ABSTRACTION METHODS: Abstraction is the process of simplifying the complexities of the real world by ignoring (hopefully) unimportant details, especially (for our purposes) while doing economic analysis. Three common methods of actual, real world abstraction used in economic theories are words, graphs, and equations. Words can be misunderstood. Graphs are a little more precise. And equations tend to be the most precise of the three.

GRAY SKITTERY
Your compete MICRO*scope for today
You are the type of person who could head off to the food market to buy a loaf of bread and end up parked in front of a plumbing supply warehouse not know how you got there or why. Family and friends seem to be so sure of themselves, so confident, so able to make decisions, it just makes you sick. Today, you are likely to spend a great deal of time searching for a specialty store hoping to buy either a birthday greeting card for your aunt or a wall poster commemorating the moon landing. Be on the lookout for jovial bank tellers. You should consider shopping at stores or businesses beginning with the letter Z, but do not buy any products with a serial number or product code containing the number 194931. Your preferred shopping venue is mail order catalogs. Your special symbol is the question mark (?).
Is this You?
As a Gray Skittery, you are ambivalent, indecisive, and uncertain. You are in a constant struggle between the forces of demand and supply, production and consumption, good and evil... and you're losing the battle. You have trouble making decisions and choosing from among the seemingly infinite number of options that you perpetually face. Your shopping experiences are inevitably confusing.
This isn't me! What am I?

TWO-SECTOR AGGREGATE EXPENDITURES LINE A graphical depiction of the relation between aggregate expenditures by the two private sectors (household and business) and the level of aggregate income or production. The two-sector aggregate expenditures line combines consumption expenditures and investment expenditures. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for the marginal propensity to invest if it is assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the three-sector aggregate expenditures line and the four-sector aggregate expenditures line.

An Altogether Look at UNIONSHey, look! Is that who I think it is? Yes of course, that's Dan Dreiling the drywall guy. You might recall that Dan repaired a hole in my living room wall back in Fact 7. He's coming out of the Mona Mallard Duct Tape Industries plant with all of the duct tape factory workers. And he seems most distressed. Let's get to the bottom of this. Here's his story. The drywall business sort of dried up, and Dan has taken up employment in the exciting field of duct tape fabrication. The duct tape workers, though, are talking union. Dan's indecisive about this move toward unionization. Perhaps we can help him out. Let's stroll around the often controversial topic of labor unions.
