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.

TWO-SECTOR AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the two private sectors (household and business) and the level of aggregate income or production. The two-sector aggregate expenditures line combines consumption expenditures and investment expenditures. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for the marginal propensity to invest if it is assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the three-sector aggregate expenditures line and the four-sector aggregate expenditures line.
