Question: In the chapter, most of the taxes we discussed were equal to a certain dollar amount per unit. In this case, a tax on sellers results in a parallel upward shift of the supply curve; a tax on buyers results in a parallel downward shift of the demand curve. In reality, however, many taxes are expressed as a percentage. Graphically, how would you show a 100% tax on the sellers of a good? How would you show a 100% tax on the buyers of a good? One of the results of this chapter is that it doesn't matter on whom the tax is levied; the result is the same. Show graphically that this also applies to percentage taxes.
