Abstract

In recent years, theoretical economists have begun to examine the effects of imperfect information on the existence, uniqueness, and efficiency of market equilibria, both in labor markets and in consumer product markets. Two significant conclusions can be drawn from this literature: (1) the properties of market equilibria are extremely sensitive to the search strategies used by consumers or workers, and (2) the key to “stabilizing” markets at price or wage distributions which are competitive in an appropriate sense is direct comparison shopping. With direct comparison shopping, consumers, for example, actually compare brands to each other and choose the best from those that they have seen. Economists commonly assume that consumers search by defining a hypothetical reservation (or cutoff) level against which brands or jobs are compared sequentially. Economic theory, however, is not (or at least has not been) very useful in identifying which search strategies are appropriate to specific informational settings. Moreover, since consumers and workers who face positive information acquisition costs are likely to choose a “satisfactory” alternative rather than an “optimal” one, the issue of which search strategies people should use may only be resolvable empirically.
