Chapter 1: Ten Principles of Economics
PURPOSE AND PERSPECTIVE OF THE CHAPTER
Chapter 1 is the first chapter in a three-chapter section that serves as the introduction to the text.
Chapter 1 introduces ten fundamental principles on which the study of economics is based. In a
broad sense, the rest of the text is an elaboration on these ten principles. Chapter 2 will develop
how economists approach problems while Chapter 3 will explain how individuals and countries
gain from trade.
The purpose of Chapter 1 is to lay out ten economic principles that will serve as building blocks for
the rest of the text. The ten principles can be grouped into three categories: how people make
decisions, how people interact, and how the economy works as a whole. Throughout the text,
references will be made repeatedly to these ten principles.
Key points addressed in this chapter:
The fundamental lessons about individual decision making are that people face trade-offs
among alternative goals, that the cost of any action is measured in terms of forgone
opportunities, that rational people make decisions by comparing marginal costs and
marginal benefits, and that people change their behavior in response to the incentives they
face.
The fundamental lessons about economic interactions among people are that trade and
interdependence can be mutually beneficial, that markets are usually a good way of
coordinating economic activity, and that the government can potentially improve market
outcomes by remedying a market failure or by promoting greater economic equality.
The fundamental lessons about the economy as a whole are that productivity is the ultimate
source of improving living standards, that growth in the quantity of money is the ultimate
source of inflation, and that society faces a short-run trade-off between inflation and
unemployment.
CHAPTER OBJECTIVES
The following objectives are addressed in this chapter:
Explain how scarcity influences decisions.
Explain how individuals evaluate opportunity costs to make decisions.
Explain how marginal analysis influences decision making.
Apply basic, economic principles of individual decision making that determine how an
economy generally works.
Explain how the terms of trade can lead to gains.
Given a scenario, identify the distribution system being used.

CHAPTER OUTLINE
The following outline organizes activities (including any existing discussion questions in
PowerPoints or other supplements) and assessments by chapter (and therefore by topic), so that
you can see how all the content relates to the topics covered in the text.
I. Introduction
A. The word “economy” comes from the Greek word oikonomos meaning “one who
manages a household.”
1. Instruction Idea: Begin by pointing out that economics is a subject that
students must confront in their daily lives. Point out that they already
spend a great deal of their time thinking about economic issues: changes in
prices, buying decisions, use of their time, concerns about employment,
etc.
B. Both households and economies face many decisions about how to allocate
resources.
C. Resources are scarce so they must be managed carefully.
