A balanced, global approach to economic theory and policy applications

International Economics: Theory and Policy provides balanced coverage of key concepts and practical applications of theory and policy around the world. With the first half devoted to trade and the second to monetary questions, the text provides an intuitive intro to theory and events as well as detailed coverage of the actual policies put into place as a response.

Drawing lessons from the COVID-19 pandemic, the 12th Edition highlights important economic developments, so students understand the changing world economy and economic implications of global interdependence.

Hallmark features of this title

A unified structure

  • For each topic, chapters on core theory are followed by application chapters that confront policy questions using the newest work, data and policy debates, so students see concepts in action.
  • The first half of the text provides engaging and practical coverage of the tenets and applications of international trade. Content in the latter brings international finance to life.

Learner-focused tools

  • Learning Goals list essential concepts so students understand the takeaway from each chapter.
  • Captioned Diagrams, Summaries, and Key Terms reinforce discussions and/or recap the major points in the text to aid students' study.
  • End-of-Chapter Problems, many of which cite real data or policies, allow students to practice what they're learning.

New and updated features of this title

The latest events

  • NEW and UPDATED: Discussions highlight recent developments in international economics theory and policy. They include the impacts of Brexit and COVID-19 (Ch. 7), firms' global sourcing decisions and the new USMCA treaty (Ch. 8), US-China trade tensions (Ch. 10), and the effects of the Trump trade war on global trade and the COVID-19 pandemic (Ch. 19).

Learner-focused tools

  • NEW and UPDATED: Case Studies engage students with theory and practice, using real-world applications and events that provide important historical context. New cases examine the potential link between import competition from developing countries and declines in manufacturing employment in the US (Ch. 4), the gains to US consumers from Chinese imports (Ch. 6), and the distributional consequences of the Trump trade war (Ch. 9).
  • UPDATED: Special Boxes offer vivid illustrations and videos of points made in the text, to better explain particular concepts in an engaging fashion. New boxes discuss the impact of trade shocks on developing countries (Ch. 6), currency manipulation (Ch. 19), the global financial cycle (Ch. 22), and more.
