Mercantilism(SS) Keynes
17th and 18th centuries– Discourage imports and encourage exports to
increase country’s wealth.– Zero-sum game
(Positive-sum game or n-sum game)
Q. Mercantilism implies that international trade is a ________ sum game.
2
New Mercantilism
(Bergsten and Subramanian)
November 2008: first Summit of G-20
Q. What is G-20? What was its predecessor?
Q. What was the need for the Summit in 2008?
The Summit:• Inter alia, pledged to promote world trade• Yet G-20 countries erected new distortions:
– Raised tariffs: Brazil, India, Russia– New licensing requirements for imports: Argentina,
Indonesia
3
– Export subsidies: EU, China– Restriction on government procurement of foreign
products: USA (e.g. on Mexican trucks resulting in retaliation)
Competitive currency depreciation:– Keeping down the value of pound sterling hurt Irish
mfg– Switzerland weakened franc to support exports– Chinese currency considerably undervalued
• This strategy works for a few smaller countries • But not for the world as a whole: someone has to
import if others want to export (Krugman’s comment: export to Mars?) 4
Fallacy of Composition (will refer to this again in Adding-up Problem)
FX reserves:
China: $ 2 trillion
Russia: $ 600 billion
India, South Korea: $250 billion
• For ‘self-insurance’ against a rainy day
Q. Why is it called ‘self insurance’?
G-20 April 2009 Summit
• Pledged to refrain from competitive devaluation of currencies
So multilateral cooperation needed
Alternative: boost domestic demand
5
Adam Smith (Absolute Advantage) 1776
(DS, 33-35)
Refuted mercantilism
Advocated:
– laissez-faire
– free trade based on specialization
Canada Wheat
Nicaragua Bananas
Q. What is a banana republic?
1991: Some observers said that India was almost a banana republic
October 2013: USA (not trade-related).
6
Canada is more efficient than Nicaragua in producing wheat and vice versa in bananas
Production vs. Productivity
Higher production does not mean higher productivity:• Production will be more if more land or labour is used. • Productivity (i.e. production per hectare or per man-hour)
measures efficiency.
7
DS Table 2.1
Output / man-hour
( or Labour Productivity)
US UK
Wheat (bushels) 6 1
Cloth (yds.) 4 5
Q. Why man-hour and not number of workers?
Q. US is more efficient than UK in the production of________
UK is more efficient than US in the production of_________
8
Q. US has absolute advantage in _________UK has absolute advantage in _________
Gains from Specialization and Trade
US gains if 6W exchanges > 4CSuppose it exchanges at 6W = 6C.Gain to US is:____ (i.e. ____ labour time)
UK Domestically 1W = 5C, i.e. 6W = 30C Trade with US 6W = 6CSaves ____ (i.e. about __ man-hours)
9
Review Questions
Q. Adam Smith _______ (opposed / supported) mercantilism. Explain your answer.
Q. Efficiency is measured by labour productivity (LP). LP is defined as production (i.e. output) per labour hour.
• Why is efficiency measured by productivity and not production?
• Why is output divided by number of hours worked and not number of workers?
10
Comparative Advantage (Ricardo 1817)(DS 35-37)
Lawyer-secretary example
Table 2.2Output / man-hourUS UK
Wheat (bushels) 6 1Cloth (yds.) 4 2
US is more efficient than UK in bothIn wheat: _____ timesIn cloth: _____ times
11
_______ has absolute advantage in both wheat and cloth_______ has absolute disadvantage in both wheat and
cloth
US has greater absolute advantage in wheat (6:1) than in cloth ( )
Therefore, US has comparative advantage in wheat
UK has lower absolute disadvantage in ______ ( ) than in ______ ( )
Therefore, UK has comparative advantage in ______
12
Gains from Specialization and Trade
US should specialize in _________
UK should specialize in _________
Domestically in US 6W = 4C
in UK 1W = 2C or 6W = 12C
US gains only if it gets > 4C for 6WUK gains only if it has to give < 12C for 6W
The range for mutually advantageous trade is:4C < 6W < 12C
13
Suppose they exchange at 6W for 6C
US gets domestically 4C for 6WIn trade, it gets 6CSo it gains ________ or ______ man-hours
UK domestically has to give 12C to get 6W. In trade it gives only 6C.
