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.

UTIL A hypothetical unit of measurement of utility that is commonly used by economists to present hypothetical information about utility and consumer demand theory. The util measurement unit was developed as a convenient way to illustrate and discuss concepts such as total utility, marginal utility, and the law of diminishing marginal utility. However, because utility is not a measurable characteristic, the util does represent an actual unit of measurement, such as inches or pounds.
