Thus, with increases U.S.A. specialising in the production of wheat and India in cloth, through reallocation of labour between wheat and cloth, the total production will increase. In India one kg. When the U.S.A. and India specialise in wheat and cloth respectively and trade takes place between them, the U.S.A. will gain if it has to give less than can get more than 0.5 units of cloth from India for one unit of wheat and India will gain if it 1.33 units of cloth to the U.S.A. for import of one unit of wheat. This can be shown by superimposing the opportunity cost curve CD of India over the opportunity cost of U.S.A., in such a way that point D is joined with point B of U.S.A. Let us make in-depth study of the critical appraisal and factors for the variation of comparative cost theory of international trade. This is because, he argued that given the same technological development, the proportions in which other factors could be combined with labour would be the same. (i) According to the classical economists, there was need for a separate theory of international trade because international trade was fundamently different from internal trade. Likewise, 80 metres of cloth in U.S.A. has the opportunity cost of 60 kg. The opportunity cost of a commodity, say wheat, is amount of another commodity, say cloth, which a country has to give up to produce an additional unit of wheat. It will be much better if after comparing the costs of the various goods which it can produce it selects those in which the comparative costs are lower or in which it enjoys comparative advantage. But it will not produce all of them since it will simply not be paying to do so. Suppose, D’T’ is the terms of trade line showing the price ratio settled between the two countries. To sum up, bereft of the labour theory of value and expressed in terms of opportunity costs comparative cost theory is still a valid explanation of international trade. Incomplete theory: It is an incomplete theory. Similarly, a professor may be able to teach his own son who is reading in a lower class much better than any school teacher. A comparative advantage in trade is the advantage that one country has over another in the production of a particular good or service. Thus, specialisation, according to the comparative advantage, would lead to the increase in production of both wheat and cloth and the two countries would gain from trading with each other by exporting the goods in which they specialize. But it will not produce all of them since it will simply not be paying to do so. It may be noted that in case of constant opportunity costs, there is complete specialisation, that is, of the two goods a country produces only one commodity, that is, either wheat or cloth after specialisation and trade. Globalisation has led to increased variety for consumers. After trade, the world market price (the price an international consumer must pay to purchase a good) of both goods will fall between the opportunity costs of both countries. Indeed, according to him, international trade is only a special case of inter-regional trade. On the other hand, as more factors of production are drawn from wheat for allocating them to the production of cloth, per unit cost of wheat falls. When production of cloth is expanded productive resources less suited to the production of cloth are drawn into that industry. A country can produce numerous goods. Content Guidelines 2. It may be mentioned here that Ohlin’s criticisms do not invalidate comparative cost theory. Indeed, structural changes are being brought about in these economies.

In the above analysis of opportunity cost version of the comparative cost theory we have assumed that opportunity costs are constant. Introduction Both comparative and absolute advantage are theories of international trade. Suppose the price-ratio line in the foreign market (or what is also called terms of trade line) is given by the price line tt in Figure 23.4. Theory of comparative cost which is the important doctrine of classical economics is still valid and widely acclaimed as the correct explanation of international trade. But if the hour that he devotes to the teaching of his son is devoted to coaching of a student for the degree examination, he will get much more payment than he has to pay a tutor whom he may employ for coaching his son. 5. It is indeed nothing more than an abbreviated account of the condition of supply”. This specialisation is very gainful. 6. It will be seen from this figure that slope of the price- ratio line tt indicates higher price for cloth and lower one for wheat as compared to domestic price-ratio line pp’ since according to tt more wheat can be obtained for a given amount of cloth. Therefore, it would be advantageous for India and U.S.A. to specialise in cloth and wheat respectively. According to Ricardo, if a country has an advantage over two products, it will have an absolute advantage over the one produced with better efficiency, and relative advantage over the one produced with less efficiency. Each individual compares the cost and the income of the various jobs that he could take up and of these he selects that one which is most profitable. Comparative theory states that the value of pr… Note that this criticism about the static character of the comparative cost theory does not invalidate it. On the other hand, India is less efficient in the production of both wheat and cloth, its inefficiency is comparatively less in cloth. Taussig tried to defend Ricardo by pointing out that even if labour theory of value was defective and even if other factors made important contributions to the production of goods, comparative costs could still be based on labour cost alone, if it is assumed that the trading countries are at the same stage of technological development. It is worth mentioning that specialisation necessitates trade or exchange of goods with other countries. However, Ricardo argued that the two countries can still gain from specializing and trading between them if they produce according to their comparative advantage. But the