Strange argues that while states remain superficially important as major actors within the global system, the underlying power relations have hollowed out their authority. This authority has in some cases flowed 'upwards' to international institutions, and in other cases flowed down to markets (and also more localised organisations). These movements have led to an asymmetry of structural authority in the global system. Strange also makes some comments regarding the state-centric nature of the discipline of International Relations and suggests a new research agenda based around her conception of structural power and the importance of non-state actors in the functioning of authority. Thus while competition between states continues in some sense, it has been joined by other fields of competition that the disciplines of International Relations and International Political Economy need to contend with if they are to remain relevant to the global political economy.
