BENEFIT-COST RATIO: The benefit of an activity per dollar of cost. Benefit-cost ratios (or alternatively cost-benefit ratios) are frequently estimated for many forms of government spending, as well as a growing number of business investments. This technique was originally developed to determine if public investment projects, like dams, public parks, highways, etc., were worth doing. The logic is simple -- If benefits are greater than costs, then the project is worthwhile, if they are less, then it isn't.

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).
