What is the concept of supply and demand?

The concept of supply and demand fundamentally refers to the interaction between the availability of a product (supply) and the desire for that product (demand) in a market. Supply indicates how much of a product or service a producer is willing to sell at various price levels, while demand reflects how much of that product or service consumers are willing to purchase at those prices.

When demand increases and supply remains constant, prices tend to rise, as consumers compete to acquire the limited quantity available. Conversely, if supply increases while demand remains constant, prices may fall because the market may be saturated. This interplay helps to determine the equilibrium price, which is where the quantity demanded equals the quantity supplied.

Understanding this relationship is crucial for analyzing market dynamics, as it influences everything from pricing strategies to consumer behavior. Hence, the description of the relationship between availability and desire for products encapsulates the essence of supply and demand.
