Instructor Solution Manual For Essentials of Economics, 9th Edition N. Gregory Mankiw Chapter 1-24
TEN PRINCIPLES OF ECONOMICS WHAT’S NEW IN THE NINTH EDITION: There are no major changes to this chapter.
LEARNING OBJECTIVES: By the end of this chapter, students should understand:
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.
CONTEXT AND PURPOSE: 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.
