BACHELOR OF ARTS IN ECONOMICS Basic Economics w/ TAR Pangasinan State University Social Science Department – PSU Lingayen Market Equilibrium Market Equilibrium is a situation in which the quantity demanded of a good or service at a particular price is equal to the quantity supplied at that price.

BACHELOR OF ARTS IN ECONOMICS Basic Economics w/ TAR Pangasinan State University Social Science Department – PSU Lingayen Price as a Regulator The price of a good regulates the quantities demanded and supplied. If the price is too high, the quantity supplied exceeds the quantity demanded. If the price is too low, the quantity demanded exceeds the quantity supplied. There is one price at which the quantity demanded equals the quantity supplied.

BACHELOR OF ARTS IN ECONOMICS Basic Economics w/ TAR Pangasinan State University Social Science Department – PSU Lingayen Equilibrium Price and Quantity Equilibrium price is the price at which the quantity of a product demanded by consumers the quantity supplied by producers are equal. The quantity bought and sold at that price is the equilibrium quantity. The equilibrium price is also known as the market-clearing price: it is the price that “clears the market” by ensuring that every buyer willing to pay that price finds a seller willing to sell at that price, and vice versa.

BACHELOR OF ARTS IN ECONOMICS Basic Economics w/ TAR Pangasinan State University Social Science Department – PSU Lingayen Surplus, Shortage, and Equilibrium The market may experience a surplus (excess supply), which is the result of quantity supplied being greater than quantity demanded, usually because prices are too high. Or a shortage (excess demand) may occur, the result of quantity demanded being greater than quantity supplied, usually because prices are too low.

When consumers want more or producers supply less, prices will rise. Change in Supply and Demand and Equilibrium Price
