PURPOSE AND PERSPECTIVE OF THE CHAPTER
This chapter has two purposes: to introduce students to some of the basic language of economics and to
stimulate student interest in the subject. It conveys to students that economics not only is found on
financial news websites, but also is very much a part of their everyday lives. Beginning with the
economic problem of scarce resources but unlimited wants, this chapter provides an overview of the field
and the analytical techniques used. Concepts introduced include resources, goods and services, the
economic decision makers in the economy, and marginal analysis. Two models for analysis, the circular
flow model and steps of the scientific method, are introduced. The appendix introduces the use of graphs.

1.1 Explain how scarcity drives economic decision-making for individuals, businesses, and
governments.
1.2 Contrast macroeconomic concepts versus microeconomic concepts.
1.3 Explain the importance of the other things constant (ceteris paribus) assumption in economic
theory and models.
1.4 Distinguish between positive and normative economic analysis.
1.5 Using the circular flow model, illustrate how real-world economic transactions and interactions
