AE LINE: Another term for aggregate expenditure line, which is 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.

BLACK DISMALAPOD
Your compete MICRO*scope for today
You are the type of person who expects only the worst from others and are never disappointed. Family and friends keep forgetting your birthday and losing your telephone number. Today, you are likely to spend a great deal of time looking for a downtown retail store looking to buy either a black duffle bag with velcro closures or any book written by Isaac Asimov. Be on the lookout for strangers with large satchels of used undergarments. You should consider shopping at stores or businesses beginning with the letter J, but do not buy any products with a serial number or product code containing the number 740351. Your preferred shopping venue is convenience stores. Your special symbol is the pound sign (#).
Is this You?
As a Black Dismalapod, you tend to be grumpy and gloomy, morose and melancholy, and often downcast and disgruntled. You don't really trust others and expect only the worst from them. You are seldom disappointed. You tend to spend a lot of time by yourself. Sadly, you recognize that you are destined to come up on the short end of any economic transaction.
This isn't me! What am I?

PERFECT COMPETITION, EFFICIENCY Perfect competition is an idealized market structure that achieves an efficient allocation of resources. This efficiency is achieved because the profit-maximizing quantity of output produced by a perfectly competitive firm results in the equality between price and marginal cost. In the short run, this involves the equality between price and short-run marginal cost. In the long run, this is seen with the equality between price and long-run marginal cost at the minimum efficient scale of production.

My Sales Pitch On ADVERTISINGOur extended sojourn through the winding complexities of the economy has worn the soles from my jogging shoes. For the best bargain on a new pair, let's consult those annoying flyers stuffed into the Sunday newspaper. We're in luck. The Mega-Mart Discount Warehouse Super Center is having their monthly "once in a lifetime" sale on jogging shoes. Without this Mega-Mart Discount Warehouse Super Center advertising supplement, I might have unknowingly paid a higher price for my brand new Fleet Feet Footwear jogging shoes. Isn't advertising wonderful?
