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.

TOTAL-MARGINAL RULE: A mathematical connection between a marginal value is the slope of a curve of the corresponding total value stating that the marginal IS the slope of the total curve. If the total curve has a positive slope (that is, is upward sloping), then marginal is positive. If the total product has a negative slope (downward sloping), then marginal is negative. If the total curve has a zero slope (horizontal), then marginal is zero. Moreover, if the total curve has an increasing slope (becoming steeper), then the marginal is rising. If the total curve has a decreasing slope (becoming flatter), then the marginal is falling.

ALTERNATIVE UNEMPLOYMENT RATES The official unemployment rate estimated and reported monthly by the Bureau of Labor Statistics (BLS) using data from Current Population Survey is one of six alternative measures of unemployment tracked and reported by the BLS, officially labeled sequentially U1 through U6. The "official" unemployment rate is U3. The other five measures seek to document different ways in which labor can be under utilized, including unemployment duration, job losers, discouraged workers, marginal workers, and part-time workers.
