Price Ceilings


Price Ceiling: a government law that makes it illegal to charge higher than the specified price.


Two things can happen when a price ceiling is implemented.


Case 1: The price ceiling is above  the equilibrium price. In this case there is no effect on anything, and the equilibrium price and quantity stay the same.


Price ceiling above equilibrium price

Case 2: The price ceiling is below  the equilibrium price. In this case, there will be an underproduction of the quantity supplied, and a higher willingness to pay from consumers. This decreases the economic surplus and creates deadweight loss.


Price ceiling below equilibrium price

Problems with Rent Ceiling
  1. Shortage of Housing
  2. Creates a Black Market
  3. Increased Search Activity
