Title overview

For courses in international economics, international finance, and international trade

International Economics: Theory and Policy provides engaging, balanced coverage of the key concepts and practical applications of theory and policy around the world. Divided into two halves, with the first devoted to trade and the second to monetary questions, the text provides an intuitive introduction to theory and events as well as detailed coverage of the actual policies put into place as a response. In the 12th Edition, important economic developments are highlighted, with many lessons drawn from the recent COVID-19 pandemic experience. Using examples like these, the text equips students with the intellectual tools for understanding the changing world economy and economic implications of global interdependence.

Key features

  • The text presents a balance of theoretical and practical coverage of both trade and finance. For each topic area, chapters on core theory are followed by a series of application chapters that confront policy questions using the newest empirical work, data, and policy debates. This structure enables students to grasp theoretical concepts and then see those same concepts in action, aiding retention and highlighting the relevance of course material.
  • Sections in the text's first half provide engaging and practical coverage of the tenets and applications of international trade. Highlights include:
    • An integrated, empirical-based treatment of the latest models of trade, such as the gravity, Ricardian, factor endowments, and imperfect competition models.
    • A thorough discussion of the causes and effects of trade policy focused on the income-distribution effects of trade.
    • An emphasis on the potential substitutability of international trade and international movements of factors of production, featuring an analysis of international borrowing and lending as intertemporal trade.
  • Content in the latter half of the text brings the concepts and applications of international finance to life. Highlights include:
    • A unified model of open-economy macroeconomics that provides students with a cohesive approach to the theory, based on an asset-market approach to exchange rate determination with expectations in a central role.
    • A discussion of the international monetary experience that stresses the idea that different exchange rate systems lead to different policy coordination problems.
  • Learning Goals list essential concepts so students understand what they need to take away from each chapter.
  • Captioned Diagrams, Summaries, and Key Terms reinforce discussions and/or recap the major points in the text to aid students in their study.
  • End-of-chapter assignable problems, many of which cite real data or policies, allow students to practice what they're learning. They range from routine computational drills to more analytical questions and problems.

New to this edition

  • The following chapters provide new or updated discussion of:
    • the impacts of Brexit and COVID-19 (Chapter 7)
    • firms' global sourcing decisions and the new USMCA treaty (Chapter 8)
    • US-China trade tensions (Chapter 10)
    • the effects of the Trump trade war on global trade and the COVID-19 pandemic (Chapter 19)
    • the Dec. 2020 EU-UK trade deal plus the prior withdrawal agreement and its implications for the Irish border (Chapter 21)
    • euro area policy innovations in response to COVID-19 (Chapter 21)
  • Case Studies engage students with theory and practice, using real-world applications and events that provide important historical context. New case studies examine the potential link between import competition from developing countries and declines in manufacturing employment in the US (Chapter 4), the gains to US consumers from Chinese imports (Chapter 6), and the distributional consequences of the Trump trade war (Chapter 9).
  • Special Boxes offer vivid illustrations and videos of points made in the text, to better explain particular concepts in an engaging fashion and help students better understand key material. New boxes discuss President Trump's trade war (Chapter 4), the impact of trade shocks on developing countries (Chapter 6), currency manipulation (Chapter 19), the global financial cycle (Chapter 22), and much more.
