I: The standard abbreviation for investment expenditures by the business sector, especially when used in the study of macroeconomics. This abbreviation is most often seen in the aggregate expenditure equation, AE = C + I + G + (X - M), where C, G, and (X - M) represent expenditures by the other three macroeconomic sectors, household, business, and foreign.

PURPLE SMARPHIN
Your compete MICRO*scope for today
You are the type of person who thinks of shopping as a necessity, but not the most important thing that you will do today. Family and friends treat you as a walking encyclopedia, which is okay with you. Today, you are likely to spend a great deal of time flipping through the yellow pages trying to buy either a remote controlled World War I bi-plane or a wall poster commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for malfunctioning pocket calculators. You should consider shopping at stores or businesses beginning with the letter J, but do not buy any products with a serial number or product code containing the number 589009. 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?

ASSUMPTIONS, KEYNESIAN ECONOMICS The macroeconomic study of Keynesian economics relies on three key assumptions--rigid prices, effective demand, and savings-investment determinants. First, rigid or inflexible prices prevent some markets from achieving equilibrium in the short run. Second, effective demand means that consumption expenditures are based on actual income, not full employment or equilibrium income. Lastly, important savings and investment determinants include income, expectations, and other influences beyond the interest rate. These three assumptions imply that the economy can achieve a short-run equilibrium at less than full-employment production.

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.
