This important new collection gathers together a world class team of contributors to assess the impact of neoliberalism on the world economy. These include Douglass C. North, Robert Keohane, Peter Hall and Peter Katzenstein. 'Roy. Denzau, and Willett have assembled a broad and distinguished group of authors who try to apply, in the real-world context of "neoliberalism," the North and Denzau "mental models" perspective. Individually, the chapters constitute illuminating case studies of not only the mental, but the political and institutional obstacles to reform. Collectively, they make a persuasive case for the importance of mental models-particularly, of our pictures about "how the world works"- in analyzing policy change.'Ronald Rogowski (Dean of the International Institute and a professor and former chair of Political Science at the University of California, Los Angeles, USA) 'Until recently, students of international political economy tended to discount the role of ideas in economic policy making. This impressive collection of essays breaks new ground in exploring how personal cognition, in the form of "shared mental models," can help shape perceptions ofinterest and policy choices. The focus is on the spread of "neo-liberal" market-oriented reforms around the globe in the 1980s and 1990s. The essays convincingly demonstrate that even when a common idea is shared, divergent social and political contexts can produce strikingly diverse outcomes. Political scientists and economists alike will learn much from the volume's insightful analysis.' Benjamin J. Cohen (Louis G. Lancaster Professor of International Political Economy, University of California, Santa Barbara, USA) '? the country and regional studies provide a very comprehensive sample of the experience with neoliberalism, and some theories on why it has had more success in some nations rather than others?By any standard, this is a very significant and ambitious book.'Michael Munger (Chairman, Department ofPolitical Science, Duke University, USA)
