In her classic book The Global City, Saskia Sassen tells how New York, London, and Tokyo became command centers of the global economy and, in the process, underwent massive and parallel changes. The book remakes the way we think about cities in the global economy and continues to provide lessons for the future.

Saskia Sassen is the Robert S. Lynd Professor of Sociology at Columbia University. Her books include Territory, Authority, Rights (Princeton) and A Sociology of Globalization.
