THE ECONOMIC PROBLEM: Another term for scarcity, which is the 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 (see free lunch). 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.

EXPORTS LINE:

A graphical depiction of the relation between exports sold to the foreign sector and the economy's aggregate level of income or production. This relation is most important for deriving the net exports line, which plays a minor, but growing role in the study of Keynesian economics. An exports line is horizontal which indicates that exports are totally autonomous, with no induced component. The aggregate expenditures line used in Keynesian economics is derived by adding or stacking the net exports line, derived as the difference between the exports line and imports line, onto the consumption line, after adding investment expenditures and government purchases.
The exports line shows the relation between exports of domestic production purchased by the foreign sector and aggregate income or production. The income and production measures most commonly used are national income and gross domestic product. The purpose of the exports line is to graphically illustrate the exports-income relation for the foreign sector, which is then used to derive the net exports line by vertically subtracting the imports line, after which it is then integrated into the aggregate expenditures line used in Keynesian economics.

Net exports are the difference between exports and imports, or exports minus imports. Exports are purchases of domestic production by the foreign sector and imports are purchases of foreign production by the domestic economy. While imports are induced by the level of domestic income and production, exports are totally autonomous. Reflecting this, the exports line is horizontal, with a zero slope. There are no induced exports. The vertical intercept, or Y-intercept, of the exports line reflects autonomous exports.

Exports Line
Exports Line
The horizontal red line, labeled X in the exhibit to the right, indicates a typical exports line. Line any straight line, this exports line is characterized by two key parameters, intercept and slope. The intercept indicates autonomous exports and the slope indicates the degree of induced exports, if any actually existed.

Identifying numbers for these two parameters for this particular line indicates that the intercept is $1 trillion, meaning autonomous exports is $1, and the slope is 0, meaning a $1 increase in domestic income or production induces a $0 decrease in exports. A zero slope means exports are autonomous and equal to $1 trillion for every level of domestic income and production.
