If the market price for wheat is below the ceiling, say $200 in this example, then the ceiling has no effect on prices; the ceiling is not binding.f it were above the equilibrium price it would not be binding because the market would reach equilibrium and the ceiling would have no effect. A price floor is binding when it is above the equilibrium price.
