Thus, the intra-industry trade assumes welfare gain for both the countries. That is, why do firms want to engage in intra-industry and inter-industry trade? Dixit and V.

Yet they are not the only reason. This model discusses the possibility of multiple equilibria including also a situation in which one country specialises in the production of homogeneous good, while the other country specialises in the production of differentiated good. Thus country A, which is capital-abundant and in which capital is relatively cheap, will have a comparative advantage in producing those varieties of the product Y in case of which quality is superior to the marginal quality. 10.2. When the trade takes place and the number of varieties available increases by exactly 50 percent, the borderline consumers will become better off for the two reasons. (iii) When the firms switch from one variety to another, some adjustment costs have to be incurred but these models ignore such costs. There will also be the same agricultural production, prices and incomes. 0000006815 00000 n In other words, there will be the same equilibrium position in both the countries. Some writers have still made attempts to explain the intra-industry trade based on factor endowments by establishing link between the product specifications and the different combinations of the basic factors like labour and capital. Such trade will take place for a number of reasons each of which is related to the types of good being traded. Although there is same volume of total consumption, yet all the consumers will gain from trade due to the use of a wider variety of goods, there being no loss on production side and real wage remaining exactly equal in the two countries. (viii) Each consumer has the same utility function, in which all varieties enter symmetrically. There are two principal reasons for this interest. It is possible to determine the number of firms on the basis of the condition that the labour used in the production of all varieties cannot be more than the fixed supply of labour. The first is the very definition of intra-industry trade-trade in goods of similar factor intensity. (v) These models assume that the opening of trade will not result in the disappearance of any variety. The Case of Spain. Trade theory and common reasons for intra-industry trade The mutual exchange of industrial goods between two countries is neither a new phenomenon nor is there a gap or absence of efforts to explain such trade in the literature. Lawrence and Spiller, in this model, gave two major conclusions. Scale economies provide one reason for such specialization. This model, no doubt, leads to the inference that one half of the range of product varieties will be produced by each country, yet it is unable to tell which varieties will be produced by each country. The theory of comparative advantage suggests that trade should happen between economies with large differences in opportunity costs of production. Neo Hotelling Models. At higher levels of income, consumers would buy more quantity of the superior and lesser of the inferior product. In the conditions of free trade, absence of transport costs and other barriers to trade, trade will take place between these two countries in the given differentiated product. In the absence of trade, the two countries will produce same varieties in the same quantities. It is evident that substitution possibilities across such goods in production will be excellent. Such product differentiation is generally referred as vertical differentiation. The Nature and Causes of Intra-Industry Trade: Back to the Comparative Advantage Explanations? A consumer, in case of whom the ideal variety is closer to the variety being produced, will consume more of the variety than a borderline consumer, will derive larger consumer surplus. Thus, the producer’s surplus remains unchanged even after trade. (a) Intra-industry trade is a trade in which import and exports of simillar or almost similar goods takes place that belongs to the same industry. Two characteristics make intra-industry trade precisely such a setting. 16. What are the reasons for intra-industry trade? Intra-Industry Flows through External Spot Markets (Cell D) Intra-industry economic relations in which firms use purely external spot markets are the most commonly perceived form of IIT. Trade among countries in the European Union has been developing fast, and intra-industry trade much faster than the rest of the trade. There are, at the same time, some consumers who are no longer able to buy their ideal variety. Spiller. Firstly, they can now purchase a variety, which is closer to their ideal variety. ist and explain the welfare effects of intraindustry trade. The producer’s surplus after trade is P1R1S1T. (vii) The average labour requirements decrease with an increase in output. In other words, n represents the index of quality. Neo Chamberlinian Models 3. So the new demand curve is D2. They will