What does the Laffer Curve suggest about tax revenue and tax rates?

• A. A direct relationship with no optimum.
• B. There is no relation between tax rate and revenue.
• C. Optimum tax rate maximizing revenue exists.
• D. It describes the relationship between inflation and unemployment.

Answer: (C)

The key idea is that tax revenue does not rise indefinitely as tax rates increase. The Laffer Curve shows that revenue is low at very low rates, climbs as rates rise, but after a certain point higher rates reduce the tax base (people work less, invest less, evasion grows, or money moves underground), so total revenue falls. This creates an optimal tax rate where revenue is maximized. The exact peak depends on how responsive people and the economy are to tax changes. So the best choice is that there exists an optimum tax rate maximizing revenue. The other ideas—revenue always rising with rate, no relation between rate and revenue, or linking tax to inflation/unemployment—don’t fit the concept described by the Laffer Curve.
