Globalization and supply chains have re-shaped the organization of the global economy in to global production networks. The authors provide a clear framework for understanding these developments. Given the absence of a book-length treatment of GPN's by the extant literature, the value-add offered by Coe and Yeung in terms of delineating unified casual explainations for the rise and persistence of GPN's is timely and noteworthy. Across its six chapters, the book is cognizant of complementary aproaches, and seeks to inform subsequent empirical exploration by attempting conceptual development of the GPN framework. Coe and Young proceed to profile the actors involved in GPN's as well as the characteristics of these networks in Chapter 2. This is a key strength of the book, where the role of actors ex-firms such as the state, international organisations, and intermediaries are acknowledged and scrutinised for their impact on overall firm activity. Coe and Yeung have done an excellent job in illuminating a fundamental puzzle involving the evolution of production in the world economy, even as they develop a coherent theory of GPN's.
