International trade
Encyclopedia
International trade is the exchange of capital
, goods, and services across international borders or territories. In most countries, such trade represents a significant share of gross domestic product
(GDP). While international trade
has been present throughout much of history (see Silk Road
, Amber Road
), its economic, social, and political importance has been on the rise in recent centuries.
Industrialization, advanced transport
ation, globalization
, multinational corporation
s, and outsourcing
are all having a major impact on the international trade system. Increasing international trade is crucial to the continuance of globalization
. Without international trade, nations would be limited to the goods and services produced within their own borders.
International trade is, in principle, not different from domestic trade
as the motivation and the behavior of parties involved in a trade do not change fundamentally regardless of whether trade is across a border or not. The main difference is that international trade is typically more costly than domestic trade. The reason is that a border typically imposes additional costs such as tariff
s, time costs due to border delays and costs associated with country differences such as language, the legal system or culture.
Another difference between domestic and international trade is that factors of production
such as capital and labor are typically more mobile within a country than across countries. Thus international trade is mostly restricted to trade in goods and services, and only to a lesser extent to trade in capital, labor or other factors of production. Trade in goods and services can serve as a substitute for trade in factors of production.
Instead of importing a factor of production, a country can import goods that make intensive use of that factor of production and thus embody it. An example is the import of labor-intensive goods by the United States from China. Instead of importing Chinese labor, the United States imports goods that were produced with Chinese labor. One report in 2010 suggested that international trade was increased when a country hosted a network of immigrants, but the trade effect was weakened when the immigrants became assimilated into their new country.
International trade is also a branch of economics
, which, together with international finance
, forms the larger branch of international economics

