Market Demand
Definition
Market demand refers to the aggregate quantity of a good or service that all consumers in a market are willing and able to purchase at various prices during a given period. It is the sum of individual demands from consumers at each price level, providing a comprehensive view of the overall market demand.
Examples
- Automobile Industry: In the automobile market, the total number of cars that all consumers are willing to buy at different price points represents the market demand for automobiles. If the price of a car drops, the total number of cars demanded may increase, reflecting higher market demand.
- Electronic Goods: For a product like smartphones, market demand involves summing up the demand of all potential buyers in a region. A significant price cut by a leading brand may spike the market demand drastically.
- Food Products: The market demand for a basic commodity like wheat can be calculated by adding up the quantities demanded by households, bakeries, restaurants, and other businesses at various price levels.