So it saves ________ or_______ man-hours
Q. Compute the gains to both if they exchange at6W = 8C
14
Economic Theory as a Political Instrument(K-O)War with France –
1789 French Revolution to 1815 (battle of Waterloo)Napoleon’s comment: nation of shop-keepers
Q. Britain: exporter of ______ (Mfs / ag. products) Why?
Blockade on trade
Q.Relative prices of food in UK _______(increased /decreased)
Q. After war, food prices fell in Britain. Why?
15
Influential landowners got Corn Laws passed
Ricardo (London businessman) – argued for:– repeal of Corn Laws– free trade to end tariffs on food imports
Corn Laws Repealed: 1846 (Ricardo died in 1823)
Thomas Hardy
Mayor of Casterbridge(Novel first published in 1886)
One of the events that formed the basis for the novel:– The uncertain harvests which immediately preceded
the repeal of the Corn Laws

Review QuestionsTable 2.2
Output / man-hourUS UK
Wheat (bushels) 6 1Cloth (yds.) 4 2
Q. In which product has India comparative advantage and why?
Q. If the exchange rate between the two countries is
6W = 10C, compute the gains for each country in terms of quantity and time saved .
Q. If the exchange rate between the two countries is
6W = 12C, which country won’t be interested in trade and why?
Q. The average productivity of labour in Japanese manufacturing in 1990 was 20 percent lower than labour productivity in the US. But in automobiles and auto parts industry Japanese productivity was 16 to 24% higher than American productivity. From this it can be inferred that Japan has _______ (absolute / comparative) advantage in automobiles and parts. Explain your answer.
Q. (Hypothetical, not actual): The average productivity of labour in Japanese manufacturing in 1990 was 20 percent lower than labour productivity in the US. But in apparel industry Japanese productivity was 16 percent lower than American productivity. From this it can be inferred that Japan has _______ (absolute / comparative) advantage in apparel. Explain your answer.

Case Study – Germany
ULC• Labour cost / Output = w /LP
After reunification in 1990, ULC increasedQ. Why referred as ‘reunification’?Q. Higher wage rate (why?)Q. Lower productivity (why?)
– Exports declinedLater, exports increased
20
• Threat of firms moving to central or eastern Europe held wage rates in check
• LP was boosted through training
IHT, 4 August 2010
Exports helped by:– Resisting rise in wages
• Trumpf, a German machine tool mfr, laid off 90 out of 650 in the US
• But no lay off of 4,000 in Germany• Short work (i.e. reduced hours, 85% salary, no
layoffs)– Skill development in spare time

Q. Among the four which is most competitive? Why?
22
Factor-proportions Theory or Factor-endowments Model or H-O Theory ( Heckscher 1919, Ohlin 1933)
(S-S)
Adam Smith – Absolute advantage
Ricardo - Comparative advantage
(based on efficiency – or productivity of labour)
Source of this efficiency: not explained – Why is it that US has comparative advantage in
machinery?– Why is it that India has comparative advantage in
cloth?
US is K-abundant, machinery is K-intensive. Since K is cheaper in US, it can produce machinery cheaper.
23
India is L-abundant, cloth is L-intensive . Since___ is cheaper in India, it can produce cloth cheaper.
Formal explanation:US is K-abundant
1992 $
K / L in US 35,993K / L in India 1,997
Q. Why ratio?(r / w) in US ____ (> or <) (r / w) in India or(w / r) in US ____ (> or <) (w / r) in India
Q. Why ratio? 24
Table 3.1Machine production: more K- intensive both in the US and India compared to cloth production:
K / L ratio in machines ______ in cloth ______
• Machines are more capital intensive in both countries.• But K-intensity is same in both countries for each
product
Q. In reality, for each product, will the ratios be equal in the two countries?In which country do you expect them to be higher?