be on the margin between purchasing one or the other of the two adjacent varieties. Disclaimer Copyright, Share Your Knowledge In case, the cost function is not linear, there can be the possibility of rise or fall in producer’s surplus. Although distributional change due to free international trade will be quite complex, yet the aggregate consumer’s surplus is likely to be greater than before trade owing to the availability of a larger number of varieties at the lower price. Although there is same volume of total consumption, yet all the consumers will gain from trade due to the use of a wider variety of goods, there being no loss on production side and real wage remaining exactly equal in the two countries. In their case, the consumer’s surplus gain will result from consuming the given variety. In this model, it has been recognised that the differentiation in the product Y is based upon quality. If this industry wants to survive, it should be able to compete well in international markets. 102 0 obj << /Linearized 1 /O 104 /H [ 986 673 ] /L 222077 /E 114877 /N 26 /T 219918 >> endobj xref 102 27 0000000016 00000 n There would be entry of new firms, each one of them producing a new variety. In Fig. TOS4. This idea is initially supported by a specific-factor model analysis. 0000001637 00000 n Second, there is increase in total utility due to the consumption of more varieties. Thus H-O theory can explain the intra-industry trade between the different countries. Intra-industry trade for developing countries We observe that poor countries, even if similar in terms of income, trade much less with each other compared with rich countries Countries where overall labour and capital productivity is low have lower wages and produce less differentiated goods and services Venables. For producing a superior variety of product Y, a firm must make use of more capital per unit of labour. (vii) The product of the other industry Y is differentiated. 10.3, given the linear total cost function, the average cost curve (AC) slopes negatively. It is possible that some consumers become worse off after trade. Falvey. Share Your PPT File, Two-Country Trade Equilibrium | International Trade | Economics. 0000000891 00000 n Higher the magnitude of µ, better can be regarded the quality of the product. Even in this situation, the varieties are spaced evenly along the spectrum. These conclusions have much similarity with the conclusions given by the basic H-O model and the model given by R.E. If there are the increasing economies of scale, then the average cost has the long-run decreasing trend and it is normal that countries, within such conditions, concentrate their limited factors of production on smaller number of huge firms. The consumption of all varieties will, however, take place in both the countries. First, the number of varieties will increase in the capital- abundant country and their number will shrink in the labour-abundant country. Thus, the intra-industry trade assumes welfare gain for both the countries. It extends the basic model to include two factors of production that are employed to turn out a labour-intensive identical product and a capital-intensive horizontally differentiated product. 0000090586 00000 n Share Your Word File Second, the labour- abundant countries will enlarge the scale of production of identical goods, while the capital- abundant countries will expand the scale of production of differentiated products. (iv) Labour is mobile between the two industries. Intra-industry Trade between the European Union and Western Balkans: A Close-up. Horizontal intra-industry trade involves trade in different variety of same good within same stage, same quality and same price bracket. As regards the effect on producers, assuming that there is a linear total cost function and that the number of varieties increases by 50 percent, the analysis can be made with the help of Fig. Share Your PDF File The long run equilibrium after trade will take place at R1 where the output OQ1 will be higher and price OP1 will be lower because price remains equal to average cost. Falvey in 1981. The actual utility function suggested by Krugman can be expressed as: Since the model assumes symmetry, it implies that the price, average cost and output in case of each firm will be the same. 0000003633 00000 n It is possible that the individual consumers may have unique ranking of different varieties in accordance with the characteristics of varieties matching their preferences. Thus, the new equilibrium will be established with a large number of varieties than before. Since the model has been assumed to involve symmetry, exactly half of the varieties will be produced in each country. Since each firm will produce only one variety, it implies that each variety will be turned out in only one of the two countries. This country will, therefore, export superior varieties of the capital-intensive product. In this model, the following assumptions have been taken: (i) There is only one factor of production, labour, in the economic system. (iii) The manufacturing sector produces the differentiated good. 0000002605 00000 n Intra-industry trade gives opportunity for businesses to benefit from the economies of scale, as well as use their comparative advantages. There will be some consumers, who can be turned as borderline consumers. If µ1 < µ, the comparative advantage of A over B, will hold [CB(µ) > CA(µ)], because WB < WA. If each firm employs I amount of labour when l = α + βx and the total fixed labour supply is L, then the number of firms (n) will be-. May 2015 . 