AGGREGATE EXPENDITURES: The total expenditures on gross domestic product undertaken in a given time period by the four sectors -- household, business, government, and foreign. Expenditures made by each of these sectors are specifically labeled consumption expenditures, investment expenditures, government purchases, and net exports. Aggregate expenditures (AE) are a cornerstone in the study of macroeconomics, playing critical roles in Keynesian economics, aggregate market analysis, and to a lesser degree, monetarism.

GREEN LOGIGUIN
Your compete MICRO*scope for today
You are the type of person who recognizes that the economy is a perpetual battle between producers and consumers, suppliers and demanders. Family and friends don't understand how you can watch a baseball game and a movie at the same time. Today, you are likely to spend a great deal of time browsing through a long list of dot com websites seeking to buy either a looseleaf notebook binder or hand lotion, a big bottle of hand lotion. Be on the lookout for rusty deck screws. You should consider shopping at stores or businesses beginning with the letter T, but do not buy any products with a serial number or product code containing the number 642473. Your preferred shopping venue is strip malls. Your special symbol is the equal sign (=).
Is this You?
As a Green Logiguin, you seek a balance in life and your market activities. You are logical and reasonable, always seeking to weigh costs and benefits, pros and cons, ups and downs, ins and outs, goods and bads. You are the embodiment of yin and yang. You know that there are two sides to every story and every market exchange. Sometimes you buy. Sometimes you sell. You search out the best deals, with the highest quality and lowest price.
This isn't me! What am I?

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.

A Somewhat Defective Look At PRODUCT SAFETYWAIT! STOP! My shoe's untied! And my blasted shoestring is tangled! Fortunately I have my handy OmniStraight shoestring straightener, a product developed by a team of former NASA scientists that's designed to straighten and untangle even the most convoluted shoestrings. OOPS! You might want to continue your pedestrian journey without me. It seems as though my handy OmniStraight shoestring straightener has inadvertently dissected my shoestring, mangled the upper half of my jogging shoe, and introduced several gashes to the top of my foot. As I faint face-first onto the sidewalk from the loss of blood, you can consider some of the ins and outs of my predicament.
