AGGREGATE EXPENDITURE LINE: A line representing the relation between aggregate expenditures and gross domestic product used in the Keynesian cross. The aggregate expenditure line is obtained by adding investment expenditures, government purchases, and net exports to the consumption line. As such, the slope of the aggregate expenditure line is largely based on the slope of the consumption line (which is the marginal propensity to consume), with adjustments coming from the marginal propensity to invest, the marginal propensity for government purchases, and the marginal propensity to import. The intersection of the aggregate expenditures line and the 45-degree line identifies the equilibrium level of output in the Keynesian cross.

BROWN PRAGMATOX
Your compete MICRO*scope for today
You are the type of person who could have been the inspiration for the phrase "salt of the earth". Family and friends look to you as a pillar of strength, and rightly so. Today, you are likely to spend a great deal of time at the confiscated property police auction looking to buy either a how-to book on the art of negotiation or a flower arrangement for your aunt. Be on the lookout for door-to-door salesmen. You should consider shopping at stores or businesses beginning with the letter B, but do not buy any products with a serial number or product code containing the number 456850. 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?

PERFECT COMPETITION, LONG-RUN ADJUSTMENT A perfectly competitive industry undertakes a two-part adjustment to equilibrium in the long run. One is the adjustment of each perfectly competitive firm to the appropriate factory size that maximizes long-run profit. The other is the entry of firms into the industry or exit of firms out of the industry, to eliminate economic profit or economic loss. The end result of this long-run adjustment is a multi-faceted equilibrium condition that price is equal to marginal cost and average cost (both short run and long run).

Pumping Up The ECONOMIC GROWTHWe need to pay another visit to Scarcity Stan's Ye Olde Bakery Shoppe and Confectionery Palace. But this is not a social visit, nor is intended for some delectable pastries that will add a few extra pounds to our waistlines. We're here on official economic business. Stan's at wits end. He doesn't know what to do. There's been so much demand for his economic pie, what with society's unlimited wants and needs, that he needs to make it bigger. Our job is to figure out how. While we're doing that, we'll also see how to put our economy on the path to economic growth.
