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.

CARDINAL UTILITY The notion that utility--the satisfaction of wants and needs achieved through the consumption of goods and services--can be measured with numerical values (1, 2, 3, etc.) that are based on a benchmark scale.
