Supply and Demand (Economics)
Supply and demand is a fundamental concept in economics that explains
how prices and quantities of goods are determined in a market. Demand
refers to how much of a product consumers are willing to buy at various
prices, while supply indicates how much producers are willing to sell.
The law of demand states that as price decreases, demand increases (and
vice versa). Conversely, the law of supply says that as price increases,
supply increases. The point where supply and demand meet is called the
equilibrium price—the price at which quantity supplied equals quantity
demanded.
Factors affecting demand include consumer income, tastes, and prices of
related goods. Supply can be influenced by production costs, technology, and
number of sellers. When either shifts, it changes the equilibrium.
Understanding supply and demand helps explain market behavior,
shortages, surpluses, and price changes.
