Why can a maximum price leave some buyers without a purchase?
A maximum permitted price can look like a direct route to affordability. In a simple supply-and-demand model, a ceiling below the equilibrium price leaves quantity demanded greater than quantity supplied. That model explains one mechanism; evaluating an actual policy also requires its rules, market conditions, and evidence about its effects.
Questions you could explore
- When would a price ceiling not change the model’s outcome?
- What would a real policy evaluation need beyond the diagram?
