AGGREGATE EXPENDITURES LINE: A line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

MARGINAL PROPENSITY TO CONSUME The proportion of each additional dollar of household income that is used for consumption expenditures. The marginal propensity to consume (abbreviated MPC) is another term for the slope of the consumption line and is calculated as the change in consumption divided by the change in income. The MPC plays a central role in Keynesian economics. It quantifies the consumption-income relation and the fundamental psychological law. It is also a foundation for the slope of the aggregate expenditures line and is critical to the multiplier process. A related consumption measure is the average propensity to consume.

What Do You Have Against DISCRIMINATION?Hunger is, of course, an avoidable malady when ambling through the economy. At the present, I'm easily tempted by a hamburger, fries, and large cola -- a pedestrian meal if there ever was one. As luck would have it, we've found ourselves at the door of Big Ott's Boiled Burger Buffet. Luck, though, is not totally on our side. Big Ott's has a large sign prominently posted at the entry to his establishment. It screams in no uncertain terms: NO PEDESTRIANS ALLOWED. As a well-known, card-carrying pedestrian, I am, to say the least, taken aback. Why on earth would Big Ott's Boiled Burger Buffet refuse service to pedestrians? A quick quiz of an employee reveals that Big Ott once swerved off the sidewalk to avoid striking a pedestrian, causing extensive damage to his sleek, new OmniMotors XL GT 9000 convertible sport coupe. His anger has been since extended to all who travel by foot.
