LECTURE
Balance of Trade (BOT)
Balance of trade: the difference between exports and imports (Xn)
Includes goods and services
Balance of Trade (BOT) The U.S. has a trade deficit—importing more than it is exporting
In 2018, the U.S. trade deficit (goods only) was $810 billion
It imported $2.3 trillion of goods and services while exporting $1.5 trillion
65% of our trade deficit is due to trade with China (second largest is Japan, third largest is Germany)
The U.S. is financing its trade deficit by selling off assets
Balance of Payments (BOP)
Balance of payments: is a country’s record of all transactions between its residents and the residents of all foreign nations
A credit is a foreign payment to the U.S.
The U.S. earns a supply of foreign currency
A debit is a U.S. payment to another country
The U.S. uses its reserves of foreign currency to purchase goods; the country the U.S. is purchasing goods from earns reserves of U.S. dollars
Balance of Payments (BOP)
A deficit in the balance of payments occurs when the U.S. is paying out more for foreign goods, services, and investments than it is receiving
The U.S. is not earning enough foreign reserves to cover its purchases from foreign nations
Balance of Payments (BOP)
A surplus in the balance of payments occurs when payments to the U.S. are greater than U.S. payments to foreign nations
The U.S. is earning more in foreign currencies than it is using to purchase foreign goods, services, investments
Balance of Payments (BOP)
Goods exported by the U.S. must be paid for in U.S. dollars
Exports cause a flow of payments into the U.S.
Goods imported by the U.S. must be paid for in foreign currency
Imports cause a flow of dollars outside the U.S.
Balance of Payments (BOP)
Includes two accounts:
The current account and the financial (capital) account
The Current Account
The current account is made up of three parts:
1. Net Exports: Difference between a nation’s exports of goods and services and its imports of goods and services
Examples: Toys imported from China; U.S. cars exported to Mexico
(We will use this one the most, especially in FRQs)
The Current Account
2. Investment Income: Income from the factors of production, including payments made to foreign investors
Example: Money earned by Japanese car producers in the U.S.
3. Net Transfers: Money flows from the private or public sectors
Examples: Donations’ aids and grants
The Financial Account
The financial (capital) account measures the purchase and sale of financial assets abroad
Includes purchases of things that stay in the foreign country such as financial assets (stocks and bonds) and real estate
Examples: A U.S. citizen buys German stock; a U.S. company buys a hotel in Russia
The Current Account and the Financial Account
The current account balance and the financial account balance must equal zero
When they do not, the central bank must buy or sell currency (known as official reserves—government holdings of foreign currencies) to resolve this imbalance
The Current Account and the Financial Account
When the current account is in a deficit it is due to importing more goods and services than it is exporting
Current account deficits must be offset by financial account surpluses
Increasing current account deficits means that capital inflows increase (this increases the supply of loanable funds)
The Current Account and the Financial Account
When the current account is in a surplus it is due to exporting more goods and services than it is importing
Current account surpluses will be offset by financial account deficits
Current account surpluses means that capital outflows increase (this decreases the supply of loanable funds)
(Watch Mr. Clifford Video #1)
Sample Question Balance of payments accounts record all of a country’s
international transactions during a year.
