Adam Smith and David Ricardo gave the classical theories of international trade. According to their theories, when a country enters in an overseas trade, it gains advantages of specialisation and efficient useful resource allocation. This is because overseas trade brings in new technology and abilities that lead to better productivity.
The assumptions taken in the classical theory are as follows:
- There are nations producing two goods. The size of economies of those nations is equal.
- There is perfect mobility of inputs for manufacturing inside nations.
- Transportation value is ignored.
- Before specialisation, a country’s assets are equally divided to provide every good.

Classical Trade Theories
The classical theories are divided into three theories:
Theory of Mercantilism
‘Mercantilism’ is the term that became popular after it was used by Adam Smith, the Father of Economics, in his book, “The Wealth of Nations”. Western European economic regulations have substantially ruled through this theory. The idea of mercantilism holds that nations need to inspire export and discourage import.
The earliest causes of global business emerged with the rise of European states in the 1500s, when gold and silver were the crucial sources of wealth, and countries sought to accumulate as a great deal of those treasures, in particular gold, as possible.
According to this theory, authorities need to play a crucial function within the economic system by encouraging export and discouraging import through the use of subsidies and taxes, respectively. In those days, gold was used for trading items among international nations.
In essence, mercantilism explains why countries try to run a trade surplus—that is, to export more items than they import. Even nowadays many people trust that running a trade surplus is beneficial. On the other hand, mercantilism has a tendency to harm the interests of companies that import, specifically people who import raw materials and components.
Mercantilism additionally harms the interests of consumers; due to the fact limiting imports reduces the choice of merchandise they could buy. Product shortages that result from import regulations may also cause better prices—that is inflation. When taken to an extreme, mercantilism may also invite “beggar thy neighbour” policies, promoting the advantages of one country on the price of others. Mercantilism also known as zero-sum theory as just one country benefitted from it.
Theory of Absolute Advantage
The theory of absolute advantage said that a country needs to concentrate on those products, which it may produce efficiently. This theory assumes that there’s only one factor of manufacturing which is important, i.e., labour+. Relative to others, each country is more efficient with the manufacturing of one or few merchandise and much less efficient with the manufacturing of different products.
Smith’s absolute advantage principle states that a country gains an advantage by generating basically the products that generate an absolute advantage or those that are produced using fewer sources than another country. The principle states that any country can be more efficient in producing a certain kind of product in comparison to other countries. This theory is subjective in nature.
Each country for that reason will increase its welfare by specialising in the manufacturing of certain products, exporting them and uploading others. This approach permits the country to consume extra than it otherwise could, usually at lower price. Adam Smith said that under mercantilism, it was not possible for countries to emerge as wealthy simultaneously. He also said that wealth of the countries does now no longer depend on the gold reserves, however upon the products and services available to their citizens.
Adam Smith wrote in his book The Wealth of Nations “if an overseas country can deliver us with a commodity less expensive than we ourselves can make it, higher purchase of them with some part of the produce of our own industry, employed in a way in which we’ve got a few advantage”. He said that trade might be useful for both the international locations if country A exports the goods, which it is able to produce with decrease price than country B and import the goods, which country B can produce with lower price than it.
Each country benefits by specialising in producing the product in which it has an absolute benefit and securing the other product via trade. Each then employs its labour and different resources with most performance and, as a result, will increase its standard of living. While the concept of absolute advantage supplied possibly the earliest sound purpose for international trade, it accounted most effective for the absolute advantages possessed by nations and didn’t consider greater diffused blessings they may enjoy.
Later studies found out that a country advantages from global trade even if it lacks an absolute advantage. This line of questioning led to the principle of comparative advantage. Therefore, the theory of absolute advantages suggests that trade might be beneficial for both the countries.
Theory of Comparative Advantage
In his book ‘The Principles of Political Economy and Taxation’, British political economist David Ricardo described why it’s a way useful for two countries to exchange even though one of them may have absolute benefit with the production of all products. Ricardo confirmed that what matters isn’t absolutely the cost of production, however instead the relative efficiency with which the two nations can produce the products.
Hence, the comparative benefit precept states that it is able to be useful for two international countries to trade without obstacles so long as one is relatively greater efficient at producing goods or services wanted by the other.
