Asked by Jean

what is meant by the term"utility" and how does the idea relate to purposeful behavior?
Answered by economyst
Utility is relative measure of happiness/pleasure/satisfaction.

See http://en.wikipedia.org/wiki/Utility

If consuming good A gives a person more utility than good B, then that person would pay more for A than B.
