Available in PDF, EPUB and Kindle. Book excerpt: This paper sets up a model of endogenous product differentiation to analyze the variety effects of international trade. In our model multi-product firms decide not only about the number of varieties they supply but also about the degree of horizontal differentiation between these varieties. Firms can raise the degree of differentiation by investing variety-specific fixed costs. In this setting, we analyze how trade integration, i.e. an increase in market size, influences the number of firms in the market, the number of product varieties supplied by each firm, and the degree of differentiation.

Available in PDF, EPUB and Kindle. Book excerpt: This paper provides a framework to understand how market size affects firms' investments in product differentiation in a model of monopolistic competition. The theory proposes that consumers' love of variety makes them more sensitive to product differentiation efforts by firms, which leads to more differentiated products in larger markets. The framework also predicts an inverted -shaped effect of trade liberalization on product differentiation, with trade liberalization leading to more differentiated products when starting from autarky but then leading to less differentiated products as the countries approach free trade.

Available in PDF, EPUB and Kindle. Book excerpt: There are few industries in modern market economies that do not manufacture differentiated products. This book provides a systematic explanation and analysis of the widespread prevalence of this important category of products. The authors concentrate on models in which product selection is endogenous. In the first four chapters they consider models that try to predict the level of product differentiation that would emerge in situations of market equilibrium. These market equilibria with differentiated products are characterised and then compared with social welfare optima. Particular attention is paid to the distinction between horizontal and vertical differentiation as well as to the related issues of product quality and durability. This book brings together the most important theoretical contributions to these topics in a succinct and coherent manner. One of its major strengths is the way in which it carefully sets out the basic intuition behind the formal results. It will be useful to advanced undergraduate and graduate students taking courses in industrial economics and microeconomic theory.

Available in PDF, EPUB and Kindle. Book excerpt: We explore the implications of models with increasing returns, endogenous variety and firm-level heterogeneity for the quantification of the gains from trade. We first focus on the impact of trade liberalization on imported variety by analyzing the experience of Costa Rica from 1986 to 1992. We find that although liberalization triggered a sizable increase in variety, the resulting welfare gains were small because of strong heterogeneity across imported goods. Upon trade liberalization, the new varieties are imported in small quantities, and hence contribute little to welfare. We then present a model with firm-level increasing returns, differentiated goods, monopolistic competition, endogenous variety and free entry to show that total variety (domestic plus imported) can either increase, decrease or remain constant with trade liberalization. More importantly, the gains from trade do not depend on what happens to total variety. In fact, we find that, conditional on the estimated elasticities of trade with respect to trade costs, models with increasing returns, endogenous variety, free or restricted entry, and firm-level heterogeneity have exactly the same implications for welfare gains from trade liberalization as traditional models.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: This paper investigates the effect of endogenous horizontal product differentiation on trade patterns and the gains from trade under Bertrand and Cournot oligopoly. Firms differentiate their products to mitigate competition, but only if the investment required is not too high. Investment in product differentiation takes place in a much wider range of cases and results in a greater difference between products under Bertrand than Cournot competition. In our model, trade in homogeneous products never takes place under Bertrand competition: Bertrand firms export only if they differentiate their products. Cournot firms may trade in either homogeneous or differentiated products. If there is trade, consumers tend to be better off with Bertrand than Cournot competition due to greater product differentiation and more aggressive pricing, but higher levels of investment can raise Bertrand profit above Cournot profit and also above the monopoly profit at autarky when investment costs are sufficiently low.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: "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

Download or read book Market Size Trade and Productivity written by Marc J. Melitz and published by . This book was released on 2005 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: We develop a monopolistically competitive model of trade with firm heterogeneity - in terms of productivity differences - and endogenous differences in the 'toughness' of competition across markets - in terms of the number and average productivity of competing firms. We analyze how these features vary across markets of different size that are not perfectly integrated through trade; we then study the effects of different trade liberalization policies. In our model, market size and trade affect the toughness of competition, which then feeds back into the selection of heterogeneous producers and exporters in that market. Aggregate productivity and average markups thus respond to both the size of a market and the extent of its integration through trade (larger, more integrated markets exhibit higher productivity and lower markups). Our model remains highly tractable, even when extended to a general framework with multiple asymmetric countries integrated to different extents through asymmetric trade costs. We believe this provides a useful modeling framework that is particularly well suited to the analysis of trade and regional integration policy scenarios in an environment with heterogeneous firms and endogenous markups.
