This research aims to replicate the empirical investigation of the seminal article by Kahneman and Tversky (1979) to evaluate the decision-making process of employees (potential investors) of a major national financial institution. The results of this study were compared to those obtained in the original article and the studies led by C??rtes (2008), Cruz, Kimura and Krauter (2003), Rogers et al. (2007), Rogers, Favato and Securato (2008), and Torralvo (2010). The questionnaire adopted was an adaptation of the originally used, so that one could test, in studied sample, the applicability of Prospect Theory, more specifically with regard to Certain, Reflection and Isolation Effects. I also analyzed the differences in the decision making process considering the attributes of the respondents (gender, age, education, occupation, income and financial dependents). The results confirmed the existence of behavioral effects and proved that a large portion of the sample presented significant inconsistency in their choices according to the principles of the Expected Utility Theory, pointing that their decisions were not made under strictly rational behavior. Furthermore, in relation to violations observed, it was not possible to present significant conclusions in concern to the attributes by using regression analysis, suggesting the need of further studies / A premissa de racionalidade ilimitada preconizada pela Hip??tese dos Mercados Eficientes ?? contestada como ferramenta para tomada de decis??es pelo arcabou??o te??rico que envolve as Finan??as Comportamentais, cuja base, a Teoria da Perspectiva de Kahneman e Tversky (1979), questiona o que prediz a Teoria da Utilidade Esperada, importante elemento da Economia Neocl??ssica. A presente pesquisa objetiva replicar a investiga????o emp??rica do artigo seminal de Kahneman e Tversky (1979) para avaliar o processo decis??rio de funcion??rios (potenciais investidores) de uma importante institui????o financeira nacional. Os resultados deste estudo foram comparados aos obtidos no trabalho original e nas pesquisas realizadas por C??rtes (2008), Cruz, Kimura e Krauter (2003), Rogers et al. (2007), Rogers, Favato e Securato (2008) e Torralvo (2010). O question??rio adotado foi uma adapta????o do originalmente utilizado, para que se pudesse testar, na amostra estudada, a aplicabilidade da Teoria da Perspectiva, mais especificamente no que diz respeito aos Efeitos Certeza, Reflex??o e Isolamento. Foram analisadas, ainda, as diferen??as no comportamento frente ?? tomada de decis??es considerando os perfis demogr??ficos dos respondentes (g??nero, idade, forma????o, ocupa????o, renda e dependentes financeiros). Os resultados obtidos confirmaram a presen??a dos efeitos e comprovaram que uma grande parcela do p??blico amostral apresentou efetiva inconsist??ncia em suas escolhas segundo os fundamentos da Teoria da Utilidade Esperada, o que indica que suas decis??es n??o foram tomadas de forma estritamente racional. Al??m disso, em rela????o ??s viola????es observadas, n??o foi poss??vel apresentar conclus??es quanto ??s diferen??as entre os perfis demogr??ficos estudados por meio do modelo econom??trico proposto, apontando a necessidade da realiza????o de novos estudos

Such theme is relevant in the entrepreneurship context in Brazil, and in the theoretical body of knowledge on Entrepreneurship and Corporate Finances. Angel investment is growing in Brazil, although only a few studies about risks in such context are found. In order to reach such goals, this thesis presents a chart of risks and relevant mitigation procedures, and proposes relevant classification in accordance with the angel investment phases and prominent risk dominion, as well as an exploratory study with three experienced Brazilian angels, following a semi-structured script whose empirical findings are framed into the relevant theories. Adopted data analysis technique is content analysis.In terms of results, based on fragments extracted from the interviews, angels are mostly concerned with operational risks, followed by market, financial and technological ones. In what refers to the 38 mechanisms of risk mitigation gathered in this thesis, answers point the majority of risk mitigation strategies organized in this thesis isreflected in the experience of the interviewed angels, since 26 mitigation mechanisms are endorsed by three or two of the interviewed angels. Additionally, another 10 mitigation mechanisms out of the 38 are endorsed by one of the interviewed angels; only two out of the mentioned 38 mitigation mechanisms are not adopted by any of the interviewed angels. / O objetivo desse trabalho ?? estudar a percep????o e a mitiga????o de riscos diversific??veis por investidores-anjos em seus investimentos em startups. Tal tem??tica tem relev??ncia no contexto do empreendedorismo no Brasil e no corpo te??rico sobre o empreendedorismo e finan??as. O volume de investimentos de tal natureza cresce no Brasil e, n??o obstante, h?? poucos estudos que versam sobre riscos neste contexto. Visando a atingir tais objetivos, realiza-se quadro resumo de riscos e 38 mecanismos correspondentes de mitiga????o apontados pela literatura, com proposta de classifica????o conforme fases do investimento-anjo e dom??nio de risco preponderante, bem como se efetua estudo explorat??rio com tr??s investidores-anjos brasileiros experientes, seguindo roteiro semiestruturado,cujos dados emp??ricos s??o cruzados com as teorias pertinentes. A t??cnica de an??lise de dados utilizada ?? a an??lise de conte??do. No que se refere aos resultados obtidos, conclui-se que fragmentos dos discursos dos entrevistados revelaram preocupa????es mais frequentemente relacionada aos riscos do dom??nio operacional, seguidos de riscos de mercado, financeiros e tecnol??gicos. No que tange aos 38 mecanismos de mitiga????o agrupados no presente trabalho, as respostas dos anjos apontam que a maioria das estrat??gias de mitiga????o colacionadas neste trabalho ?? corroboradapela pr??ticados anjos entrevistados, pois 26estrat??gias s??o endossadas por tr??s ou dois dos entrevistados. Complementarmente, 10 das 38 formas de mitiga????o s??o endossadas por um dos anjos entrevistados; apenas duas das 38 formas de mitiga????o n??o encontram apelo junto aos entrevistados.

A sociological approach is used to analyze incidences of extreme opportunism in financial markets. Through an analysis of arguably the most widely publicized "rogue" trader events in recent history, a determination is made of the validity of explaining these events as aberrations, attributable to the actions of "rogues". The primary focus is the role of structural factors underlying these incidences of extreme opportunism in financial markets. A diverse range of documentary and other sources is used to avoid any form of bias as far as possible. It was found that structural factors act as countervailing forces to inhibit such behavior or as motivators and facilitators acting as catalysts for extreme opportunism. The balance between these factors largely determines the level of opportunistic behavior in a particular environment. Extreme opportunism is therefore not an aberration or "rogue" occurrence but a manageable phenomenon intrinsic to the social structural context within which it occurs. By conceptualizing these factors as countervailing forces one is forced to view structural factors, like compensation structures and formal and informal restraints, relative to one another and no longer in isolation. This realization translates into the conclusion that restraints and oversight systems for example, should be designed relative to the relevant motivators and facilitators in its area of application. In an environment where traders of highly geared financial products are motivated with multimillion USD incentive packages, a low budget oversight system and inexperienced regulatory staff, is clearly not the appropriate tools to control and manage extreme opportunism. / Criminology / D.Phil.

To achieve the general and specific objectives, it has been done interviews with managers from the educational area, managers from the capital market, and research through a questionnaire survey with students with a higher education and also a review of the literature related to financial education. The results of the research indicated that there are huge student??s interest in learning financial education; the creation of a brokerage office, or similar, within the university area was well received by educational managers as well as capital market managers, with the only requirement to combine financial practice to the theory given by the academy.
