"This is a very significant book indeed. It is as important as Castells's The Informational City."---Peter Hall, International Journal of Urban and Regional Research "[ A] high-powered and at times horrific book. [ Sassen] shows how dangerously city life has been affected by the influx of employees of the multinational firms which move into major cities, and virtually colonise them, driving even greater wedges between the rich and poor, the compulsive spending classes and low-paid part time labour attendant on their whims." * The Observer * "This is brilliant stuff, both in its broadness of sociological scope and its voluminous collection of data from a vast number of sources in the three cities."---Scott Lash, The Times Higher Education Supplement
