O estudo, de caráter qualitativo, se fundamenta na abordagem bioecológica de desenvolvimento humano de Bronfenbrenner (1996), cuja ênfase está na interconexão entre vários níveis do sistema ecológico. É uma abordagem que privilegia estudos em ambientes naturais que contemplem a realidade cotidiana vivenciada pelos sujeitos envolvidos - considerando estes em suas particularidades, bem como os ambientes nos quais estão inseridos. Dessa forma, a presente pesquisa possibilitou a inserção da pesquisadora no campo para coletar informações e poder dar ênfase ao olhar de crianças matriculadas no primeiro ano do ensino fundamental, para além da visão de seus pais e professores. Sendo assim, foram realizadas observações e entrevistas semi-estruturadas, com o objetivo principal de constatar situações de práticas e apreender as percepções dos sujeitos envolvidos com o ingresso no ensino fundamental. A pesquisa foi desenvolvida em uma escola municipal de uma cidade do interior paulista, que atende estudantes do ensino fundamental. A coleta de dados ocorreu no período de março a agosto de 2008. Somaram-se trinta e três o número de sujeitos deste estudo: três professoras atuantes no 1º ano do ensino fundamental, quinze crianças deste mesmo ano e quinze responsáveis destas (pais e/ou mães, neste caso). As observações... / From the approval of the Law 11.114, released in 05/16/05, which established that the sixyear- old children were enrolled in fundamental school - and considering that the family and the school are the most relevant contexts in a child’s life - the aim of this work was to notice how the first year of the nine-year fundamental teaching takes place, and also, how the main involved – children, parents and teachers – notice the procedure. The quality study is based in the bioecological approach of Bronfenbrenner’s human development, which emphasizes the interconnection among several levels of the ecological system. It’s a kind of approach that privileges studies in natural atmospheres that contemplate the daily reality lived by the involved characters – considering them in their features, as well as the atmospheres in which they’re inserted. This way, the present research enabled the researcher’s inset to get information and be able to emphasize the look at the children who were enrolled in the first year of the fundamental reaching, for a further vision of their parents and teachers. So, remarks and semi-structured interviews were carried out, with the main goal of noticing practical situations and learning the perceiving of the characters involved in the entrance in the fundamental teaching. The research was carried out at a Town hall school in a city in the countryside of São Paulo state, which deals with fundamental teaching students. The data collection happened from March to August in the year 2008. The number of characters in this study was thirty-six: three teachers of the first year of fundamental teaching, fifteen children at the same course, and their fifteen fathers and mothers. The observations inside the classroom were carried out during the research time, and focused the situations in regular classes and other moments that surround the school...

Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Na busca por entender de que forma profissionais de contabilidade estão analisando e repassando informações, o objetivo geral do trabalho é mostrar o processo de decisão em ambiente contábil sob a ótica da Teoria dos Prospectos, buscando demostrar que as decisões, são baseadas principalmente em julgamentos, contribuindo para consciência das imperfeições dos julgamentos e decisões. O objetivo específico é testar de que forma os efeitos Framing, e Certeza podem moldar uma tomada de decisão dentro do ambiente contábil. Sendo uma pesquisa descritiva, aplicou-se questionário estruturado e não disfarçado à profissionais da área de Contabilidade. O questionário foi dividido em dois tipos (I e II), dividindo assim o campo dos ganhos e das perdas. Procurou-se através da análise do resultado dos questionários evidenciar o impactos dos efeitos nesses profissionais. Dentre o resultado, pode-se constatar que de maneira geral as questões que envolvem certeza no campo dos ganhos são as mais procuradas entre os respondentes. É possível identificar a presença do Efeito Framing. Em relação ao gênero, é possível identificar maior impacto do Efeito Framing nos homens que nas mulheres. Os Efeitos Certeza e Pseudocerteza se fazem presentes em ambos os gêneros o que demostra certa cautela frente a tomada de decisão. Através desse estudo buscou-se auxiliar os decisores na tarefa de repensar seus atuais processos de tomada de decisão, por meio da conscientização de que são dotados de uma racionalidade limitada e que seus julgamentos são passivos de desvios. / In seeking to understand how accounting professionals are analyzing and transmitting information, the aim of this work is to show the decision-making in accounting environment from the perspective of Prospect Theory, seeking to demonstrate that decisions are based primarily on judgments, contributing to awareness of the imperfections of the judgments and decisions. The specific objective is to test how the effects Framing, and Certainty can shape decision-making within the accounting environment. As a descriptive study, we applied a structured questionnaire and did not disguise the accounting professionals. The questionnaire was divided into two types (I, II), thus dividing the field of gains and losses. Was sought by examining the results of the questionnaires show the impact of these effects professionals. Among the results, one can see that in general the issues involved in the field of sure gains are the most sought after among the respondents. You can identify the presence of Framing Effects. Regarding gender, it is possible to identify the greatest impact Framing Effect in men than in women. The Effect Certainty are present in both sexes which demonstrates caution before making a decision. Through this study we sought to assist decision makers in the task of rethinking their current decision-making processes, through the awareness that they are endowed with a bounded rationality and that their judgments are passive deflections.

