The printed version is published in 3 volumes: Africa, Asia, Oceania – The Americas – Europe. We will always indicate the original source of the data in our documentation, so you should always check the license of any such third-party data before use and redistribution. To see the difference between comparative and absolute advantage, consider a commercial aviation pilot and a baker. Bloom, N., Draca, M., & Van Reenen, J. Trade-offs between the ______ and the future require weighing the ______ available today against what will be available tomorrow. Today, the majority of preferential trade agreements are between developing economies. Language and foreign trade. After the Second World War trade within Europe rebounded, and from the 1990s onwards exceeded the highest levels of the first wave of globalization. The production chains for these goods and services are becoming increasingly complex and global. In two separate companion posts we cover the link between globalization and jobs, and the link between globalization and inequality. export-to-GDP ratios). It required downloading trade data from many different sources, collecting the relevant series, and then standardising them so that the units of measure and the geographical territories were consistent. 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. As we can see, there is a net positive welfare effect across all income groups; but these improvements in welfare are regressive, in the sense that richer households gain proportionally more (about 7.5 percent gain compared to 5 percent).17, Evidence from other countries confirms this is not an isolated case – the expenditure channel really seems to be an important and understudied source of household welfare. You can plot trends by region using the option ‘ The freely available economics textbook The Economy: Economics for a Changing World explains this as follows: “A person or country has comparative advantage in the production of a particular good, if the cost of producing an additional unit of that good relative to the cost of producing another good is lower than another person or country’s cost to produce the same two goods.”. This movement takes place in two steps—the movement from E to C is the gain from exchange and the movement from C to C 1 is the gain from specialization. Foreign value added in trade peaked in 2010–2012 after two decades of continuous increase. (2016). If we consider all pairs of countries that engage in trade around the world, we find that in the majority of cases, there is a bilateral relationship today: Most countries that export goods to a country, also import goods from the same country. While wood is on the X axis, so it is equal to run. This is consistent with the fact that, after the global financial crisis, there has been a slowdown in the rate of growth of trade in goods and services, relative to global GDP. Online here. The fact that trade diminishes with distance is also corroborated by data of trade intensity within countries. Does trade cause growth?. We state the result in a general form and then provide an example. 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. Up to 1870, the sum of worldwide exports accounted for less than 10% of global output. 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. T.R. Yet the baker probably has a comparative advantage in baking, because the opportunity cost of baking is much higher for the pilot. Nobel laureate Paul Samuelson (1969) was once challenged by the mathematician Stanislaw Ulam: “Name me one proposition in all of the social sciences which is both true and non-trivial.” It was several years later than he thought of the correct response: comparative advantage. This result is important, because it shows that there are gains from trade. However, this dataset has low coverage across countries, and it only goes back to 2011. (NB. Understanding this transformative process is important because trade has generated gains, but it has also had important distributional consequences. The IMF Working Paper The Distribution of Gains from Globalization, by Marina Mendes Tavares and Valentin F. Lang, reveals that in rich economies, globalization still represents a source of economic growth, but the expected gains are lower than in poor and emerging market economies, where globalization increases economic well-being and reduces poverty. There are different ways of capturing this correlation. You find all these alternative overlapping sources in this comparison chart.). Why is the global openness index not exactly twice the value reported in the chart plotting global merchandise exports? In a similar way, if we look at country-level data from the last half century we find that there is also a correlation between economic growth and trade: countries with higher rates of GDP growth also tend to have higher rates of growth in trade as a share of output. 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. Another common source of measurement error relates to the inconsistent attribution of trade partners. Journal of the European Economic Association. You can see from the graph that food is on the Y access so it is equal to rise. Globally, trade in goods accounts for the majority of trade transactions. As can be seen, financially developed economies – those with more dynamic private credit markets – typically outperform exporters with less evolved financial institutions. You can use the option labeled ‘change country’, at the bottom of the chart, to focus on any country. Available at: https://www.researchgate.net/publication/49518195_Trading_Data_Evaluating_Our_Assumptions_and_Coding_Rules, The NBER-UN trade data and documentation is available at http://cid.econ.ucdavis.edu/data/undata/undata.html, Further information on CEPII’s methodology can be found at http://www.cepii.fr/PDF_PUB/wp/2016/wp2016-14.pdf. In today’s global economic system, countries exchange not only final products, but also intermediate inputs. American economic review, 89(3), 379-399. This new – and ongoing – wave of globalization has seen international trade grow faster than ever before. REFERENCES M.L. You can read more about it in this report: 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. But in practice this is rarely the case because of differences in valuation. There are large deviations from the trend (there are some low-exposure regions with big negative changes in employment); but the paper provides more sophisticated regressions and robustness checks, and finds that this relationship is statistically significant. In theory, for example, the exports of country A to country B should mirror the imports of country B from country A. But of course efficiency is not the only relevant consideration here. (NB. The corrections applied in the OECD’s ‘balanced’ series make this the best source for cross-country comparisons. You can add more series by clicking on the option ‘ Eaton, J., & Kortum, S. (2002). And they found evidence of efficiency gains through two related channels: innovation increased and new existing technologies were adopted within firms; and aggregate productivity also increased because employment was reallocated towards more technologically advanced firms.7. Trade liberalization, exit, and productivity improvements: Evidence from Chilean plants. 