AGGREGATE EXPENDITURES 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.

DEMAND AND SUPPLY INCREASE A simultaneous increase in the willingness and ability of buyers to purchase a good at the existing price, illustrated by a rightward shift of the demand curve, and an increase in the willingness and ability of sellers to sell a good at the existing price, illustrated by a rightward shift of the supply curve. When combined, both shifts result in an increase in equilibrium quantity and an indeterminant change in equilibrium price.

Fact 4: Our Monopolized MarketsOur pedestrian's jaunt through the economy is not, unfortunately, an unrestrained shopping spree for confectioneries, spark plug tools, and Houston, Texas. We have other important errands to run. At the moment we need to hike over to Shady Valley's exclusive provider of cable television services, the Merciless Monolithic Media Masters Cable Television Company, Inc., to inquire about a mysterious fee that appeared last month's bill. The good news is that the Merciless Monolithic Media Masters (the 4M people) Cable office is a mere 2 miles (3 kilometers for the metrically inclined) from the Shady Valley Central Town Sprawling Hills Shopping Mall. A hop, skip, and a moderately long jump later, our excursion through the economy takes us to the front door of the 4M Cable Television Company where I hope to discover why last month's cable bill included a $3,569 charge for something called "The Vacation Channel." I didn't even know I had a vacation channel. (But, I'm sure it's a great channel, and if I don't have it, then I will certainly subscribe. Please don't disconnect me.) Of course, because this an afternoon workday, the doors of the 4M office are locked. I can almost make out, through the expensive stained glass windows, what appears to be several Merciless Monolithic Media Masters Cable Television employees, with champaign bottles in hand, dancing on expensive mahogany desks. Let's not disturb them. As they say in the cable business, an upset worker is a disconnected customer.
