• Resumo em Inglês: This study proposes to create a model of actors??? behavior that operates by spreading contagion in the Brazilian financial environment. To pursue that proposed model, it was essential to review literature taking into account studies from various sciences such as psychology, sociology, economics and behavioral finances. Furthermore, it was conducted a survey research in which respondents were encouraged to take a stand on realistic and possible information-based-contagion scenarios. The results were dealt with by trying to classify the investors in behavioral profiles, taking into consideration the behavioral patterns of each group. The heuristics, biases and principles of psychology and behavioral economics were analyzed considering the susceptibility of actors to certain influences. The results were assessed by experts of the economical and financial fields by means of the use of discussion group. Later, a conceptual model was created in order to shape this system which considers the main influences over investors likely to change their behavior and to produce the effect of the indirect contagion. The information, considered as one of the key aspects of the contagion, is shaped in a model that is under the influence of an environment that is subjected to noise generation, echo chambers and informational cascades. The resulting model suggests there is a relation among those elements and contributes to the study when taking into account the profile of the investors, their behavioral susceptibility and potential changes to possible overreactions such as bank withdrawals.
