Suppose that the U.S. government decides to charge cola producers a tax. Before the tax, 50 million cases of cola were sold every month at a price of $7 per case. After the tax, 44 million cases of cola are sold every month; consumers pay $10 per case, and producers receive $4 per case (after paying the tax).
