LAFFER CURVE: The graphical inverted-U relation between tax rates and total tax collections by government. Developed by economist Arthur Laffer, the Laffer curve formed a key theoretical foundation for supply-side economics of President Reagan during the 1980s. It is based on the notion that government collects zero revenue if the tax rate is 0% and if the tax rate is 100%. At a 100% tax rate no one has the incentive to work, produce, and earn income, so there is no income to tax. As such, the optimum tax rate, in which government revenue is maximized, lies somewhere between 0% and 100%. This generates a curve shaped like and inverted U, rising from zero to a peak, then falling back to zero. If the economy is operating to the right of the peak, then government revenue can be increased by decreasing the tax rate. This was used to justify supply-side economic policies during the Reagan Administration, especially the Economic Recovery Tax Act of 1981 (Kemp-Roth Act).

DERIVATION, SAVING LINE A saving line, a graphical depiction of the relation between household sector saving and income, can be derived from the consumption line. The saving line can also be derived by plotting the saving-income information from a saving schedule or using the slope and intercept values of the saving function. However, derivation from the consumption line emphasis the connection between consumption and income--that the household sector uses a portion of income for consumption and a portion for saving.
