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.

EFFICIENT INFORMATION SEARCH

A comparison between the cost of acquiring information and the benefit generated by the information such that it is not possible to increase welfare or well being by acquiring any more of any less information. Efficient information search is achieved by equating the marginal cost of search with the benefit of search. This efficiency is comparable to the profit-maximizing decision by a producer and the utility-maximizing decision by a consumer.
