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.

The monopolistic competition model in international trade offers three sources of gains from trade that do not arise in competitive models: expansion in product variety; a pro-competitive reduction in the markups charged by firms; and the self-selection of more efficient firms into exporting. Recent literature on trade with heterogeneous firms has emphasized the third of these effects, and the first two effects are ruled out when using a Pareto distribution for productivity with a support that is unbounded above. The goal of this paper is to restore a role for product variety and pro-competitive gains from trade by using a bounded Pareto distribution for productivity.

"Since the seminal work of Krugman (1979), product variety has played a central role in models of trade and growth. In spite of the general use of love-of-variety models, there has been no systematic study of how the import of new varieties has contributed to national welfare gains in the United States. In this paper we show that the unmeasured growth in product variety from US imports has been an important source of gains from trade over the last three decades (1972-2001). Using extremely disaggregated data, we show that the number of imported product varieties has increased by a factor of four. We also estimate the elasticities of substitution for each available category at the same level of aggregation, and describe their behavior across time and SITC-5 industries. Using these estimates we develop an exact price index and find that the upward bias in the conventional import price index is approximately 1.2 percent per year. The magnitude of this bias suggests that the welfare gains from variety growth in imports alone are 2.8 percent of GDP"--NBER website

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
