Product Variety and the Gains from International Trade


Book Description

An examination of the methods to measure the product variety of imports and the gains from trade due to product variety. The application of the monopolistic competition model to international trade by Elhanan Helpman, Paul Krugman, and Kelvin Lancaster was one of the great achievements of international trade theory in the 1970s and 1980s. Monopolistic competition models have required new empirical methods to implement their theoretical insights, however, and in this book Robert Feenstra describes methods that have been developed to measure the product variety of imports and the gains from trade that are due to product variety. Feenstra first considers the consumer benefits from having access to new import varieties of differentiated products, and examines a recent method to estimate the elasticity of substitution (the extent of differentiation across products) and to use that information to construct the gains from import variety. He then examines claims of producer benefit from export variety, arguing that the self-selection of the more productive firms (as the low-productivity firms exit the market) can be interpreted as a gain from product variety. He makes use of a measurement of product variety known as the extensive margin of exports and imports. Finally, he considers an alternative approach to quantifying the gains due to product variety by comparing real GDP calculated with and without the extensive margin of trade.







Product Variety Management


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.




China's Growing Role in World Trade


Book Description

In less than three decades, China has grown from playing a negligible role in international trade to being one of the world's largest exporters, a substantial importer of raw materials, intermediate outputs, and other goods, and both a recipient and source of foreign investment. Not surprisingly, China's economic dynamism has generated considerable attention and concern in the United States and beyond. While some analysts have warned of the potential pitfalls of China's rise—the loss of jobs, for example—others have highlighted the benefits of new market and investment opportunities for US firms. Bringing together an expert group of contributors, China's Growing Role in World Trade undertakes an empirical investigation of the effects of China's new status. The essays collected here provide detailed analyses of the microstructure of trade, the macroeconomic implications, sector-level issues, and foreign direct investment. This volume's careful examination of micro data in light of established economic theories clarifies a number of misconceptions, disproves some conventional wisdom, and documents data patterns that enhance our understanding of China's trade and what it may mean to the rest of the world.




Product Variety and Technical Change


Book Description

Motivated by growth models based on the variety of capital goods, recent empirical studies have established links between productivity and several trade-based measures of product variety, carrying the implication that these measures may represent technology. We study this implication by explicitly proposing the variety of capital goods available for production as a direct measure of the state of technology. Within the growth and development framework of Jones (2002, ch. 6), we derive a "conditional technological convergence" hypothesis on how this variety should behave if it were indeed to represent the state of technology. The hypothesis is tested with highly disaggregated trade data, using tools from the income convergence literature. The results suggest that a trade-based count measure of the variety of available capital goods, allowing for product differentiation by country of origin, indeed behaves "as if" it represented technology when change of technology is understood as Jones' (2002, ch. 6) learning process, and that there is conditional technological convergence among our panel of mainly OECD and transition economies.




Market Structure and Foreign Trade


Book Description

Market Structure and Foreign Trade presents a coherent theory of trade in the presence of market structures other than perfect competition. The theory it develops explains trade patterns, especially of industrial countries, and provides an integration between trade and the role of multinational enterprises. Relating current theoretical work to the main body of trade theory, Helpman and Krugman review and restate known results and also offer entirely new material on contestable markets, oligopolies, welfare, and multinational corporations, and new insights on external economies, intermediate inputs, and trade composition.




Unleashing E-Commerce for South Asian Integration


Book Description

This report is part of a broader work program on shaping a more positive narrative on regional integration in South Asia. It is a follow-up to a recent flagship report published by the South Asia Region of the World Bank, A Glass Half Full: The Promise of Regional Trade in South Asia. E-commerce is dramatically changing the way goods and services are transacted nationally, regionally, and globally. It facilitates international trade by reducing the cost of distance and remoteness and can be more inclusive of underrepresented groups such as women, small businesses, and rural entrepreneurs. Intraregional trade in South Asia is still below its potential, and the region lags behind other parts of the world in activating the potential benefits from e-commerce. Adopting a novel yet practical approach, this report explores how e-commerce can be boosted to deepen intraregional trade in South Asia. It examines the main transacting models in the digital space and the channels through which e-commerce helps reduce transactions costs for firms and consumers. It considers the regulations, as well as the regulatory gaps, affecting private sector participation in e-commerce, focusing on data privacy, consumer protection, delivery, cybersecurity, market-access regulations, and digital payments. Finally, the report presents recommendations for regulatory reforms that could enhance e-trade, especially in a regional context and as a possible platform for greater global engagement by South Asian firms. The scale of these recommendations ranges from the modest, such as allowing cross-border payments and streamlining the customs regime, to the more ambitious, such as allowing the operation of regional e-commerce platforms and liberalizing related cross-border logistics services.




A Practical Guide to Trade Policy Analysis


Book Description

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
