In a market economy, supply is the amount of a specific good or service that producers or sellers are willing and able to offer to buyers at various prices during a given time period. It represents the quantity of goods or services available in the market for consumption and generally increases as the price rises, since higher prices incentivize producers to supply more to maximize profits. Supply is depicted by the supply curve, which typically slopes upward showing the relationship between price and quantity supplied. It is a fundamental concept that works together with demand to determine market equilibrium, where the quantity supplied equals the quantity demanded.
