a market in which there are many buyers and sellers of the same good or service, none of whom can influence the price at which the good or service is sold
the price at which the market is in equilibrium, that is, the quantity of a good or service demanded equals the quantity of that good or service supplied; also referred to as the equilibrium price.
a graphical representation showing the relationship between quantity supplied and price
the actual amount of a good or service consumers are willing to buy at some specific price
a list or table showing how much of a good or service producers will supply at different prices
a graphical representation of the relationship between quantity demanded and price for an individual consumer
a graphical representation of the demand schedule, showing the relationship between quantity demanded and price
a change in the quantity demanded at any given price, represented by the change of the original demand curve to a new position, denoted by a new demand curve
a change in the quantity supplied of a good or service at any given price, represented graphically by the change of the original supply curve to a new position, denoted by a new supply curve
a good or service used to produce another good or service
the actual amount of a good or service producers are willing to sell at some specific price
pairs of goods for which a rise in the price of one of the goods leads to an increase in the demand for the other good
a good for which a rise in income decreases the demand for the good
the principle that a higher price for a good or service, other things equal, leads people to demand a smaller quantity of that good or service
the insufficiency of a good or service that occurs when the quantity demanded exceeds the quantity supplied; shortages occur when the price is below the equilibrium price.
a change in the quantity supplied of a good that results from a change in the price of that good
pairs of goods for which a rise in the price of one good leads to a decrease in the demand for the other good
a good for which a rise in income increases the demand for that good—the “normal” case
a model of how a competitive market works
illustrates the relationship between quantity supplied and price for an individual consumer
the quantity of a good or service bought and sold at the equilibrium (or marketclearing) price.
the price at which the market is in equilibrium, that is, the quantity of a good or service demanded equals the quantity of that good or service supplied; also referred to as the marketclearing price.
a change in the quantity demanded of a good that results from a change in that good’s price
shows how much of a good or service consumers will want to buy at different prices
the excess of a good or service that occurs when the quantity supplied exceeds the quantity demanded; surpluses occur when the price is above the equilibrium price.
