Question
If a tax on a good is doubled, the deadweight loss from
the taxSolution
If a tax on a good is doubled, the deadweight loss from the tax increases by a factor of four. Where a tax increases linearly, the deadweight loss increases as the square of the tax increase. This means that when the size of a tax doubles, the base and height of the triangle double. Thus, doubling the tax increases the deadweight loss by a factor of 4.