25
FP or H-O Theorem: A country will have comparative advantage in goods whose production intensively uses its relatively abundant factor of production
Factor-Price Equalization Theorem (H-O-S) Theorem
(S – S)
As trade opens, industrial structure changes.
US: demand for machines goes ____ (up / down)
- price of machines goes ____
- Demand for K goes _____ (up / down) (Derived demand)
- r goes up– Vice versa for cloth: w goes down
26
India – opposite: w/r goes up
(w/r) in US tends to converge to (w/r) in India
Lesson for MNCs • Investment decisions are based on wage differentials. • But FPE will erode that advantage
Trade Adjustment Assistance (USA)
(S-S)
Samuelson – compensate labour
US – TAA since 1962 for L displaced due to imports
2001: $407 million
Q. TAA is by nature discriminatory – why?
27
Wage inequalities in US
(DS, p.135) 1995
Tech. change 38%
Int. trade 10%
28
Product Cycle
(DS, 179-181)
Vernon (1966)
Innovation, technology and high-skilled L: new product
Product standardised: mass production with less-skilled labour
Comparative advantage: shifts from developed to developing countries
(+ FDI flows)
Example: Post II War
US firms – dominated in radios (using vacuum tube)
Japan copied US tech. and used cheap labour
29
US introduced transistors and then printed circuitsBut comparative advantage shifted to Japan
Stage I: New product phase ( domestic sales)Stage II: Product-growth phase (exports)Stage III: Product-maturity phase (standardised – licensed
to other countries)Stage IV: Price competition, not brand competitionStage V: Imitating country – exporter Innovating country - importer
PC model - extension of the basic H-O model in a technologically dynamic world, not an alternative trade model
30
– HO model: L and K are factors– New factor: Technology - Relative factor abundance
(technology) in industrialised countries
Basic H-O model - explains static comparative advantage
PC model – explains dynamic comparative advantage
Recent years:• Diffusion lag shortened• Innovating countries need to act faster
“The United States must run faster and faster to avoid falling behind”
Q. This is similar to which famous statement? 31
Bhagwati: Kaleidoscopic Comparative Advantage
Q. ‘Geography is history’: what does this mean in the context of what Bhagwati said in this paragraph?
The world is flat – there is no comparative advantage left.
Bhagwati counters this argument:• Educated manpower in India
– Only 6% make it to college• Of these, two-thirds graduate• Just a small fraction speak English
• China and India have lower wages
32
• But US has:– Better infrastructure– Stronger VC markets– Culture of inventiveness
• i.e. comparative advantage persists
Kaleidoscopic Comparative Advantage• E.g. Boeing – Airbus – Boeing• ‘The proper response to flux is to manage it.’• Strengthen Adjustment Assistance Programmes.
Examples: – Aeronautical to automobile engg. – General engineering skills than specialized ones– Radiologists – cosmetic surgery
33
IITS-S
H-O: Interindustry trade - mostly between developed and developing countries
IIT: between developed countries – e.g. cars, based on product differentiation
IIT index = 1 – [IX-MI / (X + M)]
Industry USA_________Machines X=$1m M=0 I = 0Cloth X=0 M=$1m I =___Food X=$50,000 M=$50,000 I =___
