Macroeconomics final exam
Supply-side economists believe that changes in government purchases affect
both aggregate demand and aggregate supply.
If Congress cuts spending to balance the federal budget, the Fed can act to prevent unemployment and recession by
buying bonds to increase the money supply
When the Fed decreases the money supply, we expect
interest rates to rise and stock prices to fall.
If the Fed conducts open-market purchases, then which of the following quantities increase(s)?
interest rates, but not prices or investment spending
Recession come at
irregular intervals. During recessions investment spending falls relatively more than consumption spending.
A country has $60 million of saving and domestic investment of $40 million. Net exports are
$20 million.

$20.
What are Argentina's exports?
$35 billion
Oceania buys $40 of wine from Escudia and Escudia buys $100 of wool from Oceania. Supposing this is the only trade that these countries do. What are the net exports of Oceania and Escudia in that order?
$60 and -$60
What are Argentina's imports?
$60 billion
In an open economy, gross domestic product equals $2,450 billion, consumption expenditure equals $1,390 billion, government expenditure equals $325 billion, investment equals $510 and net capital outflow equals $225 billion. What is national saving?

-$25 billion
In the United States, a three-pound can of coffee costs about $5. If the exchange rate is about 0.6 euros per dollar and a three-pound can of coffee in Belgium costs about 4 euros. What is the real exchange rate?
3/4 cans of Belgian coffee per can of U.S. coffee
The aggregate demand and aggregate supply graph has
quantity of output on the horizontal axis. Output can be measured by the GDP deflator.
Other things the same, if the exchange rate changes from 125 yen per dollar to 115 yen per dollar, the dollar has
depreciated and so buys fewer Japanese goods.
The exchange rate is 1.5 Bosnian markas per U.S. dollar. The price of a refrigerator in Bosnia is 1,200 markas while in the U.S. it is $1,000. The real exchange rate is
5/4
If the exchange rate is 5 units of Peruvian currency per dollar and a hotel room in Lima costs 300 units of Peruvian currency, then how many dollars do you need to get a room?
60 and your purchase will increase Peru's net exports.
In the short run, a favorable shift in aggregate supply would move the economy from
A to B.
An increase in the money supply would move the economy from C to
B in the short run and A in the long run.
If the economy is in long-run equilibrium, then an adverse shift in aggregate supply would move the economy from
C to D.
The economy would be moving to long-run equilibrium if it started at
D and moved to C.
Suppose a Starbucks tall-latte cost $4.00 in the United States and 3.20 euros in the Euro area. Also, suppose a McDonald's Big Mac costs $3.50 in the United States and 2.45 euros in Euro area. If the nominal exchange rate is .80 euros per dollar, which goods have prices that are consistent with purchasing power parity?
Neither the tall-latte nor the Big Mac.
Which of the sentences concerning the aggregate demand and aggregate supply model is correct?
The price level and quantity of output adjust to bring aggregate demand and supply into balance
U.S. based John Deere sells machinery to residents of South Africa who pay with South African currency (the rand)
This increases U.S. net capital outflow because the U.S. acquires foreign assets.
When Claudia, a U.S. citizen, purchases a handbag made in France, the purchase is
a U.S. import and a French export.
Which of the following shifts aggregate demand to the left?
a decrease in the money supply
If the stock market crashes, then
aggregate demand increases, which the Fed could offset by increasing the money supply.
The multiplier effect is exemplified by the multiplied impact on
aggregate demand of a given increase in government purchases.
Policymakers who control monetary and fiscal policy and want to offset the effects on output of an economic contraction caused by a shift in aggregate supply could use policy to shift
aggregate demanded to the right
The long-run aggregate supply curve shifts right if
all of the above
Bob, a Greek citizen, opens a restaurant in Chicago. His expenditures
decrease U.S. net capital outflow, but increase Greek net capital outflow.
Suppose a fall in stock prices makes people feel poorer. The decrease in wealth would induce people to desire
decreased consumption, shifting the aggregate-demand curve to the left.
When taxes increase, consumption
decreases, so aggregate supply shifts left.
