Book excerpt: We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the estimated model to recover unobserved qualities, marginal costs and markups. We find that variation in firm quality and product scope explains at least four fifths of the variation in firm sales. Most firms are well approximated by the monopolistic competition benchmark of constant markups, but the largest firms that account for most of aggregate sales depart substantially from this benchmark. Although the output of multiproduct firms is differentiated, cannibalization is quantitatively important for the largest firms. This imperfect substitutability of products within firms, and the fact that larger firms supply more products than smaller firms, implies that standard productivity measures are not independent of demand system assumptions and probably dramatically understate the relative productivity of the largest firms.

Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the empirical evidence on firm heterogeneity in international trade. A first wave of empirical findings from micro data on plants and firms proposed challenges for existing models of international trade and inspired the development of new theories emphasizing firm heterogeneity. Subsequent empirical research has examined additional predictions of these theories and explored other dimensions of the data not originally captured by them. These other dimensions include multi-product firms, offshoring, intra-firm trade and firm export market dynamics.

Download or read book International Trade with Heterogeneous Firms written by Alessandra Bonfiglioli and published by . This book was released on 2021 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: International trade is dominated by a small number of very large firms. Models of trade with heterogeneous firms have been developed to study the causes and consequences of this observation. The canonical model of trade with heterogeneous firms shows that trade leads to between-firm reallocations and selection: it shifts employment towards firms with the best attributes and forces marginal firms to exit. The model also illustrates the role of heterogeneity, and its various sources, in explaining the volume of trade and the firm-level margins of adjustment. Consistent with the model, earlier empirical studies have documented that exporting is a rare activity, that exporting firms are larger and more productive than other firms, and that trade liberalization reallocates market shares towards the best-performing firms in various countries. More recent studies using transaction-level data have unveiled additional salient features of trade flows. First, sales by foreign firms are very heterogeneous and highly concentrated. Second, both the extensive margin (number of exporting firms) and the intensive margin (average export per firm) are important in explaining the level of exports and its changes over time. More heterogeneity in sales across firms is associated with a higher volume of trade along both margins. Third, increased foreign competition reallocates market shares towards top firms and hence can increase concentration from any country of origin. Numerous extensions of the benchmark model have been proposed to study other important aspects, such as the relevance of multi-product and multinational firms and the extent to which heterogeneity is endogenous to firms' choices, but some open challenges still remain.
Download or read book Comparative Advantage and Heterogeneous Firms written by Andrew B. Bernard and published by . This book was released on 2006 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines how country, industry and firm characteristics interact in general equilibrium to determine nations' responses to trade liberalization. When firms possess heterogeneous productivity, countries differ in relative factor abundance and industries vary in factor intensity, falling trade costs induce reallocations of resources both within and across industries and countries. These reallocations generate substantial job turnover in all sectors, spur relatively more creative destruction in comparative advantage industries than comparative disadvantage industries, and magnify ex ante comparative advantage to create additional welfare gains from trade. The relative ascendance of high-productivity firms within industries boosts aggregate productivity and drives down consumer prices. In contrast with the neoclassical model, these price declines dampen and can even reverse the real wage losses of scarce factors as countries liberalize.

Now such models exist and are explored in this volume.
Download or read book Firm Heterogeneity and International Trade in Services written by Masayuki Morikawa and published by . This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study, using panel data on Japanese firms, analyses the relationship between services trade and firm heterogeneity. It finds that the number of firms engaged in services trade is far less than that engaged in goods trade. Further, the productivity of services traders is higher than that of domestic firms and goods trading firms, whereas the productivity of firms that export services beyond the boundary of their firm groups is higher than that of those that export services only to their affiliate firms. These results suggest that only productive firms can engage in services trade by incurring the relatively large fixed costs.
Download or read book Globalization and multiproduct firms written by Volker Nocke and published by . This book was released on 2012 with total page 30 pages. Available in PDF, EPUB and Kindle. Book excerpt: We present an international trade model with multiproduct firms. Firms are heterogeneously endowed with two types of capabilities that jointly determine the trade-off within firms between managing a large portfolio of products and producing at low marginal cost. The model can explain many of the documented cross-sectional correlations in firm performance measures, including why larger firms are more productive and more diversified, and yet more diversified firms trade at a discount. Globalization is shown to induce heterogeneous responses across firms in terms of scope and productivity, some of which are consistent with existing empirical work, while others are potentially testable.

