AD CURVE: The aggregate demand curve, which is a graphical representation of the relation between aggregate expenditures on real production and the price level, holding all ceteris paribus aggregate demand determinants constant. The aggregate demand, or AD, curve is one side of the graphical presentation of the aggregate market. The other side is occupied by the aggregate supply curve (which is actually two curves, the long-run aggregate supply curve and the short-run aggregate supply curve). The negative slope of the aggregate demand curve captures the inverse relation between aggregate expenditures on real production and the price level. This negative slope is attributable to the interest-rate effect, real-balance effect, and net-export effect.

BROWN PRAGMATOX
Your compete MICRO*scope for today
You are the type of person who is hardworking and industrious, who knows your job and what needs to be done. Family and friends never, never, never try to convince you of an alternative point of view, political or otherwise. Today, you are likely to spend a great deal of time browsing through a long list of dot com websites wanting to buy either a birthday greeting card for your aunt or a wall poster commemorating the moon landing. Be on the lookout for deranged pelicans. You should consider shopping at stores or businesses beginning with the letter B, but do not buy any products with a serial number or product code containing the number 414160. Your preferred shopping venue is thrift stores. Your special symbol is the comma (,).
Is this You?
As a Brown Pragmatox, you are down-to-earth and practical. You are hard working and industrious. You are frugal to the point that you might even refrain from making a purchase that you really, really need. Doing so often causes problems down the road. You definitely go with function over form and substance over style.
This isn't me! What am I?

MARGINAL REVENUE CURVE, PERFECT COMPETITION A curve that graphically represents the relation between the marginal revenue received by a perfectly competitive firm for selling its output and the quantity of output sold. Because a perfectly competitive firm is a price taker and faces a horizontal demand curve, its marginal revenue curve is also horizontal and coincides with its average revenue (and demand) curve. A perfectly competitive firm maximizes profit by producing the quantity of output found at the intersection of the marginal revenue curve and marginal cost curve.

Planning On SOCIAL SECURITY?This may be the greatest day of my life. The musical group to top all musical groups -- The Strollers -- has just released its latest CD with a song that's certain to be a foot-tapping classical. Of course, you know the song of which I speak -- "Sidewalking." Let's stop into the Musical Sound CD Emporium in the Shady Valley Central Town Sprawling Hills Shopping Mall and fulfill my dreams. Everyone in Shady Valley, however, does not share my joy. As the seventeen year old Emporium clerk, Alicia Hyfield, completes my transaction, she confesses more than a bit of disgruntlement over here just-issued paycheck. A little investigation reveals some displeasure with the size of the FICA deduction. Her disgruntlement isn't lessened to know that this is for the government's social security program that's suppose to provide a source of income in her golden years. She seems more than a bit skeptical of ever seeing any returns. Maybe we can alleviate her concerns (and mine) with a quick run through social security.
