AGGREGATE DEMAND DETERMINANTS: An assortment of ceteris paribus factors that affect aggregate demand, but which are assumed constant when the aggregate demand curve is constructed. Changes in any of the aggregate demand determinants cause the aggregate demand curve to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate demand curve to shift, it's usually most convenient to group them into the four, broad expenditure categories -- consumption, investment, government purchases, and net exports. The reason is that changes in these expenditures are the direct cause of shifts in the aggregate demand curve. If any determinant affects aggregate demand it MUST affect one of these four expenditures.

WHITE GULLIBON
Your compete MICRO*scope for today
You are the type of person who wants only to help others, because that's what helpful people do. Family and friends probably don't even know you exist. Today, you are likely to spend a great deal of time wandering around the shopping mall wanting to buy either a weathervane with a horse on top or a case of blank recordable DVDs. Be on the lookout for the last item on a shelf. You should consider shopping at stores or businesses beginning with the letter F, but do not buy any products with a serial number or product code containing the number 501785. Your preferred shopping venue is television shopping channels. Your special symbol is the minus sign (-).
Is this You?
As a White Gullibon, you are extremely trusting but somewhat impressionable, seeing only the good in other people. You tend to be a bit naive in the wily ways of the marketplace and thus are often exploited by others, especially the Reg Aggressorine. Like it or not, you are the poster child for the phrase "let the buyer beware." You are empathetic to the plight of others, often to your own detriment.
This isn't me! What am I?

INFLEXIBLE PRICES The proposition that some prices adjust slowly in response to market shortages or surpluses. This condition is most important for macroeconomic activity in the short run and short-run aggregate market analysis. In particular, inflexible prices (also termed rigid prices or sticky prices) are a key reason underlying the positive slope of the short-run aggregate supply curve. Prices tend to be the most inflexible in resource markets, especially labor markets, and the least inflexible in financial markets, with product markets falling between the two.

Fact 2: Our Subjective ValuesUpon leaving Scarcity Stan's Bakery Shoppe and Confectionery Palace our pedestrian's excursion drops into Mega-Mart Discount Warehouse Super Center. A quick tour of this mecca of mass production -- lasting no more than three days -- is likely to reveal within the 20 gadzillion square feet of floor space a number of sales racks, shelves, and tables filled with merchandise marked down for clearance. A prominently displayed sign on one sales rack boldly declares that the regular $24.99 price has been drastically reduced, for this week only, to $3.98. What a bargain! What a sale! We have the chance -- "for a limited time only" -- to get stuff valued at $24.99 for only $3.98! With a bargain like this, how can we lose? It's easy to lose, if you don't understand the concept of value. Most of us have several "bargains" stored away in the attic, closet, or garage that never have seen, and probably never will see, anything resembling use. What seemed like a great "bargain" at the store, does nothing but occupy space at home. (By the way, does anyone have use for a distributor cap for a 1949 Ford?)
