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.

AUTONOMOUS EXPENDITURES Expenditures on aggregate production by the four macroeconomic sectors that do not depend on income or production (especially national income or even gross domestic product). That is, changes in income do not generate changes in these expenditures. Each of the four aggregate expenditures--consumption, investment expenditures, government purchases, and net exports--have an autonomous component. Autonomous expenditures are affected by the ceteris paribus aggregate expenditures determinants and are measured by the intercept term of the aggregate expenditures line. The alternative to autonomous expenditures are induced expenditures, expenditures which do depend on income.
