If a price ceiling is binding, then
there will be a shortage in the market the equilibrium price is above the price ceiling
If a price floor is binding, then
there will be a surplus in the market the equilibrium price is below the price floor
If a price floor is not binding, then
there will be no effect on the market price or quantity sold. the equilibrium price is above the price floor
If a price ceiling is not binding, then
there will be no effect on the market price or quantity sold. the equilibrium price is below the price ceiling
Economists typically measure efficiency using
