Global Market Power
International Political Economy (IPE) scholars discussed market power in the past but not in the last couple of decades. Given the importance of both 'market' and 'power' this is a weakness that IPE should correct. This chapter reviews its past contributions as well as those of other disciplines and offers a set of concepts and theories of what market power is, what motivates which agents to use it, and how structure modifies or helps agency to exercise it. The chapter ends on the challenges to the study of market power represented by the evolving digital economy.
