the theory that investment incentives such as lowered federal spending and tax cuts will stimulate economic growth and increased employment.
The Laffer Curve
Shows the relationship between the tax rates and tax revenue collected by governments; as tax rates increase from low levels, tax revenue would increase; if taxes rise too high people stop working; lack of work leads to a lack in income and therefore, a fall in tax revenue

rational expectations theory
A branch of New Classical theory which holds that firms and individuals have rational expectations about the economy and government policies and thus may pursue their own interests in such a way as to render those policies ineffective.
Economists who believe that (1) monetary instability is the major cause of fluctuations in real GDP and (2) rapid growth of the money supply is the major cause of inflation.
speed of adjustment
Amount of time that it takes prices to fully adjust so that all markets are in equilibrium and output equals potential output.
efficiency wage theory
an explanation for unemployment that says employees who are paid above the market wage rate have incentive to be more productive, giving employers an incentive to pay them above market wage
