In the present text the author deals with both conventional and new approaches to trade theory and policy, treating all important research topics in international economics and clarifying their mathematical intricacies. The textbook is intended for undergraduates, graduates and researchers alike. It addresses undergraduate students with extremely clear language and illustrations, making even the most complex trade models accessible. In the appendices, graduate students and researchers will find self-contained treatments in mathematical terms. The new edition has been thoroughly revised and updated to reflect the latest research on international trade.

Krugman and Obstfeld provide a unified model of open-economy macroeconomics based upon an asset-market approach to exchange rate determination with a central role for expectations.

Global trade is of vital interest to citizens as well as policymakers, yet it is widely misunderstood. This compact exposition of the market forces underlying international commerce addresses both of these concerned groups, as well as the needs of students and scholars. Although it contains no equations, it is almost mathematical in its elegance, precision, and power of expression. Understanding Global Trade provides a thorough explanation of what shapes the international organization of production and distribution and the resulting trade flows. It reviews the evolution of knowledge in this field from Adam Smith to today as a process of theoretical modeling, accumulation of new empirical data, and then revision of analytical frameworks in response to evidence and changing circumstances. It explains the sources of comparative advantage and how they lead countries to specialize in making products which they then sell to other countries. While foreign trade contributes to the overall welfare of a nation, it also creates winners and losers, and Helpman describes mechanisms through which trade affects a country's income distribution. The book provides a clear and original account of the revolutions in trade theory of the 1980s and the most recent decade. It shows how scholars shifted the analysis of trade flows from the sectoral level to the business-firm level, to elucidate the growing roles of multinational corporations, offshoring, and outsourcing in the international division of labor. Helpman’s explanation of the latest research findings is essential for an understanding of world affairs.

"We have continued to evolve the structure and content of this textbook in step with the rapidly changing world of international business. This includes completely revising several key chapters, including Chapter 6, on International Trade. This is entirely updated and includes new case studies covering both the trade-war between the US and China and the complex Brexit process. These and other real-world developments have made a wide range of stakeholders much more aware of the significance of global trade interdependencies than in the past. Chapter 16 on the European Union is also entirely updated to take account of Brexit and a range of new socio-political and economic events in Europe. Chapter 11 ('MNEs as Responsible Stakeholders') has been removed, making this edition more consolidated,with 20 rather than 21 chapters. In place of Chapter 11 we have inserted new sections, frameworks and case studies on responsible business throughout the book as a fundamental dimension of international businesstheory and practice across all the other chapters. New case studies, such as 'Businesses and NGOs working together on climate change' in Chapter 4, provideadditional material on this topic. Chapter 14, on 'Political risk and negotiation strategy' also features new case studies on the 'US-Venezuela oil dispute' and 'Huaweiaccused of spying'"

Financial crises are traditionally analyzed as purely economic phenomena. The political economy of financial booms and busts remains both under-emphasized and limited to isolated episodes. This paper examines the political economy of financial policy during ten of the most infamous financial booms and busts since the 18th century, and presents consistent evidence of pro-cyclical regulatory policies by governments. Financial booms, and risk-taking during these episodes, were often amplified by political regulatory stimuli, credit subsidies, and an increasing light-touch approach to financial supervision. The regulatory backlash that ensues from financial crises can only be understood in the context of the deep political ramifications of these crises. Post-crisis regulations do not always survive the following boom. The interplay between politics and financial policy over these cycles deserves further attention. History suggests that politics can be the undoing of macro-prudential regulations.
