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.

GOVERNMENT PURCHASES Expenditures made by the government sector on final goods and services, or gross domestic product. Government purchases are used to buy the goods and services needed to operate the government (such as administrative salaries) and to provide public goods (including national defense, highway construction). These purchases are one of two major categories of government spending, the other is transfer payments. Government purchases are financed by a mix of taxes and borrowing and are categorized by the three levels of government: federal, state, and local governments. These are one of four expenditures on gross domestic product. The other three are consumption expenditures, investment expenditures, and net exports.
