A critical look at the challenges facing international policy cooperation in the new postcrisis environment. The global financial crisis of 2007Â09 highlighted the economic interdependencies between all major countries, raising the issues of international cooperation. Managing Complexity looks at how, following the global financial crisis, countries have changed the way they cooperate with each other on matters of economic policy. In this volume, the result of a joint research project of Chatham House and the International Monetary Fund, researchers and policymakers who were directly involved in the crisis take a critical look at the challenges facing international policy cooperation in the new postcrisis environment and at how the theory and practice of cooperation have evolved as a result of the crisis.
