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.

KINKED-DEMAND CURVE ANALYSIS An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.
