find synergies with critical institutionalism based on epistemological complementarities. In an institutional and intellectual context marked by the tightening grip of neo-liberal ideas, the project consists of a work of cross-fertilization allowing the development of a broader conceptual framework articulating the “actors’ varied forms of political regulation and political work” from a constructivist perspective.
