Equilibrium price is the market-clearing price where demand equals supply. It is determined by finding the intersection point on a graph where both curves intersect.
Picture yourself on an escalator with people going up (demand) and people going down (supply). At some point, they meet and are in balance. That meeting point represents the equilibrium price.
Surplus: Occurs when the quantity supplied exceeds the quantity demanded at a given price, resulting in excess supply.
Shortage: Occurs when the quantity demanded exceeds the quantity supplied at a given price, resulting in excess demand.
Price Ceiling: A government-imposed maximum price that can be charged for a good or service, often leading to shortages.
