The model presented herein concerns a population of consumers with purchasing decision driven by reference groups. The goal of the paper is to verify through simulations whether introduction of local interactions infl uences the results from earlier approximate models. Local interactions were introduce into the model through the use of Poisson graphs. It is showed that the results are qualitatively identical to the previous results from the approximate models. Additionally, the full distribution of producers’ market shares is estimated based on the results of simulations.
