ARC ELASTICITY: The average elasticity for discrete changes in two variables, A and B. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of the initial and ending values of each variable, rather than only initial values. Arc elasticity is generally calculated using the midpoint formula. Arc elasticity should be compared with point elasticity. For infinitesimally small changes in variables A and B, arc elasticity is the same as point elasticity.

AGGREGATE SUPPLY SHIFTS Changes in the aggregate supply determinants shift both the short-run aggregate supply curve and the long-run aggregate supply curve. The mechanism is comparable to that for market supply determinants and market supply. There are two options--an increase in aggregate supply and a decrease in aggregate supply. An increase in resource quantity or quality or a decrease in resource price shifts one or both of the aggregate supply curves to right. A decrease in resource quantity or quality or an increase in resource price shifts one or both of the aggregate supply curves to left.
