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).

GOVERNMENT CONSUMPTION EXPENDITURES AND GROSS INVESTMENT The official item in the National Income and Product Accounts maintained by the Bureau of Economics Analysis measuring government purchases undertaken by the government sector. Government consumption expenditures and gross investment averages between 15-20 percent of gross domestic product. As might be expected, this percentage tends to be ebb and flow with the political winds. Some political leaders prefer more government activity, others less. However, this percentage is even more dependent on military conflicts and wars that require massive government activity. The other official expenditures included in the National Income and Product Accounts are personal consumption expenditures, gross private domestic investment, and net exports of goods and services.
