Understand the concept of a price ceiling: it is a legal maximum price that sellers can charge for a good or service.
Recall that the equilibrium price is where the quantity demanded equals the quantity supplied in a free market without intervention.
Recognize that if a price ceiling is set above the equilibrium price, it is non-binding and does not affect the market because the market price is already lower.
Note that if a price ceiling is set at the equilibrium price, the market clears normally, so it has no effect.
Identify that a binding price ceiling must be set below the equilibrium price, which prevents prices from rising to the equilibrium level and makes it illegal to charge a higher price.
