What is the difference between binding and non-binding price ceilings?

A binding price ceiling is a legal maximum price set below the equilibrium price, leading to shortages because the quantity demanded exceeds the quantity supplied. In contrast, a non-binding price ceiling is set above the equilibrium price, meaning it has no effect on the market since the price naturally stays below the ceiling. Thus, while binding ceilings can disrupt market balance, non-binding ceilings do not impact pricing or supply-demand dynamics.
