Net exports equation
(value of country's exports) - (value of country's imports)
Balanced trade
a situation in which exports equal imports
Exports
domestically produced goods and services that are sold abroad
If the United States saves $1,000 billion and U.S. net capital outflow is -$200 billion, U.S. domestic investment is
$1,200 billion.
How trade surplus and deficits effect the economy as a whole:
- When a nation is running a trade surplus (NX > 0), it sells more goods and services to foreigners than it buys from them. The nation must use this foreign currency to buy foreign assets. Capital is flowing out of the country. - When a nation is running a trade deficit (NX < 0), it is buying more goods and services from foreigners than it is selling to them. The nation must sell assets abroad in order to finance the net purchase of these goods and services in the world market. Capital is flowing into the country (NCO < 0)
Which of the following statements is true about a country with a trade deficit a. Net exports are negative. b. Net capital outflow must be positive. c.Exports exceed imports. d. Net exports are positive. e. none of these answers

Suppose a U.S. resident buys a Jaguar automobile from Great Britain and the British exporter uses the receipts to buy stock in General Electric. Which of the following statements is true from the perspective of the United States?
Net exports rise, and net capital outflow rises.
Real exchange rate equation
Real exchange rate = (nominal exchange rate x domestic price) / (foreign price)
National savings is income of the nation that is left after paying current consumption and government purchases: S = Y - C - G. if we rearrange the equation to reflect this fact, we obtain:
S = I + NCO (Saving) = (Domestic Investment) + (Net Capital Outflow)
The economy's GDP (Y) is divided among four components: consumption ©, investment (I), government purchases (G), and net exports (NX). We write this as:
Y = C + I + G + NX (economy's GDP) = (consumption) + (investment) + (government purchases) + (net exports)
Purchasing-power parity
a theory of exchange rats whereby a unit of any given currency should be able to buy the same quantity of goods in all countries.
Net exports
any country are is the difference between the value of its exports and the value of its imports

Purchasing power equation
e / P*
nominal exchange rate equation
e = P*/P
Which of the following products would likely be the least accurate if used to calculate purchasing-power parity? a. Diamonds b. Gold c. Cars d. Wheat e. Dental services
e. Dental services
Imports
foreign-produced goods and services that are sold domestically
Suppose the money supply in Mexico grows more quickly than the money supply in the United States. We would expect that
the Mexican peso should depreciate relative to the US dollar.
If the exchange rate changes from 3 Brazilian reals per dollar to 4 reals per dollar,
the euro has appreciated.

Over this period, a. the value of the dollar should have fallen compared to the value of the pound and the yen. b. none of these answers c. the yen should have fallen in value compared to the pound and risen compared to the dollar. d. the value of the pound should have risen compared to the value of the yen and the dollar. e. the yen should have risen in value compared to the pound and fallen compared to the dollar.
the yen should have risen in value compared to the pound and fallen compared to the dollar.
Depreciation
a decrease in the value of a currency as measured by the amount of foreign currency it can buy
An economy that interacts with other economies is known as
an open economy.
When people take advantage of differences in prices for the same good by buying it where it is cheap and selling it where it is expensive, it is known as
arbitrage.
Trade surplus
occurs when a country has an excess of exports over imports
Net capital outflow
the purchase of foreign assets by domestic residents minus the purchase of domestic assets by foreigners
Real exchange rate
the rate at which a person can trade the goods and services of one country for the goods and services of another
Net capital outflow equation
(Net capital outflow) = (purchase of foreign assets by domestic residents) - (Purchase of domestic assets by foreigners)
Real exchange rate equation:
(real exchange rate) = (e x P) / (P*) P = price index for a basket P* = price index for a foreign basket e = Nominal exchange rate between the currencies
Trade Deficit characteristics
- Exports < Imports - Net Exports < 0 - Y < C + I + G - Saving < Investment - Net capital outflow < 0
Balanced Trade characteristics
- Exports = Imports - Net Exports = 0 - Y = C + I + G - Saving = Investment - Net capital outflow = 0
Trade Surplus characteristics
- Exports > Imports - Net exports > 0 - Y > C + I + G - Saving > Investment - Net capital outflow > 0
Some important variables that influence net capital outflow:
- Real interest rates paid on foreign assets - Real interest rates paid on domestic assets - The perceived economic and political risk of holding assets abroad - The government policies that affect foreign ownership of domestic assets
Trade deficit
an excess of imports over exports
The most accurate measure of the international value of the dollar is
an exchange rate index that accounts for many exchange rates.
Appreciation
an increase in the value of a currency as measured by the amount of foreign currency it can buy
In a closed economy
net capital outflow is zero (NCO = 0), so saving equals investment (S = I).
For an economy as a whole, net capital outflow (NCO) must always equal
net exports (NX)
Nominal exchange rate
the rate at which a person can trade the currency of one country for the currency of another
Trade balance
the value of a nation's exports minus the value of its imports; also called net exports
