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.

AVERAGE FACTOR COST AND MARGINAL FACTOR COST

A mathematical connection between average factor cost and marginal factor cost stating that the change in the average factor cost depends on a comparison between average factor cost and marginal factor cost. For perfect competition, with no market control, marginal factor cost is equal to average factor cost, and average factor cost does not change. For monopsony and other firms with market control, marginal factor cost is greater than average factor cost, and average factor cost rises.

Gambling On A State LOTTERY

You might recall during our discussion of gambling in the entry appropriately titled gambling, that I purchased $5 worth of Super Luck-O Multi-State Lottery tickets at the Master's Sprocket convenience store. Well, the day of the big drawing came and went. I was about as close to winning as the planet Pluto is to buying a Hot Mamma Fudge Bananarama Ice Cream Sundae on a cold winter morning. At least the five dollars I paid for lottery tickets goes to a good cause. The state uses a share of the proceeds for education, and that keeps my taxes lower. If you'll excuse me for a moment, I've got another ten bucks in my pocket screaming for the chance to by some more Super Luck-O Multi-State Lottery tickets. While I'm doing that, why don't you see if this is a wise consumption move on my part.
