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.

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.

This book was released on 2015 with total page 577 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbook of the Political Economy of International Trade surveys the literature on the politics of international trade and highlights the most exciting recent scholarly developments. The Handbook is focused on work by political scientists that draws extensively on work in economics, but is distinctive in its applications and attention to political features; that is, it takes politics seriously. The Handbook's framework is organized in part along the traditional lines of domestic society-domestic institutions - international interaction, but elaborates this basic framework to showcase the most important new developments in our understanding of the political economy of trade. Within the field of international political economy, international trade has long been and continues to be one of the most vibrant areas of study. Drawing on models of economic interests and integrating them with political models of institutions and society, political scientists have made great strides in understanding the sources of trade policy preferences and outcomes. The 27 chapters in the Handbook include contributions from prominent scholars around the globe, and from multiple theoretical and methodological traditions. The Handbook considers the development of concepts and policies about international trade; the influence of individuals, firms, and societies; the role of domestic and international institutions; and the interaction of trade and other issues, such as monetary policy, environmental challenges, and human rights. Showcasing both established theories and findings and cutting-edge new research, the Handbook is a valuable reference for scholars of political economy.

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.

Book excerpt: This paper sets out a basic heterogeneous-firms trade model that is closely akin to Melitz (2003). The positive and normative properties of the model are studied in a manner intended to highlight the core economic logic of the model. The paper also studies the impact of greater openness at the firm-level and aggregate level, focusing on changes in the number and type of firms, trade volumes and prices, and productivity effects. The normative effects of liberalisation are also studied and here the paper focuses on aggregate gains from trade, and income redistribution effects, showing inter alia that the model is marked by a Stolper-Samuelson like effect. A number of empirically testable hypotheses are also developed. These concern the impact of greater openness on the firm-level trade pattern, the variance of unit-prices, the stock market valuation of firms according to size, and the lobbying behaviour by size.

Download or read book Falling Trade Costs Heterogeneous Firms and Industry Dynamics written by Andrew B. Bernard and published by . This book was released on 2003 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper examines the response of industries and firms to changes in trade costs. Several new firm-level models of international trade with heterogeneous firms predict that industry productivity will rise as trade costs fall due to the reallocation of activity across plants within an industry. Using disaggregated U.S. import data, we create a new measure of trade costs over time and industries. As the models predict, productivity growth is faster in industries with falling trade costs. We also find evidence supporting the major hypotheses of the heterogenous-firm models. Plants in industries with falling trade costs are more likely to die or become exporters. Existing exporters increase their shipments abroad. The results do not apply equally across all sectors but are strongest for industries most likely to be producing horizontally-differentiated tradeable goods.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This paper presents a model of international trade that features heterogeneous firms, relative endowment differences across countries, and consumer taste for variety. The paper demonstrates that firm reactions to trade liberalization generate endogenous Ricardian productivity responses at the industry level that magnify countries' comparative advantage. Focusing on the wide range of firm-level reactions to falling trade costs, the model also shows that, as trade costs fall, firms in comparative advantage industries are more likely to export, that relative firm size and the relative number of firms increases more in comparative advantage industries and that job turnover is higher in comparative advantage industries than in comparative disadvantage industries.

Available in PDF, EPUB and Kindle. Book excerpt: "We develop a stochastic, general equilibrium, two-country model of trade and macroeconomic dynamics. Productivity differs across individual, monopolistically competitive firms in each country. Firms face a sunk entry cost in the domestic market and both fixed and per-unit export costs. Only relatively more productive firms export. Exogenous shocks to aggregate productivity and entry or trade costs induce firms to enter and exit both their domestic and export markets, thus altering the composition of consumption baskets across countries over time. In a world of flexible prices, our model generates endogenously persistent deviations from PPP that would not exist absent our microeconomic structure with heterogeneous firms. It provides an endogenous, microfounded explanation for a Harrod-Balassa-Samuelson effect in response to aggregate productivity differentials and deregulation. Finally, the model successfully matches several moments of U.S. and international business cycles"--NBER website

Download or read book Firms in International Trade written by Andrew B. Bernard and published by . This book was released on 2007 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite the fact that importing and exporting are extremely rare firm activities, economists generally devote little attention to the role of firms when discussing international trade. This paper summarizes key differences between trading and non-trading firms, demonstrates how these differences present a challenge to standard trade models and shows how recent "heterogeneous-firm" models of international trade address these challenges. We then make use of transaction-level U.S. trade data to introduce a number of new stylized facts about firms and trade. These facts reveal that the extensive margins of trade -- that is, the number of products firms trade as well as the number of countries with which they trade -- are central to understanding the well-known role of distance in dampening aggregate trade flows.

Download or read book Trade Effects of Regional Standards Liberalization written by Silja Baller and published by World Bank Publications. This book was released on 2007 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study investigates trade effects of the regional liberalization of technical barriers to trade (TBTs) in the form of harmonization and mutual recognition agreements (MRAs) for testing procedures. The theoretical part of the paper is framed in terms of a heterogeneous firms approach. This paper adds to the existing literature by formalizing the effects of MRAs and harmonization initiatives on bilateral trade flows and by applying this new theoretical framework in the empirical part of the paper. The latter consists of a two-stage gravity estimation and investigates sectoral effects of TBT liberalization on parties to the agreement as well as excluded industrial and developing countries. It finds that MRAs have a strong positive influence on both export probabilities and trade volumes for partner countries. Regarding harmonization, results seem to suggest that the impact on parties to the agreement is negligible, however that on excluded OECD countries is large and positive. Third party developing countries do not seem to benefit from the market integration effect brought about by harmonization in other regions. Overall, effects on the probability that a new firm will export are much more pronounced than effects on the trade volumes of incumbent exporters.

Download or read book A Theory of Trade Liberalization and Innovations with Heterogeneous Firms written by Christian Rutzer and published by . This book was released on 2014 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper extends the firm heterogeneity model of Melitz (2003) by introducing a new concept of endogenous investments in process R&D. The novelty is that if a firm invests more in R&D its expected innovation return hazard rate stochastically dominates the return of less R&D investments. Due to this property, entrants invest more in R&D in response to trade liberalization. As a result, the aggregate productivity is affected by a reallocation of resources to more productive firms and a simultaneous increase in firms' investments in innovations, which is consistent with empirical findings. At the same time the firms' increased R&D investments lead to a sector distribution with a higher right-tail compared to the distribution prior to trade liberalization. Hence, the model gives an explanation for the empirically found differences in the distribution tails among sectors with different trade openness levels. Another advantage of this paper's framework compared to other trade models with innovations is its foundation in and extension of Melitz (2003). It enables most of the heterogeneous firms trade models to be extended by endogenous firm-level R&D in an empirically relevant and analytically tractable way.
