The pattern of trade
The pattern of world trade Trade is the exchange of goods and services between countries. Goods bought into a country are called imports, and those sold to another country are called exports. Patterns of trade evolve over time as countries develop and build new comparative advantage in both goods and services. One key change in global trade is the rise in South-South trade. According to the WTO, from , developing economies’ exports to other developing economies surpassed its exports to developed economies. “South-South” trade represented an estimated US$ trillion or 52% of total .
International trade is an exchange of goods or services across national jurisdictions. Inbound trade is defined as imports, and outbound trade is defined as exports. International trade is subject to the regulatory oversight and taxation of the involved nations, namely through customs. In a global economy, no nation is self-sufficient, which is associated with specific flows of goods, people, and information.
Each nation is involved at different levels in trade to sell what it produces, how many calories are in a chipotle burrito acquire what it lacks, and to produce more efficiently in some economic sectors than its trade partners.
International trade, or long-distance trade since there were no nations in the modern sense, has taken place for centuries. It is an important part of human economic and cultural history as ancient trade routes such as the Silk Road can testify and has occurred at an ever-increasing scale over the last years. Trade now plays an even more active part in the economic life of nations and regions, but it should be taking place only if there is a benefit for the partners involved.
International trade is an expansion of the market or exchange principle at a scale beyond the region or the nation. The rationale for trade can be a convenience but also a necessity.
It is for convenience, as supported by conventional economic theorywhen trade promotes economic efficiency by providing a wider variety of goods, often at lower costs. This is because of specialization, economies of scale, and the related comparative advantages.
Trade is a necessity when it enables a nation to acquire goods that would otherwise not be available in a national economy such as energy, raw minerals, or even some food. However, the benefits of trade can be subject to contention with several theoretical foundations of international trade have been articulated how to erase password on ipod touch explain its rationale:.
The globalization of production is concomitant to the globalization of trade as one cannot function without the other. This process has been facilitated by significant technical changes in the transport sector. The scalevolume, and efficiency of international trade have all continued to increase since the s. It has become increasingly possible to trade between parts of the world that previously had limited access to international transportation systems.
Further, the division and the fragmentation of production that went along with these processes also expanded trade. Trade thus contributes to lower manufacturing costs.
Without international trade, few nations could maintain an adequate standard of living, particularly those of smaller size. With only domestic resources being available, each country could only produce a limited number of products, and shortages would be prevalent. Global trade allows for an enormous variety of resources — from Persian Gulf oil, Brazilian coffee to Chinese labor — how to restring an acoustic bass be made more widely accessible.
It also facilitates the distribution of a wide range of manufactured goods that are produced in different how many calories have i eaten today australia of the world to global markets. Wealth becomes increasingly derived through the regional specialization of economic activities.
This way, production costs are lowered, productivity rises, and surpluses are generated, which can be transferred or traded for commodities that would be too expensive to produce domestically or would simply not be available. As a result, international trade decreases the overall costs of production. Consumers can buy more goods from the wages they earn, and standards of living should, in theory, increase.
International trade demonstrates the extent of globalization with increased spatial interdependencies between elements of the global economy and their level of integration. These interdependencies imply numerous relationships where flows of capital, goods, raw materials, people, and services are established between regions of the world.
International trade is also subject to much contention since it can, at times, be a disruptive economic and social force as it changes the conditions in which wealth is distributed within a national economy, particularly due to changes in prices, wages and employment sectors. One challenge concerns the substitution of labor and capital. While in simple economy labor and capital infrastructures can be reconverted to other uses, in complex economies, labor and capital cannot be easily reallocated.
Therefore, trade can, at the same time, lead to more goods being available at a lower price, but with enduring unemployment and decaying infrastructures unused factories and connectors. In turn, this can incite economies to adopt protectionist policies since this transition is judged to be too disruptive. International trade, both in terms of value and tonnage, has been a growing trend in the global economy. It is important to underline when looking at the structure of global trade that it is not nations that are trading, but mainly corporations with the end products consumed in majority by individuals.
A nation is simply a regulatory unit where data is collected since freight crossing boundaries are subject to customs oversight and tabulated as trade flows. Inter and Intra corporate trade is taking place across national jurisdictions is accounted for as international trade.
The emergence of the current structure of global trade can mainly be articulated within three major phases :. The global economic system is thus characterized by a growing level of integrated services, finance, retail, manufacturing, and distribution.
This is mainly the outcome of improved transport and logisticsmore efficient exploitation of regional comparative advantagesand a transactional environment supportive of the legal and financial complexities of global trade. International trade requires a full array of services related to distribution and transactions. The volume of exchanged goods and services between nations is taking a growing share of the generation of wealth, mainly by offering economic growth opportunities in new regions and by reducing the costs of a wide array of manufacturing goods.