34
I.e. The index lies between 0 and 1
Industry Dresses
US exports $100,000 (women’s) dresses imports $100,000 (men’s) dresses I = ____
Women’s DressesUS X=$100,000 M=0 I =_____
Men’s DressesUS X=0 M=$100,000 I =_____
35
Q. The more broadly we define an industry / product group, the _____ (higher / lower) will be the value of IIT index.
Other examples: Computers and parts; automobiles and parts
IIT in Homogeneous GoodsCement : Transport costServices: Transport, insurance and financial services– US exports computers to Germany &
imports automobiles from Germany : inter-industry trade
– Related services : IIT
36
Entrepot tradeOnly storage and distribution
(Singapore)Re-export trade
Small transformation – import, sort, re-pack, label, and export(Singapore, HK-SAR, and the Netherlands)
IIT in Differentiated Products• Horizontally differentiate products: Candy bars
Have same price, but different flavours and ingredients
• Vertically differentiated products: automobilesWide variation in prices and physical characteristics
37
Monopolistic competition
Women’s clothing
Oligopoly
Automobiles, TVs, tires
38
Tariffs and ERP
(Carbaugh)
Q. Normally countries impose higher tariffs on imports of ______ (inputs / final product). Why?
Q. Examples?
Nominal and effective tariff rates
Import of radio
$
Free trade price of radio 100
Nominal tariff on radio 10
Price incl. tariff 110
(No tariffs on radio parts)
39
Incidence on consumers 10% ($10 tariff on import price of $100)
Domestic Competing Radio
Tariff on RadioNil 10%
Imported parts 80 80
Domestic value added
(assembly cost) 20 30
Total 100 110
(No tariffs on radio parts)
Under protection, assembly cost can be $30 instead of $20 to compete with imports. The producers can afford $10 extra cost than under free trade. The extent of protection is: $10 /$20= 50%
40
Nominal tariff: 10%
Effective tariff: 50%
Q. While the nominal tariff rate is important to consumers, ERP is important to producers – Explain
Q. The tariff is imposed on inputs is nominal tariff, while the tariff imposed on final products is the effective tariff. What is wrong with this statement?
Duty on Imported Parts
Q. If you are a producer of radios:• what is your preference: tariff on radios or parts?• If there is, say, 5% nominal tariff on parts, ERP to you is
higher or lower than before (i.e. when no tariffs on parts)
41
Formula for ERP:
e =
n – ab
1 – a
n = 10%, a = 80%
Q. If b = 0%, e = ______
Q. If b = 5%, e = less or more than above?
Q. If b = 20%, e = _______
Q. As a producer of radios, you want tariffs to be higher for: radios or parts?
Inverted duty structure: negative effective protection
42
Case Study: Tyres and Natural Rubber(Economic Times, 12 August 2012)
Import Duties(%)
Tyres 10%
Natural Rubber 20%
43
Regional Economic Arrangements
(SS)
WTO consistency
Q. Why inconsistent?• Notify WTO• Substantial coverage• Not to raise trade barriers to non-members, i.e. TC
should be > TD (see p.188)
Substantial coverage• Only non-ag. products, e.g. EU-Israel, EU-Turkey • All merchandise• Trade in G and S, FDI, portfolio investment, e.g. NAFTA
44
Degrees / Levels of Economic Integration
PTA - positive list
FTA
Q. Examples?• Negative list• Trade Deflection
– US, Mexico, Japan 4% and 20%• RoO
– To avoid trade deflection– Min. VAD 62.5% for cars in NAFTA
CU: FTA + CET• Harmonization or phasing in - about 15 years• Coverage more comprehensive than FTA
45
CM: CU + free movement of L and K
Advantages and disadvantages
EU: CM + some degree of unification in economic policies
Q. Example of a common target for an economic policy?
TC and TD
Fig. 9.1, p188
Mexico substitutes more efficient US cars for less efficient Mexican cars: TC
Mexico substitutes less efficient US cars for more efficient Japanese cars: TD

International Trade and Economic Development
(DS)Trade as Engine of GrowthQ. In recent years, this concept was applied to which
countries / region?1815 to 1913 • Britain’s GNP increased 10 timesDue to increase in industrial productionQ. Why?• Rising demand for food and raw materials (imports
increased 20 times)• Exports of ‘regions of recent settlement’ to Britain
increased• Helped their growth through ‘accelerator-multiplier’
