What is global inequality? How can it be measured? What are the major trends and patterns? What are the implications of global inequality for the world economy and multilateral governance? What role does and should inequality play in national and international policy-making? In this comprehensive overview, the authors address these key questions. They examine the major issues that need to be confronted in conceptualizing, measuring and analysing contemporary patterns of global inequality. In addition, they explore the implications of these patterns for politics and public policy. In explaining the complex global patterns of social stratification, they highlight an intensive debate about whether and to what extent inequality matters. The book also addresses this debate, and seeks to set out the major alternative positions. The book's authors include many of the most distinguished figures in the field, including David Dollar, G?sta Esping-Andersen, Nancy Fraser, James K. Galbraith, Ravi Kanbur, Branko Milanovic, Thomas W. Pogge, Bob Sutcliffe, Grahame F. Thompson, Anthony J. Venables, and Robert H. Wade. This book will be of great interest to students in politics, sociology and international relations as well as to all those interested in this key topic.
