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).

GROSS PRIVATE DOMESTIC INVESTMENT

This is the official item in the National Income and Product Accounts maintained by the Bureau of Economics Analysis measuring capital investment expenditures. Gross private domestic investment is expenditures on capital goods to be used for productive activities in the domestic economy that are undertaken by the business sector during a given time period. These expenditures tend to be the least stable of the four expenditures, averaging between 12-18 percent of gross domestic product. This percentage tends to be at the low end during business-cycle contractions and at the high end during business-cycle expansions. The other official expenditures included in the National Income and Product Accounts are personal consumption expenditures, government consumption expenditures and gross investment, and net exports of goods and services.
