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 The Oxford Handbook of Computational Economics and Finance written by Shu-Heng Chen and published by Oxford University Press. This book was released on 2018 with total page 785 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Oxford Handbook of Computational Economics and Finance provides a survey of both the foundations of and recent advances in the frontiers of analysis and action. It is both historically and interdisciplinarily rich and also tightly connected to the rise of digital society. It begins with the conventional view of computational economics, including recent algorithmic development in computing rational expectations, volatility, and general equilibrium. It then moves from traditional computing in economics and finance to recent developments in natural computing, including applications of nature-inspired intelligence, genetic programming, swarm intelligence, and fuzzy logic. Also examined are recent developments of network and agent-based computing in economics. How these approaches are applied is examined in chapters on such subjects as trading robots and automated markets. The last part deals with the epistemology of simulation in its trinity form with the integration of simulation, computation, and dynamics. Distinctive is the focus on natural computationalism and the examination of the implications of intelligent machines for the future of computational economics and finance. Not merely individual robots, but whole integrated systems are extending their "immigration" to the world of Homo sapiens, or symbiogenesis.
Download or read book The Intensive Margin in Trade written by Ana Fernandes and published by International Monetary Fund. This book was released on 2018-12-07 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Melitz model highlights the importance of the extensive margin (the number of firms exporting) for trade flows. Using the World Bank’s Exporter Dynamics Database (EDD) featuring firm-level exports from 50 countries, we find that around 50 percent of variation in exports is along the extensive margin—a quantitative victory for the Melitz framework. The remaining 50 percent on the intensive margin (exports per exporting firm) contradicts a special case of Melitz with Pareto-distributed firm productivity, which has become a tractable benchmark. This benchmark model predicts that, conditional on the fixed costs of exporting, all variation in exports across trading partners should occur on the extensive margin. We find that moving from a Pareto to a lognormal distribution allows the Melitz model to match the role of the intensive margin in the EDD. We use likelihood methods and the EDD to estimate a generalized Melitz model with a joint lognormal distribution for firm-level productivity, fixed costs and demand shifters, and use “exact hat algebra” to quantify the effects of a decline in trade costs on trade flows and welfare in the estimated model. The welfare effects turn out to be quite close to those in the standard Melitz-Pareto model when we choose the Pareto shape parameter to fit the average trade elasticity implied by our estimated Melitz-lognormal model, although there are significant differences regarding the effects on trade flows.

Available in PDF, EPUB and Kindle. Book excerpt: What conclusions can be drawn from recent advances in international trade and international macroeconomics? New datasets, theoretical models, and empirical studies have resulted in fresh questions about the world trade and payment system. These chapters--six on trade and six on international macroeconomics--reveal the richness that researchers have uncovered in recent years. The chapters on foreign trade present, among other subjects, new integrated multisector analytical frameworks, the use of gravity equations for the estimation of trade flows, the role of domestic institutions in shaping comparative advantage, and international trade agreements. On international macroeconomics, chapters explore the relation between exchange rates and other macroeconomic variables; risk sharing, allocation of capital across countries, and current account dynamics; and sovereign debt and financial crises. By addressing new issues while enabling deeper and sharper analyses of old issues, this volume makes a significant contribution to our understanding of the global economy. Systematically illuminates and interprets recent developments in research on international trade and international macroeconomics Focuses on newly developing questions and opportunities for future research Presents multiple perspectives on ways to understand the global economy

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.
Download or read book Trade Theory in Computable General Equilibrium Models written by Peter B. Dixon and published by Springer. This book was released on 2018-03-30 with total page 194 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is for people who want to understand modern trade theory, particularly the Melitz model. It lays out Melitz theory from first principles and relates it to earlier theories of Armington and Krugman. For trade theory specialists, the book produces some significant conclusions. It identifies conditions under which Krugman and Melitz models produce essentially the same results for the welfare effects of trade liberalization as those obtained from Armington, and conditions under which this is not true. These findings will be of interest to academics and policy advisors who need to understand critiques of Armington by proponents of Krugman and Melitz. For computable general equilibrium (CGE) modelers, the book shows how Melitz-style CGE models can be calibrated, solved and interpreted. A major practical contribution of the book is to show how large-scale Armington models such as GTAP can be converted to Melitz by the addition of a small number of equations and minimal alteration of the original Armington model. The book describes computational experience in solving Melitz CGE models using GEMPACK software. This experience will be of interest to researchers currently attempting to solve Melitz-based CGE models. Almost all previous Melitz studies have used GAMS software. Authors of these studies have reported computational difficulties. These difficulties did not occur in this book’s GEMPACK-based computations. The book concludes that: (a) CGE modelers can embrace Melitz while retaining their Armington-based models as powerful interpretive devices; and (b) via GEMPACK, large-scale CGE models incorporating Melitz specifications can be solved with no more difficulty than similar-dimensioned Armington models.

Download or read book Economics without Borders written by Laszlo Matyas and published by Cambridge University Press. This book was released on 2017-04-27 with total page 665 pages. Available in PDF, EPUB and Kindle. Book excerpt: If treated as a single economy, the European Union is the largest in the world, with an estimated GDP of over 14 trillion euros. Despite its size, European economic policy has often lagged behind the rest of the world in its ability to generate growth and innovation. Much of the European economic research itself often trails behind that of the USA, which sets much of the agenda in mainstream economics. This book, also available as open access, bridges the gap between economic research and policymaking by presenting overviews of twelve key areas for future economic policy and research. Written for the economists and policymakers working within European institutions, it uses comprehensive surveys by Europe's leading scholars in economics and European policy to demonstrate how economic research can contribute to good policy decisions, and vice versa, demonstrating how economics research can be motivated and made relevant by hot policy questions. This title is available as Open Access on Cambridge Core.
Download or read book International Trade and Unemployment written by Marco de Pinto and published by Springer Science & Business Media. This book was released on 2012-12-14 with total page 121 pages. Available in PDF, EPUB and Kindle. Book excerpt: Economic theory and empirical research confirm that the rising international integration caused an increase in aggregate income at least for the industrialized countries, although trade liberalization is no Pareto improvement. In the empirical literature, there is a consensus that the international integration implies a destruction of low-skilled job vacancies and an increase in income, while the conclusions are mixed concerning the implication for the overall unemployment rate. This book seeks to find theoretical explanations to these empirical regularities. The book poses three questions: What are the implications of trade liberalization for the labor market in the presence of trade unions if we account for both firm and worker heterogeneity? What are the implications of a redistribution policy if the government chooses unemployment benefits to partially compensate the losers of trade liberalization?, and what is the optimal redistribution scheme for trade gains if the government explicitly takes into account the consequences for the income distribution? This book presents a rigorous theoretical analysis to answer the questions posed. Beside the well-known firm-selection effect on goods markets caused by trade liberalization, a selection process on the labor market -the worker-selection effect - is presented. The book also argues that if welfare is measured in the traditional manner, i.e. income per capita, compensating the loser of trade liberalization by paying unemployment benefits decreases welfare, but the intensity of the reduction differs with respect to the chosen funding of the unemployment benefits. Another significant contribution of this book is that if the objective function of the government, i.e. the modified welfare function, includes both aggregate income and income inequality, the redistribution of trade gains can lead to an increase in welfare.
