In the open-economy macroeconomic model, a higher U.S. real exchange rate makes
U.S. goods more expensive relative to foreign goods and reduces the quantity of dollars demanded.
In the open-economy macroeconomic model, equilibrium in the market for foreign-currency exchange is determined by the equality between the supply of dollars which comes from
U.S. net capital outflow and the demand for dollars for U.S. net exports.
If a country has saving of $2 trillion and investment of $1.5 trillion, then it has
a trade surplus and its net capital outflow = $.5 trillion.
The classical dichotomy and monetary neutrality are represented graphically by

crowding-out effect.
A government budget deficit
decreases both net capital outflow and net exports.
During recessions, banks typically choose to hold more excess reserves relative to their deposits. This action
decreases the money multiplier and decreases the money supply.
Other things the same if reserve requirements are decreased, the reserve ratio
decreases, the money multiplier increases, and the money supply increases.

deposits of its customers but not loans to its customers
If P = domestic prices, P* = foreign prices, and e is the nominal exchange rate, which of the following is implied by purchasing-power parity?
e = P*/P
If the nominal exchange rate e is foreign currency per dollar, the domestic price is P, and the foreign price is P*, then the real exchange rate is defined as
e(P/P*),
When the dollar appreciates, U.S.
exports decrease, while imports increase.
Other things the same, as the price level rises, the real value of money
falls and the exchange rate rises.
If there is a surplus in the market for loanable funds, then the interest rate
falls, so national saving falls.
If the Fed increases the money supply, then 1/P
falls, so the value of money falls.
In recent years, the Federal Reserve has conducted policy by setting a target for the

for savers in high income tax brackets than for savers in low income tax brackets.
Net capital outflow is defined as the purchase of
foreign assets by domestic residents minus the purchase of domestic assets by foreign residents.
If Spain has a trade deficit, then
foreign countries purchase more Spanish assets than Spain purchases from them. This makes Spanish saving smaller then Spanish domestic investment.

increased.
When the money market is drawn with the value of money on the vertical axis, an increase in the money supply
increases the price level and decreases the value of money.
If the minimum wage is currently above the equilibrium wage, then a decrease in the minimum wage
increases the quantity of labor demanded but decreases the quantity of labor supplied.
The most important reason for the slope of the aggregate-demand curve is that as the price level
increases, interest rates increase, and investment decreases.
When the interest rate increases, the opportunity cost of holding money
increases, so the quantity of money demanded decreases.
If businesses and consumers become pessimistic, the Federal Reserve can attempt to reduce the impact on the price level and real GDP by
increasing the money supply, which lowers interest rates.
According to monetary neutrality and the Fisher effect, an increase in the money supply growth rate eventually increases
inflation and nominal interest rates, but does not change real interest rates.
If the supply of loanable funds shifts right, then the equilibrium
interest rate falls, so domestic residents will want to purchase more foreign assets.
In an open economy, the source for the demand for loanable funds is
investment + net capital outflow
The concept of present value helps explain why
investment decreases when the interest rate increases, and it also helps explain why the quantity of loanable funds demanded decreases when the interest rate increases.
Refer to Table 29-5. If the bank faces a reserve requirement of 6 percent, then the bank
is in a position to make a new loan of $18,000.

it is a medium of exchange.
A reduction in U.S net exports would shift U.S. aggregate demand
leftward. In an attempt to stabilize the economy, the government could increase expenditures.
When inflation rises, people will desire to hold
less money and will go to the bank more frequently.
When the price level rises more than expected, a firm with a sticky price will sell its output at a price that is
less than it desires and increase its production.
Suppose that Thom experiences a greater loss in utility if he loses $50 than he would gain in utility if he wins $50. This implies that Thom's
marginal utility diminishes as wealth rises, so he must be risk averse.

