ResourcesResources – anything used to satisfy wants or needs. [inputs]

Factors of productionFactors of production – building blocks (resources/inputs) used to produce products. They are inputs used when something is going to be made. There are thousands of inputs or factors of production, all of which can be

grouped under landland, laborlabor, or capitalcapital.

Needs – goods/services necessary for survival. [food, clothing, and shelter ] Wants – Goods/services consumed not necessary for survival. [car, soccer ball ]Scarcity – when resources do not satisfy wants and needs. [Wants are greater than resources.] [Scarcity makes decisions necessary & opportunity costs unavoidable.]
