MARKET SHOCK: A disruption of market equilibrium (that is, a market adjustment) caused by a change in a demand determinant (and a shift of the demand curve) or a change in a supply determinant (and a shift of the supply curve). A market shock can take one of four forms--an demand increase, demand decrease, supply increase, or supply decrease. An increase is seen as a rightward shift of either curve and results in an increase in equilibrium quantity. A decrease is a leftward shift of either curve and results in a decrease in equilibrium quantity. However, a change in demand results in price and quantity to change in the same direction, while a change in supply causes equilibrium price to move the opposite direction as quantity.

PURPLE SMARPHIN
Your compete MICRO*scope for today
You are the type of person who knows that you are highly intelligent, but has no reason to flaunt it. Family and friends get irritated when you explain, for the umpteenth time, the difference between a partial derivative and a total derivative. Today, you are likely to spend a great deal of time visiting every yard sale in a 30-mile radius seeking to buy either a wall poster commemorating last Friday (you know why) or a country wreathe. Be on the lookout for small children selling products door-to-door. You should consider shopping at stores or businesses beginning with the letter C, but do not buy any products with a serial number or product code containing the number 663939. Your preferred shopping venue is the Internet. Your special symbol is the exclamation point (!).
Is this You?
As a Purple Smarphin, you are the brightest and most intelligent person you know. And that goes for shopping, too. You know exactly what you want. You know exactly what it costs. You know exactly when and where to buy. But, of course, shopping is only one of the many activities that attracts your intellectual attention. You shop when you need to and buy if have to, but shopping is not the end all of your life.
This isn't me! What am I?

Charging Up Your CREDIT CARDS (aka Plastic Money)Here's the scene: You've made your monthly stop (for the second time this week) at the Mega-Mart Discount Warehouse Super Center for a few essentials -- cashews, soap, licorice, garden hose, peanut clusters, color television, and a large inner tube for whitewater rafting. Do you pay with a check or whip out your Interstate OmniBank Platinum Diamond Express credit card? Credit card? Good choice. You don't actually have to PAY for the stuff that you're buying -- at least not right away. Your bank account is safe.