The facilitation of trade involves how the procedures regulating the international movements of goods can be improved so that actors involved in international trade have move efficient formalities.
For regulatory authorities, trade facilitation improves their effectiveness as well as reducing the risk of customs duty evasion. It relies on the reduction of the general costs of trade, which considers transaction, tariff, transport, and time costs. These trade costs are derived from two main sources:. Thus, the ability to compete in a global economy is dependent on the transport system as well as a trade facilitation framework that includes measures related to economic integration, the capabilities of international transportation systems, and the ease to negotiate and settle transactions.
The quality, cost, and efficiency of trade services influence the trading environment as well as the overall costs linked with the international trade of goods. Many factors have been conductive to trade facilitation in recent decades, including integration processes, standardization, production systems, transport efficiency, and transactional efficiency:. All these measures are expected to promote the level of economic and social development of the concerned nations since trade facilitation relies on the expansion of human, infrastructure, and institutional capabilities.
The nature of what can be considered international trade has changed, particularly with the emergence of global value chains and the trade of intermediary goods they involve. This trend obviously reflects the strategies of multinational corporations positioning their manufacturing assets in what diesel truck has the best mpg to lower costs and maximize new market opportunities.
International trade has thus grown at a faster rate than global merchandise productionwith the growing complexity of distribution systems supported by supply chain what does carbohydrates do for your body practices.
The structure of global trade flows has shifted, with many developing economies having growing participation in international trade with an increasing share of manufacturing. Globalization has been accompanied by growing flows of manufactured goods and their growing share of international trade. The trend since the s involved a relative decline in bulk liquids such as oil and more dry bulk and general cargo being traded.
Recently, the share of fuels in international trade has increased, mainly due to rising energy demand and prices. Another emerging trade flow concerns the increase in the imports of resources from developing economies, namely energy, commodities, and agricultural products, which is a divergence from their conventional role as exporters of resources.
This is indicative of economic diversification as well as increasing standards of living. However, significant fluctuations in the growth rates of international trade are linked with economic cycles of growth and recession, fluctuations in the price of raw materials, as well as disruptive geopolitical and financial events.
The geography of international trade remains dominated by a few large economic blocsmainly in North America, Europe, and East Asiawhich are commonly referred to as the triad. Alone, the United States, Germany, and Japan account for about a quarter of all global trade, with this supremacy being seriously challenged by emerging economies. Further, G7 countries account for half of the global trade, a dominance that has endured for over years. A growing share is being accounted how to smooth rough concrete by the developing economies of Asia, with China accounting for the most significant growth both in absolute and relative terms.
Those geographical and economic changes are also reflected in trans-oceanic trade, with the Trans-Pacific trade growing faster than the Trans-Atlantic trade.
Neo-mercantilism is reflective of global trade flows as several countries have been actively pursuing export-oriented economic development policies using infrastructure development, subsidies, and exchange rates as tools. This strategy has been followed by developing economies and is associated with growing physical and capital flow imbalances in international trade. This is particularly reflective in the American container trade structure, which is highly imbalanced and having acute differences in the composition of imports and exports.
A large share of these imbalances was the outcome of the fiscal policies of exporting countries purchasing American financial instruments, such as bonds. This enabled the US dollar to uphold its value and purchasing power. Imbalances can also be misleading as products are composed of parts manufactured in several locations with assembly often taking place in low-cost locations and then exported to major consumption markets.
In international trade statistics, a location assumes the full value of finished goods imported elsewhere while it may have only contributed to a small share of what are self- evident truths total added value.
Electronic devices are illustrative of this issue. Trade imbalances also do not reflect well the utility an economy derive from it, such as cheaper goods for consumers. Further, the growth of e-commerce has resulted in new actors to be involved in international trade, at times indirectly. For instance, ordering a product online may result in an international trade transaction controlled by a single corporation.
Regionalization has been one of the dominant features of global trade as the bulk of trade has a regional connotation, promoted by proximity and the setting of economic blocs such as NAFTA and the European Union.
The closer economic entities are, the more likely they are to trade due to lower transport costs, fewer potential delays in shipments, common customs procedures, and linguistic and cultural affinities. The most intense trade relations are within Western Europe and North America, with a more recent trend involving trade within Asia, particularly between Japan, China, Korea, and Taiwan as these economies were getting more integrated.
At the beginning of the 21st century, the flows of globalization have been shaped by four salient trends:. Still, many challenges are impacting future developments in international trade and transportation, mostly in terms of demographics, political, supply chain, energy, and environmental issues.
