full_question: James Tobin proposed creating one of these policies after the Bretton Woods conference to reduce exchange rate volatility.

A "lump-sum" variety of these policies may be progressive or regressive depending on what is used to calculate the effect of this policy. Types of these policies include Pigovian, value-added, and income. For 10 points, name these policies enacted by the government to raise revenue.
