MC: The abbreviation for marginal cost, which is the change in total cost (or total variable cost) resulting from a change in the quantity of output produced by a firm in the short run. Marginal cost indicates how much total cost changes for a give change in the quantity of output. Because changes in total cost are matched by changes in total variable cost in the short run (remember total fixed cost is fixed), marginal cost is the change in either total cost or total variable cost. Marginal cost is found by dividing the change in total cost (or total variable cost) by the change in output.

SAVING-INVESTMENT MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.

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.

PINK FADFLY
[What's This?]
Today, you are likely to spend a great deal of time looking for the new strip mall out on the highway seeking to buy either a T-shirt commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki or a wall poster commemorating the 2000 Olympics. Be on the lookout for bottles of barbeque sauce that act TOO innocent.
