Supply and demand is perhaps one of the most fundamental concepts of economics and it is the backbone of a market economy. Demand refers to how much (quantity) of a product or service is desired by buyers. The quantity demanded is the amount of a product people are willing to buy at a certain price; the relationship between price and quantity demanded is known as the demand relationship. Supply represents how much the market can offer.
A: Supply and demand expresses a relationship between what producers supply and what consumers demand in economics. Aggregate supply and demand is the total supply and total demand in an economy at a particular period of time and particular price threshold. A curve is used to graph the aggregate supply and aggregate demand. These curves illustrate the relationships among price points, time, supply, and demand levels.
