In recent years, international trade has become a subject of increaed practical importance and also one of the most intellectually exciting parts of economics. In his introduction to this volume, Paul Krugman outlines why this is so, by analysing the original contribution of the New Trade Theory in interpreting and explaining the observed trade behaviour of the past twenty years. Then follow sections which discuss: formal tests of the New Trade Theory, Price Discrimination and Exchange Rate, as well as New Protectionism, measures of Comparative Advantages and Import Demand in industrialized and developing countries. Some chapters also use GCE models to evaluate Trade Protectionism, while others encompass External Trade within aggregate Disequilibrium Models.

Politics is intuitively about relationships, but until recently the network perspective has not been a dominant part of the methodological paradigm that political scientists use to study politics. This volume is a foundational statement about networks in the study of politics.

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.

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.

How do borders affect trade? Are cultural and institutional differences important for trade? Is environmental policy relevant to trade? How does one's income or wage relate to the fact that trade partners are nearby or far away? These are just some of the important questions that can be answered using the gravity model of international trade. This model predicts and explains bilateral trade flows in terms of the economic size and distance between trading partners (e.g. states, regions, countries, trading blocs). In recent years, there has been a surge of interest in this model and it is now one of the most widely applied tools in applied international economics. This book traces the history of the gravity model and takes stock of recent methodological and theoretical advances, including new approximations for multilateral trade resistance, insightful analyses of the measurement of economic distance and analyses of foreign direct investment.

This book, drawn from the Global Trade Analysis Project (GTAP), aims to help readers conduct quantitative analysis of international trade issues in an economy-wide framework. In addition to providing a succinct introduction to the GTAP modeling framework and data base, this book contains seven of the most refined GTAP applications undertaken to date, covering topics ranging from trade policy, to the global implications of environmental policies, factor accumulation and technological change.

This book was mainly written while I stayed at the Catholic University of Louvain. Professor Anton P. Barten was the one who did not only give me a warm welcome in Louvain, but also supported my research with most valuable comments and constructive criticisms. In addition I benefitted from dis cussions with Erik Schokkaert, Denis de Crombrugghe and Jo Baras on various subjects, such as the small-sample correction of Chapter 9. The arduous task of transferring my neat handwriting into a readable typescript was excellently taken care of by Brs. E. Crabbe and notably Brs. F. Duij sens, even after working hours. Mrs. A. Molders prevented me of making serious abuse of the English language. My admiration for Carien, finally, is an exponential function of the patience and enthusiasm with which she sup ported my research. Chapter I is a general introduction to the subject of linkage models, and it contains few mathematical elaborations. Chapters 2 to 4 use more, but elementary, mathematics, and treat several aspects related to the deriva tion, interpretation and estimation of linkage models. Chapter 2 deals vii tll the theory of import allocation models, Chapter J treats the problem of defining and interpreting elasticities of substitution, while Chapter 4 is concerned with the econometric problems related to the estimation of mul tivariate models with linear restrictions, such as import allocation models.
