Question

Quizplus · Accepted Answer

The problem with using a Clarke tax to finance government provision of a public good is that the revenues collected from the tax may not be sufficient to cover the cost of the public good. This means that the government may have to supplement the revenues collected from the tax with other sources of funding, which could be inefficient or unfair.
