SAVING FUNCTION: The positive relation between household saving and household disposable income. The saving function is commonly presented as the saving line or propensity-to-saving line. The slope of this line is the marginal propensity to save, which is the proportion of any additional income used for saving. The saving function and the marginal propensity to saving play key roles in the multiplier and accelerator concepts. Because consumption is the difference between disposable income and saving, the consumption function is a complementary relation to the saving function.

PURPLE SMARPHIN
Your compete MICRO*scope for today
You are the type of person who has an exceedingly organized mind, but a somewhat cluttered life. Family and friends refuse to let you watch "Jeopardy" with them. Today, you are likely to spend a great deal of time flipping through the yellow pages trying to buy either a velvet painting of Elvis Presley or a wall poster commemorating yesterday. Be on the lookout for vindictive digital clocks with revenge on their minds. You should consider shopping at stores or businesses beginning with the letter W, but do not buy any products with a serial number or product code containing the number 082567. 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?

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.