Other things the same, during recessions taxes tend to
fall. The fall in taxes stimulates aggregate demand.
During recessions investment
falls by about the same percentage as GDP
A U.S. firm buys bonds issued by a technology center in India. This purchase is an example of U.S
foreign portfolio investment. By itself it is an increase in U.S. holdings of foreign bonds and increases U.S. net capital outflow.
Other things the same, if the price level rises by 2% and people were expecting it to rise by 5%, then some firms have
higher than desired prices which depresses their sales.
Fiscal policy affects the economy
in both the short and long run.
If the Fed conducts open-market purchases, the money supply
increases and aggregate demand shifts right.
A depreciation of the U.S. real exchange rate induces U.S. consumers to buy
more domestic goods and fewer foreign goods
If the economy starts at A and moves to D in the short run, the economy
moves to C in the long run.
If the economy is at A and there is a fall in aggregate demand, in the short run the economy
moves to D
Other things the same, if a country saves less, then
net capital outflow falls, so net exports fall.
Which type(s) of economies interact with other economies?
only open economies
A decrease in the expected price level shifts
only the short-run aggregate supply curve right.
Most economists believe that fiscal policy
primarily affects aggregate demand
Which of the following is not included in aggregate demand?
purchases of stock and bonds
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 nominal exchange rate is the
rate at which a person can trade the currency of one country for another.
The model of short-run economic fluctuations focuses on the price level and
real GDP.
The aggregate quantity of goods and services demanded changes as the price level rises because
real wealth falls, interest rates rise, and the dollar depreciates.
Stagflation exists when prices
rise and output falls
Other things the same, if the price level rises, then domestic interest rates
rise, so domestic residents will want to hold fewer foreign bonds.
Other things the same, when the price level rises, interest rates
rise, so firms decrease investment.
If there is a trade deficit, then
saving is less than domestic investment and Y < C + I + G
In the long run, fiscal policy primarily affects
saving, investment, and growth. In the short run, it affects primarily aggregate demand
Suppose there were a large increase in net exports. If the Fed wanted to stabilize output, it could
sell bonds to decrease the money supply
.Suppose that the Federal reserve is concerned about the effects of rising stock prices on the economy. What could it do?
sell bonds to raise the interest rate
Which of the following would cause prices to fall and output to rise in the short run?
short-run aggregate supply shifts right
. You are planning a graduation trip to Nepal. Other things the same, if the dollar appreciates relative to the Nepalese rupee, then
the dollar buys more rupees. Your purchases in Nepal will require fewer dollars
As the price level falls,
the exchange rate rises, so net exports fall.
The discovery of a large amount of previously-undiscovered oil in the U.S. would shift
the long-run aggregate-supply curve to the right
Suppose the economy is in long-run equilibrium. In a short span of time, there is a decline in the money supply, a tax increase, a pessimistic revision of expectations about future business conditions, and a rise in the value of the dollar. In the short run, we would expect
the price level and real GDP both to fall.
The sticky-wage theory of the short-run aggregate supply curve says that the quantity of output firms supply will increase if
the price level is higher than expected making production more profitable.
Suppose the economy is in long-run equilibrium. Senator A succeeds in getting taxes raised. At the same time, Senator B succeeds in getting major new restrictions on logging enacted. In the short run
the price level will fall, and real GDP might rise, fall, or stay the same.
Aggregate demand includes
the quantity of goods and services households, firms, the government, and customer abroad want to buy.
The term crowding-out effect refers to
the reduction in aggregate demand that results when a fiscal expansion causes the interest rate to increase.
Real and nominal variables are highly intertwined, and changes in the money supply change real GDP. Most economists would agree that this statement accurately describes
the short run, but not the long run.
When production costs rise,
the short-run aggregate supply curve shifts to the left.
The primary argument against active monetary and fiscal policy is that
these policies affect the economy with a long lag
If the economy starts at A and there is a fall in aggregate demand, the economy moves
to C in the long run.
During periods of expansion, automatic stabilizers cause government expenditures
to fall and taxes to rise
Which of the following will both make people spend more?
