A: The common notation for the "intercept" term of an equation specified as Y = a + bX. Mathematically, the a-intercept term indicates the value of the Y variable when the value of the X variable is equal to zero. Theoretically, the a-intercept is frequently used to indicate exogenous or independent influences on the Y variable, that is, influences that are independent of the X variable. For example, if Y represents consumption and X represents national income, a measures autonomous consumption expenditures.

SPATIAL DIFFERENTIATION: The notion that economic activity is not evenly dispersed across the land. That is, goods, services, resources, production, and consumption are more concentrated at some locations and less concentrated at other locations due to natural endowments and human activity. The result is that no two location points have exactly the same access to inputs or outputs. This is a fundamental principle underlying the study of urban and regional economics and implies that firms and households must include transportation cost and location in production and consumption decisions.

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.
