What does it mean if a point is inside the PPF?

A point inside the PPF indicates a waste of resources.

What does a bowed shape of the PPF indicate?

A bowed shape indicates rising opportunity costs as more of one good is produced.

What is the Circular Flow Diagram?

The Circular Flow Diagram shows how money, goods, and services move in the economy between households and firms.

Money flows from households to firms when households spend and from firms to households when firms pay wages.
