quintal of cotton for 1/2 quintal of wheat, India can only gain if she pays less Give a specific numerical example and show it on your graphs. CHAPTER 3 INTERDEPENDENCE AND THE GAINS FROM TRADE Example: Comparative Advantage for Example: Comparative Advantage for computer computer In US: producing one computer requires 100 labor hours, which instead could produce 10 tons of wheat So, the opp. specializes in the production of cotton and India in wheat, Pakistan will gain Suppose each country has fifty hours of labor and in autarky produces eight guns. existence of such gains". from trade. The greater can occur through specialization to the countries concerned. If output of both goods rises, then surely it must be possible to find a terms of trade such that both countries would gain from trade. 4. ∗All starred variables are defined in the same way but refer to the production process in France. Suppose further that India, with one unit of resources is also able to Corey: 18 grain = 6 fruit so 1 grain = 1/3 or 0.33 fruit. All rights reserved Copyright concepts. Bob approaches Stan one weekend and offers a trade. Learn how a simple model can show the gains from trade when production involves economies of scale. Total = 2 quintals of cotton + 35 quintals of wheat. Finished goods may be imported by wholesalers or retailers. The actual rate of exchange will settle on the specialization or exchange be of any advantage to India and Pakistan? This surplus of 15 quintals of wheat can be mutually shared by countries, the same productive resources can be made to yield a surplus of 15 Which country would benefit from trade… If the two countries trade at a rate of exchange of 2 digital cameras for one vacuum cleaner, the post-trade position will be as follows: The UK exports 420 vacuum cleaners to the USA and receives 840 digital cameras The USA exports 840 digital cameras and imports 420 vacuum cleaners Consider the example of trade in two goods, shoes and refrigerators, between the United States and Mexico. This is the most visible part of trade as most finished goods identify the nation where they were manufactured. If these countries were open to trade, which country would export shirts? In our example given above, the difference in the cost ratio is small Suppose there are two countries, the United States and France, producing two goods, clothing and steel, using one factor of production, labor. point and the more important the article affected, the greater will be the gain specialization. and Economic Growth, Theories However, gains from trade can never be unambiguous for all the countries. As noted earlier, the dynamic gain for country i, λ i dyn, is given by Eq.. 820-829. different from that to which they are accustomed at home. 3. The gains from international trade arise because of the diversity in the therefore, the gain enjoyed by the trading countries is not much. Also, it may not matter whether your country ends up producing the economies-of-scale good or not because both countries will realize the benefits as long as an appropriate terms of trade arises. total production will be: Pakistan: 1 quintal of cotton that much at home. International Trade, Advantages and Let the unit labor requirement for steel vary as shown in Figure 6.3 "Economies of Scale: Numerical Example". T.R. elastic, then the terms of trade will be more in its favor. No part of this website may In Japan: producing one computer requires125 labor hours, which instead could produce … © 2010 - 2015, Origin and Purpose of When the resource constraint holds with equality, it implies that the resource is fully employed. be reproduced without permission of economics The production decision is how to allocate labor between the two industries. Or in other words, there is an increase in world productive efficiency. Let labor productivity in butter production be ten pounds per hour at all levels of output and productivity in gun production be one-half of a gun per hour when gun production is less than ten and two-thirds of a gun per hour when production is ten or more. Africa) but those countries ought to produce goods that are good for the population as a whole instead of tryiing to invest in the production of products of developed countries. Second, this economies-of-scale model cannot predict which country would export which good. Calculate the quantity of butter produced by Country A and Country B. in their own countries, the total production will be: Pakistan: 1 quintal of cotton + Includes lessons in micro and macro. The important result here is that it is possible to find a reallocation of labor across industries and countries such that world output of both goods rises. The graph shows that when fifty tons of steel are produced by the economy, the unit labor requirement is one hour of labor per ton of steel. b. only if she can get more than 1/2 quintal of wheat for one quintal of cotton We will assume that the United States and France have identical demands for the two products. Now we have to determine what the possible grains from trade are. 2 illustrates the dynamic gains from a 20% reduction in trade costs for the 44 countries in our sample. Resource constraint. the difference in the cost ratio, the larger is the total gain. economicsconcepts.com. (1) Equal Difference in Substitute Ratio: Let us suppose in Pakistan one unit Despite the lack of incentive to trade in the original autarky equilibria, we can show, nevertheless, that trade could be advantageous for both countries. India: 1 quintal of Cotton + These goods are homogeneous, meaning that consumers and producers cannot differentiate between shoes from Mexico and shoes from the U.S.; nor can they differentiate between Mexican or American refrigerators.From Table 1, we can see that it takes four U.S. workers to produce 1,000 pairs of shoes, but it takes five Mexican workers to do so. Give an example of trade gains using comparative advantage Countries benefit if they specialise in the production of a good or service in which they have a comparative advantage ie a lower internal opportunity cost. The labor constraints are given in Table 6.3 "Labor Constraints". More specifically, we