Robert O. Keohane has been one of the most innovative and influential thinkers in international relations for more than three decades. His groundbreaking work in institutional theory has redefined our understanding of international political economy. This book is a selection of his most recent essays which address such core issues as interdependence, institutions, the development of international law, globalization and global governance. The essays are placed in historical and intellectual context by a substantial new introduction outlining the developments in Keohane's thought. In an original afterword, the author offers a challenging interpretation of the September 11th attacks and their aftermath. Power & Governance in a Partially Globalized World is essential reading for anyone with an interest in international relations.
