Shortage:A shortage occurs when the quantity demanded exceeds the quantity supplied at the current market price, leading to an imbalance between supply and demand.
Equilibrium:Equilibrium is the state where the quantity supplied equals the quantity demanded, resulting in a stable market price and no shortages or surpluses.
Price Ceiling:A price ceiling is a legal limit on the maximum price that can be charged for a good or service, which can lead to an undersupply if the ceiling is set below the market equilibrium price.