will assume that the unit labor requirement falls as industry output rises. cost of a computer is 10 tons of wheat in US. Other Gains from trade •Scale economies and trade –Without trade, a small country produces everything at small scale and high cost –By specializing in fewer goods and exporting, cost of each goes down Lecture 2: Gains20 In this revision video we work through an example of how specialisation and trade can lead to welfare gains using supply and demand analysis. wheat for one quintal of cotton. By shifting production in one country to production of the good that exhibits economies of scale and shifting production toward the other good in the other country, it is possible to raise total output in the world with the same total resources. intraindustry trade. For example, it is possible to show that countries that are identical in every respect might nevertheless find it advantageous to trade. In this case, it is a feature of the production process (i.e., economies of scale) that makes trade gains possible. international trade will at all be measured although he does not doubt the It doesn’t matter which country produces all the economies-of-scale good. Since at fifty tons of output, the unit labor requirement is one, it means that the total amount of labor used in steel production is fifty hours. Monopolistic/Imperfect Competition, Theory of Factor Pricing OR Theory of Distribution, National Income and There are gains from trade between the two countries. Calculate how many pounds of butter each country produces in autarky. and India in wheat, the total product with the same productive resources will All that is necessary is for one of the two countries to produce its good with economies of scale and let the other country specialize in the other good. They buy what to them Table 6.4 "Initial Exogenous Variable Values", Figure 6.3 "Economies of Scale: Numerical Example", Table 6.5 "Autarky Production/Consumption". Assume the production technology is identical in both countries and can be described with the production functions in Table 6.1 "Production of Clothing". If Pakistan's demand for India's wheat is for one quintal of cotton and if India's demand for Pakistan's cotton is We may now briefly enlist the gains resulting from international trade: 1. International specialisation and geographical division of labour lead to optimum allocation of world resources making it possible to have the most efficient use of them. He then proposes that Stan trade him a … Write a one- or two-sentence summary explaining why both men benefit from trade in this scenario. Static gains from trade refer to the increase in production or welfare of the people of the trading countries as a result of the optimum allocation their given factor-endowments, if they … Possibly, due to this fact it is said that free trade is better than restricted trade. of cotton or 25 quintals of wheat. » We Website to help learn economics. total production will be: When the opportunity cost ratio between two countries is the same, no benefit That is, since QS∗ = LS∗/aLS∗, QS∗ = 120 and aLS∗ = ½, it must be that LS∗ = 60. As long as one country does so and trades it with the rest of the world, trade gains are possible. » Gains From country tries to specialize in the production of those commodities in which its Throughout the remainder of the paper, we not only use scatter plots, as in Fig. Note that it is assumed that the unit labor requirement is a function of the level of steel output in the domestic industry. material on this site is the property of What is total world output of guns and butter now? In case Pakistan's demand for wheat is 1/2 quintal of wheat. We will introduce the concept of Comparative Advantage and discuss how gains from specialization allow us to use our resources efficiently. Since the unit labor requirement of steel is one-half when 120 tons of steel are produced by one country, the total labor can be found by plugging these numbers into the production function. If Pakistan Thus it is not always differences between countries that stimulate trade. Gains from trade are broadly divided into two types – Static gains and dynamic gains. (2) Difference in Comparative Cost According to the classical economists, the gains from trade result from the advantages of division of labour and specialisation both at the national and international levels. However, when 120 tons of steel are produced, the unit labor requirement falls to half an hour of labor per ton of steel. countries is the same, no gain can arise from international trade. If France allocates its remaining forty hours of labor to clothing production and if the United States specializes in clothing production, then production levels in each country and world totals after the reallocation of labor would be as shown in Table 6.6 "Reallocated Production". To this bargain, Pakistan won't agree Identify this point in your graphs. If Pakistan and India invest their resources It realizes gain by exporting those commodities which it has a relative For example, an aircraft assembled in the United States will be considered an American product even if it contains components and parts from Europe and Japan. For example, Sal (an individual) specializes in producing educational videos, and Bangladesh (the country) specializes in producing textiles. The autarky production and consumption levels are summarized in Table 6.5 "Autarky Production/Consumption". Note that since production technology is assumed to be the same in both countries, we use the same unit labor requirement in the U.S. and French production functions. Countries that are identical would have no natural incentive to trade because there would be no price differences between countries. Employment, Economic Development 2, but we also use four countries to highlight our results: Bulgaria, Portugal, France, and the United States. 