pattern of international trade shows that this is far from reality. Suppose, with given resources, India can produce 20 kgs. Since U.S.A. has a comparative advantage in the production of wheat it will specialise in wheat and would produce OB or 60 units of wheat, whereas India has comparative advantage in the production of cloth and will specialise in cloth production. It is thus evident that the U.S.A. is more efficient in the production of both the commodities as it produces them at a lower labour cost than India. The work of dispensing can be done by a low-paid person, while he can earn much more as a doctor. Cost ratios in the two countries may become equal before either country completely specialises in the production of a single commodity. In a two-commodity world when one country can produce both of them at a lower cost than another, it will pay to it to specialise in the production of a commodity which it can produce at comparatively lower cost and import the other commodity for which it has a comparatively higher costs. In this way both countries are able to increase their level of consumption beyond what is possible in the absence of specialisation. According to this theory, the international trade between two countries is possible only if each of them has absolute or comparative cost advantage in the production of at least one commodity. Comparative advantage describes the economic reality of the work gains from trade for indiv However, Taussig’s defense of Ricardian version of comparative cost theory is poor and invalid. We shall explain what would be the basis of trade between these two countries and how the two would gain from specializing and trading with each other on the basis of comparative advantage or comparative cost. In the equilibrium situation, the two goods would be produced in such quantities where: MRTCW stands for marginal rate of transformation between the two goods. That is, U.S.A. has an absolute advantage in the production of both the commodities. He pointed out that immobility of factors between countries could not serve as a basis for international trade, since immobility of factors is not peculiar the relations between countries but is also present between different regions of the same country.

Economists use the term comparative advantage when describing the opportunity cost of two producers. From these production possibilities, it follows that U.S.A. is more efficient in the production of both wheat and cloth. Comparative cost theory of international trade This theory is developed by a classical economist David Ricardo. Only in the situation of increasing costs, countries would not have complete specialisation. This is important not only for generalizing results How does the total joint output of the two countries increases if U.S.A. specialises in wheat for which it has comparative advantage and India in cloth for which it enjoys comparative advantage ? Even in his theory, popularly known as factor-proportions theory of international trade, comparative costs serve as a basis of international trade. Suppose R is such point on the terms of trade line D’T. 23.2 production possibility curve between wheat and cloth of India is CD. When resources are not equally efficient in the production of the two commodities we may have the situation of increasing costs. It will be seen from Table 23.3 and 23.4 that if U.S. A. reduces the production of cloth by one unit 6 man-hours of labour will be released and if these are used for the production of wheat it will gain 2 units of wheat production. The fundamental cause of international specialisation and hence international trade is the difference in costs of production. Share Your PDF File
The credit of providing an adequate and valid answer to this question goes to Heckscher and Ohlin who explained that comparative costs of different commodities in the two countries vary because of the following factors: 1. The slope of the production possibility curve AB shows the comparative cost ratio of the two commodities in U.S.A. In order to simplify our analysis, we make the following assumptions: 1. This video is all about the Comparative cost theory of international trade based on Neb’s Grade 12’s management students from their Economics subject. joint output of the two countries) will rise by 1 unit of wheat and 0.33 units of cloth as a result of the above shift of man-hours to the products of their comparative advantage. Considering the differences in costs of producing different goods, every country seems to be better suited for the production of certain goods rather than the others. The comparative cost theory explained that different countries would specialise in the production of goods on the basis of comparative costs and that they would gain from trade if they export those goods in which they have comparative advantage and import those goods from abroad in respect of which other countries enjoyed comparative advantage. The terms of trade which will be settled between the two will lie between the production possibility curve CD’ of India and the production possibility curve AB of U.S.A. Even though the U.S.A. is more efficient in the production of both wheat and cloth, she will still gain by having specialisation and trading with India. The principle of comparative advantage in international trade Comparative advantage is typically used with international trade to quantify the benefits of importing and exporting products from particular countries. Their theory, also called the factor proportions theory Also called the Heckscher-Ohlin theory; the classical, country-based international theory states that countries would gain comparative advantage if they produced and exported goods that required resources or factors that they had in great supply and therefore were cheaper production factors. His contribution lies in his inquiring into the question why comparative costs of commodities in different countries differ and offering a satisfactory explanation of it in terms of different factor-proportions required for the production of various goods.