a.) Two major subaccounts in the balance of payments accounts are the current account and the financial (capital) account. In which of these subaccounts will each of the following transactions be recorded?
(i) A U.S. resident buys chocolate from Belgium.
(ii) A U.S. manufacturer buys computer equipment from Japan.
b.) How would an increase in the real income in the U.S. affect the U.S. current account balance? Explain.
Answer:
(a). (i) Current account
(a) (ii) Current account
(b) The current account balance will decrease (move toward a deficit) because the increase in income causes imports to increase
Exchange Rates
Exchange rate: the rate at which one country’s currency can be traded for another country’s currency
It is determined by supply and demand in the FOREX market (foreign exchange market) where currency is bought and sold
Exchange Rates
In the FOREX market we only look at two countries/currencies at a time
Example: U.S. dollars and British pounds
We examine the price of one currency in terms of the other currency. Example:$2 = £1
The exchange rate depends on which currency you are converting
The price of one U.S. dollar in terms of pounds is
1 Dollar = £1/$2 = £.5
The price of one pound in terms of U.S. dollars is
1 Pound = $2/£1 = $2
Exchange Rates
What happens if you need more dollars to buy one pound (the price for a pound increases)?
Example: From $2=£1 to $5=£1
The U.S. dollar depreciates relative to the pound
Depreciation: the loss of value of a country's currency with respect to a foreign currency
More units of dollars are needed to buy a single unit of the other currency
The dollar is said to be “weaker”
Exchange Rates What happens if you need less dollars to buy one pound (the price
for a pound decreases)?
Example: From $2=£1 to $1=£4
The U.S. dollar appreciates relative to the pound
Appreciation: the increase of value of a country's currency with respect to a foreign currency
Less units of dollars are needed to buy a single unit of the other currency
The dollar is said to be “stronger”
FOREX Market Shifters
A country’s incomeChanges in a country’s prices (price level)The interest rate in a countryTastes and preferences
FOREX Market Shifters
Changes in relative incomes (resulting in more imports)
Example: U.S. growth increases U.S. income
The U.S. buys more imports
U.S. demand for pounds increases
Supply of U.S. dollars increases
Pound: appreciates
Dollar: depreciates
FOREX Market Shifters
Changes in relative price level (resulting in more imports)
Example: U.S. prices increase relative to Britain
U.S. demand for cheaper imports increases
U.S. demand for pounds increases
Supply of U.S. dollars increases
Pound: appreciates
Dollar: depreciates
FOREX Market Shifters
Changes in relative interest rates
Example: U.S. has a higher interest rate than Britain
British people want to put money in U.S. banks
Capital flow increases towards the U.S.
British demand for U.S. dollars increases
British supply more pounds
Pound: depreciates
Dollar: appreciates
FOREX Market Shifters
• Tariffs increase the price of imports and reduce the quantity of imports demanded
• The supply of a country’s currency decreases since the demand to buy foreign currency to purchase the imports decreases
Sample Questions
1. U.S. income increases relative to other countries. Does the balance of payments move toward a deficit or a surplus?
U.S. citizens have more disposable income
Americans import more
Net exports (Xn) decrease
The current account balance decreases and moves toward a deficit
Sample Questions
2. If the U.S. dollar depreciates relative to other countries does the balance of payments move toward a deficit or a surplus?
U.S. exports are desirable
U.S. exports more
Net exports (Xn) increase
The current account balance decreases and moves toward a surplus

