(glasses) for every ) to find an output, usually , Q {\displaystyle x} Let's put this into more concrete terms with an example. The unitary opportunity cost is the amount of an object we lose for every other one object. Before trade, truck producers in Roadway could exchange a truck for half a boat. 214 High Street, . s 1 Q Consider two countries producing two products – digital cameras and vacuum cleaners. Comparative advantage is a theory about the benefits that specialization and trade would bring, rather than a strict prediction about actual behavior. Work by yourself in that instance. m 3 Usually, a question will define the output. 1 However, this does not tell us how much chocolate ice cream scoops we waste per vanilla ice cream scoops. 2 , is a comparison of the slope Q 0 for every 1 However, since he cannot convincingly give any reason as to why you, the seller, should buy this product, he will fail to change the face of the phone industry – his desire was not met. 2 Finally, once all is done, we add in a changing variable, Q However, this rarely happens, if at all. Q h James Portley would like to advertise his new product that may very well change the face of the phone industry. y {\displaystyle b} ) Hint: Look at the PPF at the beginning of the section. Q in our formula. There is a multitude of ways to find the slope in this instance, yet only one such calculation will be shown. ) By specializing people's talents, everyone as a whole can gain from the trade of talents. "While it may be true that working with other individuals is beneficial when you do not know how to do a task, it does not necessarily mean that working with other individuals is always best if the task you do is either similar or identical. h The following two tables show the production of autos and wheat for two countries, Iospain and Vostren, before and after they specialize in one of the goods, as well as consumption before and after the countries start … jwplayer(“myElement”).setup({ file: “ image: “jwplayer/poster.jpg”, title:”Example Video Title”, width:692, height:389 }); . {\displaystyle x} The total gain from trade can be measured by the movement from E to C 1. 1 According to Smith, the gains from trade arise form the advantages of division of labour and specialisation—both at the national and international level. m That is what we proved last time, and this is why the slope or the unitary opportunity cost can be used in the table above and still prove the same thing we proved: Harry has a comparative advantage in making boxes and Steven has a comparative advantage in making glasses. x One of the main determinants ofinternational trade Most misunderstood aspect of international trade? by evaluating every input For example the Canadian economy which is rich in low cost land is able to exploit this by specializing in agricultural production. 2 Machinery comes All parties enjoy a higher standard of living with specialization and trade. ( 2 Gains from specialization: Countries may gain economies of scale from specialization, experiencing long run average cost declines as output increases. m is used to deleniate Steven's line, to help the find the loss of while Steven's slope {\displaystyle m} 2 Before we get to the calculation, we need to know the definition of unitary opportunity cost. | x b . 2 , This feature has been incorporated into many state-of-the-art quantitative trade models, and has been shown to deliver significant additional gains from international trade. The gains from trade is the gain in consumer and producer surplus over what it was before trading. . {\displaystyle H(Q_{2})} Q Boston House, Keep in mind, however, that James could have declined. -graph. If Harry wants to find the optimal unit of boxes for both him and Steven, he needs to find the number of units that will not go over either Steven's or Harry's opportunity cost of production. , given that Q Substitute any rational value for 1 Intraindustry Specialization and the Gains from Trade Paul R. Krugman Massachusetts Institute of Technology Several recent empirical studies of trade suggest that interindustry specialization and trade, which reflect the conventional forces of comparative advantage, are also accompanied by intraindustry 2 The point at which Harry chooses to produce is at We can divide each by two and split them between the countries, this means that the US now gets 48 apples, and 11 papayas, and Mexico gets 15 apples, and 13 papayas. -intercept is defined as the ordered pair 1 . A production possibility frontier (PPF, for short) is a graphical curve or line that represents the production of two goods for any entity. {\displaystyle {3 \over 2}} Q {\displaystyle Q_{2}=x} Final point to understand before we move on, the slope of the answer above can be found using any point along the PPF of Steven's production line. y . y {\displaystyle s} − 1 The examples shown in the previous subsections are in no way intended to be realistic. {\displaystyle Q_{2}=2} 1 In the richest advanced countries, the comparative advantage is mainly in specializing in producing and exporting high-value and high-technology goods and high-knowledge services. Remember that the exchange of goods, services, or resources between one country and another. 1 r {\displaystyle y=mx+b} Q x Review the previous sections so that you know the numbers to look for. ( , Find Steven's slope of the PPF when producing the reciprocal, − Remember what we learned at the beginning? {\displaystyle Q_{2}} ) ) Several recent empirical studies of trade suggest that interindustry specialization and trade, which reflect the conventional forces of comparative advantage, are also accompanied by intraindustry specialization, which reflects scale economies and consumers' taste for a diversity of products. Now that we know what a slope is, we can now find it in our graph. The methods of calculation we learned now helps us answer the ultimate question here: should Harry make the trade? The most common intercept (and the one we will focus on in this economics WikiBooks) is the m ) Do not write any letters in your answer. Imagine that James Portley and Quincy Adams met one day. {\displaystyle 1\,Q_{2}} m how do people and nations gain from specialization and trade? , The UK specializes totally in producing vacuum cleaners – doubling its output to 1200. Those values are called intercepts. , 1 It is important to realize this lesson: rational individuals will gain from the trade if and only if each individual agrees that trading is better than by working by themselves. y The clip is safe for work and classroom use. 2 {\displaystyle Q_{1}} gained. {\displaystyle x} Find Steven's slope of the PPF when producing the reciprocal. Say those two people are co-founders of MetalPlastic, a company that makes and designs phones. 6 represents The ability of a country to produce a good at a lower cost than another country can. {\displaystyle x} This is usually useful whenever working with production. -axis, denoted as If the nations are now fully specialized based on comparative advantage, the total gains from specialization and trade are: 50 units of rice and 50 units of corn.

In our example above, for country A, every extra unit of good Y produced involves an opportunity cost of 2 unit of good X. 2 {\displaystyle (3,2)} | {\displaystyle Q_{1}} . x x r {\displaystyle x} The lines are colored differently. is any positive rational number defined by the equation of the graph -intercept, defined as 2 Terms of trade and the gains from trade. 1 from an input West Yorkshire, Here's another example question that could have been asked, which is identical to the one above, only defined differently: Here, the "defined output" would have been By producing goods or services that have the lowest opportunity cost and then trading to people and nations end up being more efficient and productive. x Opportunity cost and comparative advantage using an output table. , where each point will be connected linearly. 1 Therefore, the UK has a comparative advantage in vacuum cleaners. Absolute advantage occurs when a country or region can create more of a product with the same factor inputs. Therefore, the number of ) 2 The only difference will be the number of boxes traded for one 1 glass. r Take this example: if we want to choose between having three scoops of chocolate ice cream to two scoops of vanilla ice cream, we would say that the opportunity cost of having three chocolate ice cream scoops is two scoops of vanilla ice cream. After Portley made his new product, Adams decided to risk the money they have to present their new product. {\displaystyle x} 1 2 and Q , and Steven, So both countries are better off and get more of both goods when they specialize and trade! For any individual who is color blind, Harry is the top diagonal line, and Steven is the bottom diagonal line. The greater are the differences, the greater the gains (Ethier, 2008). 2 This consequence of rationality is built into its definition. Countries will usually specialise in and export products, which use intensively the factors inputs, which they are most abundantly endowed.
