A two-tier approach to learning makes this the most flexible book available: core theory within chapters is complemented by technical notes at the end of relevant chapters, allowing students to take their learning further. A fully up-to-date and comprehensive treatment of International Trade, this book provides a solid foundation of international trade flows and theories, as well as the latest information on empirical developments and new theoretical insights. Fundamental changes in perspectives are covered, including the role of the firm in international trade flows and organization, in terms of heterogeneity, multinational activity, and global supply chain activities. The theory is illustrated throughout with empirical evidence and an abundance of relevant case studies.

As a second tier of analysis, technical notes at the end of relevant chapters seek to support students who wish to take their learning further.
