QUESTIONS (2026 Edition)
1. Which of the following best describes a market economy? A) The government owns all means of
production and distributes goods equally B) Economic decisions are made by individuals and businesses
based on supply and demand C) Traditional customs and beliefs determine production and distribution
methods D) A central planning committee sets all prices and production quotas
ANSWERB
• Rationale for A: Incorrect. This describes a command/communist economy, not a market
economy.
• Rationale for B: Correct. In a market economy, decentralized decisions by households and firms
interacting in markets drive resource allocation through supply and demand mechanisms.
• Rationale for C: Incorrect. This describes a traditional economy, where customs, history, and
time-honored beliefs guide economic behavior.
• Rationale for D: Incorrect. This describes a command economy with central planning, the
opposite of market-based decision making.
2. When the Federal Reserve raises the discount rate, what is the most likely immediate effect on the
economy? A) Increased consumer spending due to higher confidence B) Decreased borrowing by
commercial banks, leading to tighter money supply C) Immediate reduction in unemployment rates D)
Increased exports due to stronger domestic currency
ANSWERB
• Rationale for A: Incorrect. Higher discount rates typically reduce, not increase, consumer
spending by making credit more expensive.
• Rationale for B: Correct. The discount rate is the interest rate the Fed charges banks for short-
term loans; raising it makes borrowing costlier for banks, reducing their reserves and tightening
the money supply.
, • Rationale for C: Incorrect. Tighter monetary policy typically slows economic activity and may
increase, not decrease, unemployment in the short run.
• Rationale for D: Incorrect. While a stronger currency might result eventually, the immediate
effect is on domestic credit conditions; also, a stronger currency typically reduces, not increases,
exports.
3. Which scenario best illustrates the concept of opportunity cost? A) A company spends $1 million on
new equipment B) A student chooses to study economics instead of working a part-time job C) The
government increases taxes to fund infrastructure D) A consumer buys a discounted item during a sale
ANSWERB
• Rationale for A: Incorrect. This describes a capital expenditure but does not explicitly show the
trade-off of the next best alternative forgone.
• Rationale for B: Correct. Opportunity cost is the value of the next best alternative given up;
here, the wages and experience from the part-time job represent the opportunity cost of
studying.
• Rationale for C: Incorrect. This describes fiscal policy and resource allocation but does not
clearly identify the specific trade-off at the individual decision-making level.
• Rationale for D: Incorrect. This describes a purchasing decision based on price incentives, not
the explicit trade-off of alternatives.
4. In which market structure would you expect to find a single seller with significant control over price
and high barriers to entry? A) Perfect competition B) Monopolistic competition C) Oligopoly D)
Monopoly
ANSWERD
• Rationale for A: Incorrect. Perfect competition features many sellers, homogeneous products,
and no single firm can influence price.
• Rationale for B: Incorrect. Monopolistic competition has many sellers with differentiated
products and relatively low barriers to entry.
• Rationale for C: Incorrect. Oligopoly features a few large firms that may have market power, but
not a single seller.
• Rationale for D: Correct. A monopoly is defined by a single seller, unique product with no close
substitutes, significant price control, and high barriers preventing entry.
5. Which of the following is a key component of Gross Domestic Product (GDP) calculated using the
expenditure approach? A) Transfer payments like Social Security B) Intermediate goods used in
production C) Business investment in capital goods D) Sales of used goods
ANSWERC
, • Rationale for A: Incorrect. Transfer payments are excluded from GDP because they do not
represent payment for current production of goods or services.
• Rationale for B: Incorrect. Intermediate goods are excluded to avoid double-counting; only final
goods and services are included in GDP.
• Rationale for C: Correct. Business investment (I) in capital goods like machinery, buildings, and
equipment is one of the four expenditure components: C + I + G + (X-M).
• Rationale for D: Incorrect. Sales of used goods are excluded because they were counted in GDP
when first produced; including them again would double-count production.
