Abstract: The model presented herein is a variant of the original Bertrand duopoly model. The only difference comes from the more detailed model of behavior of the population of consumer. It is assumed that there is a particular distribution of reservation prices within the population. It is also assumed that consumers use a bounded-rational procedure of choice between the products. The main results are twofold. Firstly, it is shown that it is possible that equilibrium prices are higher than the marginal costs. Secondly, it is shown that there maybe two equilibrium points.
