The chart here shows the estimated distribution of total welfare gains across the household income distribution (the light-gray lines correspond to confidence intervals). Because distributional concerns are real it is important to promote public policies – such as unemployment benefits and other safety-net programs – that help redistribute the gains from trade. Online here. The visualization presents a world map showing the trade openness index country by country. This exhibit presents a standard market graph. The chart above shows how much more trade we have today relative to a century ago. Many traded services make merchandise trade easier or cheaper—for example, shipping services, or insurance and financial services. The vertical position of the dots represents the percent change in manufacturing employment for working age population; and the horizontal position represents the predicted exposure to rising imports (exposure varies across regions depending on the local weight of different industries). The impact of Chinese imports on innovation, IT and productivity. In 1990, the share was about 25%. This is an excerpt from, Bernhofen, D., & Brown, J. American economic review, 89(3), 379-399. Different exchange rates will lead to conflicting estimates, even if figures in local currency units are consistent. The visualization here shows the share of world merchandise trade that corresponds to exchanges between today’s rich countries and the rest of the world. Help us do this work by making a donation. At some universities you can access the online version of the books where data tables can be downloaded as ePDFs and Excel files. Online here. Using Survey Data to Assess the Distributional Effects of Trade Policy. So Charlie could trade 15 cups for 15 plates and obviously Patty would be trading 15 plates for 15 cups. Railroads of the Raj: Estimating the impact of transportation infrastructure. Up to 1870, the sum of worldwide exports accounted for less than 10% of global output. But, in economics terms, this can mean something a little more complex. The solution to the paradox is actually not very complicated: Comparative advantage is one, but not the only force driving incentives to specialization and trade. This will help you see that, over the long run, growth has roughly followed an exponential path. For an overview of papers and methods see: Durlauf, S. N., Johnson, P. A., & Temple, J. R. (2005). Trade induced technical change? You can learn more about New Trade Theory, and the empirical support behind it, in Krugman’s Nobel lecture. In this entry we analyze available data and research on international trade patterns, including the determinants and consequences of globalization over the last couple of decades. This result is important, because it shows that there are gains from trade. This is an important obstacle, since the complex adjustments introduced by the OECD imply we can’t easily improve coverage by appending data from other sources. Integration in the goods markets is measured here through the ‘trade openness index’, which is defined by the sum of exports and imports as share of GDP. The first lesson is that, for most users of trade data out there, there is no obvious way of choosing between sources. Other studies have shown that country-specific institutions, like the knowledge of foreign languages, for instance, are also important to promote foreign relative to domestic trade (see Melitz 200831). Gains from trade are broadly divided into two types – Static gains and dynamic gains. US Census Bureau, Center for Economic Studies. The openness index, when calculated for the world as a whole, includes double-counting of transactions: When country A sells goods to country B, this shows up in the data both as an import (B imports from A) and as an export (A sells to B). The second wave started after the Second World War, and is still continuing. So companies that outsourced jobs to China often ended up closing some lines of business, but at the same time expanded other lines elsewhere in the US. And this is true, to varying degrees, across all countries and years. These goods are homogeneous, meaning that consumers and producers cannot differentiate between shoes from Mexico and shoes from the U.S.; nor can they differentiate between Mexican or American refrigerators.From Table 1, we can see that it takes four U.S. workers to produce 1,000 pairs of shoes, but it takes five Mexican workers to do so. Today about one fourth of total global production is exported. As we can see, there is a strong negative relationship. Available online here. ), The most famous study looking at this question is Autor, Dorn and Hanson (2013): “The China syndrome: Local labor market effects of import competition in the United States”.8. Among the potential growth-enhancing factors that may come from greater global economic integration are: Competition (firms that fail to adopt new technologies and cut costs are more likely to fail and to be replaced by more dynamic firms); Economies of scale (firms that can export to the world face larger demand, and under the right conditions, they can operate at larger scales where the price per unit of product is lower); Learning and innovation (firms that trade gain more experience and exposure to develop and adopt technologies and industry standards from foreign competitors).4. The settings tab allows you to choose alternative product classes, trade flows choices, and the level of product aggregation. Globalization, markups, and US welfare. Online here. This approach is problematic because it fails to consider welfare gains from increased product variety, and obscures complicated distributional issues such as the fact that poor and rich individuals consume different baskets so they benefit differently from changes in relative prices.15, Ideally, studies looking at the impact of trade on household welfare should rely on fine-grained data on prices, consumption and earnings. The higher the index, the higher the influence of trade transactions on global economic activity.19. In the second wave of globalization we are seeing a rise in intra-industry trade (i.e. ADVERTISEMENTS: Some of the important factors that determine the gains from international trade are as follows: 1. And the second lesson is that, because of statistical glitches, researchers and policymakers should always take analysis of trade data with a pinch of salt. Figures correspond to export-to-GDP ratios (i.e. The evidence from the impact of trade on firm productivity confirms this: “reshuffling workers from less to more efficient producers” means closing down some jobs in some places. 