monthly survey of about 60,000 households.
Other things the same, if the real interest rate in a country falls, domestic residents will desire to purchase
more capital goods and more foreign bonds.
When the real exchange rate for the dollar appreciates, U.S. goods become
more expensive relative to foreign goods, which makes exports fall and imports rise.
Higher inflation makes relative prices
more variable, making it less likely that resources will be allocated to their best use.
Real GDP
moves in the opposite direction as unemployment.
Anna recently graduated from college with a degree in electrical engineering, but she has not yet started working. To be counted as "unemployed" she
must have looked for work no more than four weeks ago.
The value of net exports equals the value of
national saving - domestic investment.
When a government raises its budget deficit, then that country's
national saving falls, so its supply of loanable funds shifts left.
After 1980 in the United States,
national saving fell below investment and net capital outflow was a large negative number.
A decrease in the expected price level shifts
only the short-run aggregate supply curve right.
According to classical macroeconomic theory,
output is determined by the supplies of capital and labor and the available production technology.

paper bills and coins.
Which of the following concepts is most helpful in explaining why investment increases when the interest rate falls?
present value
If purchasing-power parity holds, when a country's central bank increases the money supply, its
price level rises and its currency depreciates relative to other currencies in the world.
An increase in the money supply might indicate that the Fed had
purchased bonds in an attempt to reduce the federal funds rate.
If the real exchange rate between the U.S. and Argentina is 1, then
purchasing-power parity holds, and the amount of dollars needed to buy goods in the U.S. is the same as the amount needed to buy enough Argentinean bolivars to buy the same goods in Argentina.
The aggregate-demand curve shows the
quantity of domestically produced goods and services that households, firms, the government, and customers abroad want to buy at each price level.
Other things the same, a fall in an economy's overall level of prices tends to
raise the quantity demanded of goods and services, but lower the quantity supplied.
Diversification
reduces the likely fluctuation in a portfolio's return and reduces firm-specific risk.
On a bank's T-account, which are part of the bank's assets?
reserves but not deposits made by its customers

rises because the demand for dollars in the market for foreign-currency exchange rises.
If the Mexican nominal exchange rate does not change, but prices rise faster in Mexico than in all other countries, then the Mexican real exchange rate
rises.
The Fed decreases reserves if it conducts open market
sales but not if it auctions term credit
If, at some interest rate, the quantity of money supplied is less than the quantity of money demanded, people will desire to
sell interest-bearing assets, causing the interest rate to increase.
The money supply decreases if the Fed
sells Treasury bonds. The smaller the reserve requirement, the larger the decrease will be.
Changes in the interest rate
shift aggregate demand if they are caused by fiscal or monetary policy, but not if they are caused by changes in the price level.
Financial Crisis: Suppose that banks are less able to raise funds and so lend less. Consequently, because people and households are less able to borrow, they spend less at any given price level than they would otherwise. The crisis is persistent so lending should remain depressed for some time. Refer to Financial Crisis. In the long run, if the Fed does not respond, the change in price expectations created by the crisis shifts
short-run aggregate supply right.
Refer to Figure 32-1. If the real interest rate is 2 percent, there will be a
shortage of $40 billion.
If France had positive net exports last year, then it
sold more abroad than it purchased abroad and had a trade surplus.
The efficient markets hypothesis says that
stock prices follow a random walk.
Efficiency wages contribute to
structural unemployment and the natural rate of unemployment.
If there were no factors keeping wages from reaching equilibrium then there would be no
structural unemployment.
In order to understand how the economy works in the short run, we need to
study a model in which real and nominal variables interact.
Refer to Figure 32-3. National saving is represented by the
supply curve in panel a.
Other things the same, an increase in the U.S. interest rate causes
supply in the market for foreign-currency exchange to increase so the exchange rate decreases. (wrong)
Refer to Figure 30-1. If the money supply is MS2 and the value of money is 2, then there is an excess
supply of money that is represented by the distance between points A and B.

the price level and nominal GDP
According to the classical dichotomy, when the money supply doubles, which of the following also doubles?
the price level and nominal wages
