Book excerpt: This timely new title examines the importance and impact of major international organizations and their role in global governance. International Organizations in World Politics focuses on the most influential IOs, including the United Nations, World Bank, International Monetary Fund, and World Trade Organization. For each organization, author Tamar Gutner describes their birth and evolution, governance structure, activities, and performance. A second chapter on each organization presents a case study that illuminates the constraints and challenges each IO faces. Regional organizations and issues are also examined, including the European Union and the euro crisis, as well as a case study on the African Union’s peace operations.
