Theme 1: Introduction to Economics & Key Concepts
1. What is the fundamental economic problem that all societies face?
A) High taxes
B) Environmental pollution
C) Scarcity
D) Lack of technological innovation
ANSWER: C) Scarcity
Explanation: Scarcity means that human wants for goods, services, and
resources exceed what is available. This unending condition forces societies to
make choices about how to allocate limited resources, forming the basis of all
economic study.
2. Economics is best defined as the study of:
A) How to run a business profitably
B) How governments can influence money supply
C) How societies allocate scarce resources to satisfy unlimited wants
D) Stock market trends and investments
ANSWER: C) How societies allocate scarce resources to satisfy unlimited
wants
Explanation: This is the classic and most comprehensive definition of
economics, encompassing both micro and macro levels of decision-making
under scarcity.
3. The concept of "opportunity cost" refers to:
A) The financial cost of a good or service
B) The cost of the next best alternative forgone when a choice is made
C) The cost of finding a business opportunity
D) The sunk cost of a failed investment
,ANSWER: B) The cost of the next best alternative forgone when a choice is
made
Explanation: Opportunity cost is a cornerstone concept. It's not about the
monetary price, but the value of what you could have had if you had chosen
differently. For example, the opportunity cost of studying is the leisure time you
give up.
4. A positive economic statement is:
A) A claim about what ought to be.
B) Always true and optimistic.
C) A claim that can be tested against factual evidence.
D) A value judgment.
ANSWER: C) A claim that can be tested against factual evidence.
Explanation: Positive statements are objective and fact-based. They describe
"what is." For example, "An increase in the minimum wage will lead to higher
unemployment" is a positive statement (whether it's true or false is testable).
5. A normative economic statement is:
A) Based on empirical evidence.
B) A claim about what ought to be, often involving value judgments.
C) Never used in policy debates.
D) The same as a positive statement.
ANSWER: B) A claim about what ought to be, often involving value
judgments.
Explanation: Normative statements are subjective and based on opinions or
values. For example, "The government should raise the minimum wage" is a
normative statement.
6. The three primary questions every economic system must answer are:
A) What, How, and Why to produce?
B) What, How, and For Whom to produce?
C) When, Where, and How to produce?
D) Why, When, and For Whom to produce?
ANSWER: B) What, How, and For Whom to produce?
Explanation: These questions address the allocation of output (What goods and
, services?), the allocation of inputs (How are they produced?), and the
distribution of output (Who gets to consume them?).
7. The additional benefit resulting from a one-unit increase in an activity is
the:
A) Marginal Cost
B) Total Benefit
C) Average Benefit
D) Marginal Benefit
ANSWER: D) Marginal Benefit
Explanation: "Marginal" means extra or additional. Marginal Benefit (MB) is
the increase in total benefit from one more unit.
8. The additional cost resulting from a one-unit increase in an activity is the:
A) Marginal Cost
B) Total Cost
C) Average Cost
D) Sunk Cost
ANSWER: A) Marginal Cost
Explanation: Similarly, Marginal Cost (MC) is the increase in total cost from
producing one more unit.
9. Rational decision-makers will continue an activity up to the point where:
A) Total Benefit is maximized.
B) Marginal Benefit equals Marginal Cost (MB = MC).
C) Marginal Benefit is greater than Marginal Cost.
D) Total Cost is minimized.
ANSWER: B) Marginal Benefit equals Marginal Cost (MB = MC).
Explanation: If MB > MC, the activity is worth doing. If MC > MB, it is not. The
optimal point is where the last unit provides a benefit just equal to its cost.
10. A cost that has already been incurred and cannot be recovered is a:
A) Marginal Cost
B) Variable Cost
C) Sunk Cost
D) Opportunity Cost
