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.

SIMPLE EXPENDITURES MULTIPLIER A measure of the change in aggregate production caused by changes in an autonomous expenditure that shocks the macroeconomy, when consumption is the ONLY induced expenditure. The simple expenditures multiplier is the inverse of one minus the marginal propensity to consume, or more simply the inverse of the marginal propensity to save. A related multiplier is the simple tax multiplier, which measures the change in aggregate production caused by changes in taxes.
