DISEQUILIBRIUM, AGGREGATE MARKET: The state of the aggregate market in which real aggregate expenditures are NOT equal to real production, which result in imbalances that induce changes in the price level, aggregate expenditures, and/or real production. In other words, the opposing forces of aggregate demand (the buyers) and aggregate supply (the sellers) are out of balance. Either the four macroeconomic sector (households, business, government, and foreign) buyers are unable to purchase all of the real production that they seek at the existing price level or business-sector producers are unable to sell all of the real production that they have available at the existing price level.

ADVERSE SELECTION An inefficient, bad, or adverse outcome of a market exchange that results because buyers and/or sellers make decisions based on asymmetric information. This commonly results in a market that exchanges a lesser quality good, what is termed the market for lemons. Two related problems resulting from asymmetric information are moral hazard and the principal-agent problem. Two methods of lessoning the problem of adverse selection are signalling and screening.

Fact 3: Our Unfair LivesAcross the interstate from the Mega-Mart Discount Warehouse Super Center resides the Shady Valley Central Town Sprawling Hills Shopping Mall -- a prime example of our economy's climate-controlled, suburban shopping phenomenon. Our pedestrian's ramble through the economy would be totally inadequate if we did not spend at least one day strolling past the endless rows of stores with their displays of clothes, shoes, electronics, clothes, luggage, clothes, cheese pretzels, and of course clothes. Our pedestrian trip, however, is not concerned with the products exhibited beyond the stylish glass windows. No, our jumping off point is the gadzillions of people who pass us by, bump into us, get in our way, and generally make our shopping experience comparable to a commuter train during the rush hour. Those who comprise the shopping crowd are short, tall, young, old, fat, thin, black, white, happy, and sad. More importantly for our present discussion, however, is that some are rich and some are not-so-rich. A few of the wealthier shoppers actually buy the products framed by the picturesque windows that line the air-conditioned quaint mid-way of Shady Valley Central Town Sprawling Hills Shopping Mall. Others must be content to ogle the prominently displayed products or perhaps buy an occasional cheese pretzel.
