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).

INTEREST RATES, AGGREGATE DEMAND DETERMINANT One of several specific aggregate demand determinants assumed constant when the aggregate demand curve is constructed, and that shifts the aggregate demand curve when it changes. An increase in interest rates cause a decrease (leftward shift) of the aggregate curve. A decrease in interest rates an increase (rightward shift) of the aggregate curve. Other notable aggregate demand determinants include the federal deficit, inflationary expectations, and the money supply.

[What's This?]
Today, you are likely to spend a great deal of time watching the shopping channel looking to buy either a T-shirt commemorating the second moon landing or a coffee cup commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for bottles of barbeque sauce that act TOO innocent.
