Book Description
In this paper we develop a monopolistic competition model where firms exercise their market power across multiple products. Even with CES preferences, markups are endogenous. Firms choose their optimal product scope by balancing the net profits from a new variety against the costs of "cannibalizing" their own sales. With identical costs across firms, opening trade leads to fewer firms surviving in each country but more varieties produced by each of those firms. With heterogeneous costs, the number of firms surviving in equilibrium is quite insensitive to the market size. When trade is opened, more firms initially enter, but the larger market size reduces the cannibalization effect and expands the optimal scope of products. As a result, the less efficient firms exit, and the larger market is accommodated by more efficient firms that produce more varieties per firm on average.

Book Description
Product scope adjustment is a key mechanism through which multi-product firms achieve efficient resource allocations. In this paper, we take a novel perspective to study firms’ product scope adjustment behavior through the lens of asset pricing. Using a unique panel scanner data set containing detailed information on products, matched with the financial information of their manufacturers, we find that multi-product firms with higher product turnover have lower financial risks and lower risk premia. To understand this channel, we propose a stylized model with a time-dependent (Calvo-type) product turnover rate to highlight the ’risk absorption channel’ of product scope adjustment. In response to an economy-wide shock, a firm that can adjust its product scope more flexibly shows lower excess equity returns and lower asset volatility.

Book Description
Presents a new research program that is transforming the study of international trade. Until a few years ago, models of international trade did not recognize the heterogeneity of firms and exporters, and could not provide good explanations of international production networks. Now such models exist and are explored in this volume.

Book Description
What conclusions can be drawn from recent advances in international trade and international macroeconomics? New datasets, theoretical models, and empirical studies have resulted in fresh questions about the world trade and payment system. These chapters--six on trade and six on international macroeconomics--reveal the richness that researchers have uncovered in recent years. The chapters on foreign trade present, among other subjects, new integrated multisector analytical frameworks, the use of gravity equations for the estimation of trade flows, the role of domestic institutions in shaping comparative advantage, and international trade agreements. On international macroeconomics, chapters explore the relation between exchange rates and other macroeconomic variables; risk sharing, allocation of capital across countries, and current account dynamics; and sovereign debt and financial crises. By addressing new issues while enabling deeper and sharper analyses of old issues, this volume makes a significant contribution to our understanding of the global economy. Systematically illuminates and interprets recent developments in research on international trade and international macroeconomics Focuses on newly developing questions and opportunities for future research Presents multiple perspectives on ways to understand the global economy

Book Description
Product proliferation has become a common phenomenon. Most companies now offer hundreds, if not thousands, of stock keeping units (SKUs) in order to compete in the market place. Companies with expanding product and service varieties face with problems of obtaining accurate demand forecasts, controlling production and inventory costs, and providing high quality and good delivery performance for the customers. Marketing managers often advocate widening product lines for increasing revenue and market share. However, the breadth of product line can also decrease the efficiency of manufacturing processes and distribution systems. Thus firms must weigh the benefits of product variety against its cost in order to determine the optimal level of product variety to offer to their customers. Academics and practitioners are interested in several fundamental questions about product variety. For instance, why do companies extend their product lines? Do consumers care about product variety? Will a brand with more variety enjoy higher market share? How should product variety be measured? How can a company exploit its product and process design to deliver a higher level of product variety quickly and cheaply? What should the level of product variety be and what should the price of each of the product variants be? What kind of 'challenges would a company face in offering a high level of product variety and how can these obstacles be overcome? The solutions to these questions span multiple functions and disciplines.

