“Economics is a study of mankind in the ordinary business of life.” -Alfred Marshall

Scarcity Resources are scarce, so people face tradeoffs Time, income, the number of miles of beachfront property, etc. The real limit is the scarcity of productive resources (factors of production) Society has unlimited wants in the face of limited resources
