11.  International Trade and International Finance


Patterns of U.S. Trade -
major exports - autos, computers, aircraft, ag. products, scientific instruments, coal, plastics

major imports - oil, autos, clothing, iron, steel, office machines, footwear, fish, coffee, diamonds

Why trade?  Just like individuals, different countries have different natural resources, labor conditions, skills.
Should we raise oranges in Ohio and not in Florida?

Individuals and countries trade for the same reasons-

-specialization and division of labor
-gains in efficiency and total output

Comparative advantage - country gains if it produces those products where it has the greatest relative advantage

-self sufficiency in expensive
-example, lawyer who can type well hires secretary to type
-absolute advantage vs. comparative advantage

Graphic Models of comparative advantage

-production possibilities curve
-terms of trade (i.e., relative prices)

A

Before Trade:
Opportunity cost
Eastern Ohio 1 cord Wood = 1/2 bu. Corn
Western Ohio 1 cord Wood = 2 bu. Corn

B

Assumption:
Trade occurs with exchange at 1 cord Wood = 1 bu. Corn

Arguments for trade
  • Accommodates differences between resource endowments and tastes - consumers and producers gain.
  • Economies of size gives advantage to global companies
  • Promotes competition
  • Interdependence of nations
  • Must be buyers as well as sellers
Arguments against trade
  • Lost jobs and profits
  • Dependency on critical import - national defense
  • Unsafe products
  • Quid pro quo - one thing in return for another
  • Infant industry
  • Destruction of culture
Trade protectionism
  1. Non-tariff barriers
  2. Tariffs
  3. Quotas
  4. Subsidies to producers
  5. Voluntary export (import) restraints
Move toward freer trade
General Agreement of Tariffs and Trade (GATT)
World Trade Organization (WTO)
Regional Agreements
N. Amer. Free Trade Agreement (NAFTA)
Free Trade Area of the Americas (FTAA)
Bilateral Agreements

International Finance

1.

Balance of Payments - periodic statement of money value of all transactions between one country and another.

Transactions

-supplying country's currency - Debit (-)
     (e.g., buying coffee from Brazil)
-demanding country's currency - Credit (+)
     (e.g., selling corn to Japan)

2.

Components of balance of payments

a.

Current Account - payments related to goods and services
  • Exports of goods and services (Credit)
  • Merchandise Trade Balance
  • Imports of goods and services (Debit)
  • Net Unilateral Transfers (Debit, if sending money abroad)
  • Current Account Balance

b.

Capital Account - payments related to assets and debt
  • Inflow of Capital (Credit)
  • Outflow of Capital (Debit)
  • Capital Account Balance

c.

Official Reserve Account - changes in govt. holding of gold, foreign currencies, reserve position in Int'l. Monetary Fund
  • Decrease (Credit)
  • Increase (Debit)
d. Balance of Payments = Current Account

   + Capital Account
   +Official Reserve Account
   +Statistical Discrepancy

=0

Currency Exchange
Flexible Exchange Rates vs. Fixed Exchange Rates
Exchange Rate - conversion rate of one currency to another
Exchange Rates from WSJ
Demand for and Supply of Currencies
- Determined by Balance of Payments Forces
- At equilibrium exchange rate, demand for currency (credits) is equal to
    supply of currency (debits)
Supply and Demand Diagrams - Supply of U.S. dollar equal to Demand for British pound (Exhibit 20-5)

Changes in Equilibrium Rate, ceteris paribus

  1. Changes in National Income - increase in foreign purchases (imports) causes home country currency to depreciate
  2. Inflation - increase in country's inflation rate will cause home country currency to depreciate
  3. Real interest rates - decrease in real interest rate will cause currency to depreciate
In equilibrium, supply and demand for currency are in balance
- there is no surplus or deficit in balance of payments account
In disequilibrium, then either
  1. Supply of currency exceeds demand, and
       - currency is "overvalued"
       - something must be done to remove surplus from market or
       - black market develops
  2. Supply of currency less than demand, and
       - currency is "undervalued"
       - something must be done to provide currency for market
Fixed exchange rates = governments agree on constant exchange rate, and exchange rate is not allowed to "float"

Persistent imbalances

- what might govt. do to maintain fixed rate?  
     options:  affect income, inflation, real interest
History of Exchange Rates (since mid 1800s)
Gold Standard
-define value of currency in terms of ounces of gold
-convert currency to gold and vice versa
-link available money supply to gold

Bretton Woods System (1944-71)
-fixed exchange rates
-countries would buy and sell currencies to maintain rates
-International Monetary Fund - countries could borrow currencies to finance purchase and sales

Managed flexible exchange rates (1971-  )
-floating exchange rates
-central banks intervene to manipulate rate sometimes
-smaller countries "peg" their currencies to a larger country's