The principle of comparative benefit is the foundation and overriding justification for global trade. The comparative advantage view is constructive as it means that a nation may no longer be the first-, second-, or may be third-best manufacturer of unique products to benefit from global exchange. Indeed, it is far commonly effective for all international locations to take part in global exchange.
While a nation may conceivably have a sufficient sort of manufacturing elements to provide each type of product and service, it can’t produce every product with the same facility. This idea assumes that labour because the most effective component of manufacturing in countries, zero delivery cost, and no trade obstacles in the countries.
A comparative benefit happens when a country can’t produce a product more correctly than the other country; however, it is able to produce that product higher and more efficiently than it does different goods. The difference among those theories is subtle. A comparative advantage specialises in the relative productivity differences, whereas absolute benefit seems on the absolute productivity.
Heckscher and Ohlin Theory— Modern Theory of International Trade
In the early 1900s, Swedish economists, Eli Heckscher and Bertil Ohlin centred their interest on how a country may want to benefit a competitive advantage by generating products that applied elements that have been in abundance in the country. Their principle is primarily based totally on a country’s production elements which are land, labourand capital, which give the budget for funding in plants and equipment. They decided that the price of anything or resource become a characteristic of deliver and demand.
Factors that have been in great supply relative to demand could be less expensive; factors in great demand relative to deliver could be more expensive. Their concept, also referred to as the factor proportions theory, stated that countries could produce and export goods that required assets or elements that have been in great supply and, therefore, less expensive manufacturing factors.
In contrast, nations could import items that required assets that have been in quick supply, however higher demand. For example, the U.S. produces and exports capital-intensive products, inclusive of pharmaceuticals and industrial aircraft, at the same time as Argentina produces land-intensive products, inclusive of wine and sunflower seeds. This theory describes how abundant production factors give rise to national advantages.
The factor proportion theory differs relatively from earlier theories through emphasising the significance of every nation’s factors of manufacturing. The theory states that, further to differences in the efficiency of manufacturing, differences in the quantity of factors of manufacturing held through nations additionally decide global trade patterns. This leads to a per-unit-cost advantage because of the abundance of a given factor of production, say labour, over another, say land, which isn’t in as much supply. Originally, labour turned into the most critical element of manufacturing.
This theory classifies goods into two kinds, such as Labour intensive and capital intensive. A labour rich country can concentrate in producing labour intensive goods while capital rich country can concentrate in capital intensive goods.
The assumptions of the Heckscher and Ohlin theory are as follows:
- Needs of residents of the two nations are same.
- Transportation price among the nations is zero.
- Factors of manufacturing in both the nations are immobile.
- Factors of manufacturing in both the nations are not available in same proportion.
Leontief Paradox
The Leontief paradox is one of the most famous and critical contradictions in the history of economics. In one of the most generally mentioned tests of the component proportions theory, Leontief tried to reveal the relative component proportions structure of U.S. participation in world trade. The thought behind ‘The Leontief paradox’ was that a country can tend to export those commodities that use its abundant parts of producing intensively and import those which use its scarce issue intensively.
The United States has abundant capital; it needs to be an exporter of capital-in depth products. However, Leontief’s analysis, termed the Leontief paradox, found out that America regularly exported labour-intensive items and imported extra capital-in depth items than the concept might typically predict.
The H-O theory surely states that a country with a labour-in depth financial system will export goods produced by it, while a country that’s considerable in capital will export capital produced items. Leontief argued that American labour could not truly be as in comparison to labour in other international locations, due to the fact the productiveness of an American employee is substantially higher (3 instances higher, counselled Leontief) than that of foreign workers.
Another cause of which Leontief has proven certain information is attached with the two component framework and the broad use of the term capital. The handiest elements explicitly taken into consideration are labour and capital. Leontief quickly attempted to resolve his personal paradox by arguing that, the productiveness of the labour with inside the United States changed into far greater than as in comparison to the countries it changed into getting its imports from.
Thus, if the labour input of the country had been adjusted via way of means of a component of three, then America could simply grow to be a labour abundant country. Despite those suggestions, economists persevered to maintain the validity of the paradox.