Book excerpt: This paper reviews the new approach to international trade based on firm heterogeneity in differentiated product markets. This approach explains a variety of features exhibited in disaggregated trade data, including the higher productivity of exporters relative to non-exporters, within-industry reallocations of resources following trade liberalization, and patterns of trade participation across firms and destination markets. Accounting for these empirical patterns reveals new mechanisms through which the aggregate economy is affected by trade liberalization, including endogenous increases in average industry and firm productivity.

Available in PDF, EPUB and Kindle. Book excerpt: This thesis contributes to both theoretical and empirical aspects of the literature on firm heterogeneity in international trade. On the theoretical side, I provide insights of the consequences of trade liberalisation when firms are heterogeneous and countries are asymmetric. On the empirical side, I discuss the causality of the relationship between performances and trading status of firms. Do more productive firms self-select into international markets? Do firms become more productive because they enter international markets? These hypotheses are not mutually exclusive and my work provides support for both of them.

Available in PDF, EPUB and Kindle. Book excerpt: "This paper examines the frequency, pervasiveness and determinants of product switching among U.S. manufacturing firms. We find that two-thirds of firms alter their mix of five-digit SIC products every five years, that one-third of the increase in real U.S. manufacturing shipments between 1972 and 1997 is due to the net adding and dropping of products by survivors, and that firms are more likely to drop products which are younger and have smaller production volumes relative to other firms producing the same product. The product-switching behavior we observe is consistent with an extended model of industry dynamics emphasizing firm heterogeneity and self-selection into individual product markets. Our findings suggest that product switching contributes towards a reallocation of economic activity within firms towards more productive uses"--National Bureau of Economic Research web site

Available in PDF, EPUB and Kindle. Book excerpt: This paper reviews the recent theoretical literature on heterogeneous firms and trade, which emphasizes firm selection into international markets and reallocations of resources across firms. We discuss the empirical challenges that motivated this research and its relationship to traditional trade theories. We examine the implications of firm heterogeneity for comparative advantage, market size, aggregate trade, the welfare gains from trade, and the relationship between trade and income distribution. While a number of studies examine the endogenous response of firm productivity to trade liberalization, modeling internal firm organization and the origins of firm heterogeneity remain interesting areas of ongoing research.

This book was released on 2018-08-07 with total page 902 pages. Available in PDF, EPUB and Kindle. Book excerpt: Productivity underpins business success and national well-being and thus it is crucial to understand the factors that influence productivity growth. This volume provides a comprehensive exploration into the significance of productivity growth for business, the economy, and for social economic progress. It examines how productivity is defined, measured and implemented. It also surveys the dispersion of productivity across time and place, focusing on the productivity dynamics that either leads to a reallocation of resources that reduces dispersion and increases aggregate productivity or, conversely, allows dispersion to persist behind barriers to productivity-enhancing reallocation. A third focus is an investigation of the drivers of, or impediments to, productivity growth, some of which are organizational in nature and under management control and others of which are institutional in nature and subject to public policy intervention. The Oxford Handbook of Productivity Analysis contains contributions of distinguished productivity experts from around the world who analyze a wide range of timely issues. These issues concern purely analytical topics surrounding the measurement of productivity in various situations, beginning with the ideal situation in which all inputs and all outputs, and their prices, are observed accurately. They also include service sectors such as education in which the services provided are hard to define, much less measure, and other sectors that generate undesirable environmental externalities that are difficult to price and complicate the very definition of productivity. The issues also involve business management topics ranging from the role of business models and benchmarking to the quality of management practices, the adoption of new technologies, and possible complementarities between the two. The relationship between productivity and business performance is also explored. At a more aggregate level the issues range from the impacts of market power, incentive regulation, international trade and global value chains on productivity, to the contribution of productivity to economic development and economic welfare.
