Available in PDF, EPUB and Kindle. Book excerpt: How do trade costs affect international trade? This paper offers a new approach. We rely on a flexible gravity equation that predicts variable trade cost elasticities, both across and within country pairs. We apply this framework to popular trade cost variables such as currency unions, trade agreements, and WTO membership. While we estimate that these variables are associated with increased bilateral trade on average, we find substantial heterogeneity. Consistent with the predictions of our framework, trade cost effects are strong for 'thin' bilateral relationships characterised by small import shares, and weak or even zero for 'thick' relationships.

Download or read book Gravity and Comparative Advantage written by Kari E. R. Heerman and published by . This book was released on 2018 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this paper, a structural gravity model is presented which features intra-sector heterogeneity in agricultural productivity systematically linked to land and climate characteristics. The "systematic heterogeneity" (SH) gravity model predicts that countries with similar land and climate characteristics tend to specialize in the same agricultural products. Agricultural trade flow elasticities then depend on comparative advantage, with larger-magnitude trade flow responses predicted among countries more likely to specialize in similar agricultural products and thus compete head-to-head in foreign markets. This is in contrast to standard log-linear gravity models, which impose a restrictive pattern of trade flow elasticities that depend only on absolute advantage in the agricultural sector. We also show how the SH gravity model can accommodate product-specific trade costs. This allows the model to analyze changes in the dispersion of trade costs across products. Such analysis cannot be carried out in a standard gravity model, in which trade costs are assumed constant. Our results confirm economically and statistically significant heterogeneity in the effects of the variables that typically proxy for trade costs in gravity models and demonstrate that the SH gravity model is able to overcome the limitations imposed by the restrictive pattern of elasticities in a standard gravity model.

Available in PDF, EPUB and Kindle. Book excerpt: We show that statistically and economically significant heterogeneity exists in the distance elasticity in trade gravity models. Distance elasticities critically depend on whether trading partners belong to the OECD and whether they are Christian or Islam countries.
Download or read book From Micro to Macro written by Maria Bas and published by . This book was released on 2015 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: Models of heterogeneous firms with selection into export market participation generically exhibit aggregate trade elasticities that vary across country-pairs. Only when heterogeneity is assumed Pareto-distributed do all elasticities collapse into an unique elasticity, estimable with a gravity equation. This paper provides a theory-based method for quantifying country-pair specific elasticities when moving away from Pareto, i.e. when gravity does not hold. Combining two firm-level customs datasets for which we observe French and Chinese individual sales on the same destination market over the 2000-2006 period, we are able to estimate all the components of the dyadic elasticity: i) the demand-side parameter that governs the intensive margin and ii) the supply side parameters that drive the extensive margin. These components are then assembled under theoretical guidance to calculate bilateral aggregate elasticities over the whole set of destinations, and their decomposition into different margins. Our predictions fit well with econometric estimates, supporting our view that micro-data is a key element in the quantification of non-constant macro trade elasticities.
Download or read book Understanding Globalization Through the Lens of Gravity written by Jeffrey H. Bergstrand and published by World Scientific Publishing Company. This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since 1962, economists have used the "gravity equation" in international trade to explain empirically bilateral international trade flows, and have since more recently adopted the gravity model to explain foreign direct investment stocks. Motivated by its empirical success, Jeffrey H. Bergstrand provided one of the earliest formal theoretical foundations for the gravity equation in international trade in 1985. Since then, the gravity equation has become a fundamental element of international trade theory, empirical work, and policy analysis, especially of the effects of economic integration agreements and tariffs on trade flows and welfare. Understanding Globalization Through the Lens of Gravity is a curated collection of Bergstrand's published papers over the 30 years since his first paper on the theme of gravity. In four parts, the 17 papers span topics such as the determinants of international trade flows, economic determinants of free trade agreements, estimating the effects of economic integration agreements on trade flows, and economic determinants of multinational firms' foreign direct investment stocks, foreign affiliate sales and governments' bilateral investment treaties.

