DEFINITION of 'Law Of Supply And Demand'. A theory explaining the interaction between the supply of a resource and the demand for that resource. The law of supply and demand defines the effect that the availability of a particular product and the desire (or demand) for that product has on price. Generally, if there is a low supply and a high demand, the price will be high.
Supply and demand curves express relationships between price and quantity. Equilibrium exists when supply equals demand. The shape of these curves and the equilibrium price affect small and large businesses because revenues are a factor of price and quantity. Although a single business cannot affect the shape of these curves, the combined actions of businesses and consumers affect the supply and demand curves for different industries.
