Previous issue date: 2017-08-11 / 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. / O presente estudo objetivou elaborar um modelo de comportamento de atores como
indutores de cont??gio no ambiente financeiro brasileiro. Para elaborar o modelo
proposto, tornou-se necess??ria a realiza????o de uma revis??o de literatura com
estudos originados de v??rias ci??ncias, tais como psicologia, sociologia, economia e
finan??as comportamentais. Al??m disso, foi realizada pesquisa do tipo survey, onde
os respondentes foram estimulados a se posicionar em cen??rios poss??veis e
realistas de cont??gio baseado em informa????es. Os resultados foram organizados de
forma a enquadrar os investidores em perfis comportamentais, levando-se em
considera????o os padr??es comportamentais de cada grupo. As heur??sticas, vieses e
princ??pios derivados da psicologia e da economia comportamental foram analisados
diante da suscetibilidade dos atores a determinadas influ??ncias. Os resultados foram
avaliados por profissionais da ??rea econ??mica e financeira mediante grupo de
discuss??o. Posteriormente, para representar esse sistema que considera as
principais influ??ncias sobre os investidores pass??veis de alterar os seus
comportamentos e de gerar o efeito do cont??gio indireto, foi elaborado um modelo
conceitual. A informa????o, como um dos elementos centrais do cont??gio, apresentase
no modelo sob a influ??ncia de um ambiente suscet??vel a gera????o de ru??dos,
c??maras de eco e cascatas informacionais. O modelo resultante sugere uma rela????o
entre esses elementos e contribui ao considerar o perfil dos investidores, a sua
suscetibilidade comportamental e potenciais mudan??as para poss??veis rea????es
exageradas, como saques banc??rios.
