Saskia Sassen's collection is a unique contribution to the emerging literature on global cities and networks: first, because it assembles state-of-the-art presentations by leading researchers in the field, and second, because it gives due attention to key cities in the developing world, which perform vital roles in the new global networks but have hitherto been neglected. Saskia Sassen extends her path-breaking work on the first tier global cities to focus on the architecture of the networks in which they are embedded. Networking among major cities is generally taken as a key indicator of involvement in globalization, yet few studies examine what those networks actually consist of. This volume plunges into that examination, and the result is a provocative and rewarding foray into the real content of several central concepts in the contemporary discussion of globalization and urban development.... This edited volume contains United Nations U/Institute of Advanced Studies (UNU/IAS) research projects on contemporary global forces underpinnning urban development. The individual essays study the empirical and theoretical specifications on the organizational architecture of an increasing number of transnational cities, particularly cities of the global South that are mid-range on the global hierarchy.... Issues specific to Mexico, the Hormuz Corridor, Sao Paulo, Beirut, Hong Kong, Shanghai, Buenos Aires, and Amsterdam are discussed in the twelve chapters.
