About This Exam
The CLEP Principles of Microeconomics exam covers material typically taught in a one-semester introductory microeconomics course at the college level. It tests your understanding of how individual consumers and firms make decisions, how markets function, and the role of government in the economy.
What's Covered
- Supply and demand — how prices and quantities are determined in competitive markets, shifts vs. movements along curves, and equilibrium
- Elasticity — price elasticity of demand and supply, income elasticity, cross-price elasticity, and their applications to tax incidence and consumer behavior
- Consumer choice — utility theory, budget constraints, indifference curves, and how consumers maximize satisfaction
- Production and costs — short-run vs. long-run production, marginal product, diminishing returns, fixed and variable costs, economies of scale
- Market structures — perfect competition, monopoly, monopolistic competition, and oligopoly, including profit maximization and pricing behavior in each
- Factor markets — labor demand and supply, wage determination, marginal revenue product
- Market failure and government intervention — externalities, public goods, price controls, taxes, subsidies, and antitrust policy
For the official exam description, see the College Board CLEP Microeconomics page.
Study Tips
- Master supply and demand graphs first. They appear throughout the exam and form the foundation for nearly every other topic.
- Know the differences between market structures cold — how firms set prices, the number of firms, barriers to entry, and long-run profit outcomes for each.
- Practice calculating elasticity, consumer and producer surplus, and deadweight loss. These are common quantitative questions.
- Understand marginal analysis — marginal cost equals marginal revenue is the profit-maximizing rule that applies across all market structures.
- Don't confuse accounting profit with economic profit. The exam tests this distinction directly.

- A) 0.5 tons of wheat
- B) 1 ton of wheat
- C) 2 tons of wheat
- D) 50 tons of wheat
- E) 100 tons of wheat
View Answer & Explanation
Correct Answer:
C) 2 tons of wheat
Explanation:
If the country can produce 100 wheat or 50 steel, giving up 50 steel means gaining 100 wheat. So 1 steel = 100/50 = 2 wheat. The opportunity cost of one ton of steel is 2 tons of wheat.
- A) An increase in unemployment
- B) A decrease in immigration
- C) An advance in technology
- D) An increase in consumer spending
- E) A decrease in government regulation
View Answer & Explanation
Correct Answer:
C) An advance in technology
Explanation:
An advance in technology increases the economy's productive capacity, shifting the PPC outward. Unemployment changes move along the PPC but don't shift it. Changes in spending or regulation don't directly expand productive capacity.
- A) Country A has a comparative advantage in wine production
- B) Country B has a comparative advantage in cloth production
- C) Country A has a comparative advantage in cloth production
- D) Neither country has a comparative advantage in either good
- E) Country B has an absolute advantage in both goods
View Answer & Explanation
Correct Answer:
C) Country A has a comparative advantage in cloth production
Explanation:
Country A's opportunity cost of cloth is 2/6 = 1/3 wine, while B's is 4/4 = 1 wine. Since 1/3 < 1, Country A has a lower opportunity cost for cloth and thus a comparative advantage in cloth production.
- A) considering only the total benefits of an action
- B) comparing the additional benefits and additional costs of an action
- C) evaluating all possible alternatives before choosing
- D) ignoring costs that have already been incurred
- E) maximizing total revenue regardless of cost
View Answer & Explanation
Correct Answer:
B) comparing the additional benefits and additional costs of an action
Explanation:
Marginal analysis involves comparing the marginal (additional) benefit of an action to its marginal (additional) cost. Rational decision-makers continue an activity as long as the marginal benefit exceeds the marginal cost.
- A) Government planning agencies
- B) Labor unions
- C) Consumer preferences expressed through market demand
- D) The stock market
- E) International trade agreements
View Answer & Explanation
Correct Answer:
C) Consumer preferences expressed through market demand
Explanation:
In a market economy, consumer sovereignty drives production decisions. Firms produce goods and services that consumers demand because that is where profit opportunities exist.