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. We can divide each by two and split them between the countries, this means that the US now gets 48 apples, and 11 papayas, and Mexico gets 15 apples, and 13 papayas. He finds railroads increased trade, and in doing so they increased real incomes (and reduced income volatility). 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. The chart shows the value of exports (goods plus services) in dollars, country by country. Economists usually distinguish between “general equilibrium consumption effects” (i.e. Pavcnik (2002) examined the effects of liberalized trade on plant productivity in the case of Chile, during the late 1970s and early 1980s. Colombia exports bananas to Europe because it has comparatively abundant tropical weather. Is trade a major driver of income inequality? In this blog post we cover the link between globalization and economic growth. Exporting is a form of international trade which allows for specialization, but can be difficult depending on the transaction. Are these mechanisms supported by the data? The so-called trade openness index is an economic metric calculated as the ratio of country’s total trade (the sum of exports plus imports) to the country’s gross domestic product. ADVERTISEMENTS: “A country gains by foreign trade, if and when, the traders find that there exists abroad […] 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. For example, in a recent high-profile report, researchers attributed mismatches in bilateral trade data to illicit financial flows through trade misinvoicing (or trade-based money laundering). changes in consumption that arise from the fact that trade affects the prices of non-traded goods relative to traded goods) and “general equilibrium income effects” (i.e. Online here. There are many papers that try to answer this specific question with macro data. To sum up, the total gain from trade is comprised of gain from exchange and the gain from specialization. Available online here. She found a positive impact on firm productivity in the import-competing sector. This basic correlation is shown in the chart below, where I plot average annual change in real GDP per capita, against growth in trade (average annual change in value of exports as a share of GDP).3. Sources of Gain: According to the classical theory, specialisation based on the principle of comparative costs advantage is the major source of gain from international trade. The first approach relies on estimating trade from, The second approach relies on estimating trade from. The Review of Economic Studies, 69(1), 245-276. Online here. ‘Non-rich countries’ are all the other countries in the world. And they would both be able to get right over there. Leonor Freire Costa, Nuno Palma, and Jaime Reis, who compiled and published the original data shown here, argue that trade, also in this period, had a substantial positive impact on the economy.20. This creates an intricate network of economic interactions that cover the whole world. To illustrate, we have plotted CEPII’s national and dyadic trade estimates of the total value of exports from each country to the rest of the world. Broadberry and O’Rourke (2010) – The Cambridge Economic History of Modern Europe: Volume 2, 1870 to the Present. the value of merchandise trade as a share of global economic output). This figure shows the increasingly important role of trade between developing countries (South-South trade), vis-a-vis trade between developed and developing countries (North-South trade). Leonor Freire Costa, Nuno Palma, and Jaime Reis (2015) – The great escape? But, in economics terms, this can mean something a little more complex. 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. The Quarterly Journal of Economics, 119(2), 613-646. This means that job losses in some regions subsidized new jobs in other parts of the country. Donaldson, D. (2018). When a country opens up to trade, the demand and supply of goods and services in the economy shift. Even when two sources have identical trade estimates, inconsistencies in published data can arise from differences in exchange rates. On the whole, the available evidence suggests trade liberalization does improve economic efficiency. These numbers include notified and non-notified preferential agreements (the source reports that only about two-thirds of the agreements currently in force have been notified to the WTO), and are disaggregated by country groups. Trade and productivity. In other countries the opposite is true: In Nigeria and Venezuela services accounted for around 2% and 3% of exports, respectively, in 2014. You can learn more about New Trade Theory, and the empirical support behind it, in Krugman’s Nobel lecture. Add country Which is a situation that was unattainable left to their own production possibilities. You can explore country-specific time series by clicking on a country, or by using the ‘Chart’ tab. If trade is causally linked to economic growth, we would expect that trade liberalization episodes also lead to firms becoming more productive in the medium, and even short run. Indeed, international organizations often incorporate corrections, in an attempt to improve data quality along these lines. The same logic applies to countries. The idea is that a country’s geography is fixed, and mainly affects national income through trade. Berlingieri, G., Breinlich, H., & Dhingra, S. (2018). By looking at the difference in rise/run we get -.5, which is equal to our