Sample Question
What is the relationship between needs, wants, and scarcity in economics?

Limited. Society has just enough resources to meet its needs but not its wants.

Abundant. Society has unlimited resources to produce and satisfy all its needs and wants.

Scarce. The desire of society (individual consumers, government, business) to obtain and use goods and services is unlimited and the objective of all economic activity is to satisfy these material wants. The problem lies in the fact that economic resources (land, capital, labor, enterprise) are limited or scarce and therefore society will not be able to produce and consume all the goods and services it wants. Economics, then, is the science of efficiency; concerned with allocating these scarce resources so as to achieve maximum fulfillment of our material wants.

Unlimited. Society can produce and consume all the goods and services it desires without any constraints.
