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.

This book emphasizes that a trading equilibrium is general rather than partial, and is often best modeled using dual or envelope functions.

World-renowned economist Ronald W. Jones gets to the essence of international trade theory in this collection of articles that span over half a century of his published work. As the global economy has grown, so too has the need for a deeper rooted understanding of trade -- and its assorted benefits. With clear, simplifying prose, Jones elucidates the Ricardian, Heckscher-Ohlin, and Specific-Factors models of general equilibrium theory. Jones' pioneering work anticipates, among other changes in our time, the creation of far-flung supply chains brought about by the falling costs of service links. The theoretical, technical, and historical insights in the text are peppered with personal notes that capture modern intellectual development in the field, providing a bedrock foundation in international trade for students and practitioners alike.

This book expounds trade theory emphasizing that a trading equilibrium is general rather than partial, and is often best modelled using dual or envelope functions. This yields a compact treatment of standard theory, clarifies some errors and confusions, and produces some new departures. In particular, the book (i) gives unified treatments of comparative statics and welfare, (ii) sheds new light on the factor-price equalization issue, (iii) treats the modern specific-factor model in parallel with the usual Heckscher-Ohlin one, (iv) analyses the balance of payments in general equilibrium with flexible and fixed prices, (v) studies imperfect competition and intra-industry trade.

The development of international trade theory has created a wide array of different theories, concepts and results. Nevertheless, trade theory has been split between partial and conflicting representations of international e- nomic interactions. Diverse trade models have co-existed but not in a structured relationship with each other. Economic students are introduced to international economic interactions with severally incompatible theories in the same course. In order to overcome incoherence among multiple theories, we need a general theoretical framework in a unified manner to draw together all of the disparate branches of trade theory into a single - ganized system of knowledge. This book provides a powerful – but easy to operate - engine of analysis that sheds light not only on trade theory per se, but on many other dim- sions that interact with trade, including inequality, saving propensities, education, research policy, and knowledge. Building and analyzing various tractable and flexible models within a compact whole, the book helps the reader to visualize economic life as an endless succession of physical ca- tal accumulation, human capital accumulation, innovation wrought by competition, monopoly and government intervention. The book starts with the traditional static trade theories. Then, it develops dynamic models with capital and knowledge under perfect competition and/or monopolistic competition. The uniqueness of the book is about modeling trade dyn- ics.

Specifically, it explores the robustness of the Heckscher - Ohlin framework and its two core propositions - the Stolper - Samuelson and Rybczynski theorems - by relaxing its underlying assumptions in four ways: limiting the inter-industry mobility of factors of production in the short run; allowing for industry economies of scale; introducing uncertainty of commodity prices; and endogenizing a country's supply of labor. Part II addresses issues related to first-best trade policies which had gained prominence during the period of multilateral trade liberalization under the auspices of the GATT, such as: the scope and limits of negotiated tariff agreements; first-best policy justifications for import restrictions and export promotions; and the use of import-quality standards as a substitute for tariffs. Part III explores the political economy of trade policy formation.

This textbook aims to explain the principles in international trade theory and show how some useful trade models work. The book concentrates on two fundamental issues in international trade, that is, the 'determinants of trade patterns' and the 'welfare gains from trade' in various economic environments. Chapters 1 through 3 assume perfect competition and explore the workings of the Ricardian model, the Heckscher-Ohlin-Samuelson model, the Specific Factors model and more recent development of the Eaton-Kortum model. Chapter 4 examines various welfare criteria and their relation to the 'social utility function' and, then, proves the basic gains-from-trade proposition. Chapters 5 and 6 examine the implications of imperfect competition using a unified oligopolistic model and variations of the monopolistically competitive model. The roles of the strategic interaction among firms, the economies of scale, product differentiation, the heterogeneity of firms, and the geographic distribution of agents will be highlighted. Chapter 7 deals with some trade policy issues such as the effects of tariffs, the relation of tariffs to other policy measures, and the so-called strategic trade policies.

International Trade: Theory, Evidence and Policy provides an integrated non-mathematical account of trade theory and policy that can be read straight through. The footnotes provide caveats, extensions and entry points, or further reading.This book is divided into three parts. The first part focuses on the core theoretical analysis of international trade that has evolved over a quarter-millennium. The second part reviews recent empirical research in global value chains, trade costs, and heterogeneous firms, particularly from analysing large datasets of individual firms' characteristics and of trade flows disaggregated to very finely detailed levels. The third section of the book analyzes trade policies and discusses current policy debates.This edition is based on Pomfret's Lecture Notes on International Trade Theory and Policy, first published in 2008. The content has been extensively updated and revised to stand as a new volume.