such as tariff
s.
, perhaps the most important concept in international trade theory. In a Ricardian model, countries specialize in producing what they produce best, and trade occurs due to technological differences between countries. Unlike other models, the Ricardian framework predicts that countries will fully specialize instead of producing a broad array of goods.
Also, the Ricardian model does not directly consider factor endowment
s, such as the relative amounts of labor and capital within a country. The main merit of Ricardian model is that it assumes technological differences between countries. Technological gap is easily included in the Ricardian and Ricardo-Sraffa model (See the Ricardian theory (modern development)).
The Ricardian model makes the following assumptions:
The Ricardian model applies in the short run, so that technology may vary internationally. This supports the fact that countries follow their comparative advantage and allows for specialization.
For the modern development of Ricardian model, see the subsection below: Ricardian theory of international trade.
and Bertil Ohlin
. This theory is therefore called the Heckscher-Ohlin theory (H-O theory). The H-O theory stresses that countries should produce and export goods that require resources (factors) that are abundant and import goods that require resources in short supply. It differs from the theories of comparative advantage and absolute advantage since those theories focus on the productivity of the production process for a particular good. On the contrary, the Heckscher-Ohlin theory states that a country should specialize in producing and exporting products that use the factors that are most abundant, and thus are the cheapest to produce.
The Heckscher-Ohlin model was produced as an alternative to the Ricardian model of basic comparative advantage. Despite its greater complexity it did not prove much more accurate in its predictions. However from a theoretical point of view it did provide an elegant method of incorporating the neoclassical price mechanism into international trade theory.
The theory argues that the pattern of international trade is determined by differences in factor endowments. It predicts that countries will export
those goods that make intensive use of locally abundant factors and will import goods that make intensive use of factors that are locally scarce. Empirical problems with the H-O model, such as the Leontief paradox
, were exposed in empirical tests by Wassily Leontief
who found that the United States tended to export labor-intensive goods despite having an abundance of capital.
The H-O model makes the following core assumptions:
The problem with the H-O theory is that it excludes the trade of capital goods (including materials and fuels). In the H-O theory, labor and capital are fixed entities endowed to each country. In a modern economy, capital goods are traded internationally. Gains from trade of intermediate goods are considerable, as emphasized by Samuelson (2001).
After the appearance of Leontief's paradox, many researchers tried to save the Heckscher-Ohlin theory, either by new methods of measurement, or either by new interpretations. Leamer emphasized that Leontief did not interpret H-O theory properly and claimed that with a right interpretation, the paradox did not occur. Brecher and Choudri found that, if Leamer was right, the American workers' consumption per head should be lower than the workers' world average consumption.
Many other trials followed but most of them failed. Many textbook writers, including Krugman and Obstfeld and Bowen, Hollander and Viane, are negative about the validity of H-O model. After examining the long history of empirical research, Bowen, Hollander and Viane concluded: "Recent tests of the factor abundance theory [H-O theory and its developed form into many-commodity and many-factor case] that directly examine the H-O-V equations also indicate the rejection of the theory."
Heckscher-Ohlin theory is not well adapted to the analyze South-North trade problems. The assumptions of H-O are less realistic with respect to N-S than N-N (or S-S) trade. Income differences between North and South is the assumption that third world cares about most. There is not much evidence of factor price equalization [a consequence of H-O theory. The H-O model assumes identical production functions among countries, although this is highly unrealistic. Technological gaps between developed and developing countries are the main reason why the latter are poor.
Additionally, owners of opposing specific factors of production (i.e., labor and capital) are likely to have opposing agendas when lobbying for controls over immigration of labor. Conversely, both owners of capital and labor profit in real terms from an increase in the capital endowment. This model is ideal for understanding income distribution but awkward for discussing the pattern of trade.
and increasing returns to scale
. One result of these theories is the home-market effect
, which asserts that, if an industry tends to cluster in one location because of returns to scale and if that industry faces high transportation costs, the industry will be located in the country with most of its demand, in order to minimize cost.
which also considers distance and physical size between two objects. The model has been proven to be empirically strong through econometric analysis.
This model has been expanded to many-country and many-commodity cases. Major general results were obtained by McKenzie and Jones, including his famous formula. It is a theorem about the possible trade pattern for N-country N-commodity cases.
theories uses a special property that is applicable only for the two-country case.
, a new strand of trade theory emerged and was named neo-Ricardian trade theory. The main contributors include Ian Steedman (1941-) and Stanley Metcalfe (1946-). They have criticized neoclassical international trade theory, namely the Heckscher-Ohlin model
on the basis that the notion of capital as primary factor has no method of measuring it before the determination of profit rate (thus trapped in a logical vicious circle). This was a second round of the Cambridge capital controversy
, this time in the field of international trade.
The merit of neo-Ricardian trade theory is that input goods are explicitly included. This is in accordance with Sraffa's idea that any commodity is a product made by means of commodities. The limitation of their theory is that the analysis is restricted to small-country cases.
McKenzie and Jones emphasized the necessity to expand the Ricardian theory to the cases of traded inputs. In a famous comment McKenzie (1954, p. 179) pointed that "A moment's consideration will convince one that Lancashire would be unlikely to produce cotton cloth if the cotton had to be grown in England."
Paul Samuelson
coined a term Sraffa bonus to name the gains from trade of inputs.
observed in his survey that McKenzie stumbled upon the questions of intermediate products and discovered that "introduction of trade in intermediate product necessitates a fundamental alteration in classical analysis." It took many years until Y. Shiozawa succeeded in removing this deficiency. The Ricardian trade theory was now constructed in a form to include intermediate input trade for the most general case of many countries and many goods. This new theory is called Ricardo-Sraffa trade theory.
The Ricardian trade theory now provides a general theory that includes trade of intermediates such as fuel, machine tools, machinery parts and processed materials. The traded intermediate goods are then used as inputs to production in the importing country. Capital goods are nothing other than inputs to the production. Thus, in the Ricardo-Sraffa trade theory, capital goods move freely from country to country. Labor is the unique factor of production that remains immobile in its country of origin.
In a blog post of April 28, 2007, Gregory Mankiw compared Ricardian theory and Heckscher-Ohlin
theory and stood by the Ricardian side. Mankiw argued that Ricardian theory is more realistic than the Heckscher-Ohlin theory as the latter assumes that capital does not move from country to country. Mankiw's argument contains a logical slip, for the traditional Ricardian trade theory does not admit any inputs. Shiozawa's result saves Mankiw from his slip.
The neoclassical Heckscher-Ohlin-Samuelson theory only assumes productive factors and finished goods. It has no concept of intermediate goods. Therefore, it is the Ricardo-Sraffa trade theory that provides theoretical bases for ideas such as outsourcing, fragmentation and intra-firm trade.

