CHANGE IN AGGREGATE SUPPLY: A shift of the short-run or long-run aggregate supply curve caused by a change in one of the aggregate supply determinants. In essence, a change in aggregate supply is caused by any factor affecting supply EXCEPT the price level. This concept should be contrasted directly with a change in real production. You might also want to review the terms change in quantity supplied and change in supply, as well. The change in aggregate supply is comparable to the change in market supply. A change in aggregate supply is a change in ALL price level-real production combinations, meaning that each price level is matched up with a different level of real production (which is then illustrated as a shift of the short-run or long-run aggregate supply curve). This change in aggregate supply is caused by a change in any of the aggregate supply determinants. In contrast, a change in real production is a change from one price level-real production combination to the another.

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.
