Introduction:
International Trade :
International trade is the exchange of goods and services between countries. This type of trade givesrise to a world economy, in which prices, or supply and demand, affect and are affected by globalevents. Political change in Asia, for example, could result in an increase in the cost of labor, therebyincreasing the manufacturing costs for an American sneaker company
International trade theory is based on the principle of comparative advantage which is in turn basedon the concept of opportunity cost.
Opportunity Cost:
Opportunity cost is the cost of any activity measured in terms of the value of the best alternativethat is not chosen (that is foregone).

Difference Between Domestic Trade And
International Trade
Domestic Trade International Trade
Domestic trade, also known as internal trade or hometrade, is the exchange of domestic goods within theboundaries of a country. This may be sub-divided intotwo categories, wholesale and retail.
International trade is the exchange of capital, goodsand services across international borders orterritories.
Domestic business pertains to a limited territory.Though the firm has many business establishmentsin different locations all the trading activities areinside a single boundary.
Scope of international business is quite wide. Itincludes not only merchandise exports, but also tradein services, licensing and franchising as well asforeign investments
Domestic business is conducted locally so there isno involvement of foreign currency.
International business nations gain by way of earningforeign exchange, more efficient use of domesticresources,
The main difference is that international trade istypically more costly than domestic trade

Explain Motivation For And Advantage Of Trading Blocs,
Common Market, And Economic Unions
A trade bloc is a type of intergovernmental agreement, often part of a regional inter governmentalorganization, where regional barriers to trade, (tariffs and non-tariff barriers) are reduced or eliminated
among the participating states.
Reduction in Trade restriction have positive effect result from increased trade according tocomparative advantage as well as increase in competition
The negative effect result because some firms, some industries, some group of worker will see their
wealth and income decrease. Worker in affected industries may need to learn new skills to get newjobs.

Comparative Advantage And Absolute Advantage
Absolute Advantage: A country is said to have an absolute advantage in the production of a good if itcan produce the good at lower cost in terms of resources than that of another country
Comparative Advantage: A country is said to have Comparative advantage in the production of agood if its opportunity cost in terms of other goods that could be produced instead is lower than that ofanother country
Even if a country does not have an absolute advantage in the production of any good, It can gain from
trade by producing and exporting the goods by which it has comparative advantage and importinggoods in which it has comparative disadvantage.

Comparative Advantage And Absolute Advantage
The law of comparative advantagesays that two countries (or other kinds of parties, such asindividuals or firms there as) will both gain from trade if, in the absence of trade, they have different
relative costs for producing the same goods.
Even if one country is more efficient in the production of all goods (absolute advantage) than theother, both countries will still gain by trading with each other, as long as they have different relativeefficiencies.
For example, if, using machinery, a worker in one country can produce both shoes and shirts at 6 perhour, and a worker in a country with less machinery can produce either 2 shoes or 4 shirts in an hour,each country can gain from trade because their internal trade-offs between shoes and shirts aredifferent.
The less-efficient country has a comparative advantage in shirts, so it finds it more efficient to produceshirts and trade them to the more-efficient country for shoes.

Ricardian And Heckscher- Ohlin Models Of Trade And
Sources Of Comparative Advantage
The Ricardian model assumes that labor is the only primary input to production (labor is consideredto be the ultimate source of value)
The Ricardian model focuses on comparative advantage, perhaps the most important concept ininternational trade theory.
In Ricardian model of trade, comparative advantage and pattern of trade are determined by differencein technology between country. In H - O model of trade, comparative advantage and the pattern of
trade are determined by difference of factor endowment between countries .
In a Ricardian model, countries specialize in producing what they produce best, and trade occurs dueto technological differences between countries. Unlike other models, the Ricardian framework predictsthat countries will fully specialize instead of producing a broad array of goods.
The main advantage of Ricardian model is that it assumes technological differences between
countries. Technological gap is easily included in the Ricardian and Ricardo-Sraffa model.

The Heckscher-ohlin Model (H-O Model) Makes
The Following Core Assumptions
Assumptions of H-O model:
Labor and capital flow freely between sectors
The amount of labor and capital in two countries differ (difference in endowments)
Free trade
Technology is the same among countries (a long-term assumption)
Taste and preferences are the same.
The problem with the H-O theory is that it excludes the trade of capital goods (including materials andfuels). In the H-O theory, labor and capital are fixed entities endowed to each country. In a modern
economy, capital goods are traded internationally. Gains from trade of intermediate goods areconsiderable, as emphasized by Samuelson .

