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.

GOVERNMENT PURCHASES LINE A graphical depiction of the relation between government purchases by the government sector and the economy's aggregate level of income or production. This relation plays a key role in the study of Keynesian economics. A government purchases line is characterized by vertical intercept, which indicates autonomous government purchases, and slope, which is the marginal propensity for government purchases and indicates induced government purchases. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the government purchases line onto the consumption line, as well as investment expenditures and net exports.