process.• That is, trade acted as engine of growth (One economist
– Nurkse) 47
Q. ‘Trade as engine of growth’ concept applies to Britain or regions of recent settlement?
Another Economist (Kravis)
The regions of recent settlement were:• Richly endowed with natural resources• Inflow of capital and skilled labour
– Built good local transport facilities• Improvement in sea transportation
So:• Growth was due to favourable internal conditions• Trade played a supportive role (handmaiden)Now (developing countries)Demand side:• Low income elasticity of demand
48
• Synthetic substitutes• Tech advances• Growth of demand for services• Trade restrictionsSupply side:• Less endowed with natural resources• Over population• Less inflow of capital• Outflow, not inflow, of skilled labour• Neglect of agriculture
Case Study: Asian Miracle (DS, p. 362)• Supports handmaiden version – exports, high S and I
rates, education and training, technology, etc. caused high growth
49
Terms of Trade
(DS, 11.3 A)
Commodity or Net Barter ToT (or simply ToT)
N = (Px / Pm) x 100
Income ToT or purchasing power of exports or export-based capacity to import
I = [(Px x Qx) / Pm] x 100
ToT of Developing Countries
Commodity Terms of Trade
Prebisch-Singer Hypothesis: secular decline 1870 - 1938
50
ToT depend on type of products exported and their price trends
• 1972 – 2001: ToT of raw materials exporters increased
Income Terms of Trade of Developing Countries (1953-1983)
• 20% decline in commodity ToT• But 165% increase in income terms of trade
Q. What is the inference?
UN (2012), Figure II.6 ToT• Oil exporters: sharp rise till 2008 and wide fluctuations
thereafter• Minerals: Rise after 2011 due to rising prices of precious
metals because of economic uncertainty• Manufactures exporters: decline

Services Modes
1 Cross-border supplye.g. international telephone calls
2 Consumption abroade.g. tourism
3 Commercial presencee.g. foreign banks setting up operations in

e.g. fashion models, consultants , software engineers
Q. Why called ‘natural’ persons?
61
FlexibilityMFN exemptions
Commitments + list of services already covered under bilateral or regional agreements
Market-access commitmente. g. foreign banks can operate in domestic market
Market access limitatione. g. on number of branches
Exception to national treatmente. g. less number of branches for foreign banks than domestic banks
Government services: exemptSector-by-sector
Commitments not required on whole set of services sectors
2001: Made part of ‘Single Undertaking’ 62
TRIPSPatents, trade marks, copy rights, etc.
1995: CL already in TRIPs• Doubts expressed by developing countries in
implementation
2001: Separate Declaration on TRIPS and Public Health• CIPLA case (Paragraph 4)• Paragraph 6: In case of no mfg capacities
2003: “Waiver’ adopted by the General Council
2005: Endorsed the Amendment to TRIPS AgreementQ. Why was this needed?
63
Cases
India’s generic drugs (BS, Jan. 23, 2012)• Goods in transit seized by EU countries on grounds of
infringing IPR• India to approach DSB• EU promises to settle the issue during bilateral talks
Natco’s cancer drug (BL, 13 March 2012)• First CL• 6% royalty to Bayer• Bayer price: Rs. 2.8 lakhs per a month’s supply• NATCO price: Rs. 8,800
64
Novartis’ cancer drug (BL, 13 March 2012)• Evrergreening• Supreme Court verdict awaited
65
Contingent Protection (ADD, CVD, Safeguards)
Dumping: export price below ‘normal value’
Normal value:– Price in exporter’s domestic market– Export price in another country– Production costs + normal profits
ADD allowed if:– Show that there is dumping– Calculate the extent of dumping– Establish ‘material’ or ‘serious’ injury
Sunset clause: normally 5 years
66
Subsidies
Dumping: action by a company
Subsidies: action by government
Subsidies hurt:– Domestic industry in the importing country– Rival exporters in a third country– Other country exporters competing with domestic
products
Injury test and sunset clause
Exemption: LDCs and developing countries with < $1,000 per capita GNP
67
Safeguards: if there is ‘surge of imports’
Already there under GATT, but were ‘grey’– Voluntary export restraints, e.g. automobiles, steel,
T&C – Injury test and sunset clause (4 years)
Q. Why called ‘contingent’?
Q. Difference between this and regular tariffs?
