1. A consumer has limited income and must choose between two goods. Which
economic principle explains why choosing more of one good generally requires
giving up some of the other?
A. Marginal utility
B. Opportunity cost
C. Economies of scale
D. Price discrimination
Rationale: Opportunity cost is the value of the next-best alternative forgone when a choice is
made. Because income is limited, purchasing more of one good may require sacrificing
purchases of another.
2. Which statement best describes the central economic problem?
A. Firms always seek to maximize revenue. B. Governments must control all markets. C.
Consumers prefer lower prices to higher prices. D. Resources are scarce while human wants
are unlimited.
Rationale: Scarcity exists because available resources are limited relative to unlimited wants.
Economics examines how individuals and societies allocate those scarce resources.
3. A student spends Saturday studying rather than working a job that would have
paid $80. The student also gives up a recreational activity worth $20 to them. If
studying is the chosen activity, what is the opportunity cost based on the best
alternative?
A. $80
B. $20
C. $100
D. $60
Rationale: Opportunity cost is determined by the value of the single next-best alternative
forgone, not the sum of every alternative that was sacrificed.
4. A production possibilities frontier is bowed outward from the origin primarily
because:
A. resources are unlimited. B. all resources are equally productive in every use. C. opportunity
costs tend to increase as production shifts toward one good. D. consumer preferences never
change.
,Rationale: A bowed-out production possibilities frontier reflects increasing opportunity cost.
Resources are not equally suited to producing different goods, so increasingly larger amounts of
one good must be sacrificed to produce additional units of another.
5. An economy is operating at a point inside its production possibilities frontier.
Which interpretation is most appropriate?
A. The economy has achieved maximum productive efficiency. B. The economy is producing
beyond its available resources. C. The economy must reduce production immediately. D. Some
available resources are unemployed or used inefficiently.
Rationale: Points inside the frontier indicate that the economy could produce more of at least
one good with its existing resources and technology.
6. Which change would most directly shift a country's production possibilities
frontier outward?
A. A decrease in labor productivity B. An improvement in production technology C. A
reduction in available resources D. An increase in unemployment
Rationale: Improved technology allows existing resources to produce more output, expanding
the economy's productive capacity and shifting the frontier outward.
7. In a market economy, the price system primarily helps coordinate decisions by:
A. eliminating scarcity. B. guaranteeing equal incomes. C. preventing firms from competing. D.
communicating information about relative scarcity and consumer demand.
Rationale: Prices provide signals to consumers and producers. Rising prices can indicate
increased demand or relative scarcity, influencing production and consumption decisions.
8. Which statement is a positive economic statement?
A. An increase in the minimum wage can affect employment in low-wage labor markets.
B. The government should increase the minimum wage. C. Income inequality is unacceptable. D.
Society ought to provide free public transportation.
Rationale: A positive statement is descriptive and can be tested using evidence. The other
statements contain normative judgments about what should or ought to happen.
9. Suppose the price of a product rises while consumers' incomes and preferences
remain unchanged. The movement from one point to another along the same
demand curve represents:
A. an increase in demand. B. a decrease in demand. C. a change in quantity demanded. D. a
change in consumer preferences.
, Rationale: A change in the product's own price causes movement along the existing demand
curve, changing quantity demanded rather than shifting demand.
10. Which factor would cause the demand curve for a normal good to shift to the
right?
A. A decrease in the good's own price B. A decrease in consumer income C. An increase in the
good's own price D. An increase in consumer income
Rationale: For a normal good, higher income increases demand at each possible price, shifting
the demand curve to the right.
11. Coffee and tea are substitutes. If the price of coffee increases while other factors
remain constant, what is most likely to happen in the market for tea?
A. The demand for tea decreases. B. The demand for tea increases. C. The supply of tea
decreases. D. The quantity supplied of tea becomes zero.
Rationale: When the price of a substitute rises, consumers tend to switch toward the relatively
cheaper alternative. Therefore, demand for tea increases.
12. Printers and ink cartridges are commonly treated as complementary goods. If the
price of printers falls substantially, what is the likely effect on the demand for ink
cartridges?
A. Demand for ink cartridges decreases. B. Supply of ink cartridges decreases. C. The price of
ink cartridges must fall. D. Demand for ink cartridges increases.
Rationale: Complementary goods are consumed together. A lower printer price can increase
printer purchases, which increases demand for associated ink cartridges.
13. Which event would most likely shift the supply curve for a manufactured product
to the right?
A. A reduction in the cost of raw materials
B. An increase in wages paid to workers C. An increase in business taxes D. A disruption that
reduces available machinery
Rationale: Lower input costs reduce the cost of production, allowing producers to supply more
at each price and shifting supply to the right.
14. A technological improvement allows firms to produce the same quantity of output
using fewer inputs. What happens to market supply, assuming other conditions
remain unchanged?
A. Supply shifts left. B. Quantity demanded falls. C. Supply shifts right. D. Demand shifts left.
