In “Theorizing European Integration: The Case for a Transnational Critical Approach,” Apeldoorn, Overbeek, and Ryner argue that orthodox approaches to European regional integration, such as realism, liberalism, constructivism, and traditional Marxism, overlook the diffused power of elite consensus. They believe Neo-Gramscian approaches can reveal the agency of elite interests, and their formation of a neo-liberal hegemonic bloc supporting integration schemes. Stephen Gill has applied this perspective to explain regional integration schemes with the theoretical framework of New Constitutionalism. Yet other Neo-Gramscians contend that New Constitutionalism is pessimistically determinist, focusing solely on the agency of a liberal elite while overlooking the agency displayed by progressive social forces in formulating regional integration policy.
