Abstract
This chapter makes a next step toward developing the model for evaluating the risk of misinforming in more realistic settings. The market case, described by 1:N topology, explored in the first chapters of this part of the book, is valid only in a monopoly dominated trading environment. The market is described typically with M:N communication topology. This chapter extends the model to the case of 2:N – the case of assessment of risk of wrong purchase decision when there are two competing products. As above the stress is on the design of a survey that may reveal clients' attitude.