10 quintals of wheat. Ratio: When comparative cost ratio in two Suppose the exogenous variables in the two countries take the values in Table 6.4 "Initial Exogenous Variable Values". A simple economies-of-scale model does not predict which country would export which good. Next, suppose Country A produces all the guns in the world while Country B specializes in butter production. Table 6.4 Initial Exogenous Variable Values. For example, if France were to export sixty tons of steel and import thirty racks of clothing, then each country would consume seventy units of clothing (twenty more than in autarky) and sixty tons of steel (ten more than in autarky). Its Measurement, Determinants of the Level of National Income and For example, it is possible to show that countries that are identical in every respect might nevertheless find it advantageous to trade. than 1/2 quintal of wheat for one quintal of cotton to Pakistan. What is the total world output of guns and butter in autarky? us now go back to actual exchange. quintals of wheat. Similarly, if India's demand for Roadside moves along its production possibilities curve to point B, at which the curve has a slope of −1. For example, suppose we let France produce 120 tons of steel. For example Poor countries can trade production of primary goods with manufactered goods produced by developed countries. India: 1 quintal of cotton + The production of steel is assumed to exhibit economies of scale in production (see Table 6.2 "Production of Steel"). Start studying Chapter 4: Gains from Trade. Consider France and the UK producing two goods cars and wine. Consider Selkirk’s and Pirate Jack’s gains from trade when they produce and trade the good for which they hold a comparative advantage. At the same time, it is clear that somewhere along the way, many people’s attitude towards trade liberalisation and the free movement of goods and labour drastically changed. Total product = 2 quintal of cotton + 1 quintal of wheat without Despite these differences with other models, the main similarity is that gains from trade arise because of an improvement in productive efficiency. Theory of International Trade Jhingan, “International Economics” Konark Publication, New Delhi. Pakistan and India. With identical prices, there would be no incentive to trade if trade suddenly became free between the two countries. Suppose that without trade the workers in each country spend half their time producing each good. This remains the prime motivation in support of free trade. QC = quantity of clothing produced in the United States, LC = amount of labor applied to clothing production in the United States, aLC = unit labor requirement in clothing production in the United States and France (hours of labor necessary to produce one rack of clothing). Given the resources and technology in a country, it is specialisation in production 0П the basis of comparative advantage and trading which enables each country to exchange its goods for the goods of another country. M. C. Kemp, “The Gains from Trade and the Gains from Aid: Essays in International Trade Theory” Routledge. either. He has over twenty years experience as … Harrod: "A country gains by foreign trade if Figure 6.3 Economies of Scale: Numerical Example. Gains from trade is the net gain achieved by countries, organizations or individuals from trade. To see how, we present a simple example using a model similar to the Ricardian model. countries differs, then gain arises from international trade, let us suppose now that with one unit of resource Pakistan produces either one quintal of cotton or He doubts if the gain from Gains from trade results "when countries specialize in producing the goods they can produce at the lowest cost relative to other participants" ("Gains from trade," 2016). India with the same resources produces either one quintals In order to do this we have to have some initial production values for the goods. Disadvantages of International Trade, Indifference Curve Analysis of Consumer's Equilibrium, Price and output Determination Under Perfect The welfare improvement arises because concentrating production in the economies-of-scale industry in one country allows one to take advantage of the productive efficiency improvements. conditions of production (natural or acquired) in different countries. Further, trade policy is often designed by the advanced countries in such a way that it reduces benefits of the LDCs from trade. India won't agree to it because in her own country she can get one Will In this case, it is a feature of the production process (i.e., economies of scale) that makes trade gains … Besides the abovementioned literature on the extensive margin effects of trade liberalization, our paper is most closely related to the recent Arkolakis et al. Example: (1) Equal Difference in Substitute Ratio: Let us suppose in Pakistan one unit of productive resources … Suppose the equilibria are such that production of steel in each country is fifty tons. First, we will construct an autarky equilibrium in this model assuming that the two countries are identical in every respect. Geoff Riley FRSA has been teaching Economics for over thirty years. For this example, I will assume that the US was producing 42 apples, and 7 papayas, and that Mexico was producing 9 apples, and 8 papayas. Then we will show how an improvement in world productive efficiency can arise if one of the two countries produces all the steel that is demanded in the world. of productive resources produces either one quintal of cotton, or half quintal is No. Use the terms comparative advantage in your explanation. This can be illustrated by taking Production of steel. The terms of trade are one, meaning that one boat exchanges for one truck. (e.g. By reallocating resources between industries within countries, it is possible to produce more output with the same amount of resources. produce either one quintal of cotton or half quintal of wheal. We proceed much as David Ricardo did in presenting the argument of the gains from specialization in one’s comparative advantage good. The problem with these initial autarky equilibria is that because demands and supplies are identical in the two countries, the prices of the goods would also be identical. of wheat. Free trade is based on the benefits espoused of comparative advantage. A measure of total gains from trade is the sum of consumer surplus and producer profits or, more roughly, the increased output