KEYNESIAN EQUILIBRIUM: The state of the macroeconomy in which aggregate expenditures are equal to aggregate output. This is illustrated using the income-expenditure model, or Keynesian cross, as the intersection of the aggregate expenditures line and the 45-degree line. The aggregate expenditures line is the summation of consumption expenditures, investment expenditures, government purchases, and net exports. The 45-degree line represents all combinations in which aggregate expenditures equal aggregate output. Keynesian equilibrium is also represented by the saving-investment, or injection-leakage, model as the intersection between the injection line (investment expenditures, government purchases, and exports) and the leakage line (saving, taxes, and imports).

YELLOW CHIPPEROON
Your compete MICRO*scope for today
You are the type of person who thinks about shopping from the time you wake up in the morning until the time you go to sleep at night. Family and friends never know what to give you as a present, because you've already bought it. Today, you are likely to spend a great deal of time browsing about a thrift store hoping to buy either a genuine down-filled comforter or a 200-foot blue garden hose. Be on the lookout for deranged pelicans. You should consider shopping at stores or businesses beginning with the letter K, but do not buy any products with a serial number or product code containing the number 281846. Your preferred shopping venue is shopping malls. Your special symbol is the asterisk (*).
Is this You?
As a Yellow Chipperoon, you are happy, happy, happy. You enjoy everything about life and about shopping. You love shopping. You love buying. You love spending. You love to compare products and prices. You love the crowds. You love chatting with the store clerks. You love every bit of the buying process. Nothing dissuades you from having a good time shopping, whether you're buying a box of facial tissues or a new house. Does it get any better than spending an afternoon at the shopping mall? No way!
This isn't me! What am I?

DETERMINANT This has one of two somewhat related meanings. First, it refers to a ceteris paribus factor that is held constant when a curve or graphical relation between two other variables is constructed. Second, it refers to a known directional change in a variable resulting from the disruption of an equilibrium that is identified using comparative statics.

Fact 1: Our Limited PieThe first stop for any pedestrian on a leisurely stroll through the busy economic streets of Shady Valley is Scarcity Stan's Ye Olde Bakery Shoppe and Confectionery Palace. The most noted pastry on Scarcity Stan's list of delectables, wedged between his mouth-watering apple danishes and scrumptious jelly donuts, is economic pie. My mouth waters with the thought. Economic pie isn't like other donuts, cakes, and confectioneries with their gobs of sweetness, but very little nutritional sustenance. In fact, given that it refers to the sum total of the economy's resources and productive activity, economic pie is filled to the brim with sustenance. Unfortunately, Scarcity Stan and the congregation of people we call society, has only one economic pie, and while it's pretty large, it's never quite as big as we would like.
