The term for that definition is effective demand
Demand
Demand is considered what consumers are willing and able to buy. If the product or service is too expensive, then people won't buy it because they can't afford it and there will be no demand. If it's affordable but people don't see the use, they still won't buy it and there will still be no demand. In order to create demand, a product has to be both useful and affordable. The more useful and affordable it is, the more demand there will be.
Consumer surplus
The term defined as an item or feature for which a consumer is willing to pay is called a "value proposition." This concept encompasses the benefits and features that make a product or service attractive to consumers, justifying their willingness to spend money. A strong value proposition clearly communicates how a product meets the needs or solves the problems of the target audience.
When demand exceeds the amount of resources, the result is called a shortage. This occurs when the quantity of a good or service available is insufficient to meet the desire for it, leading to unmet consumer needs. Shortages can lead to increased prices, competition for the limited resources, and potential market inefficiencies.