opportunity cost or trade … Estimating trade flows: Trading partners and trading volumes (No. The Quarterly Journal of Economics, 131(3), 1113-1180. This is the approach followed in Atkin, Faber, and Gonzalez-Navarro (2018): “Retail globalization and household welfare: Evidence from Mexico”.16. Bernhofen and Brown (2004)25, for instance, provide evidence using the experience of Japan. This chart shows an extraordinary growth in international trade over the last couple of centuries: Exports today are more than 40 times larger than in 1913. Consider the example of trade in two goods, shoes and refrigerators, between the United States and Mexico. The indicators in this chart are indexed, so they show changes relative to the levels of integration observed in 1900. ’. The empirical evidence shows that comparative advantage is indeed relevant; but it is not the only force driving incentives to specialization and trade. The gains obtained from market exchanges can be illustrated using the exhibit to the right. Here is the same chart but showing imports, rather than exports.). They found that innovation increased more in those firms most affected by Chinese imports. 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). 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 list of modules is expected to grow over time. Porto (2006) looks at the distributional effects of. The fact that trade negatively affects labor market opportunities for specific groups of people does not necessarily imply that trade has a negative aggregate effect on household welfare. In this paper Topalova looks at the impact of trade liberalization on poverty across different regions in India, using the sudden and extensive change in India’s trade policy in 1991. (NB. Available at http://correlatesofwar.org and (ii) Barbieri, Katherine, Omar M. G. Keshk, and Brian Pollins. all values have been adjusted to correct for inflation). The integration of global value chains is a common source of measurement error in trade data, because it makes it hard to correctly attribute the origin and destination of goods and services. US Census Bureau, Center for Economic Studies. For some households, the net effect is positive. Essentially, free trade enables lower prices for consumers, increased exports, benefits from economies of scale and a greater choice of goods. As we can see, up until the Second World War the majority of trade transactions involved exchanges between this small group of rich countries. Online here. By comparing opportunity costs and gains from trade for two parties each making the same two goods, one can determine the exact exchange ratio at which the parties should agree to trade. This interactive chart shows trade in services as share of GDP across countries and regions.). Globally, trade in goods accounts for the majority of trade transactions. A gain from trade is a simple concept - two parties traded and both parties got something out of it. The evidence from India shows that (i) discussions that only look at “winners” in poor countries and “losers” in rich countries miss the point that the gains from trade are unequally distributed within both sets of countries; and (ii) context-specific factors, like worker mobility across sectors and geographic regions, are crucial to understand the impact of trade on incomes. Frankel, J. 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. differences between statistical territories and actual country borders, which do not often coincide because of things like ‘custom free zones’).42. 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.

Rothwell’s critique received some attention from the media, but Autor and coauthors provided a reply, which I think successfully refutes this claim. 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. The Canadian Journal of Economics / Revue Canadienne D’Economique, 43(1), 41-62. Alcalá, F., & Ciccone, A. Hopefully the discussion and checklist above can help researchers better interpret and choose between conflicting data sources. These historical estimates obviously come with a large margin of error (in the measurement section below we discuss the data limitations); yet they offer an interesting perspective. (2017). So if we observe that a country’s distance from other countries is a powerful predictor of economic growth (after accounting for other characteristics), then the conclusion is drawn that it must be because trade has an effect on economic growth. This evidence comes from different political and economic contexts, and includes both micro and macro measures of efficiency. The Quarterly journal of economics, 119(2), 613-646. The concept of comparative advantage predicts that if all countries had identical endowments and institutions, then there would be little incentives for specialization, because the opportunity cost of producing any good would be the same in every country. 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. Differences in underlying records: is trade measured from National Accounts data rather than directly from custom or tax records? Using Survey Data to Assess the Distributional Effects of Trade Policy. This has an impact on households, both as consumers and as wage earners. Trade and productivity. Melitz, J. The idea is that a country’s geography is fixed, and mainly affects national income through trade. 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. Expressing trade values as a share of GDP tells us the importance of trade in relation to the size of economic activity. the sum of the value of exports from all Western European countries, divided by total GDP in this region). Financial integration is measured using Feldstein–Horioka estimators of current account disconnectedness.’ This data is taken from: Bayoumi 1990; Flandreau and Rivière 1999; Bordo and Flandreau 2003; Obstfeld and Taylor 2003. Some key references here are: the link between globalization and inequality, correlation between economic growth and rising international trade, The Economy: Economics for a Changing World, https://core-econ.org/the-economy/book/text/18.html#1810-trade-and-growth. Online here. Many traded services make merchandise trade easier or cheaper—for example, shipping services, or insurance and financial services. The impact of Chinese imports on innovation, IT and productivity. changes in wages that arise from the fact that trade has an impact on the demand for specific types of workers, who could be employed in both the traded and non-traded sectors). At the individual level, comparative advantage explains why you might want to delegate tasks to someone else, even if you can do those tasks better and faster than them. Commodity market integration is measured by computing the ratio of exports to GDP. apples. A key example is Alcalá and Ciccone (2004).6, This body of evidence suggests trade is indeed one of the factors driving national average incomes (GDP per capita) and macroeconomic productivity (GDP per worker) over the long run.7. This is no consolation to people who lost their job. A., & Romer, D. H. (1999). Each country tells a different story. ADVERTISEMENTS: Some of the important factors that determine the gains from international trade are as follows: 1. Samuelson, Paul A. Frankel, J. The settings tab allows you to choose alternative product classes, trade flows choices, and the level of product aggregation. Figures correspond to export-to-GDP ratios (i.e. But it is necessary to add this perspective to the simplistic story of “trade with China is bad for US workers”. In 1990, the share was about 25%. In this interactive chart you can explore trends in trade openness over this period for a selection of European countries.). Several economists, most notably Paul Krugman, have developed theories of trade in which trade is not due to differences between countries, but instead due to “increasing returns to scale” – an economic term used to denote a technology in which producing extra units of a good becomes cheaper if you operate at a larger scale. goods in transit) are not considered to change the stock of material resources of a country, and are hence often excluded from the more narrow concept of ‘merchandise trade’. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). If all asymmetries were coming from CIF-FOB differences, then we should only see positive values in the chart (recall that, unlike FOB values, CIF values include the cost of transportation, so CIF values are larger). Exploitation of comparative advantage 2.2 Proo–ng the gains from trade Trade can always produce a more e¢ cient outcome than autarky. This reveals that, despite the great variation between countries, there is a common trend: Over the last couple of decades trade openness has gone up in most countries. 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. As we discuss in a companion blog post, the efficiency gains from trade are not generally equally shared by everyone. Through econometric modeling, the paper shows that this relationship is not just a correlation driven by other factors: their findings suggest that distance imposes a significant barrier to trade. The weight of trade in the US economy, for example, is much lower than in other rich countries. David, H., Dorn, D., & Hanson, G. H. (2013). – Bloom, N., Draca, M., & Van Reenen, J. (2004). Giuseppe Berlingieri, Holger Breinlich, Swati Dhingra, for example, investigate the consumer benefits from trade agreements implemented by the EU between 1993 and 2013; and they find that these trade agreements increased the quality of available products, which translated into a cumulative reduction in consumer prices equivalent to savings of €24 billion per year for EU consumers.18. Donaldson (2018) uses archival data from colonial India to estimate the impact of India’s vast railroad network. Even when two sources rely on the same broad accounting approach, discrepancies arise because countries fail to adhere perfectly to the protocols. Now draw a point to show why Chinese workers gain from trade with the United States. Following this logic, Frankel and Romer find evidence of a strong impact of trade on economic growth. Under autarky, Colombia would find it cheap to produce bananas relative to e.g. As we can see, intercontinental trade was very dynamic, with volumes varying considerably across time and from empire to empire. The colors reflect the percentage of firms which export to each specific country. (i) Frankel, J. At Our World in Data we have chosen to rely on CEPII as the main source for exploring long-run changes in international trade; but we also rely on World Bank and OECD data for up-to-date cross-country comparisons. (ii) Fajgelbaum, P. D., & Khandelwal, A. K. (2016). As we discuss in a companion blog post, the efficiency gains from trade are not generally equally shared by everyone. In addition Western Europe then started to increasingly trade with Asia, the Americas, and to a smaller extent Africa and Oceania. For any given year, we see that there is a lot of variation across countries. 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).2. As we can see, until 1800 there was a long period characterized by persistently low international trade – globally the index never exceeded 10% before 1800. In this study, Frankel and Romer used geography as a proxy for trade, in order to estimate the impact of trade on growth. Please consult our full legal disclaimer. She finds that rural regions that were more exposed to liberalization, experienced a slower decline in poverty, and had lower consumption growth. (2005). Label it 1. This leaves 12 apples and 9 papayas as the gain from trade. There is evidence suggesting this is often the case. This interactive chart shows trade in services as share of GDP across countries and regions.) Following this logic, Frankel and Romer find evidence of a strong impact of trade on economic growth. The Review of Economic Studies, 69(1), 245-276. The following visualization shows a detailed overview of Western European exports by destination. Let’s dig deeper to understand what’s going on. The forgone opportunities of production are key to understand this concept. (NB. Considering all these complex interrelations, it’s not surprising that economic theories predict that not everyone will benefit from international trade in the same way. Trefler (2004) looks at the Canada-US Free Trade Agreement and finds there was a group who bore “adjustment costs” (displaced workers and struggling plants) and a group who enjoyed “long-run gains” (consumers and efficient plants). 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. Label it 3. law enforcement); but some are less obvious. Specifically, they exploit Japan’s dramatic nineteenth-century move from a state of near complete isolation to wide trade openness.
