AGGREGATE EXPENDITURE EQUATION: An equation indicating that aggregate expenditures (AE) are the sum of consumption expenditures (C), investment expenditures (I), government purchases (G), and net exports (X-M), stated as: AE = C + I + G + (X-M). This equation surfaces in the Keynesian economic income-expenditure model in the form of the aggregate expenditures line. However, it's also central throughout the study of macroeconomics, including aggregate demand and the measurement of gross domestic product.

BROWN PRAGMATOX
Your compete MICRO*scope for today
You are the type of person who tends to be head-strong and committed to a task. Family and friends never, never, never ask you for a loan. Today, you are likely to spend a great deal of time flipping through the yellow pages seeking to buy either a flower arrangement with daisies and carnations for your uncle or a coffee cup commemorating next Thursday. Be on the lookout for attractive cable television service repair people. You should consider shopping at stores or businesses beginning with the letter Y, but do not buy any products with a serial number or product code containing the number 047909. Your preferred shopping venue is thrift stores. Your special symbol is the comma (,).
Is this You?
As a Brown Pragmatox, you are down-to-earth and practical. You are hard working and industrious. You are frugal to the point that you might even refrain from making a purchase that you really, really need. Doing so often causes problems down the road. You definitely go with function over form and substance over style.
This isn't me! What am I?

SLOPE, AGGREGATE EXPENDITURES LINE The positive slope of the aggregate expenditures line is the sum of the marginal propensity to consume (MPC), marginal propensity to invest (MPI), and marginal propensity for government purchases (MPG), less the marginal propensity to import (MPM). This slope is greater than zero but less than one, reflecting induced expenditures by the four macroeconomic sectors (household, business, government, and foreign). The slope of the aggregate expenditures line determines the magnitude of the multiplier process.

Taming Our Beastly FEDERAL DEFICITIt's almost impossible to take a leisurely stroll around the economy without crashing headlong into the federal deficit. It doesn't take a microscope to see it bulging from the windows and doors of the Sylvester J. Peabody Federal Office Building as we pass by. It's a monstrous beast that seems to be growing by the minute. But is the federal deficit really as ghoulish and gruesome as drawn by political cartoonists? Should we make a detour of our pedestrian trek to avoid the beast? Considering it's size, is avoidance even possible. To answer these question, let's consider the pluses and minuses of our federal deficit.