While the global population and its derived demand will continue to grow and reach around 9 billion bydemographic changes such as the aging of the population, particularly in developed economies, will transform consumption patterns as a growing share of the population shifts from wealth-producing working and saving to wealth consuming selling saved assets. Japan, South Korea, Taiwan may not place them as drivers of global trade, a function they have assumed in recent decades.
The demographic dividend in terms of peak share of the working-age population that many countries benefited from, particularly China, will recede. The regulatory environment and the involvement of governments, either directly or indirectly, is subject to increasing contention. Reforms in agricultural trade have not been effectively carried on, implying that many governments e. This is undertaken with the intent to protect their agriculture, considering the risks what is the clients list about with dependency on foreign providers and possible fluctuations in prices.
Intellectual property rights remain a contentious issue as well since many goods are duplicated, undermining the brands of major manufacturers and retailers. There is also a whole array of subsidies that influence the competitiveness of exports, such as low energy and land costs and tax reductions.
The rise of protectionist policies, as exemplified by higher tariffs imposed by the American government on several Chinese goods, is underlining a contentious trade environment. As both maritime and air freight transportation depend on petroleum, international trade remains influenced by fluctuations in energy prices. The paradox has become that periods of high energy prices usually impose a rationalization of international trade and its underlying supply chains.
However, periods of low or sharply declining energy prices, which should benefit international transportation, are linked with economic recessions. Environmental issues have also become more salient with the growing tendency of the public sector to regulate components of international transportation that are judged to have negative externalities.
International trade enables several countries to mask their energy consumption and pollutant emissions by importing goods that are produced elsewhere and where environmental externalities are generated. Thus, international trade has permitted a shift in the international division of production, but also a division between the generation of environmental externalities and the consumption of the goods related to these externalities.
Technological changes are impacting the nature of manufacturing systems through robotization and automation.
The pattern of trade. The global economy has grown continuously since the Second World War. Global growth has been accompanied by a change in the pattern of trade, which reflects ongoing changes in structure of the global economy. These changes include the rise of regional trading blocs, deindustrialisation in many advanced economies, the increased participation of former communist countries, and the emergence of China and India. In addition to patterns of trade, other important global economic relationships can be mapped by geographers and these include: Patterns of outsourcing: Outsourcing is obtaining key products from alternative, cheaper locations - often abroad - than Patterns of foreign direct investment. World Trade Usually developed countries export valuable manufactured goods such as electronics and cars and import cheaper primary products such as tea and coffee. In developing countries the.
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.
Here is an overview of the main points we cover below. The integration of national economies into a global economic system has been one of the most important developments of the last century. This process of integration, often called Globalization, has materialized in a remarkable growth in trade between countries. The chart here shows the value of world exports over the period These estimates are in constant prices i. 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 This will help you see that, over the long run, growth has roughly followed an exponential path.
The chart above shows how much more trade we have today relative to a century ago. But what about trade relative to total economic output? Over the last couple of centuries the world economy has experienced sustained positive economic growth , so looking at changes in trade relative to GDP offers another interesting perspective.
The next chart plots the value of trade in goods relative to GDP i. This shows that over the last hundred years of economic growth, there has been more than proportional growth in global trade. This creates an intricate network of economic interactions that cover the whole world.
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. It plots the position of cargo ships across the oceans. Over the last couple of centuries the world economy has experienced sustained positive economic growth , and over the same period, this process of economic growth has been accompanied by even faster growth in global trade.
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. This basic correlation is shown in the chart here, where we 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. 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.
Are these mechanisms supported by the data? When it comes to academic studies estimating the impact of trade on GDP growth, the most cited paper is Frankel and Romer In this study, Frankel and Romer used geography as a proxy for trade, in order to estimate the impact of trade on growth. This is a classic example of the so-called instrumental variable approach.
Following this logic, Frankel and Romer find evidence of a strong impact of trade on economic growth. Other papers have applied the same approach to richer cross-country data, and they have found similar results. 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. 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.
There is evidence suggesting this is often the case. Pavcnik examined the effects of liberalized trade on plant productivity in the case of Chile, during the late s and early s. She found a positive impact on firm productivity in the import-competing sector.
And she also found evidence of aggregate productivity improvements from the reshuffling of resources and output from less to more efficient producers. Bloom, Draca and Van Reenen examined the impact of rising Chinese import competition on European firms over the period , and obtained similar results.
They found that innovation increased more in those firms most affected by Chinese imports. 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.
On the whole, the available evidence suggests trade liberalization does improve economic efficiency. This evidence comes from different political and economic contexts, and includes both micro and macro measures of efficiency.
