, Question 1: Analyzing Aggregate Demand Shocks
Scenario: In a large economy, a sudden decline in consumer confidence
causes households to reduce spending. As a result, aggregate demand
falls sharply. Which macroeconomic model best explains the short‑run
decrease in output and potential deflationary pressures?
- A. IS‑LM model
- B. AD‑AS (Aggregate Demand‑Aggregate Supply) model
- C. Quantity Theory of Money
- D. Real Business Cycle Theory
ANS: B
Rationale: The AD‑AS model illustrates how a negative demand shock
(a fall in aggregate demand) can result in lower output and downward
pressure on prices in the short run.
---
Question 2: Monetary Policy Transmission Mechanism
Scenario: To combat a recession, a central bank decides to reduce the
policy interest rate. Which channel is most directly responsible for
boosting investment spending as a result?
- A. Interest rate channel
- B. Exchange rate channel
- C. Expectations channel
- D. Balance sheet channel
ANS: A
Rationale: The interest rate channel explains how lower policy rates
reduce borrowing costs, which in turn stimulates investment and
consumption spending, thereby raising aggregate demand.
---
Question 3: Fiscal Multipliers and Economic Stimulus

, Scenario: The government increases public infrastructure spending by
$100 million. Which concept best describes the total rise in national
income that may result from this spending?
- A. Crowding‑out effect
- B. Fiscal multiplier
- C. Ricardian equivalence
- D. Laffer Curve
ANS: B
Rationale: The fiscal multiplier measures how much additional income
is generated for each dollar of government spending. A positive
multiplier means that the total rise in income exceeds the initial
spending.
---
Question 4: Phillips Curve Dynamics
Scenario: A country experiences a period in which unemployment falls
below its natural rate, and inflation begins rising accompanied by higher
inflation expectations. Which curve best captures the short‑run trade‑off
between inflation and unemployment?
- A. Laffer Curve
- B. Phillips Curve
- C. Kuznets Curve
- D. Laffer Ratio
ANS: B
Rationale: The Phillips Curve depicts the short‑run inverse relationship
between inflation and unemployment; when unemployment falls below
its natural rate, inflation may accelerate.
---
Question 5: Wage-Price Spiral Analysis
Scenario: In an economy, rising inflation expectations cause workers to
©2025
, demand higher wages, which then increase production costs and further
fuel inflation. What is this phenomenon known as?
- A. Cost‑push inflation
- B. Demand‑pull inflation
- C. Wage‑price spiral
- D. Hyperinflation cycle
ANS: C
Rationale: The wage‑price spiral refers to the iterative process in
which rising wages lead to higher production costs, increasing prices
further and prompting more wage demands.
---
Question 6: Long‑Run Growth Theory – Factor Accumulation
Scenario: Two countries are compared: Country A and Country B.
Country A invests more heavily in physical capital and displays higher
rates of capital accumulation, which contributes to a higher level of GDP
per capita in the long run. Which model best explains these differences?
- A. Endogenous Growth Theory
- B. Real Business Cycle Theory
- C. Solow Growth Model
- D. Malthusian Theory
ANS: C
Rationale: The Solow Growth Model explains long‑run economic
growth through capital accumulation, labor growth, and exogenous
technological progress, with differences in capital accumulation
contributing to variations in GDP per capita.

Question 7: Endogenous Growth and Innovation
Scenario: A government launches a program that supports research and
development and improves higher‑education systems with the intent of