most nations had high tariff
s and many restrictions on international trade. In the 19th century, especially in the United Kingdom
, a belief in free trade
became paramount. This belief became the dominant thinking among western nations since then. In the years since the Second World War, controversial multilateral treaties like the General Agreement on Tariffs and Trade
(GATT) and World Trade Organization
have attempted to promote free trade
while creating a globally regulated trade structure. These trade agreements have often resulted in discontent and protest with claims of unfair trade that is not beneficial to developing countries.
Free trade is usually most strongly supported by the most economically powerful nations, though they often engage in selective protectionism
for those industries which are strategically important such as the protective tariffs applied to agriculture by the United States
and Europe
. The Netherlands
and the United Kingdom were both strong advocates of free trade when they were economically dominant, today the United States, the United Kingdom, Australia
and Japan
are its greatest proponents. However, many other countries (such as India, China and Russia) are increasingly becoming advocates of free trade as they become more economically powerful themselves. As tariff levels fall there is also an increasing willingness to negotiate non tariff measures, including foreign direct investment, procurement and trade facilitation
. The latter looks at the transaction cost
associated with meeting trade and customs
procedures.
Traditionally agricultural interests are usually in favour of free trade while manufacturing sectors often support protectionism. This has changed somewhat in recent years, however. In fact, agricultural lobbies, particularly in the United States, Europe and Japan, are chiefly responsible for particular rules in the major international trade treaties which allow for more protectionist measures in agriculture than for most other goods and services.
During recession
s there is often strong domestic pressure to increase tariffs to protect domestic industries. This occurred around the world during the Great Depression
. Many economists have attempted to portray tariffs as the underlining reason behind the collapse in world trade that many believe seriously deepened the depression.
The regulation of international trade is done through the World Trade Organization at the global level, and through several other regional arrangements such as MERCOSUR
in South America, the North American Free Trade Agreement
(NAFTA) between the United States, Canada and Mexico, and the European Union
between 27 independent states. The 2005 Buenos Aires talks on the planned establishment of the Free Trade Area of the Americas
(FTAA) failed largely because of opposition from the populations of Latin American nations. Similar agreements such as the Multilateral Agreement on Investment
(MAI) have also failed in recent years.
In addition, international trade also faces the risk of unfavorable exchange rate movements (and, the potential benefit of favorable movements).

The definitions and methdological concepts applied for the various statistical collections on international trade often differ in terms of definition (e.g. special trade vs. general trade) and coverage (reporting thresholds, inclusion of trade in services, estimates for smuggled goods and cross-border provision of illegal services).

The Ricardian model makes the following assumptions:
- Labor is the only primary input to production (labor is considered to be the ultimate source of value).
- Constant Marginal Product of Labor (MPL) (Labor productivity is constant, constant returns to scale, and simple technology.)
- Limited amount of labor in the economy
- Labor is perfectly mobile among sectors but not internationally.
- Perfect competition (price-takers).
The Ricardian model applies in the short run, so that technology may vary internationally. This supports the fact that countries follow their comparative advantage and allows for specialization.

In a modern economy, capital goods are traded internationally. Gains from trade of intermediate goods are considerable, as emphasized by Samuelson (2001).
Reality and Applicability of the Heckscher-Ohlin Model
Many economists prefer the Heckscher-Ohlin theory to the Ricardian theory, because H-O makes fewer simplifying assumptions. In 1953, Wassily Leontief published a study in which he tested the validity of the Heckscher-Ohlin theory. The study showed that the U.S was more abundant in capital compared to other countries, therefore the U.S would export capital-intensive goods and import labor-intensive goods. Leontief found out that the U.S's exports were less capital intensive than its imports.After the appearance of Leontief's paradox, many researchers tried to save the Heckscher-Ohlin theory, either by new methods of measurement, or either by new interpretations. Leamer emphasized that Leontief did not interpret H-O theory properly and claimed that with a right interpretation, the paradox did not occur. Brecher and Choudri found that, if Leamer was right, the American workers' consumption per head should be lower than the workers' world average consumption.
Many other trials followed but most of them failed. Many textbook writers, including Krugman and Obstfeld and Bowen, Hollander and Viane, are negative about the validity of H-O model. After examining the long history of empirical research, Bowen, Hollander and Viane concluded: "Recent tests of the factor abundance theory [H-O theory and its developed form into many-commodity and many-factor case] that directly examine the H-O-V equations also indicate the rejection of the theory."
Heckscher-Ohlin theory is not well adapted to the analyze South-North trade problems. The assumptions of H-O are less realistic with respect to N-S than N-N (or S-S) trade. Income differences between North and South is the assumption that third world cares about most. There is not much evidence of factor price equalization [a consequence of H-O theory. The H-O model assumes identical production functions among countries, although this is highly unrealistic. Technological gaps between developed and developing countries are the main reason why the latter are poor.
Specific factors model
In the specific factors model, labor mobility among industries is possible while capital is assumed to be immobile in the short run. Thus, this model can be interpreted as a short-run version of the Heckscher-Ohlin model. The "specific factors" name refers to the assumption that in the short run, specific factors of production such as physical capital are not easily transferable between industries. The theory suggests that if there is an increase in the price of a good, the owners of the factor of production specific to that good will profit in real terms.Additionally, owners of opposing specific factors of production (i.e., labor and capital) are likely to have opposing agendas when lobbying for controls over immigration of labor. Conversely, both owners of capital and labor profit in real terms from an increase in the capital endowment. This model is ideal for understanding income distribution but awkward for discussing the pattern of trade.
New Trade Theory
New Trade Theory tries to explain empirical elements of trade that comparative advantage-based models above have difficulty with. These include the fact that most trade is between countries with similar factor endowment and productivity levels, and the large amount of multinational production (i.e. foreign direct investment) that exists. New Trade theories are often based on assumptions such as monopolistic competitionMonopolistic competition