Download or read book A Practical Guide to Trade Policy Analysis written by Marc Bacchetta and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Trade flows and trade policies need to be properly quantified to describe, compare, or follow the evolution of policies between sectors or countries or over time. This is essential to ensure that policy choices are made with an appropriate knowledge of the real conditions. This practical guide introduces the main techniques of trade and trade policy data analysis. It shows how to develop the main indexes used to analyze trade flows, tariff structures, and non-tariff measures. It presents the databases needed to construct these indexes as well as the challenges faced in collecting and processing these data, such as measurement errors or aggregation bias. Written by experts with practical experience in the field, A Practical Guide to Trade Policy Analysis has been developed to contribute to enhance developing countries' capacity to analyze and implement trade policy. It offers a hands-on introduction on how to estimate the distributional effects of trade policies on welfare, in particular on inequality and poverty. The guide is aimed at government experts engaged in trade negotiations, as well as students and researchers involved in trade-related study or research. An accompanying DVD contains data sets and program command files required for the exercises. Copublished by the WTO and the United Nations Conference on Trade and Development
Download or read book Aggregate Implications of Firm Heterogeneity written by Rodrigo Adão and published by . This book was released on 2020 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: We measure the role of firm heterogeneity in counterfactual predictions of monopolistic competition trade models without parametric restrictions on the distribution of firm fundamentals. We show that two bilateral elasticity functions are sufficient to nonparametrically compute the counterfactual aggregate impact of trade shocks, and recover changes in economic fundamentals from observed data. These functions are identified from two semiparametric gravity equations governing the impact of bilateral trade costs on the extensive and intensive margins of firm-level exports. Applying our methodology, we estimate elasticity functions that imply an impact of trade costs on trade flows that falls when more firms serve a market because of smaller extensive margin responses. Compared to a baseline where elasticities are constant, firm heterogeneity amplifies both the gains from trade in countries with more exporter firms and the welfare gains of European market integration in 2003-2012.
Download or read book Trade Costs and Provincial Heterogeneity in Italy written by Michele U. Fratianni and published by . This book was released on 2014 with total page 26 pages. Available in PDF, EPUB and Kindle. Book excerpt: We test the hypothesis that higher economic development is associated with lower trade costs. Using different methods to control for multilateral resistance, we apply two alternative gravity equations (GE). In the first, we estimate total exports from 103 Italian provinces to 188 countries over the period 1995-2004. In the second, we estimate sectoral exports and then construct provincial trade cost elasticities. Italian provinces are heterogeneous with respect to trade costs. The two versions of GE are qualitatively the same but quantitatively different suggesting that other factors than trade costs are at play, possibly agglomeration externalities.
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.
Download or read book Elasticity Optimism written by International Monetary Fund and published by International Monetary Fund. This book was released on 2009-12-01 with total page 47 pages. Available in PDF, EPUB and Kindle. Book excerpt: In most macroeconomic models, the substitutability between domestic and foreign goods is calibrated using aggregated data. This imposes homogeneous elasticities across goods, and the calibration is only valid under this assumption. If elasticities are heterogeneous, the aggregate substitutability is a weighted average of good-specific elasticities, which in general cannot be inferred from aggregated data. We identify structurally the substitutability in US goods using multilateral trade data. We impose homogeneity, and find an aggregate elasticity similar in value to conventional macroeconomic estimates. It is more than twice larger with sectoral heterogeneity. We discuss the implications in various areas of international economics.
Download or read book The Gravity Model in International Trade written by Peter A. G. van Bergeijk and published by Cambridge University Press. This book was released on 2010-06-10 with total page 373 pages. Available in PDF, EPUB and Kindle. Book excerpt: How do borders affect trade? Are cultural and institutional differences important for trade? Is environmental policy relevant to trade? How does one's income or wage relate to the fact that trade partners are nearby or far away? These are just some of the important questions that can be answered using the gravity model of international trade. This model predicts and explains bilateral trade flows in terms of the economic size and distance between trading partners (e.g. states, regions, countries, trading blocs). In recent years, there has been a surge of interest in this model and it is now one of the most widely applied tools in applied international economics. This book traces the history of the gravity model and takes stock of recent methodological and theoretical advances, including new approximations for multilateral trade resistance, insightful analyses of the measurement of economic distance and analyses of foreign direct investment.
Download or read book Distorted Trade Barriers written by Tibor Besedes and published by . This book was released on 2017 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is common in the trade literature to use iceberg transport costs to represent both tariffs and shipping costs alike. However, in models with monopolistic competition these are not identical trade restrictions. This difference is driven by how the two costs affect the extensive margin. We illustrate these differences in a gravity model. We show theoretically that trade flows are more elastic with respect to tariffs than transport costs and find a linear relationship between the elasticities with respect to tariffs, iceberg transport costs, and fixed market costs. We empirically validate these results using data on US product-level imports.
Download or read book New Perspectives on Global Governance written by Michele Fratianni and published by Ashgate Publishing, Ltd.. This book was released on 2005 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: A unique collection of new writing examining the role of the G8 Summit after it celebrated its 30th anniversary in 2004. New Perspectives on Global Governance challenges the assumption that the G8 is simply a forum for binding a unilateralist hegemonic America. Economic recession following the September 11th terrorist attacks, bitter divisions with its NATO allies and disappointments with the UN over the 2003 Iraq War means a more vulnerable America must rely on the G8 as a central instrument of foreign policy to achieve its security, economic and political interests in an increasingly uncertain world.
