Microeconomics

If a tax is levied on the sellers of sugar, then

buyers and sellers will share the burden of the tax

Price ceilings and price floors that are binding

cause surpluses and shortages to persist since price cannot adjust to the market equilibrium price

When a binding price floor is imposed on a market,

price no longer serves as a rationing device, the quantity supplied at the price floor exceeds the quantity that would have been supplied without the price floor, and only some sellers benefit.

Suppose the equilibrium price of a physical examination ("physical") by a doctor is $200, and the government imposes a price ceiling of $150 per physical. As a result of the price ceiling,

the quantity demanded of physicals increases and the quantity supplied of physicals decreases

If a price ceiling is not binding, then

there will be no effect on the market price or quantity sold.
