ELASTICITY AND DEMAND SLOPE: The slope of a straight-line demand curve, one with a constant slope, has constantly change elasticity. No two points on a straight-line demand curve as the same elasticity. The point of intersection between the demand curve and the vertical, price axis is perfectly elastic (E = ∞). The intersection point between the demand curve and the horizontal, quantity axis is perfectly inelastic (E = 0). The exact middle, or midpoint, of the demand curve is unit elastic (E = 1). The segment between the midpoint and the price-axis intercept is relatively elastic (1 < E < ∞). The segment between the midpoint and the quantitY-axis intercept is relatively inelastic (0 < E < 1).

AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the four macroeconomic sectors (household, business, government, and foreign) and the level of aggregate income or production. In Keynesian economics, the aggregate expenditures line is the essential component of the Keynesian cross analysis used to identify equilibrium income and production. Like any straight line, the aggregate expenditures line is characterized by vertical intercept, which indicates autonomous expenditures, and slope, which indicates induced expenditures. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking investment, government purchases, and net exports to the consumption line.
