The main purpose of this book is to expose economics graduate students and researchers to the most significant development in international trade that has taken place in the recent past. Service transactions now make up a sizeable portion of global trade. Trade in both final and intermediate inputs is done virtually through information and communication networks, raising afresh the question of the basis of trade and calling for in-depth investigation. This book succinctly comes up with a relatively new explanation for the basis of trade, thus it adds a new dimension to three existing building blocks: technology, endowment, and returns to scale. Against a backdrop of standard Ricardian and Heckscher-Ohlin competitive models of trade, the chapters of this book nicely introduce the issue of communication cost and the difference in time zones between two trading nations. Then follow many intricate phenomena such as informality, skill formation, growth, wage inequality, and decisions regarding foreign direct investment (FDI). However, imperfectly competitive models are not dealt with in great detail as they deserve more space than can be allotted to them here. Given the nonexistence of any research-oriented in-depth analyses of competitive trade models with time-zone differences, this book is a valuable addition to the resources available to researchers and policymakers interested in deciphering recent developments in global trade patterns and the subsequent welfare effect.

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.
