Why It Matters

Have you ever wanted to buy something or to participate in an activity, but you couldn’t because you didn’t have enough income or time? How do scarce resources like time and income affect you and everyone around you? In this chapter, read to learn about what economics is and how it is part of your daily life.

Section 1. The basic problem in economics

Starting at a very young age, many Americans use the words want and need interchangeably. How often do you think about what you “want”? How many times have you said that you “need” something?

The Problem of Scarcity

Main idea: Scarcity exists because people’s incomes and time are limited.

Economics & YouIf you were very wealthy, would your resources be unlimited? Read on to learn why scarcity exists for everyone.

The need to make choices arises because everything that exists is limited, although some items (such as trees in a large forest) may appear to be in abundant ____12____. At any single moment, a fixed amount of resources is ____13____. At the same time, people have competing uses for these resources. This situation results in scarcity—the basic problem of economics.
