"Until the Great Recession of 2008, "global policy" on international capital flows presumed that all countries should be open to free capital flows in and out. In the wake of the crisis, even the International Monetary Fund, long a standard-bearer for free capital flows, has moderated its position. But, as Ralf Leiteritz shows in this careful study of Peru and Col ombia, what happens at the country level depends not only on what global actors think is best but also on norms, interests and institutions at the country level, as they come together to define "national identity". The book is a masterclass in empirical political economy. " Robert H. Wade,'Professor of Political Economy, London School of Economics and Political Science "Leiteritz's brilliant book convincingly connects domestic informal institutions to the international financial architecture. Demonstrating that these domestic institutions are essential for understanding the durability of national commitments to the international norm of capital mobility, Leiteritz brings a broad array of qualitative and quantitative evidence to bear on his empirical narratives. In addition to a broad-ranging analysis of systemic norms and rules, Leiteritz's book provides in-depth studies of two fascinating Latin American nations and their experiences with financial regulation. This book is an important contribution to both comparative and international political economy and should enjoy a wide audience of scholars, policy makers, and financial market participants." Rawi Abdelal, Joseph C. Wilson, Professor of Business Administration, Harvard Business School "This thoughtful and well-researched volume plugs an important whole in the understanding of capital account liberalization. The author's findings on Peru and Colombia suggest the crucial variable that explains the sustainability of openness is what he calls national economic identity. Leiteritz's examination of this key dimension of liberalization will be of interest to those who want to understand change in developing countries, the social foundations of reform, and Latin American politics."
