GOVERNMENT PURCHASES LINE: A graphical depiction of the relation between government purchases and national income (or gross domestic product) that plays a role in Keynesian economics and the Keynesian cross. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity for government purchases. The vertical intercept of this line is autonomous government purchases. The aggregate expenditures line used in the Keynesian cross is obtained by adding this government purchases line, as well as, investment expenditures and net exports, to the consumption line. The government purchases line is also combined with investment expenditures for the Keynesian saving-investment model.

MARGINAL PROPENSITY TO IMPORT The change in imports purchased from the foreign induced by a change in income or production (national income or gross domestic product). The marginal propensity to import (abbreviated MPM) is another term for the slope of the imports line and is calculated as the change in imports divided by the change in income or production. The MPM plays a role in Keynesian economics. It augments the slope of the aggregate expenditures line and is part to 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 at the confiscated property police auction trying to buy either a coffee cup commemorating the 1960 Presidential election or a how-to book on fixing your computer, with illustrations. Be on the lookout for strangers with large satchels of used undergarments.