Book Description
This book was written in honour of Professor Kalyan K. Sanyal, who was an excellent educator and renowned scholar in the field of international economics. One of his research papers co-authored with Ronald Jones, entitled “The Theory of Trade in Middle Products” and published in American Economic Review in 1982, was a seminal work in the field of international trade theory. This paper would go on to inspire many subsequent significant works by researchers across the globe on trade in intermediate goods. The larger impact of any paper, beyond the number of citations, lies in terms of the passion it sparks among younger researchers to pursue new questions. Measured by this yardstick, Sanyal’s contribution in trade theory will undoubtedly be regarded as historic. After completing his Ph.D. at the University of Rochester he joined the Department of Economics at Calcutta University in the early 1980s and taught trade theory there for almost three decades. His insights, articulation and brilliance in teaching international economics have influenced and shaped the intellectual development of many of his students. After his sudden passing in February 2012, his students and colleagues organized a symposium in his honour at the Department of Economics, Jadavpur University from April 19 to 20, 2012. This book, a small tribute to his intellect and contribution, has been a follow-up on that endeavour, and a collective effort of many people including his teachers, friends, colleagues and students. In a nutshell it discusses intermediation of various kinds with significant implications for market integration through trade and finance. That trade can generate many non-trade-service sector links has recently emerged as a topic of growing concern and can trace its lineage back to the idea of the middle product, a recurring concept in Prof. Sanyal’s work.

Book Description
Theoretical and empirical perspectives on the fragmentation of production processes across borders, shedding light on global sourcing decisions and their economic effects. Recent decades have seen a fragmentation of production processes across borders, as firms find it increasingly profitable to organize production on a global scale. This fragmentation occurs across national borders as well as across firm boundaries; companies must decide not only the location of production but also how much control to exert over the different production stages. Economists have responded to this shift by developing new models of global sourcing, generating important insights into the driving forces and economic effects of this new form of globalization. Many questions, however, remain unanswered. This book tries to fill this gap. The contributors ask new questions or offer new modeling approaches to fragmentation of production, focusing in particular on time and uncertainty. They examine global sourcing in firms' multinationalization strategies, including offshoring, product scope, managerial incentives, supplier search, and contractual issues; and explore the interactions of global sourcing, exports, and economic development, investigating such topics as the complementarity of offshoring and exporting, product diversification, and the relationship between vertical linkages and development. Each chapter presents recent research that further develops existing models or documents new empirical patterns related to global sourcing.

Book Description
Trade is a cornerstone concept in economics worldwide. This updated second edition of the essential graduate textbook in international trade brings readers to the forefront of knowledge in the field and prepares students to undertake their own research. In Advanced International Trade, Robert Feenstra integrates the most current theoretical approaches with empirical evidence, and these materials are supplemented in each chapter by theoretical and empirical exercises. Feenstra explores a wealth of material, such as the Ricardian and Heckscher-Ohlin models, extensions to many goods and factors, and the role of tariffs, quotas, and other trade policies. He examines imperfect competition, offshoring, political economy, multinationals, endogenous growth, the gravity equation, and the organization of the firm in international trade. Feenstra also includes a new chapter on monopolistic competition with heterogeneous firms, with many applications of that model. In addition to known results, the book looks at some particularly important unpublished results by various authors. Two appendices draw on index numbers and discrete choice models to describe methods applicable to research problems in international trade. Completely revised with the latest developments and brand-new materials, Advanced International Trade is a classic textbook that will be used widely by students and practitioners of economics for a long time to come. Updated second edition of the essential graduate textbook Current approaches and a new chapter on monopolistic competition with heterogeneous firms Supplementary materials in each chapter Theoretical and empirical exercises Two appendices describe methods for international trade research

Book Description
This book focuses on input trade liberalization in China and discusses the underlying causes and profound effects of Chinese enterprises facing import liberalization of intermediate input. The content of this book includes ten chapters. The analysis of this book mainly uses academic research, with policy study for a few chapters. Most chapters in this book apply the standard method of contemporary economic systems, integrating into the most advanced economic theories of international trade. The author uses theoretical models to obtain predictions which receive empirical support and carries out strict empirical research using data of China's manufacturing enterprises and China's customs to analyze the causes which affect Chinese enterprises facing import liberalization of intermediate input after China’s reform and opening-up. The suggested readership would be the public who are willing to understand the issues closely related to China’s input trade liberalization and opening-up policy, and basic knowledge in economics would be necessary in understanding the academic research part of the book. Meanwhile, this book is also specifically compelling to business persons and policy makers in that it enables deeper understanding on issues about outward foreign investment of enterprises and China’s opening-up policy and facilitates their decision-making process.
