Definition of Demand
Demand is an economic concept that represents a consumer’s desire to purchase goods and services, coupled with their willingness to pay a specific price for them. Essentially, demand is the relationship between how much of a good consumers want and the price they’re willing to pay. According to the law of demand, when the price of a good or service increases, the quantity demanded generally decreases, and when the price decreases, the quantity demanded typically increases.
| Demand | Supply |
|---|---|
| Represents consumer desire | Represents producer willingness |
| Law of Demand: Price ↔ Quantity | Law of Supply: Price ↔ Quantity |
| Affects market prices | Interacts with demand to set prices |
| Driven by consumer preferences | Driven by production costs |
Examples of Demand
-
Market Demand: The total quantity of coffee consumers are willing to buy from various suppliers at different prices. For instance, at a price of $2 per cup, consumers might demand 100 cups, whereas they might only demand 50 cups if the price rises to $4.
-
Aggregate Demand: The total demand for all goods and services in an economy at a given price level. For example, when consumers generally have more money due to lower taxes, aggregate demand tends to increase.
Related Terms
- Elasticity of Demand: Measures how much the quantity demanded of a good responds to changes in other factors like price. A “price-elastic” demand means consumers will significantly reduce purchasing if prices rise.
- Cross Elasticity of Demand: Measures how the demand for one product is affected by the price change of another product, such as how the demand for butter might change with the price of margarine.
