Difference between Internal Trade External Trade
■ Trade beyond geographical limits of a country
■ Different countries involved
■ Differences in monetary units or currencies
■ Exchange rate risks

Why liberal International Trade?
■ Stimulus to economic efficiency
■ Contributes to economic growth and rising incomes
![Page 8: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/8.jpg)

Demerits
■ Economic exploitation
■ Domestic entities can be easily outperformed
■ Excessive stress on exports
■ Unsustainable production
![Page 20: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/20.jpg)

■ Even an efficient company may be ousted by an overseas rival with a predatory pricing strategy
■ Some efficient industries may find it difficult to compete for long periods under such conditions.
![Page 21: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/21.jpg)

■ International markets are not a level playing fields
■ Favour of foreign goods threaten the survival of infant industries
■ Countries with surplus products may dump them
■ New industries may find it difficult to enter and establish if foreign competitors already enjoy economies of scale and easy access to domestic markets.
![Page 22: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/22.jpg)

Agricultural economies
■ Face unfavourable terms of trade (ratio of export prices to import prices)
■ Whereby their export income is much smaller than the import payments they make for high value added imports,
■ Leading to large cads and
■ Subsequently large foreign debt levels.
![Page 23: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/23.jpg)

■ Profit-driven exhaustion of natural resources
■ Substantial environmental damage
■ Possible shift towards a consumer culture
■ Change in patterns of demand in favour of foreign goods /services
![Page 24: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/24.jpg)

■ Trade cycles likely to get transmitted
■ Risky dependence of underdeveloped countries
■ Impairs economic autonomy and endangers their political sovereignty.
■ Widespread exploitation and loss of cultural identity
![Page 25: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/25.jpg)

■ Welfare of people may be ignored or jeopardized for the sake of profit.
■ Cause shortages and inflation
■ Lack of transparency and predictability in respect of many aspects related to trade policies of trading partners.
![Page 26: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/26.jpg)

■ Excessive exports
■ Import of harmful products
■ Too much export orientation may distort actual investments away from the genuine investment needs of a country
■ May breed rivalry on account of severe competition
![Page 27: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/27.jpg)

Discuss
Free action of market forces can be
unprofitable for the less developed countries.

Theories of international trade
■ The mercantilists’ view of international trade
■ Maximize exports in order to bring in more “specie”
■ Minimize imports by imposing very high tariffs on foreign goods.
■ Trade is a ‘zero-sum game’,
![Page 29: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/29.jpg)
© ICAI, 2013
The Theory of Absolute Advantage
■ Adam smith
■ International trade is not a zero-sum game.
■ Absolute cost advantage is the determinant of mutually beneficial international trade
![Page 30: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/30.jpg)
© ICAI, 2013
■ A country will specialize in the production and export of a commodity in which it has an absolute cost advantage
■ Absolutely lower production cost
![Page 31: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/31.jpg)
© ICAI, 2013
■ The principle of division of labour
■ Value of goods is determined by measuring the labour incorporated in them.
■ Hypothetical two countries and two commodities model (2x2 model).
![Page 32: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/32.jpg)
Output per Hour of Labour
Commodity Country A Country B
Wheat
(bushels/hour) 6 1
Cloth (yards/hour)
4 5
![Page 33: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/33.jpg)
© ICAI, 2013
■ country A would specialise completely in production of wheat and
■ country B would specialise completely in cloth.
![Page 34: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/34.jpg)
© ICAI, 2013
Trade – For Country A
■ Country A exchanges six bushels of wheat (6W) for six yards of country B’s cloth (6C)
■ 6W =6C
■ Domestic Exchange
■ 6W = 4C
■ Gain 2C = saves half an hour or 30 minutes of labour time
![Page 35: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/35.jpg)
© ICAI, 2013
6W that country B receives from country A
■ Require six hours of labour time to produce in country B
■ These same six hours can produce 30C in country B (6 hours x 5 yards of cloth per hour)
■ Country B gains 24C,(30-6) or saves nearly five hours of work.
![Page 36: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/36.jpg)
© ICAI, 2013
Outcome
■ Both countries can produce larger quantities of commodities which they specialize in.
■ If they specialise but do not trade freely country A’s consumers would have no wheat, and country B’s consumers would have no cloth
![Page 37: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/37.jpg)
© ICAI, 2013
A second case
■ What happens if
■ Country A has absolute advantage in the production of both commodities
■ Country B has absolute disadvantage in the production of both commodities
■ There is still scope for mutually beneficial trade
![Page 38: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/38.jpg)
Output per Hour of Labour
![Page 39: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/39.jpg)
© ICAI, 2013
Country B has a comparative advantage in Cloth.
■ B’s labour is only half as productive in cloth but
■ Six times less productive in wheat compared to country A
■ (4:2) cloth (6:1) wheat
![Page 40: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/40.jpg)
© ICAI, 2013
Country A
■ Has a comparative advantage in production and exporting wheat.
■ The absolute advantage is greater in wheat
■ Wheat (6:1) cloth (4:2),
![Page 41: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/41.jpg)
© ICAI, 2013
Outcome for Country A
■ Country A’s absolute advantage is greater in wheat
■ Country A has a comparative advantage in producing and exporting wheat.
■ Country A specialise in wheat, and exports some in exchange for country B’s cloth
![Page 42: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/42.jpg)
© ICAI, 2013
Outcome for Country B
■ Country B’s absolute disadvantage is smaller in cloth
■ its comparative advantage lies in cloth production.
■ B should specialise in cloth and export some of it in exchange for country A’s wheat
![Page 43: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/43.jpg)
© ICAI, 2013
Both nations can gain from trade
■ Country A - 6W for 6C from B
■ A gain 2C (= half an hour of labour)
■ Country B gets 6W
■ Six hours of labour time to produce in country B
■ B can use the 6 hours for cloth = 12C ,exchange 6 C
■ Gain is 6C ( = 3 hours of labour)
![Page 44: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/44.jpg)
© ICAI, 2013
Other possibilities
■ Any thing above 4 C (Cloth) would be a gain for A
■ In country B, 6W = 12C
■ Country B gains to the extent that it can give up less than 12C for 6W from country A
![Page 45: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/45.jpg)

