CHAPTER 01: THE SCIENCE OF MACROECOMICS
MULTIPLE CHOICES
1. A macroeconomist builds a simplified representation of how changes in interest rates affect investment spending.
This representation is called a(n):
A) hypothesis
B) economic model
C) controlled experiment
D) data set
Answer: B
An economic model abstracts from real-world complexity to focus on key relationships and test theories.
2. Which of the following variables is typically treated as exogenous in a macroeconomic model of the circular
flow?
A) Consumption spending
B) Government tax rates
C) Output produced by firms
D) Investment decisions
Answer: B
Exogenous variables are determined outside the model; tax rates are often set by policy and taken as given.

,3. A researcher observes that when unemployment rises, inflation tends to fall. This is an example of:
A) a positive correlation
B) a controlled experiment
C) a normative statement
D) an exogenous shock
Answer: A
Positive correlation means two variables move together in a predictable way, but does not imply causation.
4. If a macroeconomist says, "The government should lower taxes to reduce unemployment," this is a:
A) positive statement
B) normative statement
C) empirical fact
D) model assumption
Answer: B
Normative statements involve value judgments about what should be done, not purely factual claims.
5. Which of the following is a stock variable?
A) Gross Domestic Product (annual)
B) Investment spending per year
C) The national debt as of December 31
D) Government purchases in 2025
Answer: C
A stock variable is measured at a point in time; the national debt is a stock, while flows are per time period.
6. In the circular flow model, households provide factors of production to firms and receive:
A) goods and services
2|Page SUCCESS!!!
,B) wages, rent, and profit
C) taxes and transfers
D) intermediate goods
Answer: B
Households supply labor, capital, and land; firms pay factor incomes (wages, rent, interest, profit).
7. The endogenous variables in a model are:
A) determined outside the model
B) explained within the model
C) policy instruments only
D) never measured
Answer: B
Endogenous variables are the outcomes the model seeks to explain; exogenous variables are inputs.
8. A macroeconomist wants to test whether higher minimum wages cause higher unemployment. The ideal method
would be:
A) a randomized controlled experiment
B) running a regression with historical data
C) asking a panel of experts
D) assuming the relationship is zero
Answer: A
Randomized experiments are the gold standard for causality, but they are rare in macroeconomics.
9. Which of the following is a flow variable?
A) The number of people unemployed in January
B) The capital stock on December 31

, C) Consumer spending during 2024
D) The money supply on June 30
Answer: C
Flow variables are measured over an interval of time; consumer spending occurs continuously over a period.
10. A model that assumes prices are flexible in the long run but sticky in the short run is an example of:
A) a microeconomic model
B) a simplifying assumption to capture reality
C) an untestable hypothesis
D) a normative framework
Answer: B
Economists use realistic assumptions about price behavior to match observed short-run and long-run outcomes.
11. The fact that macroeconomics must often rely on observational data rather than controlled experiments means
that:
A) causation is easy to prove
B) correlation often implies causation
C) economists must use statistical techniques to isolate causal effects
D) models are useless
Answer: C
With observational data, econometric methods like instrumental variables help address confounding factors.
12. The production function Y = F(K, L) is an example of a model that:
A) determines prices endogenously
B) shows how inputs (capital, labor) produce output
C) explains inflation