820-829. If, for example, Alpha ships 2,000 washing machines to Beta in exchange for 3,000 computers, then the two economies will move to points R 3 and S 3 , respectively, consuming more of both goods than they had before trade. (2004). (ii) Fajgelbaum, P. D., & Khandelwal, A. K. (2016). – Bloom, N., Draca, M., & Van Reenen, J. In this paper, Autor and coauthors looked at how local labor markets changed in the parts of the country most exposed to Chinese competition, and they found that rising exposure increased unemployment, lowered labor force participation, and reduced wages. In addition Western Europe then started to increasingly trade with Asia, the Americas, and to a smaller extent Africa and Oceania. Static gains from trade refer to the increase in production or welfare of the people of the trading countries as a result of the optimum allocation their given factor-endowments, if they specialise on the basis of their comparative costs. Other papers have applied the same approach to richer cross-country data, and they have found similar results. But this process of European integration then collapsed sharply in the interwar period. All series, except the two long-run series from CEPII and NBER-UN, were produced from data published by the sources in current US dollars, and then converted to GDP shares using a unique source (World Bank).38. The Review of Economic Studies, 69(1), 245-276. Porto (2006) looks at the distributional effects of. Eaton, J., & Kortum, S. (2002). In a graph of the PPC the opportunity cost of the good represented on the horizontal axis is measured as the slope on the PPC. It presents a scatter diagram of the net exports in 1869 graphed in relation to the change in prices from 1851–53 to 1869. The ‘normalized import shares’ in the vertical axis provide a measure of how much each country imports from different partners (see the paper for details on how this is calculated and normalised), while distance in the horizontal axis corresponds to the distance between central cities in each country (see the paper and references therein for details on the list of cities). American economic review, 89(3), 379-399. Melitz, J. The colors reflect the percentage of firms which export to each specific country. Economists usually distinguish between “general equilibrium consumption effects” (i.e. More information can be found at the IMF’s (2018) working paper on ‘New Estimates for Direction of Trade Statistics’. For an overview of papers and methods see: Durlauf, S. N., Johnson, P. A., & Temple, J. R. (2005). The following visualizations provides a comparison of intercontinental trade, in per capita terms, for different countries. The weight of trade in the US economy, for example, is much lower than in other rich countries. (2004). If the two countries trade at a rate of exchange of 2 digital cameras for one vacuum cleaner, the post-trade … So hopefully you found that interesting. The Quarterly Journal of Economics, 131(3), 1113-1180. In the chart we see a large drop in the interwar period. The printed version is published in 3 volumes: Africa, Asia, Oceania – The Americas – Europe. The impact of Chinese imports on innovation, IT and productivity. The fact that trade diminishes with distance is also corroborated by data of trade intensity within countries. Globally, trade in goods accounts for the majority of trade transactions. Each country tells a different story. Broadly speaking, the principle of comparative advantage postulates that all nations can gain from trade if each specializes in producing what they are relatively more efficient at producing, and import the rest: “do what you do best, import the rest”.24. As global production chains become more complex, countries find it increasingly difficult to unambiguously establish the origin and final destination of merchandise, even when rules are established in the manuals. Available online here. The contribution of the empire to Portugal’s economic growth, 1500–1800 Leonor Freire Costa Nuno Palma Jaime Reis European Review of Economic History, Volume 19, Issue 1, 1 February 2015, Pages 1–22, According to the BPM6, imports and exports should be recorded in the balance of payments accounts on a ‘free on board (FOB) basis’, which means using prices that include all charges up to placing the goods on board a ship at the port of departure. The next visualization plots the share of food exports in each country’s total exported merchandise. You have the permission to use, distribute, and reproduce in any medium, provided the source and authors are credited. It’s important to mention here that the economist Jonathan Rothwell recently wrote a paper suggesting these findings are the result of a statistical illusion. Online here. These studies also find that trade liberalization has led to growth in the productivity of firms. Trade induced technical change? There are many papers that try to answer this specific question with macro data. Differences in Cost Ratios: The gains from international trade depend on differences in comparative cost ratios in the two trading countries. This result is important because it shows that the labor market adjustments were large. Each dot is a small region (a ‘commuting zone’ to be precise). So households are affected both as consumers and as wage earners. (NB. The interactive data visualization, created by the London-based data visualisation studio Kiln and the UCL Energy Institute, gives us an insight into the complex nature of trade. That is, the share of the value of exports that comes from foreign inputs. The interactive chart here, from The Atlas of Economic Complexity, at the Centre for International Development in the Harvard Kennedy School, shows a breakdown of the United Kingdom’s total merchandise and service exports by product category, for 2018. Conducting international trade requires both financial and non-financial institutions to support transactions. Language and foreign trade. She found a positive impact on firm productivity in the import-competing sector. As the final step, the data are also converted to Classification of Products by Activity (CPA) products to better align with National Accounts statistics, such as in national Supply-Use