EXAMINATION (250 QUESTIONS)
1. Microeconomics is fundamentally concerned with the study of how individuals
and firms make decisions regarding the allocation of resources, which are
inherently limited. This core concept is best defined as the study of:
A) The distribution of wealth among different socioeconomic classes.
B) The allocation of scarce resources among competing uses.
C) The overall performance and growth of the national economy.
D) The regulation of financial markets and international trade.
Correct Answer: B
Rationale: Microeconomics studies the allocation of scarce resources. Scarcity is the
fundamental problem that drives economic decision-making at the individual and firm
level, requiring choices about how to allocate limited resources to satisfy unlimited
wants.
2. A primary topic of inquiry for microeconomics involves the analysis of how
prices are determined and how they influence the decisions of buyers and sellers.
Because of this focus, microeconomics is frequently referred to as:
A) Decision science.
B) Price theory.
C) Resource theory.
D) Market dynamics.
Correct Answer: B
Rationale: Microeconomics is often called price theory because it examines how prices
are set in markets and how these prices allocate scarce resources. The interaction of
supply and demand determines equilibrium prices, which guide the decisions of
consumers and producers.

3. A foundational assumption of most microeconomic models is that decision-
makers, whether consumers or firms, act in a manner that reflects their own best
interests. What is the standard term for this assumption?
A) They act to maximize their own well-being or profits.
B) They act to benefit society as a whole.
C) They act randomly without a clear objective.
D) They act to minimize their costs regardless of outcome.
Correct Answer: A
Rationale: Most microeconomic models assume that decision makers wish to make
themselves as well off as possible. Consumers maximize utility, while firms maximize
profit. This assumption of rational self-interest is a cornerstone of economic modeling.
4. The concept of scarcity is fundamental to economics because it forces society
to make choices, which inevitably leads to trade-offs. Society faces these trade-
offs primarily because of:
A) Government regulations and bureaucratic oversight.
B) The profit motive of private corporations.
C) The existence of faceless bureaucrats.
D) Scarcity of resources relative to human wants.
Correct Answer: D
Rationale: Society faces trade-offs because of scarcity. Since resources are limited,
choosing to produce more of one good means producing less of another. This trade-off
is the fundamental economic problem.
5. A market is the institutional mechanism that facilitates transactions between
buyers and sellers. Which of the following best describes the essential function of
a market?
A) It ensures that all participants earn a fair profit.
B) It allows interactions between consumers and firms.
C) It provides physical locations for all transactions.
D) It sets legal prices for all goods and services.
Correct Answer: B
Rationale: A market is any arrangement that allows interactions between consumers
and firms. These interactions can occur in physical locations, online, or through other
mechanisms. Markets do not necessarily require face-to-face exchange or physical
locations.
6. The decisions of consumers and firms are coordinated in a market economy
primarily through a mechanism that conveys information about relative scarcity.
This coordinating mechanism is:
A) Government planning.
, Page 3 of 65
B) Prices.
C) Coordination officials.
D) Central banking.
Correct Answer: B
Rationale: Prices link the decisions of consumers and firms in a market. Prices serve as
signals that convey information about scarcity and value, guiding both consumption
and production decisions to equilibrate supply and demand.
7. The price of a good or service serves as a key signal in a market economy. The
price of a good is:
A) Always equal to the cost of producing it.
B) Never affected by the number of buyers and sellers.
C) Usually determined in a market.
D) Fixed by government decree.
Correct Answer: C
Rationale: The price of a good is usually determined in a market through the interaction
of supply and demand. While production costs influence supply, the final price is
determined by the equilibrium between buyers' willingness to pay and sellers'
willingness to sell.
8. In the United States, the coordination of scarce resources to produce goods and
services is primarily accomplished through which mechanism?
A) The U.S. government.
B) The United Nations.
C) The Federal Reserve Bank.
D) Markets and prices.
Correct Answer: D
Rationale: Markets and prices are responsible for bringing together scarce resources to
produce most goods and services in the U.S. The decentralized price system
coordinates the actions of millions of consumers and producers without central
direction.
9. Microeconomics addresses a wide range of decisions made by firms and
individuals. Which of the following is a fundamental topic addressed by
microeconomics?
A) Whether to extend unemployment insurance benefits.
B) Determining how many new iPhones the Apple company should produce.
C) The level of inflation in the country.
D) The impact of interest rates on national savings.
, Page 4 of 65
Correct Answer: B
Rationale: Microeconomics focuses on individual decision-makers. Determining
production levels for a specific firm like Apple is a microeconomic question involving
cost, demand, and profit maximization. Unemployment insurance, inflation, and
national savings are macroeconomic topics.
10. A proposed "twinkie tax" on fatty foods would serve multiple purposes. The tax
would aim to:
A) Reduce the consumption of fatty foods.
B) Reduce the production of fatty foods.
C) Raise tax revenues for other uses.
D) All of the above.
Correct Answer: D
Rationale: A tax on fatty foods would aim to reduce consumption and production (by
making them more expensive) while also generating tax revenue. This illustrates how
government policy can influence both economic behavior and government finances.
11. After Clark Foam shut down in 2005, eliminating 80% of the world's foam blanks
used to shape surfboards, surfboard manufacturers faced a significant trade-off.
The firms decided to:
A) Substitute foam blanks for balsa wood blanks as used in the 1940s.
B) Advertise their new surfboard wax.
C) Offer surf classes.
D) B and C.
Correct Answer: A
Rationale: This illustrates the trade-off firms face when a key input becomes
unavailable. Manufacturers had to decide between alternative inputs. Substituting
balsa wood for foam is a production decision necessitated by scarcity and changing
relative prices.
12. In the Soviet Union, where full employment was guaranteed, some workers
were assigned to dig holes and then fill them again. This policy highlights which
function of microeconomic analysis?
A) What goods and services to produce.
B) How to produce the goods and services.
C) Who gets the goods and services.
D) A and B.
Correct Answer: D
Rationale: The policy addressed both "what to produce" (the output of holes) and "how
to produce" (using labor to dig holes). This illustrates how centrally planned economies
