As in other large recessions and depressions in times past, the global crisis of 2008-09 raised fears of worrisome prospects for international policymaking. Whether in fiscal and monetary policies, the control of currencies and capital flows, approaches to protectionism and barriers to trade, the regulation of finance, or responses to environment challenges, national economic interests were on the rise, placing at risk longstanding commitments to integration and cooperative policy. The aim of this volume is to consider the major questions that need to be faced going forwards.