Heckscher-ohlin Model And Its Assumption
In the early 1900s an international trade theory called factor proportions theory was developed by twoSwedish economists, Eli Heckscher and Bertil Ohlin. This theory is therefore called the Heckscher-
Ohlin theory (H-O theory).
The H-O theory stresses that countries should produce and export goods that require resources(factors) that are abundant and import goods that require resources in short supply.
It differs from the theories of comparative advantage and absolute advantage since those theories
focus on the productivity of the production process for a particular good. On the contrary, the H- Otheory states that a country should specialize in producing and exporting products that use the factorsthat are most abundant, and thus are the cheapest to produce.
The Heckscher-Ohlin model was produced as an alternative to the Ricardian model of basiccomparative advantage. Despite its greater complexity it did not prove much more accurate in itspredictions. However from a theoretical point of view it did provide an elegant method of incorporating
the neoclassical price mechanism into international trade theory.

Compare Type Of Trade And Capital Restrictions And
Their Economic Implication
A trade restrictionis an artificial restriction on the trade of goods between two countries. It is theresult of protectionism. However, the term is not uncontroversial since what one part may see as a
trade restriction another may see as a way to protect consumers from inferior, harmful or dangerousproducts.
There are many reason why government impose trade restriction. Some have support amongeconomist as conceivably valid in terms of increasing a countrys welfare, while other have little or no
support from economic theory.
Capital Restriction: It is defined as control placed on foreigners ability to own domestic assets and
domestic residents ability to own foreign assets. Thus , in control with trade restriction, which limit theopenness of goods market, capital restriction limit the openness of the financial market.

Balance Of Payment Account
Balance of payment account (BOP) is the account of a country
It is record of transactions of residents of country with rest of world.
It records payments and receipts from rest of world
Any transaction giving rise to payment is deficit (negative) e.g. purchase of property in USA, imports
Any transaction giving rise to receipt is credit (positive) e.g. exports, gifts from outside
BOP equation must satisfy all the time, which is
Current A/c + Capital A/c + net reserves = 0
16
Accounts in BOP
Current account Records trade in goods and services, transfer
payments, profits and interests earned on assetsabroad less profits and interests earned by foreignerson assets in our country
Capital account (financialaccount)
Records transactions in financial assets and land e.g.bond, stocks
Official settlement

Explain How Decision By Consumers, Firms, And
Government Influence The Balance Of Payment (Cont.)
Low private saving and high investment trend to produce a current account deficit that must
be financed by net capital imports, high private saving and low investment, however produce a
current account surplus, balanced by net capital exports.
A govt. deficit produce a current account deficit and a govt. surplus lead to current account
surplus.
In equilibrium, we have the relationship :
Export- Import = Private Saving + Govt. SavingDomestic investment
Lower level of private saving, Larger govt. deficit , and high rate of domestic investment all
tend to result in or increase a current account deficit. When total saving is less than domestic
investment, export must be greater than import so that there is a deficit in the current account.
Low private or govt. saving in relation to private investment in domestic capital requires foreigninvestment in domestic capital.

Nominal exchange rate (FX)
Amount of currency that is required to buy one unit of other currency
Price of one currency in terms of another
Example, Assume nominal exchange rate between Indian rupee and US dollar is 45 Rs per $ (Rs/$)
i.e. to purchase 1 $ we need Rs 45 Exchange rate can be expressed any way i.e. either Rs/$ or $/Rs
Numerator currency expresses the price of one unit of denominator currency

Real Exchange Rate
Real exchange rate:
Focus shifts to purchasing power of currency
Quantity of real goods an services that currencies can actually purchase
Real exchange rate (REER) = Nominal exchange rate * ( Price in country A / Price in country B )
Where, Nominal exchange rate = Currency of country B / Currency of country A
It is the ratio of foreign to domestic prices measured in the same currency
Rise in REER (depreciation of domestic currency) implies that foreign goods have become expensivethan domestic goods
REER = 1 implies that a good costs same in both countries taking nominal exchange rate in account Let, Nominal exchange rate (FX) = 45 Rs/$, Price of shirt in USA = 15$, Price of shirt in India = Rs 500
REER = 45 * (15 / 500) = 45 * ( 3/100) = 135/100 = 1.35
It costs 35% more to purchase same shirt in USA than in India
It requires $1.35 to purchase a good in USA that can be purchased for 1$ (in Indian rupees) in India atcurrent nominal exchange rate

