Economic sanctions continue to play an important role in the response to terrorism, nuclear proliferation, military conflicts, and other foreign policy crises. But poor design and implementation of sanctions policies often mean that they fall short of their desired effects. This landmark study, first published in 1985, delves into the rich experience of sanctions in the 20th century to harvest lessons on how to use sanctions more effectively.This volume is the updated third edition of this widely cited study. It chronicles and examines 170 cases of economic sanctions imposed since World War I. Fifty of these cases were launched in the 1990s and are new to this edition. Special attention is paid to new developments arising from the end of the Cold War and increasing globalization of the world economy. Analyzing a range of economic and political factors that can influence the success of a sanctions episode, the authors distill a set of commandments to guide policymakers in the effective use of sanctions.