tables.” You can read more about it here: In addition to the OECD, other sources also use corrections. As we can see, this is consistent with the theory: after opening to trade, the relative prices of major exports such as silk increased (Japan exported what was cheap for them to produce and which was valuable abroad), while the relative price of imports such as sugar declined (they imported what was relatively more difficult for them to produce, but was cheap abroad). In a much cited paper, Evenett and Keller (2002)33 show that both factor endowments and increasing returns help explain production and trade patterns around the world. Most trade theories in the economics literature focus on sources of comparative advantage. ‘Compilers guide on European statistics on international trade in goods’. Some of the most cited papers in this field (e.g. Here is the same chart, but showing imports rather than exports.). The following visualization, from the UN World Development Report (2009), plots the fraction of total world trade that is accounted for by intra-industry trade, by type of goods. Commodity market integration is measured by computing the ratio of exports to GDP. According to IMF data, for example, the value of goods that Canada reports exporting to the US is almost $20 billion more that the value of goods that the US reports importing from Canada. Online here. This evidence comes from different political and economic contexts, and includes both micro and macro measures of efficiency. Two points stand out. The main takeaway here are the country-specific trends, which are positive and more pronounced than in the charts showing shares of GDP. The visualization, from Eaton and Kortum (2002)27, graphs ‘normalized import shares’ against distance. Exploitation of comparative advantage 2.2 Proo–ng the gains from trade Trade can always produce a more e¢ cient outcome than autarky. Following this logic, Frankel and Romer find evidence of a strong impact of trade on economic growth. The data produced by third parties and made available by Our World in Data is subject to the license terms from the original third-party authors. Related research entries in Our World in Data: The integration of national economies into a global economic system has been one of the most important developments of the last century. A gain graph is a graph whose edges are labelled "invertibly", or "orientably", by elements of a group G. This means that, if an edge e in one direction has label g … Also, adding to the complexity, countries often rely on measurement protocols that are developed alongside these approaches and concepts that are not perfectly compatible to begin with. The imported goods and services incorporated in a country’s exports are a key indicator of economic integration – they tell us something about ‘global value chains’, where the different stages of the production process are located across different countries. This gives us another viewpoint to understand how quickly global integration collapsed with the two World Wars. Today, the majority of preferential trade agreements are between developing economies. Berlingieri, G., Breinlich, H., & Dhingra, S. (2018). Today, about 30% of the value of global exports comes from foreign inputs. The OECD’s Balanced International Merchandise Trade Statistics, for example, uses its own approach to correct and reconcile international merchandise trade statistics.43. These include conceptual inconsistencies across measurement standards, as well as inconsistencies in the way countries apply agreed protocols. Colombia is a notable case in point: food went from 77% of merchandise exports in 1962, to 15.9% in 2015. The trend line in this chart shows a negative relationship: more exposure goes together with less employment. Constructing this chart was demanding.

Balanced International Merchandise Trade Statistics, Bilateral Trade Historical Series: New Dataset 1827-2014, Dutch Data Archiving and Networked Services,, global merchandise exports as share of GDP,,,, Harrison, Anne (2013) FOB/CIF Issue in Merchandise Trade/Transport of Goods in BPM6 and the 2008 SNA, Twenty-Fifth Meeting of the IMF Committee on Balance of Payments Statistics, Washington, D.C,, In Italy, for example, Eurostat figures of the value of exported goods in 2015 are 10% higher than the merchandise trade figures published by the OECD. Using the option ‘relative’, at the bottom of the chart, you can see the proportional contribution of purchases from each region. 2.1 The sources of gains from trade 1. Klasing and Milionis (2014), which is one of the sources in the chart, published an additional set of estimates under an alternative specification. There are dozens of official sources of data on international trade, and if you compare these different sources, you will find that they do not agree with one another. So, if all series are in the same units (share of national GDP), and they all measure the same thing (value of goods exported from one country to the rest of the world), what explains the differences? In this chart, all possible country pairs are partitioned into three categories: the top portion represents the fraction of country pairs that do not trade with one-another; the middle portion represents those that trade in both directions (they export to one-another); and the bottom portion represents those that trade in one direction only (one country imports from, but does not export to, the other country). When it comes to academic studies estimating the impact of trade on GDP growth, the most cited paper is Frankel and Romer (1999).5. Pavcnik, N. (2002). The online access is here. The evidence from the impact of trade on firm productivity confirms this: “reshuffling workers from less to more efficient producers” means closing down some jobs in some places. This chart shows that growth in Western European trade throughout the 19th century was largely driven by trade within the region: In the period 1830-1900 intra-European exports went from 1% of GDP to 10% of GDP; and this meant that the relative weight of intra-European exports doubled over the period (in the ‘relative’ view you can see the changing composition of exports by destination, and you can check that the weight of intra-European trade went from about one third to about two thirds over the period). & Ciccone, a integration is measured by dividing the migratory turnover by population barriers trade.
