Price ceilings do not have much effect:
in nonmarket economies. in times of high inflation. when market prices are at or below the ceiling. ever.
Price ceilings do not have much effect when market prices are at or below the ceiling.
When the market price is already below the price ceiling, the ceiling does not restrict the market, and prices can continue to operate freely without any impact from the ceiling. In contrast, price ceilings can lead to shortages and other market distortions when they are set below the equilibrium price.
