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).

CONSUMER PRICE INDEX

An index of prices of goods and services typically purchased by urban consumers. The Consumer Price Index (CPI) is compiled and published monthly by the Bureau of Labor Statistics (BLS), using price data obtained from an elaborate survey of 25,000 retail outlets and quantity data generated by the Consumer Expenditures Survey. The CPI is one of two key price indexes used as a measure of the price level and to estimate the inflation rate. The other is the GDP price deflator. The CPI is also officially designated as the Consumer Price Index for All Urban Consumers (CPI-U). Another noted price index is the Producer Price Index (PPI).
