EFFICIENT SEARCH, DETERMINANTS: Two factors that affect information search are (1) the amount of purchase and (2) frequency of purchase. Goods that are relatively expensive increase the potential benefit of search. For example, saving 10 percent on the purchase price of a house is significantly more than saving 10 percent on the price of bar of soap. Buyers are thus likely to undertake extensive search when buying a house, but not for soap. Goods that are purchased more frequently also don't require extensive search activities. Since buyers already know the "best places" to buy the "highest quality" products at the "lowest prices" for frequently purchased goods, little can be gained from search.

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.
