ENDPOINT FORMULA: A simple technique for calculating the coefficient of elasticity that estimates the elasticity for discrete changes in two variables, A and B. The distinguishing characteristic of this formula is that percentage changes are calculated based on the initial values of each variable. This is much simpler than the midpoint formula, which is based on the percentage change from an average of the initial and ending values. The primary problem with the endpoint formula is that different elasticity values are obtained for price increases than for price decreases of the same segment of the demand curve.

AGGREGATE EXPENDITURES The total expenditures on gross domestic product undertaken in a given time period by the four sectors--household, business, government, and foreign.

In particular, aggregate expenditures are combined with the price level as aggregate demand.
