A: The common notation for the "intercept" term of an equation specified as Y = a + bX. Mathematically, the a-intercept term indicates the value of the Y variable when the value of the X variable is equal to zero. Theoretically, the a-intercept is frequently used to indicate exogenous or independent influences on the Y variable, that is, influences that are independent of the X variable. For example, if Y represents consumption and X represents national income, a measures autonomous consumption expenditures.

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.