, which asserts that, if an industry tends to cluster in one location because of returns to scale and if that industry faces high transportation costs, the industry will be located in the country with most of its demand, in order to minimize cost.

The Gravity model of trade presents a more empirical analysis of trading patterns. The gravity model, in its basic form, predicts trade based on the distance between countries and the interaction of the countries' economic sizes. The model mimics the Newtonian law of gravityLaw of Gravity

which also considers distance and physical size between two objects. The model has been proven to be empirically strong through econometric analysis.
Ricardian theory of international trade (modern development)
The Ricardian theory of comparative advantage became a basic constituent of neoclassical trade theory. Any undergraduate course in trade theory includes a presentation of Ricardo's example of a two-commodity, two-country model.This model has been expanded to many-country and many-commodity cases. Major general results were obtained by McKenzie and Jones, including his famous formula. It is a theorem about the possible trade pattern for N-country N-commodity cases.
Contemporary theories
Ricardo's idea was even expanded to the case of continuum of goods by Dornbusch, Fischer, and Samuelson This formulation is employed for example by Matsuyama and others. Thesetheories uses a special property that is applicable only for the two-country case.

The merit of neo-Ricardian trade theory is that input goods are explicitly included. This is in accordance with Sraffa's idea that any commodity is a product made by means of commodities. The limitation of their theory is that the analysis is restricted to small-country cases.
Traded intermediate goods
Ricardian trade theory ordinarily assumes that the labor is the unique input. This is a great deficiency as trade theory, for intermediate goods occupy the major part of the world international trade. Yeats found that 30% of world trade in manufacturing involves intermediate inputs. Bardhan and Jafee found that intermediate inputs occupy 37 to 38% of U.S. imports for the years 1992 and 1997, whereas the percentage of intrafirm trade grew from 43% in 1992 to 52% in 1997.McKenzie and Jones emphasized the necessity to expand the Ricardian theory to the cases of traded inputs. In a famous comment McKenzie (1954, p. 179) pointed that "A moment's consideration will convince one that Lancashire would be unlikely to produce cotton cloth if the cotton had to be grown in England."

Traditionally agricultural interests are usually in favour of free trade while manufacturing sectors often support protectionism. This has changed somewhat in recent years, however. In fact, agricultural lobbies, particularly in the United States, Europe and Japan, are chiefly responsible for particular rules in the major international trade treaties which allow for more protectionist measures in agriculture than for most other goods and services.

Risk in international trade
Companies doing business across international borders face many of the same risks as would normally be evident in strictly domestic transactions. For example,- Buyer insolvency (purchaser cannot pay);
- Non-acceptance (buyer rejects goods as different from the agreed upon specifications);
- Credit risk (allowing the buyer to take possession of goods prior to payment);
- Regulatory risk (e.g., a change in rules that prevents the transaction);
- Intervention (governmental action to prevent a transaction being completed);
- Political risk (change in leadership interfering with transactions or prices); and
- War, piracy and civil unrest or turmoil;
- Natural catastrophes, freak weather and other uncontrollable and unpredictable events,
In addition, international trade also faces the risk of unfavorable exchange rate movements (and, the potential benefit of favorable movements).