New Trade Theory
In the beginning of the 1970s, economists led by Paul Krugman found that trade was developing quickly among industrialised nations with comparable factors of manufacturing. In a few new industries, there appeared to be no clean comparative advantage. The approach to this puzzle is referred to as the new trade theory. It argues that increasing returns to scale, in particular economies of scale, are important for advanced worldwide performance in industries that succeed high-quality as their production extent increases.
For example, an industrial aircraft enterprise has excessive fixed costs that necessitate high-extent income to acquire profitability. As a nation specialises in the manufacturing of such goods, productivity increases, and unit costs fall, offering enormous advantages to the local economy.
However, many countrywide markets are small, and the domestic producer might not achieve economies of scale as it cannot promote products in big extent. The new trade theory means that companies can resolve this trouble by exporting, thereby getting access to the large international marketplace.
Several industries acquire minimally profitable economies of scale by promoting their output in multiple markets worldwide. The effect of growing returns to scale allows the state to focus on a smaller quantity of industries wherein it may now no longer always hold thing or comparative advantages.
Countries do not always trade best to gain from their differences; however, they also trade to growth their returns, which in flip permit them to gain from specialisation. International change permits a company to increase its output because of its specialisation through providing a far large market those consequences in enhancing its efficiency.
Since fixed costs are shared over an improved output, the economy of scale permits a company to reduce its per unit average cost of manufacturing and enhances its price competitiveness. This theory brings the idea of economies of scale to explicate the Leontief paradox.
Let us study two types of economies of scale:
- Internal economies of scale: Companies gain by the economies of scale when the price per unit of output relies upon their size. The large the size, the better are the economies of scale. Firms that enhance their internal economies of scale can decrease their price and monopolise the industry, growing imperfect market competition. This in turn leads to reduced market charges due to imperfect market competition.
Internal economies of scale may lead a firm to specialise in a narrow product line to provide the extent necessary to reap price benefits from scale economies. Internal economies of scale may lead a corporation to specialise in a slim product line to supply the extent necessary to achieve price advantages from scale economies. - External economies of scale: If the cost per unit of output relies upon the scale of the industry, not upon the scale of an individual firm, it is called external economies of scale. This allows the enterprise in a country to produce at a decrease rate while the enterprise size is massive as compared to the same enterprise in a foreign country with a particularly smaller enterprise size.
The dominance of a particular country with the international market in a specific products region with higher external economies of scale is attributed to the massive size of a country’s industry that has several small firms, which interact to create a large, aggressive crucial mass in place of a large-sized individual firm.
The higher economies of scale lead to growth in returns and allow nations to specialise in the manufacturing of such goods and trade with nations having similar consumption patterns. Besides intra-industry trade, the idea additionally explains intrafirm exchange among the MNEs and their subsidiaries, with a reason to take benefit of the scale economies and increase their return.
Porter’s Diamond Theory of National Advantage
Micheal Porter gave the diamond theory of national advantage, which states that the functions of domestic country are critical for the success of an organisation in global markets. It describes the elements that make a contribution to the success of organisations in international industries. These elements are known as the determinants of the national advantage.
The following are the elements of the theory:
Firm strategy, structure and rivalry
The diamond theory states that the nature of domestic contention and situations in a nation decide how companies are created, organised, and managed. The presence of strong competition in a state helps to create and keep national aggressive advantage.
Japan has the world’s most aggressive purchaser electronics enterprise, with major players like Nintendo, NEC, Sharp and Sony generating semiconductors, computers, video games and liquid crystal displays. Vigorous competitive contention places those companies beneath continual stress to innovate and improve.
They compete now no longer simplest for market share, however additionally for human talent, technical leadership, and superior product quality. Intense rivalry has driven firms like Sony to a main role in the enterprise global and allowed Japan to become the top country in customer electronics.
Factor conditions
These include elements of production, such as labour, natural resources, capital, technology, entrepreneurship, and know-how. Consistent with aspect proportions theory, every country has a relative abundance of certain factor endowments, a situation that allows deciding the nature of its national aggressive advantage.
Demand conditions
The power and sophistication of purchaser demand helps the improvement of competitive benefits especially industries. The presence of highly demanding customer pressure corporations to innovate quicker and convey higher products.
For example, an affluent, growing older population in the United States stimulated the improvement of world-elegance fitness care corporations such as Pfizer and Eli Lilly in prescribed drugs and Boston Scientific and Medtronic in medical equipment.
