PERFECT COMPETITION CHARACTERISTICS: The four key characteristics of perfect competition are: (1) large number of small firms, (2) identical products sold by all firms, (3) freedom of entry into and exit out of the industry, and (4) perfect knowledge of prices and technology. These four characteristics mean that a given perfectly competitive firm is unable to exert any control whatsoever over the market.

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.
