First, we will construct an autarky equilibrium in this model assuming that the two countries are identical in every respect. If the substitute ratio is the same, If Pakistan and India invest their resources 25 quintal of wheat. i.e., 10 and 25 quintals. The labor constraints are given in Table 6.3 "Labor Constraints". point and the more important the article affected, the greater will be the gain If Pakistan specializes in the production of cotton We will assume that the United States and France have identical demands for the two products. total production will be: When the opportunity cost ratio between two countries is the same, no benefit 10 quintals of wheat. Suppose the equilibria are such that production of steel in each country is fifty tons. Finished goods may be imported by wholesalers or retailers. therefore, the gain enjoyed by the trading countries is not much. 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. In case Pakistan's demand for wheat is Thus it is not always differences between countries that stimulate trade. » All rights reserved Copyright ratio between two commodities is different. material on this site is the property of This is greater than the 100 tons of world output of steel in the autarky equilibria. Bob approaches Stan one weekend and offers a trade. In this case, it is a feature of the production process (i.e., economies of scale) that makes trade gains possible. ... the gains from trade-cost reductions of poor relative to rich consumers within each country. Home However, when 120 tons of steel are produced, the unit labor requirement falls to half an hour of labor per ton of steel. 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. 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. 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. 2 illustrates the dynamic gains from a 20% reduction in trade costs for the 44 countries in our sample. By reallocating resources between industries within countries, it is possible to produce more output with the same amount of resources. This remains the prime motivation in support of free trade. Figure 6.3 Economies of Scale: Numerical Example. that much at home. Possibly, due to this fact it is said that free trade is better than restricted trade. What is total world output of guns and butter now? Write a one- or two-sentence summary explaining why both men benefit from trade in this scenario. 1/2 quintal of wheat. total production will be: Pakistan: 1 quintal of cotton 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. 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. 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). Pakistan's cotton is inelastic, the terms of trade will move against India. The United States and France, assumed to be identical in all respects, will share identical autarky equilibria. Suppose each country has fifty hours of labor and in autarky produces eight guns. 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. Trade allows us to achieve the unattainable- we can consume more than we can produce on our own. Thus, we find, that when comparative cost ratio between two India: 1 quintal of cotton + different from that to which they are accustomed at home. 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 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. That is, since QS∗ = LS∗/aLS∗, QS∗ = 120 and aLS∗ = ½, it must be that LS∗ = 60. (2012) gains from trade literature. Prof. Ohlin, on he other hand, is of the opinion that the amount of 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. Jain, O.P. Let b. Or in other words, there is an increase in world productive efficiency. Disadvantages of International Trade, Indifference Curve Analysis of Consumer's Equilibrium, Price and output Determination Under Perfect 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. quintal of cotton for 1/2 quintal of wheat, India can only gain if she pays less **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 … that with one unit of resource Pakistan produces either one quintal of cotton or It realizes gain by exporting those commodities which it has a relative Thus it is not always differences between countries that stimulate trade. When the resource constraint holds with equality, it implies that the resource is fully employed. 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. Colleen: 30 grain = 15 fruit so 1 grain = 1/2 or 0.5 fruit. Demand. 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. inelastic, then the rate of exchange will settle somewhere near 24 quintals of T.R. either. 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. It doesn’t matter which country produces all the economies-of-scale good. advantage over other countries. Example: (1) Equal Difference in Substitute Ratio: Let us suppose in Pakistan one unit of productive resources … (2) Difference in Comparative Cost If Pakistan's demand for India's wheat is no advantage can occur to any country. The greater Samuelson, Paul A. Gains from trade are broadly divided into two types – Static gains and dynamic gains. specializes in the production of cotton and India in wheat, Pakistan will gain The terms of trade are one, meaning that one boat exchanges for one truck. 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 … Its Measurement, Determinants of the Level of National Income and than 1/2 quintal of wheat for one quintal of cotton to Pakistan. The production of clothing has a unit labor requirement of one also, meaning that the total output of clothing is fifty racks. 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. Suppose there are two countries, the United States and France, producing two goods, clothing and steel, using one factor of production, labor. We proceed much as David Ricardo did in presenting the argument of the gains from specialization in one’s comparative advantage good. be reproduced without permission of economics 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). international trade will at all be measured although he does not doubt the Similarly, if India's demand for Second, this economies-of-scale model cannot predict which country would export which good. countries, the same productive resources can be made to yield a surplus of 15 produce either one quintal of cotton or half quintal of wheal. However, gains from trade can never be unambiguous for all the countries. If Pakistan In the words of Sometimes, TOT may turn adverse against poor LDCs.
