SECTION 1: INTRODUCTION AND ECONOMIC REASONING (CHAPTER 1)




Question 1
The answers to an economy's three central economic problems are determined
by the interaction of which three forces?
A) Economic, political, and social forces
B) Market, command, and traditional forces
C) Supply, demand, and equilibrium forces
D) Domestic, international, and fiscal forces


Answer: A
Explanation: The three central coordination problems—what, how, and for
whom to produce—are determined by the interaction of economic forces (like
prices), political forces (like laws), and social forces (like customs)
[citation:1][citation:4].


Question 2
Scarcity exists because:
A) Economies cannot produce enough to meet the perceived desires of all
individuals.

1

,B) There is an unequal distribution of wealth.
C) Governments interfere with market outcomes.
D) People are inherently greedy.


Answer: A
Explanation: Scarcity is the fundamental economic problem that arises because
human wants for goods and services exceed the available productive capacity.
It is not about inequality or greed, but about the finite nature of resources
[citation:1].


Question 3
The economic decision rule can be summarized as:
A) Undertake an action only if its total benefits are greater than its total costs.
B) Undertake an action only if its marginal benefits are greater than its marginal
costs.
C) Always follow the rules set by political and social forces.
D) Undertake an action only if past costs (sunk costs) can be recovered.


Answer: B
Explanation: The economic decision rule for rational actors is to take an action
only if the additional (marginal) benefits outweigh the additional (marginal)
costs. Sunk costs should be ignored [citation:1][citation:4].


Question 4
The "invisible hand" refers to:
A) Government regulation of markets.
B) The price mechanism that guides people's self-interested actions to produce
socially beneficial outcomes.
C) The role of luck in economic success.
D) The study of microeconomics.

, Answer: B
Explanation: A concept introduced by Adam Smith, the "invisible hand"
describes how individuals pursuing their own self-interest in free markets can
unintentionally promote the good of society as a whole, guided by prices and
competition [citation:1].


Question 5
Which statement is TRUE regarding marginal and sunk costs?
A) Only marginal costs, not sunk costs, affect rational economic decisions.
B) Only sunk costs, not marginal costs, affect rational economic decisions.
C) Both marginal and sunk costs should be equally considered in rational
decision-making.
D) Neither marginal nor sunk costs have any impact on rational decisions.


Answer: A
Explanation: Sunk costs are costs that have already been incurred and cannot
be recovered. Rational decision-making focuses on marginal costs (the cost of
the next unit) and ignores sunk costs, as they are irrelevant to the future
[citation:1][citation:4].


Question 6
The study of the economy as a whole, including topics like inflation,
unemployment, and economic growth, is known as:
A) Microeconomics
B) Normative economics
C) Macroeconomics
D) Positive economics


Answer: C
Explanation: Macroeconomics looks at the big picture—the performance,
structure, and behavior of the entire economy. Microeconomics studies
individual choices and markets [citation:1].
