EXCESS DEMAND: A disequilibrium condition in a competitive market in which the quantity demanded is greater than the quantity supplied, hence there's "extra" demand. Pointy-headed economists generally use the more technical term shortage rather than excess demand. The reason, of course, is that shortage has two syllables and excess demand has four. The time saved in pronouncing two syllables rather than four is a definite efficiency plus for the entire economy.

ARC ELASTICITY The average elasticity for discrete changes in two variables. The distinguishing characteristic of arc elasticity is that percentage changes are calculated based on the average of initial and ending values of each variable, rather than initial values. Arc elasticity is generally calculated using the midpoint elasticity formula. The contrast to arc elasticity is point elasticity. For infinitesimally small changes in two variables, arc elasticity is the same as point elasticity.
