Equilibrium Equilibrium is the price and quantity at which the quantity supplied and the quantity demanded are equal. A market is said to be in disequilibrium at all points at which the quantities demanded and supplied are not equal. ◦A surplus occurs whenever Qs>Qd. ◦A shortage occurs whenever Qd>Qs. ◦Surpluses and shortages can be resolved with price changes. © 2016 CENGAGE LEARNING.