This result is important, because it shows that there are gains from trade. But of course efficiency is not the only relevant consideration here. As we discuss in a companion blog post , the efficiency gains from trade are not generally equally shared by everyone.
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. When a country opens up to trade, the demand and supply of goods and services in the economy shift. As a consequence, local markets respond, and prices change. This has an impact on households, both as consumers and as wage earners.
The implication is that trade has an impact on everyone. The effect of trade extends to everyone because markets are interlinked, so imports and exports have knock-on effects on all prices in the economy, including those in non-traded sectors.
The distribution of the gains from trade depends on what different groups of people consume, and which types of jobs they have, or could have. You can read more about these economic concepts, and the related predictions from economic theory, in Chapter 18 of the textbook The Economy: Economics for a Changing World.
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.
Additionally, they found that claims for unemployment and healthcare benefits also increased in more trade-exposed labor markets. The visualization here is one of the key charts from their paper. 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 trend line in this chart shows a negative relationship: more exposure goes together with less employment. 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.
This result is important because it shows that the labor market adjustments were large. Many workers and communities were affected over a long period of time. In particular, comparing changes in employment at the regional level misses the fact that firms operate in multiple regions and industries at the same time.
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.
This means that job losses in some regions subsidized new jobs in other parts of the country. On the whole, Magyari finds that although Chinese imports may have reduced employment within some establishments, these losses were more than offset by gains in employment within the same firms in other places. This is no consolation to people who lost their job. She finds that rural regions that were more exposed to liberalization, experienced a slower decline in poverty, and had lower consumption growth.
In the analysis of the mechanisms underlying this effect, Topalova finds that liberalization had a stronger negative impact among the least geographically mobile at the bottom of the income distribution, and in places where labor laws deterred workers from reallocating across sectors. 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.
This is because, while trade affects wages and employment, it also affects the prices of consumption goods. So households are affected both as consumers and as wage earners.
Most studies focus on the earnings channel, and try to approximate the impact of trade on welfare by looking at how much wages can buy, using as reference the changing prices of a fixed basket of goods. 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.
Ideally, studies looking at the impact of trade on household welfare should rely on fine-grained data on prices, consumption and earnings. Atkin and coauthors use a uniquely rich dataset from Mexico, and find that the arrival of global retail chains led to reductions in the incomes of traditional retail sector workers, but had little impact on average municipality-level incomes or employment; and led to lower costs of living for both rich and poor households.
The chart here shows the estimated distribution of total welfare gains across the household income distribution the light-gray lines correspond to confidence intervals. These are proportional gains, and are expressed as percent of initial household income. 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.
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. The available evidence shows that, for some groups of people, trade has a negative effect on wages and employment opportunities; and at the same time it has a large positive effect via lower consumer prices and increased availability of products. For some households, the net effect is positive. In particular, workers who lose their job can be affected for extended periods of time, so the positive effect via lower prices is not enough to compensate them for the reduction in earnings.
On the whole, if we aggregate changes in welfare across households, the net effect is usually positive. But this is hardly a consolation for those who are worse off. This highlights a complex reality: There are aggregate gains from trade , but there are also real distributional concerns.
The following visualization presents a compilation of available trade estimates, showing the evolution of world exports and imports as a share of global economic output. The higher the index, the higher the influence of trade transactions on global economic activity. The first wave of globalization came to an end with the beginning of the First World War, when the decline of liberalism and the rise of nationalism led to a slump in international trade.
In the chart we see a large drop in the interwar period. After the Second World War trade started growing again. This new — and ongoing — wave of globalization has seen international trade grow faster than ever before.
Klasing and Milionis , which is one of the sources in the chart, published an additional set of estimates under an alternative specification. You find all these alternative overlapping sources in this comparison chart. Over the early modern period, transoceanic flows of goods between empires and colonies accounted for an important part of international trade.
The following visualizations provides a comparison of intercontinental trade, in per capita terms, for different countries. As we can see, intercontinental trade was very dynamic, with volumes varying considerably across time and from empire to empire.
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. The following visualization shows a detailed overview of Western European exports by destination. Figures correspond to export-to-GDP ratios i.
But this process of European integration then collapsed sharply in the interwar period. After the Second World War trade within Europe rebounded, and from the s onwards exceeded the highest levels of the first wave of globalization.
In addition Western Europe then started to increasingly trade with Asia, the Americas, and to a smaller extent Africa and Oceania. The indicators in this chart are indexed, so they show changes relative to the levels of integration observed in This gives us another viewpoint to understand how quickly global integration collapsed with the two World Wars.
