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). The idea is that specialization allows countries to reap greater economies of scale (i.e. The forgone opportunities of production are key to understand this concept. Journal of Political Economy, 112(1), 48-67. doi:1. The chart here shows the estimated distribution of total welfare gains across the household income distribution (the light-gray lines correspond to confidence intervals). The evolutions of international trade and investment become more and more important for understanding the global economic and political landscape. 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. The data hubs from several large international organizations publish and maintain extensive cross-country datasets on international trade. Firms around the world import goods and services, in order to use them as inputs to produce goods and services that are later exported. Heres a list of the most important ones: In addition to these sources, there are also many other academic projects that publish data on international trade. 6, Bloom, Draca and Van Reenen (2016) examined the impact of rising Chinese import competition on European firms over the period 1996-2007, and obtained similar results.

International trade: What you need to know this month, Countries must forge Global Blue Deal to protect the ocean: UNCTAD, Global Alliance for Trade Facilitation streamlines international trade, Regional integration is key to economic growth. 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). The long and short of the Canada-US free trade agreement. As we can see, there is a strong negative relationship. Indeed, Ildik Magyari recently found evidence suggesting the Chinese trade shock provided incentives for US firms to diversify and reorganize production.10. The online access is here. The next graph, from Broadberry and ORourke (2010)21, shows another perspective on the integration of the global economy and plots the evolution of three indicators measuring integration acrossdifferent markets specifically goods, labor, and capital markets. 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 1990, the share was about 25%. This is no consolation to people who lost their job. 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. Yet the baker probably has a comparative advantage in baking, because the opportunity cost of baking is much higher for the pilot.

World trade values today have ballooned by almost 400 times from 1950 levels. The OECDs Balanced International Merchandise Trade Statistics, for example, uses its own approach to correct and reconcile international merchandise trade statistics.43. 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.

(2004). This pattern of trade is important because the scope for specialization increases if countries are able to exchange intermediate goods (e.g. (NB. 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). If you add the Netherlands, for example, you will see how important the Dutch Golden Age was. In the Sources tab in the chart you find a full explanation of how we constructed all series, as well as links to the original raw data. The world's current MFN applied tariffs stand at an average of 9%. Bloom, N., Draca, M., & Van Reenen, J. These are proportional gains, and are expressed as percent of initial household income. The world-wide expansion of trade after the Second World War was largely possible because of reductions in transaction costs stemming from technological advances, such as the development of commercial civil aviation, the improvement of productivity in the merchant marines, and the democratization of the telephone as the main mode of communication. As we explain below, part of the asymmetries in trade data come from the fact that, although merchandise and goods are equivalent in the dictionary, these two terms often measure related but different things. Trade is calculated as average of exports and imports, and excludes significant re-exports or imports for re-exports. differences between statistical territories and actual country borders, which do not often coincide because of things like custom free zones).42. cars). Preferential attachment, R&D expenditure and the evolution of Is globalization an engine of economic development? Handbook of economic growth, 1, 1419-1497.

Chapter 1 "Introduction", Section 1.4 "The Globalization Debate" discussed how Thomas Friedman's flat-world approach segments history into three stages: Globalization 1.0 from 1492 to 1800, 2.0 from 1800 to 2000, and 3.0 from 2000 to the present.

The second wave started after the Second World War, and is still continuing. You can use the option labeled change country, at the bottom of the chart, to focus on any country. 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).
