ASSUMPTIONS, CLASSICAL ECONOMICS: Classical economics, especially as directed toward macroeconomics, relies on three key assumptions--flexible prices, Say's law, and saving-investment equality. Flexible prices ensure that markets adjust to equilibrium and eliminate shortages and surpluses. Say's law states that supply creates its own demand and means that enough income is generated by production to purchase the resulting production. The saving-investment equality ensures that any income leaked from consumption into saving is replaced by an equal amount of investment. Although of questionable realism, these three assumptions imply that the economy would operate at full employment.

Fighting Business Cycles With STABILIZATION POLICIESAs you may recall, the twins, Donna the Democrat and Rhonda the Republican, seldom agree on anything involving politics, economics, fashion, or flower arrangements. Their imminent entry into the Interstate OmniBank can only mean trouble. Donna, in her official capacity as economic advisor to the President of the quaint and courteous Republic of Northwest Queoldiola, is attempting to enter Interstate OmniBank anxious to borrow enough to finance the Queoldiolan government deficit. Rhonda, as the head of the central bank of the Republic of Northwest Queoldiola, is making every effort to stop her. The source of this particular confrontation between the twins is apparently the best way to eliminate a year-long recession that has struck the quaint and courteous Republic of Northwest Queoldiola.
