GOVERNMENT PURCHASES LINE: A graphical depiction of the relation between government purchases and national income (or gross domestic product) that plays a role in Keynesian economics and the Keynesian cross. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity for government purchases. The vertical intercept of this line is autonomous government purchases. The aggregate expenditures line used in the Keynesian cross is obtained by adding this government purchases line, as well as, investment expenditures and net exports, to the consumption line. The government purchases line is also combined with investment expenditures for the Keynesian saving-investment model.

BROWN PRAGMATOX
Your compete MICRO*scope for today
You are the type of person who is hardworking and industrious, who knows your job and what needs to be done. Family and friends wonder how you can be so happy given what you have. Today, you are likely to spend a great deal of time watching infomercials trying to buy either a cross-cut paper shredder or a birthday greeting card for your father. Be on the lookout for a thesaurus filled with typos. You should consider shopping at stores or businesses beginning with the letter A, but do not buy any products with a serial number or product code containing the number 909738. 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.

Borrowing Through The FINANCIAL MARKETSWe never know whom we might encounter on our leisurely stroll through the economy. Passing by the marble columns of Interstate OmniBank -- the beacon of safety and security -- we have the good fortune of crossing paths with our Ivy-League-educated pillar of the financial community -- Winston Smythe Kennsington III. Although he seems to be a touch condescending, he's kind enough to show us a freshly signed check for $37 gadzillion, which is but a small part of a multi-gadzillion dollar loan from the Interstate OmniBank. To what constructive purpose Winnie will put these funds remains unclear; how this loan will be repaid, he never says; but Winnie proudly reminds us several times that this loan once again proves his unchallenged standing as the majordomo of the financial markets.
