INTRODUCTION
This examination is designed to assess a comprehensive understanding of microeconomic theory and its
practical application in professional and regulatory environments. It evaluates skills in analyzing market
dynamics, optimizing firm decisions, interpreting economic data, and applying ethical standards. The
exam features multiple-choice and scenario-based questions that require critical thinking, problem-
solving, and professional judgment. The focus is on real-world application, ensuring candidates can make
sound economic decisions within legal and ethical frameworks. This assessment serves as a final review
for mastery of microeconomic principles essential for advanced study and professional practice.
SECTION ONE – QUESTIONS 1–100
Question 1
The fundamental economic problem of scarcity arises because:
A. Human wants are unlimited, but resources are limited.
B. Governments do not allocate resources efficiently.
C. Technological progress is always slow.
D. Consumers do not know what they want.
🟢 A. Human wants are unlimited, but resources are limited.
🔴 Explanation: Scarcity is the core economic problem defined by unlimited wants and limited
resources, forcing choices.
Question 2
In a perfectly competitive market, a single firm faces a demand curve that is:
A. Downward sloping.
B. Perfectly inelastic.
,C. Perfectly elastic.
D. Upward sloping.
🟢 C. Perfectly elastic.
🔴 Explanation: In perfect competition, firms are price takers; they can sell all output at the market
price, so demand is perfectly elastic (horizontal).
Question 3
A legal maximum price set below the equilibrium price is called a:
A. Price floor.
B. Price ceiling.
C. Subsidy.
D. Tariff.
🟢 B. Price ceiling.
🔴 Explanation: A price ceiling is a maximum legal price. If set below equilibrium, it causes a shortage.
Question 4
Which of the following best describes the law of demand?
A. As price rises, quantity demanded rises.
B. As price rises, quantity demanded falls.
C. As income rises, demand falls.
D. As supply rises, demand rises.
🟢 B. As price rises, quantity demanded falls.
🔴 Explanation: The law of demand states there is an inverse relationship between price and quantity
demanded, all else equal.
Question 5
The price elasticity of demand measures:
A. The slope of the demand curve.
B. The responsiveness of quantity demanded to a change in price.
C. The responsiveness of supply to a change in price.
D. The change in demand due to income.
🟢 B. The responsiveness of quantity demanded to a change in price.
🔴 Explanation: Price elasticity of demand quantifies how much quantity demanded changes in
response to a price change.
Question 6
If a 10% increase in price leads to a 20% decrease in quantity demanded, demand is:
A. Inelastic.
B. Unit elastic.
C. Elastic.
D. Perfectly inelastic.
🟢 C. Elastic.
🔴 Explanation: Elasticity = % change in quantity / % change in price = 20/10 = 2. Since >1, demand is
,elastic.
Question 7
A firm's total revenue is maximized when:
A. Marginal revenue is zero.
B. Marginal cost is zero.
C. Price is highest.
D. Demand is inelastic.
🟢 A. Marginal revenue is zero.
🔴 Explanation: Total revenue is maximized where marginal revenue equals zero, before it becomes
negative.
Question 8
Which of the following is a fixed cost for a manufacturing firm?
A. Raw materials.
B. Hourly wages.
C. Factory rent.
D. Electricity for production.
🟢 C. Factory rent.
🔴 Explanation: Fixed costs do not vary with output. Factory rent is paid regardless of production level.
Question 9
The marginal cost curve intersects the average total cost curve at:
A. The minimum of average total cost.
B. The maximum of average total cost.
C. The minimum of marginal cost.
D. The maximum of marginal cost.
🟢 A. The minimum of average total cost.
🔴 Explanation: When marginal cost is below average total cost, ATC falls; when above, ATC rises. The
intersection is the minimum of ATC.
Question 10
In the short run, a perfectly competitive firm should shut down if:
A. Price is less than average total cost.
B. Price is less than average variable cost.
C. Price is less than marginal cost.
D. It is making zero economic profit.
🟢 B. Price is less than average variable cost.
🔴 Explanation: If price cannot cover average variable cost, the firm minimizes losses by shutting
down.
Question 11
A monopoly's marginal revenue is:
A. Equal to price.
, B. Greater than price.
C. Less than price.
D. Equal to average revenue.
🟢 C. Less than price.
🔴 Explanation: To sell more, a monopolist must lower price on all units, so marginal revenue is less
than price.
Question 12
Which market structure is characterized by a few large firms and significant barriers to entry?
A. Perfect competition.
B. Monopolistic competition.
C. Oligopoly.
D. Monopoly.
🟢 C. Oligopoly.
🔴 Explanation: Oligopoly has few firms, interdependence, and barriers to entry.
Question 13
The demand for labor is derived from:
A. The supply of labor.
B. The demand for the final product.
C. Government regulations.
D. Union contracts.
🟢 B. The demand for the final product.
🔴 Explanation: Labor demand is derived from the demand for the goods and services labor produces.
Question 14
A negative externality occurs when:
A. A firm's production costs are lower than social costs.
B. A firm's production benefits society.
C. Consumers pay too much.
D. Government taxes are too high.
🟢 A. A firm's production costs are lower than social costs.
🔴 Explanation: A negative externality exists when private costs are less than social costs, leading to
overproduction.
Question 15
A public good is characterized by:
A. Rivalry and excludability.
B. Non-rivalry and non-excludability.
C. Rivalry and non-excludability.
D. Non-rivalry and excludability.
🟢 B. Non-rivalry and non-excludability.
🔴 Explanation: Public goods are non-rival (one person's use doesn't reduce availability) and non-
