Laffer curve

Laffer curve,

Definition of Laffer curve:

  1. A supposed relationship between economic activity and the rate of taxation that suggests the existence of an optimum tax rate that maximizes tax revenue.

  2. Graphical representation of a conceptual relationship between marginal tax rates and total tax collections. Named after the US economics professor Arthur Laffer who proposed that lower taxes encourage additional output (supply) and thus increase aggregate income. Laffer curve is used by the supporters of supply side economics to back their claim that low income tax policies spur non-inflationary growth by encouraging new investment.

  3. The Laffer Curve is a theory developed by supply-side economist Arthur Laffer to show the relationship between tax rates and the amount of tax revenue collected by governments. The curve is used to illustrate Laffer’s argument that sometimes cutting tax rates can increase total tax revenue.

  4. The Laffer Curve is based on the economic idea that people will adjust their behavior in the face of the incentives created by income tax rates. Higher income tax rates decrease the incentive to work and invest compared lower rates. If this effect is large enough, it means that at some tax rate, and further increase in the rate will actually lead to decrease in total tax revenue. For every type of tax, there is a threshold rate above which the incentive to produce more diminishes, thereby reducing the amount of revenue the government receives.

How to use Laffer curve in a sentence?

  1. The Laffer Curve describes the relationship between tax rates and total tax revenue, with an optimal tax rate that maximizes total government tax revenue.
  2. The theory of supply side economics and the Laffer curve drove federal marginal tax rates from 91% in 1963 down to 28% when Ronald Reagan left office.
  3. The Laffer Curve was used as a basis for tax cuts in the 1980's with apparent success, but criticized on practical grounds on the basis of its simplistic assumptions, and on economic grounds that increasing government revenue might not always be optimal.
  4. If taxes are too high along the Laffer Curve, then they will discourage the taxed activities, such as work and investment, enough to actually reduce total tax revenue. In this case, cutting tax rates will both stimulate economic incentives and increase tax revenue.
