David Ricardo was a classical economist and one of the most influential figures in the development of modern economic theory. His contributions to the field of economics, particularly in the areas of international trade and comparative advantage, have had a lasting impact and continue to be studied and debated by economists today.
Ricardo's theory of international trade is based on the idea of comparative advantage, which holds that countries should specialize in producing the goods and services in which they have a comparative advantage and trade with other countries for the goods and services they do not produce. This theory is based on the premise that countries have different endowments of resources and therefore have different costs of production for different goods and services. By specializing in the production of those goods and services in which they have a comparative advantage, countries can increase their efficiency and maximize their economic output.
According to Ricardo, the concept of comparative advantage can be demonstrated through the use of an example involving two countries, England and Portugal, producing two goods, cloth and wine. Suppose that it takes 100 units of labor to produce a unit of cloth in England and 120 units of labor to produce a unit of cloth in Portugal. Similarly, it takes 90 units of labor to produce a unit of wine in England and 80 units of labor to produce a unit of wine in Portugal.
At first glance, it appears that Portugal has a comparative advantage in the production of wine because it requires fewer units of labor to produce a unit of wine than England. However, Ricardo's theory of comparative advantage suggests that England should specialize in the production of cloth and trade with Portugal for wine. This is because, even though it takes more units of labor to produce a unit of cloth in England than in Portugal, the opportunity cost of producing cloth in England is lower than in Portugal. This is because the opportunity cost of producing cloth in England is 1 unit of wine, while the opportunity cost of producing cloth in Portugal is 1.5 units of wine. Therefore, it is more efficient for England to specialize in the production of cloth and trade with Portugal for wine, while Portugal should specialize in the production of wine and trade with England for cloth.
Ricardo's theory of comparative advantage has been influential in shaping economic policy and trade negotiations around the world. It has also been the subject of much debate and criticism, with some arguing that it does not account for certain factors such as transportation costs and technological differences between countries. Despite these criticisms, the theory of comparative advantage remains an important foundation of modern international trade theory and continues to be a significant influence in economic policy decisions.
Ricardian trade theory
It should be noted that, to know the comparative advantage, we have to compare the ratio of the costs of production of one commodity in both countries i. However, all nations will not appreciate the need for them to trade with one another. In fact, the principle of comparative costs shows that it is possible for both the countries to gain from trade, even if one of them is more efficient than the other in all lines of production. This is so because there are a large number of goods and many countries. Since more consumption means greater satisfaction using economic jargon, equilibrium shifts to a higher indifference curve , trade allow both countries to improve their welfare.
Theory of Comparative Advantage of International Trade: by David Ricardo
But, the credit goes to David Ricardo in formulating an explicit and precise theory called "The Theory of Comparative Cost". Thus, while the proposition bears his name, he does not seem to have believed it. Equal Cost Difference According to Ricardo, if there is equal cost difference, it is not advantageous for trade and specialisation for any country in consideration Table 1. Ricardo developed his theory by comparing two countries, England and Portugal, and two commodities, wine and cloth. In his free time, he began developing the modern theory of international trade.
What are the reasons for international trade? Hence, when there are increasing costs, specialisation will not be as complete, nor the volume of trade as large, as is the case when costs are constant. If, however, there is an equal cost difference, i. Similarly, another country would produce those goods say, machineries and engineering goods as in GerÂmany or Japan in which it has comparative advantage. In our illustration, since country A has comparative cost advantage in commodity X, as per Ricardo s theorem, this country should tend to specialise in X and export its surplus to country Ð’ in exchange for У i. Trade is viewed by many as being important for poverty reduction in developing countries and …show more content… Ricardo identified two additional sources of growth in addition to capital and these being technical innovation and international trade. The classical theory of international trade was first developed by Adam Smith in his book "The Wealth of Nations" published in 1776.
There can be both winners and losers from trade, but generally, the winners gain more than the losers lose. It was developed by Bertil Ohlin and Eli Heckscher. Absolute advantage is a specific example of the advantages of specialÂisation and division of labour. Coming from the assumption of Ricardian Model, the labour is fixed and not crosses to the other country. For example, the writer ignores the use of facts by assuming that the 30% improvement in production in the US was achieved in all sectors of the economy. America produces motor cars. This theory presented two countries are endowed with different level or degree of the production factors, and the naturally determined endowments, country would follow the endowments to trade the comparative advantage goods to the other one.
He underlined the principle of absolute advantage as the theory of international trade. Canada is good at producing apples, and produces more apples than bananas. Even though Portugal has an Because of this advantage, both countries would benefit from international trade. Equal Cost Difference : Ricardo argues that if there is equal cost difference, it is not advantageous for trade and specialisation for any country in consideration see Table 2. Portugal would produce only wine, consuming C w and exporting X w to England, while England would produce only cloth, consuming C c and exporting X c to Portugal. In country A, domestic exchange ratio between X and Y is 12 : 10, i. Second, it will provide an example of Kazakhstan and Russia for more explanation.
Malthus appears to think that it is a part of my doctrine, that the cost and value of a thing be the same;—it is, if he means by cost, "cost of production" including profit. He used the 1937 data; those data showed US wage rate is double to UK wage rate.

International trade has became an integral part of each andevery economy of the world. In algebraic terms, let labour cost of producing X-commodity in country A is a 1 and in country B is a 2. The Ricardian Model really proved UK free international trade in grains.
Although it increases the net productivity of the countries involved in the trade, it can also increase the inequalities among the countries. Now, if after trade, assuming the terms of trade to be IX — 1Y, country A gains 0. Indeed, the relative gains of the two countries will be conditioned by the terms of trade and one is likely to gain proportionately more than the other but it is definite that both will gain. This would strengthen the case for international exchange of goods. Hence, every country got varies productivity or technology; the endowments were the factor of their relative the productivity. Stable institutions are detrimental to the success of the economy because they provide a sense of security for investing. The Legacy of Ricardo.
Ricardo notes that the proposition is theoretically implied in the presence of intertemporal optimisation by rational tax-payers: but that since tax-payers do not act so rationally, the proposition fails to be true in practice. Journal of Economic Perspectives. Later on, he left the Netherlands and stopped contacting his family in order to avoid an arranged marriage. Therefore, the La is fixed, we keep the La constant. European Journal of the History of Economic Thought. Works and Correspondence of David Ricardo, Volume I, Cambridge University Press, 1951, p.
Summary Comparative advantage is an important aspect of economics, and it has made many economists design studies aimed at understanding the concept in a better manner. This is a dangerous assumption that could lead to inaccurate projections in the future because economists focus on past events to predict economic performances in the future. What are the important basis of international trade? Hence, there is no comparative advantage between country a and b the absolute advantage country got same rate in both goods with the absolute disadvantage country , which means, there is equal disadvantage and equal advantage. Despite the fact that a Ricardian model is a simple approach with regard to international free trade, distinguished economists have argued that the approach to trade looks oversimplified. Labour is homogeneous i. This clause is one of the most fundamental powers delegated to congress by the founders. On the Principles of Political Economy and Taxation.
David Ricardo’s Theory of Comparative Cost Advantage
Different countries had differences in productivity and technology. The Basics David Ricardo was one of the most influential economists of the early nineteenth century. In fact, the people who often term the model simple are casual readers who have no deep interest in understanding the impact of the aspect of international trade. The fun light-hearted analogies are also a welcome break to some very dry content. I have been using the videos to prepare for the CFA Level II exam.
