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

ADVERTISING: Information provided about a product by a company to promote or maintain sales, revenue, and or profit. Advertising is often an explicit method of signalling that sellers use to provide information to buyers. The primary objective of advertising from the sellers perspective is to increase (or at least maintain) demand for a product. To accomplish this objective advertising provides buyers with two important types of information -- prices and product quality.
