This book represents a major contribution to our understanding of the key issues currently facing the world economy and global financial markets. It can be highly recommended as a stand-alone textbook in international finance.  It can also serve as an essential reference for both academics and practitioners interested in going beyond the standard approaches that assume market integration.  This book is unique in providing both a lucid and rigorous exposure of the complexities of risk that pervade our world, where globalization is giving way to increased nationalism and protectionism.