Spot And Forward Markets For Foreign Exchange
Spot FX markets
It is the currency exchange rate for immediate delivery, which for most currencies means the exchange of
currency takes place two days after the trade. Transactions that had to be settled immediately like trading of equity
Settlement period is two business days after trade
Forward FX markets
Transactions that will be settled in future
Exchange of currencies takes place in future at the exchange rate agreed today
Forward contracts are generally for 30,60,90 and 180 days
Allows the firm to hedge against exchange rate uncertainty or fluctuations
Forward rate can be greater or less than spot exchange rate
Forward exchange rate represents the interest differential between two countries

Foreign Exchange
Appreciation of currency
When it requires less of domestic currency to purchase 1 unit of foreign currency
Example, FX decreasing from 46 Rs/$ to 40 Rs/$ Reduces the demand of domestic currency
Increases supply of domestic currency
Increases imports as foreign products become cheaper in international market
Domestic consumers demand more of foreign products
Depreciation of currency
When it requires more of domestic currency to purchase 1 unit of foreign currency
Example, FX increasing from 46 Rs/$ to 50 Rs/$
It raises the demand of domestic currency
Decreases supply of domestic currency
Increases exports as domestic products become cheaper in international market
Foreigners demand more of domestic currency

Exchange Rate Quotes
Two kind of quotes
Direct quoteA foreign exchange rate quoted as the domestic currency per unit of the foreign currency. In other words,it involves quoting in fixed units of foreign currency against variable amounts of the domestic currency.
Price of one unit of foreign currency in terms of domestic currency
Exchange rate of 46 Rs/$ is a direct quote for Indian citizen
It tells the value of 1 unit of foreign currency in terms of domestic currency to domestic resident
Value of foreign currency is fixed at 1 and value of domestic currency is variable Domestic currency per unit of foreign currency
For example, in the U.S., a direct quote for the Canadian dollar would be US$0.85 = C$1. Conversely,in Canada, a direct quote for U.S. dollars would be C$1.17 = US$1.

Exchange Rate Quotes
Indirect quote
A foreign exchange rate quoted as the foreign currency per unit of the domestic currency. In an indirectquote, the foreign currency is a variable amount and the domestic currency is fixed at one unit.
Price of one unit of domestic currency in terms of foreign currency
Exchange rate of 46 Rs/$ is a indirect quote for US citizen
It tells the value of 1 unit of domestic currency in terms of foreign currency to domestic resident
Value of domestic currency is fixed at 1 and value of foreign currency is variable
Foreign currency per unit of domestic currency
For example, in the U.S., an indirect quote for the Canadian dollar would be C$1.17 = US$1.Conversely, in Canada an indirect quote for U.S. dollars would be US$0.85 = C$1
To convert an indirect quote to direct quote
Take the reciprocal of exchange rate
Example Indirect quote 46 Rs/$ for US citizen
Direct quote 1/46 $/Rs = 0.0217 $/Rs for US citizen

www.edupristine.com Neev Knowledge Management Pristine
To Another Currency
For a change in an exchange rate, we can calculate the percentage appreciation (price goes down) ordepreciation (price goes up) as the percentage change in the price currency.
For example, a decrease in the USD/ EUR exchange rate from 1.44 to 1.42 represents anappreciation of the USD relative to the EUR of 1.39% (1.42 / 1.441 = - .0139)
To calculate the appreciation or depreciation of the base currency, we first invert the quotes and thenproceed as the above example.

