POINT ELASTICITY: The relatively responsiveness of a change in one variable (call it B) to an infinitesimally small change in another variable (call it A). The notion of point elasticity typically comes into play when discussing the elasticity at a specific point on a curve.< P>Point elasticity can be calculated in a number of different ways. Sophisticated economists, using sophisticated mathematical techniques (better known as calculus) can calculate point elasticity by taking derivatives of equations. Derivatives is fancy calculus talk for infinitesimally small changes.

TWO-SECTOR AGGREGATE EXPENDITURES LINE

A graphical depiction of the relation between aggregate expenditures by the two private sectors (household and business) and the level of aggregate income or production. The two-sector aggregate expenditures line combines consumption expenditures and investment expenditures. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for the marginal propensity to invest if it is assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the three-sector aggregate expenditures line and the four-sector aggregate expenditures line.
