Todayampaposs world is organized politically into nation states with sovereign national governments. But as Ralph C. Bryant explains in Turbulent Waters the worldampaposs economic structure is outgrowing its political structure. The economic links among nations have increased more rapidly than economic activity itself. As economic integration has proceeded borders have become more porous differences among national economies have eroded and the policy autonomy of national governments has been undermined. Collectivegovernance problems increasingly spill across national borders and thus grow in importance relative to problems of domestic governance. The evolving need for international cooperation and crossborder collective governance is likely to be the single most prominent feature of world politics and economics for at least the next half century. The progressive integration of the world economy often called globalization has been especially dramatic for financial activity. Crossborder financial transactions facilitate saving and investment and thereby advance the wellbeing of individuals. But they can also generate turbulence and instability. Most individuals are unsure whether financial globalization promotes or threatens prosperity for a majority of the worldampaposs people. Bryant explains basic concepts about financial activity and collective governance distills their international dimensions and enables general readers to acquire a solid grasp of the key policy issues that national governments must resolve. He provides fresh insights about what is often termed the international financial architecture. But he also casts his net far wider the bookampaposs ambitious goal is no less than to outline a pragmatically sound vision for the evolution of international governance for the world economy and financial system.
