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.

ELASTIC The general relation between two variables in which relatively small changes in one variable (A) cause relatively large changes in another variable (B). Small changes in variable A cause relatively large changes in variable B or the percentage change in variable B is larger than the percentage change in variable A. This characterization of elasticity is most important for the price elasticity of demand and the price elasticity of supply. Elastic is one of two general elasticity relations between two variables. The other is inelastic.