0000005946 00000 n 0000003138 00000 n The main characteristic for intra-industry trade is countries import and export same kind of goods but different levels of quality. trailer << /Size 129 /Info 100 0 R /Root 103 0 R /Prev 219907 /ID[<0e6ef37f60db12d557d57907ded5180c>] >> startxref 0 %%EOF 103 0 obj << /Type /Catalog /Pages 97 0 R /Metadata 101 0 R /PageLabels 95 0 R >> endobj 127 0 obj << /S 612 /L 724 /Filter /FlateDecode /Length 128 0 R >> stream 0000006100 00000 n 0000087829 00000 n The 1 See Loertscher and Wolter (1980), Caves (1981), … the exchange of almost identical commodities (intra-industry trade) is important for a variety of reasons. In this connection, it may be pointed out that, like Krugman model, no prediction can be made about which varieties will be produced by each country. Each variety will be produced in equal quantity and will be sold at the same price such that each firm will be obtaining only normal profits. The sources of gains from intra-industry trade between similar economies—namely, the learning that comes from a high degree of specialization and splitting up the value chain and from economies of scale—do not contradict the earlier theory of comparative advantage. After trade, the demand curve is D2. • Within the Ricardo model, intra-industry trade would be unsutainable and market forces would induce countries to pursue full specialization in both production and export • Within the HOS model, with the assumption of no trade cost, some Since each consumer is assumed to consume exactly the same amount (c) of each variety of the product, the total utility function of the consumer will be expressed as: The total spending on all varieties of the good evidently must be equal to the total payment made to labour. The total labour requirements of firm i is measured as: Where xi = Output of variety i of X commodity, β = Co-efficient relating labour requirement and output, and. Using time-series data, a gravity model is developed which enables us to examine the significance of exchange rates and different trade patterns on bilateral trade. 0000058862 00000 n Neo-Heckscher-Ohlin Model 2. Abstract . (vi) There is no limit upon the number of varieties that can be produced by a firm. 0000090507 00000 n The producer’s surplus is given by the area PRST. 0000005542 00000 n Economics, Trade, Intra-Industry Trade, Models of Intra-Industry Trade. On the other hand, vertical intra-industry trade consists of trade in different goods that are part of production value chain of a final good. In intra-industry trade, the level of worker productivity is not determined by climate or geography. Out of them, Y2 is supposed to be the superior variety. For instance, the differentiation based upon colour (colour of a cold drink) is actual and the differentiation based upon taste (taste of cold drink) is perceived. Trade must, however, be balanced as each country exports same number of goods in the same volume and the same price. The Neo-Chamberlinian models related to intra- industry trade include the models developed by the writers like RR. Similarity is identified here by the goods or services being classified in the same “sector”. If the free trade opens, it amounts to the creation of one country, which is twice the size of either of the two original countries because they are identical. Intra-industry trade: A Krugman-Ricardo model and data * Kwok Tong Soo † Lancaster University . H�b```�[�@��A��bl,������nr|[�sX[���\,U�8 ��ǒ��Ԙ�Ф��`�Ct��ָF}�EA�� (ii) There are two sectors in the economies of two countries—manufacturing and agriculture. (iii) There is a large number of firms but the number is determinate. This website includes study notes, research papers, essays, articles and other allied information submitted by visitors like YOU. The intra-industry trade model given by Krugman is indeterminate in one sense. Lancaster terms this situation as ‘prefect monopolistic competition’. Intra-industry trade has been growing rapidly in the past three decades. Likewise, in intra-industry trade, the goods exchanged are not perfect substitutes. It is tangent to AC at R. The firm will produce the quantity OQ and sell at OP price. (viii) Each consumer has a most preferred or ideal variety for which he has the maximum willingness to pay. Intra-industry trade arises if a country simultaneously imports andexports similar types of goods or services. (x) On the supply side, there is free entry and exit of firms, with firms deciding to produce any variety. These models recognise that there is horizontal differentiation of goods. In the absence of trade, D1 is the demand curve. Since each consumer in each county will now consume an amount 0.5 C of each of n varieties, the total utility for him will be: It will evidently signify an increase in the utility of an individual consumer. 