AGGREGATE DEMAND DETERMINANT: A ceteris paribus factor that affects aggregate demand, but which is assumed constant when the aggregate demand curve is constructed. Changes in any of the aggregate demand determinants cause the aggregate demand curve to shift. While a wide variety of specific ceteris paribus factors can cause the aggregate demand curve 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 demand curve. If any determinant affects aggregate demand it MUST affect one of these four expenditures.

MARGINAL PROPENSITY TO INVEST The change in business investment expenditures induced by a change in income or production (national income or gross domestic product). The marginal propensity to invest (abbreviated MPI) is another term for the slope of the investment line and is calculated as the change in investment divided by the change in income or production. The MPI 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.