6. If the price elasticity of demand for a product is -0.5, how is demand characterized? A) Elastic B)
Inelastic C) Unit elastic D) Perfectly elastic
ANSWERB
• Rationale for A: Incorrect. Elastic demand has an absolute value greater than 1, meaning
quantity demanded changes proportionally more than price.
• Rationale for B: Correct. Inelastic demand has an absolute value less than 1; here, |−0.5| = 0.5 <
1, so quantity demanded changes less than proportionally to price changes.
• Rationale for C: Incorrect. Unit elastic demand has an absolute value exactly equal to 1.
• Rationale for D: Incorrect. Perfectly elastic demand has an elasticity of negative infinity,
represented by a horizontal demand curve.
7. Which policy tool would the Federal Reserve most likely use to combat high inflation? A) Decrease
the reserve requirement B) Purchase government securities in open market operations C) Increase the
federal funds rate target D) Lower the discount rate
ANSWERC
• Rationale for A: Incorrect. Decreasing reserve requirements increases banks' lending capacity,
expanding money supply and potentially worsening inflation.
• Rationale for B: Incorrect. Purchasing securities injects reserves into the banking system,
increasing money supply, which is expansionary and inappropriate for fighting inflation.
• Rationale for C: Correct. Raising the federal funds rate target is a contractionary monetary
policy that increases borrowing costs, reduces spending and investment, and helps cool
inflationary pressures.
• Rationale for D: Incorrect. Lowering the discount rate makes borrowing cheaper for banks,
increasing money supply, which is expansionary and counterproductive against inflation.
8. What is the primary purpose of antitrust laws in the United States? A) To protect domestic
industries from foreign competition B) To ensure businesses pay fair wages to employees C) To promote
competition and prevent monopolistic practices D) To regulate the environmental impact of business
operations
, ANSWERC
• Rationale for A: Incorrect. Trade policies, tariffs, and import quotas address foreign
competition, not antitrust laws.
• Rationale for B: Incorrect. Labor laws and minimum wage statutes address wage issues, not
antitrust legislation.
• Rationale for C: Correct. Antitrust laws like the Sherman Act and Clayton Act aim to prevent
anti-competitive mergers, price-fixing, and monopolization to protect consumer welfare and
market efficiency.
• Rationale for D: Incorrect. Environmental regulations like the Clean Air Act address ecological
concerns, separate from competition policy.
9. Which of the following best describes comparative advantage? A) A country can produce more of a
good with the same resources than another country B) A country can produce a good at a lower
opportunity cost than another country C) A country has absolute control over the production of a
specific resource D) A country subsidizes its industries to make them more competitive globally
ANSWERB
• Rationale for A: Incorrect. This describes absolute advantage, not comparative advantage.
• Rationale for B: Correct. Comparative advantage exists when a country can produce a good at a
lower opportunity cost than trading partners, forming the basis for mutually beneficial trade.
• Rationale for C: Incorrect. Resource control relates to natural endowments or strategic
dominance, not the economic principle of comparative advantage.
• Rationale for D: Incorrect. Subsidies are a trade policy tool that may distort comparative
advantage rather than define it.
10. When a government imposes a price ceiling below the equilibrium price, what is the most likely
result? A) Surplus of the good B) Shortage of the good C) Increase in product quality D) Decrease in black
market activity
ANSWERB
• Rationale for A: Incorrect. A surplus occurs with a price floor above equilibrium, not a price
ceiling below equilibrium.
• Rationale for B: Correct. A binding price ceiling creates excess demand (quantity demanded
exceeds quantity supplied) at the controlled price, resulting in a shortage.
• Rationale for C: Incorrect. Price ceilings often reduce producer incentives, potentially leading to
lower quality, not higher.
• Rationale for D: Incorrect. Shortages from price ceilings typically increase, not decrease, black
market activity as consumers seek the good through unofficial channels.
