Theories of International Political Economy introduces students to the theories that make up the core, semi-periphery, and periphery of the discipline of IPE as it is studied today. Aiming to expose and clarify the differences between the orthodox and the heterodox schools of IPE, esteemed IPE scholar Stéphane Paquin expertly guides students through the fundamental principles at the heart of realist, liberal, domestic politics, Marxist, neo-Gramscian, British school, green, and feminist approaches. Engaging and accessible, this concise introduction equips students with the foundation they need to comprehend and critically assess existing IPE research and to begin forming the theoretical lens through which they will conduct their own analyses.
