This book collects OECD work that builds on recent contributions to the theory and empirics of comparative advantage, putting particular emphasis on the role policy can play in shaping trade.

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.

Trade flows and trade policies need to be properly quantified to describe, compare, or follow the evolution of policies between sectors or countries or over time. This is essential to ensure that policy choices are made with an appropriate knowledge of the real conditions. This practical guide introduces the main techniques of trade and trade policy data analysis. It shows how to develop the main indexes used to analyze trade flows, tariff structures, and non-tariff measures. It presents the databases needed to construct these indexes as well as the challenges faced in collecting and processing these data, such as measurement errors or aggregation bias. Written by experts with practical experience in the field, A Practical Guide to Trade Policy Analysis has been developed to contribute to enhance developing countries' capacity to analyze and implement trade policy. It offers a hands-on introduction on how to estimate the distributional effects of trade policies on welfare, in particular on inequality and poverty. The guide is aimed at government experts engaged in trade negotiations, as well as students and researchers involved in trade-related study or research. An accompanying DVD contains data sets and program command files required for the exercises. Copublished by the WTO and the United Nations Conference on Trade and Development

Centering on questions of the potential optimality of some trade protection, these original contributions present research at the frontier of international trade and trade policy. They expand and test the new trade theory that has developed during the last decade, incorporating elements of industrial organization and political economy into the study of trade structure and the formation of trade policy. Essays in the first two parts take up trade policy, addressing issues such as the formation of trading blocks, strategic trade policy, the political economy of protection, growth-oriented trade policies, and including empirical studies of the welfare effects of quality - upgrading voluntary export restrictions and import quotas. Essays in the third part discuss various structural issues such as trade in services, intersectoral adjustments, and the advantage of early entry.
