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.

SCARCITY: A pervasive condition of human existence that exists because society has unlimited wants and needs, but limited resources used for their satisfaction. In other words, while we all want a bunch of stuff, we can't have everything that we want. In slightly different words, this scarcity problem means: (1) that there's never enough resources to produce everything that everyone would like produced; (2) that some people will have to do without some of the stuff that they want or need; (3) that doing one thing, producing one good, performing one activity, forces society to give up something else; and (4) that the same resources can not be used to produce two different goods at the same time. We live in a big, bad world of scarcity. This big, bad world of scarcity is what the study of economics is all about. That's why we usually subtitle scarcity: THE ECONOMIC PROBLEM. See also | first rule of scarcity | unlimited wants and needs | limited resources | satisfaction | resources | wants | needs | production | consumption | economics | opportunity cost | scarce resource |

MARGINAL PROPENSITY FOR GOVERNMENT PURCHASES The change in government purchases induced by a change in income or production (national income or gross domestic product). The marginal propensity for government purchases (abbreviated MPG) is another term for the slope of the government purchases line and is calculated as the change in government purchases divided by the change in income or production. The MPG plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part of the multiplier process. A related marginal measure is the marginal propensity to consume.

[What's This?]
Today, you are likely to spend a great deal of time flipping through mail order catalogs looking to buy either a pair of red and purple designer socks or a T-shirt commemorating Thor Heyerdahl's Pacific crossing aboard the Kon-Tiki. Be on the lookout for slightly overweight pizza delivery guys.
