SLOPE, SHORT-RUN AGGREGATE SUPPLY CURVE: The short-run aggregate supply (SRAS) curve has a positive slope, reflecting the direct relation between the price level and aggregate real production. A higher price level is related to more real production and a lower price level is related to less real production. The general reason is similar to that of market supply curves--the opportunity cost of production--three specific reasons can be identified: (1) inflexible resource prices that often makes it easier to reduce aggregate real production and resource employment when the price level falls; (2) the pool of natural unemployment, consisting of frictional and structural unemployment, that can be used temporarily to increase aggregate real production when the price level rises; and (3) imbalances in the purchasing power of resource prices that can temporarily entice resource owners to produce more or less aggregate real production than the would at full employment.

INDUCED GOVERNMENT PURCHASES Government purchases that depend on income or production (especially national income and gross domestic product). That is, changes in income induce changes in government purchases. Induced government purchases reflect the observation that the government sector (especially state and local governments) is inclined to use tax revenue, which increases with income, for purchases. They are measured by the marginal propensity for government purchases (MPG) and are reflected by the positive slope of government purchases line. The alternative to induced government purchases is autonomous government purchases, which do not depend on income.
