1 What is economics?

2 Economic choices We are faced with choices because we do not have enough productive resources to satisfy all of our wants and needs.

3 Economics: the study of how we make decisions in a world where resources are limited.

4 Need or want? Wants Needs Required for survival
Things we would like to have

5 The fundamental economic problem is scarcity (when we do not have enough resources to produce all of the things we would like to have).

Variable costs change w/the amount produced