0000004869 00000 n The assumption taken by Krugman that all varieties enter the utility function symmetrically has two implications. At low levels of income, consumers are constrained to spend much of their income on the purchase of inferior product Y1, even though they have preference for the superior product Y2. A prominent attempt was made in this regard by R.E. The welfare effect of trade has been analysed by Lancaster in the case of consumers and producers. For the sake of simplicity, it may be assumed that there are two varieties, Y1 and Y2, of the product. 10.3. 0000005312 00000 n 4. The input of capital required to produce one unit of any variety of product Y is µ. 0000001816 00000 n Nonetheless, we believe that these issues deserve some attention on future research. 0000003592 00000 n The production of each variety will be in the same volume and each will be sold at the same price. The key to inducing intra-industry trade is to have intra-industry specialization across countries. D1 is the demand curve for the autarchy variety. 0000002007 00000 n 0000000986 00000 n He developed the Heckscher-Ohlin-Ricardo model, which showed that even with constant returns to scale that intra-industry trade could still occur under the traditional setting. In other words countries will get more economic benefits if they concentrate on producing specific types of products within specific range, according to their comparative advantages rather than producing all ranges of specific products Due to difference in technology, same type of goods a view the full answer Previous question Next question The structure of models referred as Neo- Hotelling models rests upon the approach suggested by K.J. In fact, as new varieties are introduced, some older varieties will disappear altogether from the markets of the two countries. �Գ 5�.���7��ˣ�*�e��A�H�%_���A��,ɗ=�DL�}��j8�H�^�~�.��fp��'�B�ɔPa'�����,�>]����Sy3(���B&���)���qA�>�I���"���s��\19�&��ʳ��T�K�O�\�$Θ��;:CdH���rE@��W�I'Q�6er�1�L_.2�\�d�*l��ty��G�ͅ+/�I(�*�2�l\�h��)��#��@�yG�ɡ ��t�z��100)�et G0@�� �BA�� �A�4$eJJ. As the trade commences, the increased number of varieties will tend the demand curve to shift down. Countries produce different, differentiated products because costs are reduced by producing only a limited range (xi) The cost of producing any variety is the same. Since consumers are evenly distributed along the spectrum, there must be the same level of consumer’s surplus for all the borderline consumers. The demand curve in the case of such consumers is the conventional negatively sloping demand curve for the variety consumed by them. Intra-industry trade is defined as the mutual exchange of similar goods within the same product category (Grubel and Lloyd, 1975, and Greenaway and Milner, 1986). A second broad reason that intra-industry trade between similar nations produces economic gains involves economies of scale. If the unit cost of producing the product of quality n is lower in country A than in country B, i.e., CA(µ) < CB(µ), the country A will have a comparative advantage over B in the production of this variety of product. Half of the production by each firm will be sold in the home market and the remaining half will be exported to the other country. The main weaknesses in these models are as under: (i) The form of utility function taken in Krugman model discounts the possibility that consumers follow same scale of preferences related to the product varieties. Privacy Policy3. %PDF-1.3 %���� List of models of intra-industry trade: 1. Lancaster’s model is based upon the following main assumptions: (i) There are two countries that are identical in all respects. 0000003368 00000 n Let us suppose, the production of one unit of any variety of product Y requires the use of one unit of labour. In the present discussion, we shall mainly consider the model suggested by P.R. 0000023048 00000 n First, intra-industry trade between the two countries did not grow significantly to stimulate overall trade between the two countries. In other words, for all the firms, li, = l, pi, = p and xi, = x. It is now supposed that there is another country which is identical to the first country is every respect. Suppose, for the sake of argument, that we focus on the sector “cars”. 