The Heckscher-Ohlin Theory of Trade
■ Heckscher-Ohlin
■ (H-O) model
■ Factor-Endowment Theory of Trade
■ Modern Theory of Trade,
■ Heckscher-Ohlin-Samuelson theorem.
![Page 46: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/46.jpg)
© ICAI, 2013
Factor endowment
■ Overall availability of usable resources including both natural and man-made means of production
■ Only the two most important factors—labour and capital—are taken into account
![Page 47: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/47.jpg)
© ICAI, 2013
Two countries
■ Have different factor endowments
■ Identical production function
■ Identical preferences
■ Different factor prices in the beginning.
■ Have different cost functions.
![Page 48: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/48.jpg)
© ICAI, 2013
Note
■ Comparative advantage in cost
of production is explained
exclusively by the differences
in factor endowments of the
nations.
![Page 49: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/49.jpg)
© ICAI, 2013
Reason for trade
■ Difference in factor endowments
■ Capital abundant
■ Labour abundant
■ Exports depend on endowment of resources
![Page 50: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/50.jpg)

Two theorems
■ Heckscher-Ohlin Trade Theorem and
■ Factor-Price Equalization Theorem.
![Page 51: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/51.jpg)
© ICAI, 2013
The Heckscher-Ohlin Trade Theorem
■ A country tends to specialize in the export of a commodity whose production requires intensive use of its abundant resources
■ Imports a commodity whose production requires intensive use of its scarce resources.
![Page 52: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/52.jpg)
© ICAI, 2013
The ‘Factor-Price Equalization’
■ International trade tends to equalize the factor prices between the trading nations
■ International trade equalizes the absolute and relative returns to homogenous factors of production and their prices.
![Page 53: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/53.jpg)
© ICAI, 2013
■ If the prices of the output of goods are equalized between countries engaged in free trade, then the price of the input factors will also be equalised
■ Foreign trade eliminates the factor price differentials.
![Page 54: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/54.jpg)
© ICAI, 2013
For example
■ When there is more demand for
labour intensive goods
■ The expanding labour intensive industry absorbs relatively more labour than the amount released by the contracting capital goods industry
![Page 55: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/55.jpg)
© ICAI, 2013
■ The price of labour goes up,
■ Its relative price increases,
■ The relative price of capital declines
![Page 56: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/56.jpg)
© ICAI, 2013
■ When the prices of the output of goods are equalized between countries as they move to free trade,
■ Then the prices of the factors (capital and labour) will also be equalized between countries.
■ Product mobility and factor mobility become perfect substitutes.
![Page 57: Chapter 4 Unit I Theories of International Trade](https://reader031.fdocuments.us/reader031/viewer/2022013009/61ce5d14a749ef62f20a4393/html5/thumbnails/57.jpg)

New Trade Theory (NTT)
■ Explains why developed and big countries are trade partners when they are trading similar goods and services.
■ Economies of Scale:
■ Network effects
■ ‘bandwagon effect’