Example, let Rs/$ = 46 and $/GBP = 1.67then Rs/GBP = ( Rs/$ ) * ( $/GBP) = 46 * 1.67 = 76.82
Hence, Rupee - Pound cross rate is 76.82 Rs/GBP

Forward Discount And Premium
A forward premium or discount is calculated
Forward discount Assume INR/$
If forward price of INR/$ is greater than spot price of INR/$
Then, INR is quoted as forward discount
INR (domestic currency) is cheaper today than future
Forward premium Assume INR
If forward price of INR/$ is lesser than spot price of INR/$
Then, INR is quoted as forward premium
INR (domestic currency) is expensive today than future

Interest Rate Parity
Interest rate parity
Expected returns on deposit of two currencies should be equal when measured in same currency
Forward premiums and discounts wipe out the differences in interest rates between two countries If interest rates are higher in country A compared to country B, then currency of country A will depreciate
thus equating returns in both countries
Mathematically,
where F = forward rate; S = Spot rate; R = risk free interest in both countries
Forward and spot quotes are direct quotes to investor of country A i.e. B : A
Alternate mathematical representation
When interest rate parity holds
Higher (lower) nominal interest rate in country will lead to currency selling at forward discount (premium)
Simply put, IRP implies that interest rate differentials is equal to forward rate differential.

Purchasing Power Parity
Same good should cost equal in different countries considering the nominal exchange rate
REER should be equal to 1
Example, FX = 45 Rs/$, Price of shirt in USA = $15
then, in India Price of shirt should be = 15 * 45 = Rs 675
But the shirt in India is for Rs 500
This is due to many factors like taxes, subsidies, transportation costs etc
Nominal exchange rate (FX) should change such that REER becomes equal to 1
Therefore, FX * (15/500) = 1FX = 500/15 = 33.33 Rs/$

www.edupristine.com Neev Knowledge Management Pristine
Exchange Rate Regimes
Each country, through varying mechanisms, manages the value of its currency. As part of thisfunction, it determines the exchange rate regime that will apply to its currency. For example, the
currency may be free-floating, pegged or fixed, or a hybrid.
If a currency is free-floating, its exchange rate is allowed to vary against that of other currencies and isdetermined by the market forces of supply and demand. Exchange rates for such currencies are likelyto change almost constantly as quoted on financial markets, mainly by banks, around the world.
A movable or adjustable peg system is a system of fixed exchange rates, but with a provision for the
devaluation of a currency. For example, between 1994 and 2005, the Chinese yuan renminbi (RMB)was pegged to the United States dollar at RMB 8.2768 to $1.

Trade And Capital Flows.
Elasticity of export and import demand must meet the Marshall-Lener condition for a depreciation ofthe domestic currency to reduce an existing trade deficit.
Export - Import = (Private Saving - Investment in physical capital) + (Tax revenue - Govt. Spending)
The J curve :
Import and Export quantities may be relatively insensitive to currency depreciation in the short run.
Currency depreciation may worsen a trade deficit.
The short term increase in the deficit followed by a decrease when the Marshall- Lerner condition ismet is referred to as the J- curve.
Under the absorption approach, national income must increase
relative to national expenditure in order to decrease a trade deficit.
This can also be viewed as a requirement that national saving must
increase relative to domestic investment in order to decrease a trade deficit.

1. a. For 3 months
F3-months= S*(1.08/1.015)0.25 = 47.84
b. For 6 monthsF6-months= S*(1.08/1.015)
0.5 = 48.58
c. For 1 year
F12-months= S*(1.08/1.015)= 50.12
d. Let the forward rate in market for 1 year is 48 Rs per $. Yes there any arbitrage opportunity
2. Since the forward rate is trading at $1.65/GBP therefore the USD is trading at a forward discount tothe GBP. The annualized discount is 6.25%. Since the USD is trading at a forward discount it is theweaker currency in the exchange pair.
3. Since the USD is trading at a premium to the GBP in the forward market. The GBP risk-free rate isgreater than the USD risk-free rate
4. Given the bid-ask rates the USD:GBP cross rates are (USD:GBP)ask= 78.2/46.3 = 1.6890
(USD:GBP)bid = 78.5/46 = 1.7065

5. The following quotes are available at GNB
USD:INR = 45.13
GBP:USD = 1.5424GBP:INR = 70.02
Compute any arbitrage opportunity that may be available in the above case. Calculate the arbitrageprofit from $1,000
The cross rate for GBP:INR = 45.13*1.5424 = 69.61. Since the GBP:INR rate provided by GNB ishigher a triangular arbitrage is possible. Given 1,000 USD. A triangular arbitrage is possible throughthe following series of transactions
a. Convert USD to GBP
1,000 USD /1.5424 = 648.34 GBP
b. Convert GBP to INR
648.34 * 70.02 = 45,396.78 INR
c. Convert INR to USD
45,396.78/45.13 = 1,005.9 USD
Thus a profit of 5.9 USD is possible through a triangular arbitrage.