0000114362 00000 n - and intra-industry trade. List and briefly explain for the reasons for Intra-industry and inter-industry trade. It is not even determined by the general level of education or skill. This study proposes alternative reasons to explain an asymmetric intra-industry trade for agricultural products between Canada and the United States after the free trade agreement became effective. The marginal cost curve (MC) is horizontal. Results indicate that intra-industry trade is positively related to product differentiation and scale economies, and negatively related to the levels of protection and foreign ownership in the pre-liberalisation period. Long run equilibrium of the firm is determined at R where quantity produced is OQ and price is OP. Intra-industry trade (IIT), the international two-way exchange of goods with similar input requirements, has been the focus of countless theoretical and empirical studies since the early 1960s. (vi) Out of two factors of production involved, labour is the mobile factor. (iv) The agricultural sector produces a homogeneous good. There will be no trade in agricultural goods. Intra-industry trade is generally a function of product differentiation and may or may not involve intra-firm trade. Furthermore, the high level of intra-industry trade indicated that after the naFta is implemented, there should be no major dislocation of productive activities in these countries due to the expansion in trade. Welcome to EconomicsDiscussion.net! On the basis of the analysis made in Krugman model, A.K. AC is the average cost curve. The income of the consumer and price of the product determine demand for different varieties of product Y. First, the observation of substantial IIT flows runs counter to the predictions of neo-classical trade theory. In this regard, it should be remembered that there can be no such ranking about which there is agreement among all the consumers. This paper develops a model of international trade with a continuum of countries and sectors, which Ricardian combines comparative advantage and increasing returns to scaleTrade consists of both inter. (ii) It is clearly unrealistic to suppose that the product varieties are completely independent of demand. In the post-liberalisation period, however, it is scale economies that explain the inter-industry variations in IIT. Before publishing your Articles on this site, please read the following pages: 1. Each variety, in the case of differentiated product, will be produced by only one firm of only one of the countries and varieties are spaced evenly along the spectrum. This occurs because of differentiation that provides diversity in consumption. There are theoretical reasons for believing that the adjustment costs associated with factor adjustments under intra-industry trade are lower than those under inter-industry trade. In their case, it is difficult to generalise whether they will gain or lose in satisfaction. Krugman, A. J. Venables, C. Lawrence and RT. (v) The factor capital is industry-specific. Content Guidelines 2. 0000006333 00000 n Our mission is to provide an online platform to help students to discuss anything and everything about Economics. (ix) The demand for a given variety depends upon the price of that variety, income of the consumer and the existence of other varieties. Since each country will produce n varieties when the cost of production and sale price is the same as before, the free trade equilibrium will be identical with the equilibrium in the absence of trade. In this model, there is an extension of Krugman-type model in which there is production of identical product under the conditions of constant costs. likely to increase, and potentially, to unsustainable levels. Krugman. (iv) Each firm turns out a different variety of the same commodity, say X. The tangency between D2 and AC curves takes place at R1 where quantity produced is OQ1 and price is OP1. In each time period, every consumer purchases one or both products. Four broad types of good can be distinguished1: The only difference is that there is a lack of movement of factors of production between them. In this model, it is assumed that the initial factor proportions in the two countries are different and that the firms entering the sector producing differentiated products have to incur substantial initial capital outlay. (vi) The industry X produces an identical product. (v) The production is governed by constant returns to scale. α = Labour requirement independent of output. According to Lancaster, the freedom of entry and exit along with equal density of preferences and identity of cost function will lead to the long run equilibrium in which the actual varieties produced will be spaced in an even way along the whole spectrum of varieties. In the category of Neo-Chamberlinian models, we briefly consider another model discussed by A.J. 0000083583 00000 n The trade equilibrium for a typical firm in the manufacturing sector before and after trade can be shown through Fig. Spiller.

Thus, the intra-industry trade assumes welfare gain for both the countries. That is, why do firms want to engage in intra-industry and inter-industry trade? Dixit and V.
