In economics, demand is the quantity of a good that consumers are willing and able to purchase at various prices during a given time. [1][2] In economics "demand" for a commodity is not the same thing as "desire" for it. It refers to both the desire to purchase and the ability to pay for a commodity. [2]
Economists use the term demand to refer to the amount of some good or service consumers are willing and able to purchase at each price. Demand is based on needs and wants—a consumer may be able to differentiate between a need and a want, but from an economist’s perspective, they are the same thing. Demand is also based on ability to pay.
Demand = Desire + Willingness to pay for it + Ability to pay for it. In economics, demand refers to the quantity of a good or service that a consumer is willing and able to buy at different prices during a given period of time. It’s important to note that desire alone does not constitute demand.
