AE LINE: Another term for aggregate expenditure line, which is 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.

OLIGOPSONY A market characterized by a small number of large buyers controlling the buying-side of a market. Oligopsony is the buying-side equivalent of a selling-side oligopoly. Much as a oligopoly is a market dominated by a few large sellers, oligopsony is a market dominated by a few large buyers. While oligopsony could be analyzed for any type of market it tends to be most relevant for factor markets in which a handful of firms control the buying of a factor. Two related buying side market structures are monopsony and monopsonistic competition.

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.
