Abstract

In this paper I investigate whether, in market equilibrium, one observes price dispersion and search when buyers intend to acquire several products whose price is unknown and exists a positive search cost. Although that seems fruitful, I prove that in market equilibrium it is not observed neither price dispersion nor search and shops act as if they where monopolists. Nevertheless, there is one property of the theory that is in accordance with empirical data, namely the continuous increase in the number and dimension of larger shops.