from specialization in production with resulting trade. Gains from trade may also refer to net benefits to a country from lowering barriers to trade such as tariffs on imports. If Pakistan and India invest two units of productive resources separately The gain from international trade can arise only if the opportunity cost The United States and France, assumed to be identical in all respects, will share identical autarky equilibria. ... the gains from trade-cost reductions of poor relative to rich consumers within each country. least. If Pakistan's demand for India's wheat is inelastic, terms of If the substitute ratio is the same, advantage over other countries. QS = quantity of steel produced in the United States, LS = amount of labor applied to steel production in the United States, aLS(QS) = unit labor requirement in steel production in the United States (hours of labor necessary to produce one ton of steel). inelastic, then the rate of exchange will settle somewhere near 24 quintals of Before trade, Roadway is producing at point A in Panel (a) and Seaside is producing at point A′ in Panel (b). trade will be more in India's favor. For example, if you're better at growing apples than wheat then you can gain by exporting apples and importing wheat. In theory, the global economy would be vastly more inefficient if nations were forced to produce all the goods consumed within their borders or even produce goods they could otherwise purchase at lower cost abroad. gain from international trade is very complicated. from India. This can be illustrated by taking numerical examples. of Under Development, Theories Prof. Ohlin, on he other hand, is of the opinion that the amount of Colleen: 30 grain = 15 fruit so 1 grain = 1/2 or 0.5 fruit. Pakistan's cotton is inelastic, the terms of trade will move against India. For example, a trade-induced increase in the price of food has a stronger negative e ect on low-income consumers, who typically have larger food expenditure shares than richer consumers. Trade works because it allows countries and organizations to focus on their competitive advantages. numerical examples. We assume that labor is homogeneous and freely mobile between industries. Countries that are identical in every respect can benefit from trade in the presence of economies of scale. If Pakistan specializes in the production of cotton David Ricardo in 1817 first clearly stated and proved the principle of comparative advantage, termed a … of Economic Growth. intensity of reciprocal demands, and it will remain within two extreme limits, comparative cost advantage is greatest or the comparative disadvantage is the The main reason the presence of economies of scale can generate trade gains is because the reallocation of resources can raise world productive efficiency. Fig. + 10 quintal of wheat. If Pakistan specializes in the production of cotton and India in wheat the In the words of Terms of Trade in Economics: Definition, Formula & Examples 4:23 Gains from Trade: Definition & Example 4:41 Go to Foreign Exchange and the Balance of Payments: Help and Review Sometimes, TOT may turn adverse against poor LDCs. 1/2 quintal of wheat. **trade** | the exchange of goods, services or resources between one economic agent and another **international trade** | the exchange of goods, services, or resources between one country and another **gains from trade** | the ability of two agents to increase … Suppose there are two countries with the same production technologies. Some features of the economies-of-scale model make it very different from the other models of trade, such as the Ricardian or Heckscher-Ohlin models. inelastic, the rate of exchange will settle somewhere near 11 quintals of wheat Learn vocabulary, terms, and more with flashcards, games, and other study tools. i.e., 10 and 25 quintals. (2012) gains from trade literature. no advantage can occur to any country. The answer Competition, Price and Output Determination Under Monopoly, Price and Output Determination Under seems cheap and sell what to them seems dear. Roadside will produce more trucks (and fewer boats). The final conclusion of this numerical example is that when there are economies of scale in production, then free trade, after an appropriate reallocation of labor, can improve national welfare for both countries relative to autarky. That leaves fifty hours of labor to be allocated to the production of clothing. Samuelson, Paul A. and when the traders find that there exists abroad a ratio of prices very Bob suggests that he completely specialize in lawn mowing while Stan specializes more in driveway sweeping, sweeping 51 driveways and mowing 24.5 lawns. Each Let be: We find thus that when opportunity cost ratio is different between two Jain, O.P. That means more output with less labor. Identify a terms of trade (guns for butter) that will assure that each country is at least as well off after trade as before. The production of clothing has a unit labor requirement of one also, meaning that the total output of clothing is fifty racks. because by transferring productive resources from cotton to what she can produce All the In autarky, it took 100 hours of labor for two countries to produce 100 tons of steel. Home Thus it is not always differences between countries that stimulate trade. For example, at the beginning of nineties about 50 regional trade agreements were in force, whereas there are currently about 270 enforced agreements. International Trade. Trade allows us to achieve the unattainable- we can consume more than we can produce on our own. 2. Thus, we find, that when comparative cost ratio between two 25 quintal of wheat. Now it would take France 60 hours to produce 120 tons. This is greater than the 100 tons of world output of steel in the autarky equilibria. ratio between two commodities is different. REFERENCES M.L. in their own countries separately for the production of cotton and wheat, the Now, suppose, for example, that one country imports a large volume of few goods from other countries, and another country has the same volume of import even ... the trade gains between countries concerned with this type of international trade, 7 .
