Book excerpt: Over the past few decades, corporations have been neglected in studies of international political economy (IPE). Seeking to demystify them, what they are, how they behave and their goals and constraints, this Handbook introduces the corporation as a unit of analysis for students of IPE. Providing critical discussion of their global and domestic power, and highlighting the ways in which corporations interact with each other and with their socio-political environment, this Handbook presents a thorough and up-to-date overview of the main debates around the role of corporations in the global political economy.
