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).

CONSUMPTION LINE: A graphical depiction of the relation between household consumption expenditures and household disposable income that forms one of the key building blocks for Keynesian economics. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity to consume. The vertical intercept of the consumption line is autonomous consumption. The aggregate expenditures line used in the Keynesian cross is obtained by adding investment, government purchases, and net exports to the consumption line. Because saving is the difference between disposable income and consumption, the saving line is a complementary relation to the consumption line.

EQUILIBRIUM, SHORT-RUN AGGREGATE MARKET The state of equilibrium that exists in the short-run aggregate market when real aggregate expenditures are equal to full-employment real production with no imbalances to induce changes in the price level or real production. The opposing forces of aggregate demand (the buyers) and short-run aggregate supply (the sellers) exactly offset each other. At the existing price level, the four macroeconomic sectors (household, business, government, and foreign) purchase all of the real production that they seek and producers sell all of the real production that they have.
