Equilibrium occurs when supply and demand coordinate to set prices and production.

Market equilibrium is achieved when supply and demand are equal. This would happen when prices and production are maintained at levels where demand and supply remain consistent. Economic theory proposes that there is a particular price for a product or service which brings demand and supply into balance, which economists term the equilibrium price. In typical markets, equilibrium is not achieved as a constant state of affairs. Rather, supply and demand will fluctuate around what would be the theoretical equilibrium price. If prices rise due to high demand, this signals producers to expand production to meet the demand for greater supply. If there is too much supply available, market prices will drop as suppliers work to sell their surpluses.