Explaining the Graphs: The FOREX Market
As Europeans supply more euros to purchase U.S. dollars, the euro depreciates
As the demand for the U.S. dollar increases, the dollar appreciates
Explaining the Graphs: The FOREX Market
Which graph is correct?
Depends on what the FRQ asks you to graph.
In summary, if it helps you to graph both, do it (see next slide).
Also note, that both supply and demand moved in the same direction—this is a sign you did it correctly.

Sample FRQ
Assume that the real interest rate in both the U.S. and the European Union equals 4.5 percent.
a.) Assume that the real interest rate in the U.S. falls to 3.75 percent.
(i). How will the flow of financial capital between the U.S. and the European Union be affected? Explain.
(ii). Using a correctly labeled graph of the foreign exchange market for the euro, show how the value of the euro would change relative to the U.S. dollar in a flexible exchange rate system.
b.) Explain how the change in the value of the euro in part a.)(i) would affect the European Union's net exports.
a.) (i) Capital will flow out from the U.S. to the European Union countries. The higher interest rate in the EU attracts investment funds from the U.S.

How Monetary Policy Affects Exchange Rates
Monetary policy affects exchange rates in three ways:
1. Its effect on the interest rate
2. Its effect on income
3. Its effect on price levels and inflation
Changes in Interest Rates
Interest rates in the U.S. increase
Demand for U.S. interest-bearing assets increases
Demand for dollars to buy U.S. assets increases
The increase in the demand for dollars causes the price of dollars to increase
Changes in a Country’s Income or Prices
Income or prices increase in the U.S.
Imports increase
Demand for foreign currency to buy imports increaseswhich means the supply of the dollar increases
The increase in supply of the dollar causes the price of the dollar to decrease
How Monetary Policy Impacts Exchange Rates
All the effects of monetary policy on exchange rates move in the same direction
Expansionary monetary policy pushes a country’s exchange rates down
Contractionary monetary policy pushes a country’s exchange rates up

Direct Methods of Influencing Exchange Rates
Expectations, rumors, etc. cause fluctuations in exchange rates
To avoid the problems caused by fluctuating exchange rates, governments sometimes intervene to fix exchange rates by buying and selling its currency
If government buys its currency, it can increase its exchange rate
If government sells its currency, its value decreases
Alternative Exchange Rate Systems
Three exchange rate regimes are:
1. Fixed exchange rate where the government chooses an exchange rate and offers to buy and sell currencies at that rate
2. Flexible exchange rate where the determination of exchange rates is left totally up to the market
3. Partially flexible exchange rate where the government sometimes buys or sells currencies to influence the exchange rate, while at other times letting private market forces operate
Advantages and Disadvantages ofFlexible Exchange Rate Systems
Advantages
They provide for orderly incremental adjustment of exchange rates
They allow government to be flexible in conducting monetary and fiscal policy
DisadvantagesThey allow
speculation to cause large jumps in exchange rates
They allow government to be flexible in conducting monetary and fiscal policy
Advantages and Disadvantages ofFixed Exchange Rate Systems
Advantages
They provide international monetary stability
They force governments to make adjustments to meet international problems
Disadvantages
If they become unfixed, they create monetary instability
They force governments to make adjustments to meet international problems
Exchange Rates and Domestic Goals
In principle, the government can control the exchange rate with monetary policy
The problem with doing so is that monetary policy also affects the domestic economy
Expansionary monetary policy will push the exchange rate down
Contractionary monetary policy will push the exchange rate up and may decrease domestic income and jobs
Exchange Rates and Domestic Goals
If other countries stop buying U.S. assets that are financing the large trade deficit, the dollar exchange rate will fall
In the short run, the fall in the dollar will increase the prices of imports, creating inflation in the U.S
In the long run, the fall in the exchange rate will improve the competitiveness of the U.S. and increase exports (prices of goods produced domestically would have to decrease to remain competitive with foreign goods)

Chapter Summary
• The balance of payments is made up of the current account and the financial (capital) account
• Exchange rates in perfectly flexible systems are determined by the supply of and demand for a currency
• The following increase demand for foreign currencies and depreciate domestic currencies:
• An increase in domestic income• An increase in domestic prices• A decrease in domestic interest rates• A reduction in trade restrictions on imports
Chapter Summary
• To raise the value of its domestic currency a country can either increase private demand or decrease private supply through contractionary monetary policy
• Expansionary monetary policy, through its effect on interest rates, income, and price level, tends to lower a country’s exchange rate
• Fiscal policy has an ambiguous effect on a country’s exchange rate
Chapter Summary
• A country can stabilize or fix its exchange rate directly by buying and selling its own currency or indirectly by adjusting its monetary and fiscal policy to achieve its exchange rate goal
• It is easier technically for a country to bring the value of its currency down than it is to support its currency
• The purchasing power parity approach can be used to estimate the long-run equilibrium exchange rate
Chapter Summary
• Fixed exchange rates provide international monetary stability but can create enormous monetary instability if they become unfixed
• Fixed exchange rates force governments to make adjustments to meet their international problems
• Flexible exchange rates allow exchange rates to make incremental changes, but are also subject to large jumps in value as a result of speculation
• Flexible exchange rates give governments flexibility in conducting domestic monetary and fiscal policy
Chapter Summary
• A real exchange rate is an exchange rate adjusted for differences in inflation
• A common currency creates strong political ties, reduces the cost of trade, facilitates price comparisons, and creates a larger single market
• A common currency also makes it impossible to have an independent monetary policy
