AGGREGATE EXPENDITURE DETERMINANT: A ceteris paribus factor that affects aggregate expenditures, but which is assumed constant when the aggregate expenditure line is constructed. Changes in any of the aggregate expenditures determinants cause the aggregate expenditure line to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate expenditure line to shift, it's usually most convenient to group them into the four, broad expenditure categories -- consumption, investment, government purchases, and net exports. The reason is that changes in these expenditures are the direct cause of shifts in the aggregate expenditure line. If any determinant affects aggregate expenditures it MUST affect one of these four expenditures.

                           IMPORTS LINE: A graphical depiction of the relation between imports bought from the foreign sector and the domestic 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 imports line is characterized by vertical intercept, which indicates autonomous imports, and slope, which is the marginal propensity to import and indicates induced imports. 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 imports line shows the relation between imports purchased from 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 imports line is to graphically illustrate the imports-income relation for the foreign sector, which is then used to derive the net exports line by vertically subtracting it from the exports 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 exports are totally autonomous, imports are induced by the level of domestic income and production. Reflecting this, the imports line is positively-sloped, with the slope equal to the marginal propensity to import (MPM). The vertical intercept, or Y-intercept, of the imports line is then autonomous imports. | Imports Line |  |
The positively-sloped red line, labeled M in the exhibit to the right, indicates a typical imports line. Line any straight line, this imports line is characterized by two key parameters, intercept and slope. The intercept indicates autonomous imports and the slope indicates induced imports.Identifying numbers for these two parameters for this particular line indicates that the intercept is $0, meaning autonomous imports is $0, and the slope is 0.075, meaning a $1 increase in domestic income or production induces a $0.075 increase in imports. In this particular case, the imports line has a zero intercept, indicating no autonomous imports, but that need not be the case. Most notable is that the slope of the imports line is the marginal propensity to import (MPM).
