Question 1: According to the classical dichotomy, which of the following is a real variable?
A. The nominal interest rate
B. The price of a good measured in dollars
C. The wage of a worker measured in current dollars
D. The quantity of output produced in the economy
CORRECT ANSWER: D. The quantity of output produced in the economy
Rationale: The classical dichotomy is the theoretical separation of real and nominal variables.
Real variables are measured in physical units, such as the quantity of goods and services
produced (real GDP) or the real wage, while nominal variables are measured in monetary units,
such as the price level or nominal wage . Therefore, the quantity of output is a real variable.
Question 2: The property that changes in the money supply affect only nominal variables, not
real variables, in the long run is known as:
A. The classical dichotomy
B. Monetary neutrality
C. The Fisher effect
D. The interest rate effect
CORRECT ANSWER: B. Monetary neutrality
Rationale: Monetary neutrality is the property that a change in the money supply does not
affect real variables like output or employment in the long run. Instead, it only changes nominal
variables like the price level and wages . The classical dichotomy is the theoretical separation of
these variables .
Question 3: If the money supply doubles in the long run, which of the following outcomes is
most consistent with monetary neutrality?
,A. Real output doubles
B. The price level doubles
C. The unemployment rate falls
D. Real wages increase significantly
CORRECT ANSWER: B. The price level doubles
Rationale: Under monetary neutrality, a doubling of the money supply leads to a proportional
doubling of all nominal variables, such as the price level, wages, and all dollar values. Real
variables, such as real output, employment, and real wages, remain unchanged .
Question 4: Which of the following correctly defines nominal variables?
A. Variables measured in physical units
B. Variables that are unaffected by changes in the money supply
C. Variables measured in monetary units and affected by changes in the money supply
D. Variables that determine the long-run growth of the economy
CORRECT ANSWER: C. Variables measured in monetary units and affected by changes in the
money supply
Rationale: Nominal variables are economic variables expressed in monetary units, such as the
dollar price of a good, nominal GDP, or the nominal wage. They are directly affected by changes
in the overall money supply .
Question 5: In the long-run, the economy is best described by which of the following
statements?
A. Nominal and real variables are independent of each other.
B. Changes in the money supply have a significant impact on real output.
C. Monetary policy is an effective tool to manage unemployment.
D. Prices and wages are "sticky" and do not adjust quickly.
CORRECT ANSWER: A. Nominal and real variables are independent of each other.
Rationale: In the long run, the principles of the classical dichotomy and monetary neutrality
apply, meaning that nominal variables do not affect real variables. The economy operates at its
natural level of output, which is determined by real factors like labor, capital, and technology .
Question 6: The model of aggregate demand and aggregate supply is primarily used to
explain:
A. Long-run economic growth
B. Short-run economic fluctuations
C. The natural rate of unemployment
D. The distribution of income
,CORRECT ANSWER: B. Short-run economic fluctuations
Rationale: The AD-AS model is the primary tool used by economists to analyze short-run
fluctuations in the economy, such as recessions and booms. It shows how the price level and
real GDP interact to move the economy away from its long-run trend .
Question 7: In the model of aggregate demand and aggregate supply, the vertical axis
measures the:
A. Real interest rate
B. Quantity of output (real GDP)
C. Price level
D. Money supply
CORRECT ANSWER: C. Price level
Rationale: In the standard AD-AS model, the price level is measured on the vertical axis, often
using the GDP deflator or the Consumer Price Index (CPI) . Real GDP is measured on the
horizontal axis.
Question 8: Which of the following is a reason why the aggregate-demand curve slopes
downward?
A. The wealth effect
B. The Fisher effect
C. The classical dichotomy
D. The production function
CORRECT ANSWER: A. The wealth effect
Rationale: The aggregate-demand curve slopes downward for three main reasons: the wealth
effect, the interest-rate effect, and the exchange-rate effect . The wealth effect (or real-
balances effect) posits that a lower price level increases the real value of money, making
consumers wealthier and leading to more spending on consumption .
Question 9: The interest-rate effect explains that a lower price level leads to:
A. Higher interest rates, which reduces investment spending
B. Higher interest rates, which increases investment spending
C. Lower interest rates, which increases investment spending
D. No change in interest rates, but an increase in consumption
CORRECT ANSWER: C. Lower interest rates, which increases investment spending
Rationale: When the price level falls, households need to hold less money to buy goods and
services. They lend out this excess money (e.g., by buying bonds), which drives down interest
, rates. Lower interest rates then stimulate investment spending, thus increasing the quantity of
goods and services demanded .
Question 10: How does the exchange-rate effect influence aggregate demand?
A. Higher prices lead to lower interest rates, a depreciation of the dollar, and a rise in exports.
B. Lower prices lead to lower interest rates, a depreciation of the dollar, and a rise in net
exports.
C. Lower prices lead to higher interest rates, an appreciation of the dollar, and a rise in imports.
D. Exchange rates have no effect on aggregate demand in a closed economy.
CORRECT ANSWER: B. Lower prices lead to lower interest rates, a depreciation of the dollar,
and a rise in net exports.
Rationale: A lower domestic price level leads to lower interest rates. This makes domestic
assets less attractive to foreign investors, causing the real exchange rate to depreciate. A
weaker dollar makes domestic goods cheaper relative to foreign goods, boosting exports and
reducing imports, which increases net exports and aggregate demand .
Question 11: A significant decline in stock market values that makes households feel less
wealthy would cause:
A. Movement down along the aggregate-demand curve
B. A rightward shift of the aggregate-demand curve
C. Movement up along the aggregate-demand curve
D. A leftward shift of the aggregate-demand curve
CORRECT ANSWER: D. A leftward shift of the aggregate-demand curve
Rationale: A decrease in household wealth leads to lower consumption spending at any given
price level. This change in "consumption" is a non-price determinant of aggregate demand,
which causes the entire aggregate-demand curve to shift to the left .
Question 12: A firm's optimism about the future economy leading to an increase in purchases
of new equipment would cause:
A. A leftward shift of the aggregate-demand curve
B. A rightward shift of the aggregate-demand curve
C. A leftward shift of the short-run aggregate-supply curve
D. No shift; it is a movement along the aggregate-demand curve
CORRECT ANSWER: B. A rightward shift of the aggregate-demand curve
Rationale: An increase in business optimism leads to higher investment spending. This is a
change in one of the components of aggregate demand (Investment), shifting the aggregate-
demand curve to the right at every price level .