[pt] Este trabalho analisou o desempenho de 31 fundos mútuos comportamentais atuantes nos EUA, Europa e Japão descritos em Santoni e Kelshiker (2010). Foram observados os desempenhos dos fundos e seus respectivos Benchmarks em quatro indicadores: Índice de Sharpe, Índice de Sortino, Medida Ômega e Medida de Desempenho Comportamental. O horizonte da análise foi de 10 anos (jan/04 a dez/14) dividido em intervalos de 6, 12, 36, 60 e 120 meses. A partir da consolidação dos indicadores os fundos foram ranqueados e classificados em três faixas de desempenho: superior, intermediário e inferior. No intervalo de 120 meses não houve, na média geral, diferença de desempenho significativa (a 5 por cento) entre os fundos e os Benchmarks. A análise por intervalos indicou que o desempenho dos fundos em relação aos Benchmarks piora conforme aumenta o prazo de aplicação. Nos intervalos mais curtos (6 e 12 meses) não houve, na média, diferença de desempenho significativa enquanto nos prazos mais longos (36 e 60 meses) o desempenho médio dos fundos foi significativamente inferior aos Benchmarks. Na média de todos os intervalos o desempenho médio dos fundos foi significativamente inferior aos Benchmarks. Dentre os indicadores utilizados, o índice de Sortino foi o que apresentou maior correlação com o desempenho geral dos fundos. / [en] This work has analyzed the performance of 31 behavioral mutual funds operating in USA, Europe and Japan, as described in Santoni and Kelshiker (2010). It has been observed the performance of the funds and their respective Benchmarks according to four measures: Sharpe Index, Sortino Index, Omega Measure and Behavioral Performance Measure. The analysis covered a 10-year period (jan-04 to dec-14) split into intervals of 6, 12, 36, 60 and 120 months. Based on the consolidation of the performance measures, the funds have been ranked and classified into three performance categories: upper, intermediate and lower. In the 120-month interval there has not been, on average, a significant difference (at 5 per cent) in performance between funds and Benchmarks. The analysis by intervals showed that the funds performance worsens in relation to the Benchmarks as the investment period increases. In shorter intervals (6 and 12 months) there has not been, on average, a significant difference in performance while in the longer intervals (36 and 60 months) the funds average performance was significantly lower than the Benchmarks. Computing the mean of all intervals, the funds average performance was significantly lower than the Benchmarks. Among the performance measures used, the Sortino Index presented the highest correlation with the general performance of the funds.

This thesis investigates the choices under risk in the framework of non-expected utility theories. One of the key contributions of this thesis is providing an approach that allows for a complete characterisation of Cumulative Prospect Theory (CPT) preferences without prior knowledge of the reference point. The location of the reference point that separates gains from losses is derived endogenously, thus, without any additional assumptions on the decision maker’s risk behaviour. This is different to the convention used in the literature, according to which, the reference point is preselected. The problem arising from imposing the location of the reference point is that the underlying preference conditions might not be alligned with the predictions made by the model. Consequently, it is difficult to verify such a model or to test it empirically. The present contribution offers a set of normatively and descriptively appealing preference conditions, which enable the elicitation of the reference point from the decision maker’s behaviour. Since these conditions are derived using objective probabilities, they can also be applied to settings such as health or insurance, where the continuity of the utility function is not required. As a result, the obtained representation theorem is not only the most general foundation for CPT currently available, but it also provides further support for the use of CPT as a modelling tool in decision theory and fi…nance. Another contribution that this thesis can be credited with is an application of rank-dependent utility theory (RDU) to the problem of insurance demand in the monopoly market affected by adverse selection. The present approach extends the classical model of Stiglitz (1977) by accounting for an additional component of heterogeneity among consumers, the heterogeneity in risk perception. Speci…fically, consumers employ distinctive probability weighting functions to assess the likelihood of risky events. This aspect of consumers’' behaviour highlights the importance that the probabilistic risk attitudes within the RDU framework, such as optimism and pessimism, have for the choice of insurance contract. The analysis yields a separating equilibrium, with full insurance for a sufficiently pessimistic decision maker. An important implication of this result is that any low-risk individual who sufficiently overestimates his probability of loss will induce the uninformed insurer to o¤er him full coverage, thereby, affecting the high-risk type adversely. This outcome is consistent with the recent empirical puzzle regarding the correlation between ex-post risk and insurance coverage, according to which, agents with low exposure to risk receive a larger amount of compensation. By providing an explanation of this pattern of individual behaviour, the current work demonstrates that theory and practice of insurance demand can be reconciled to a greater extent. The paper also provides a behavioural rationale for policy intervention in the market with RDU agents, where the initial distortions in contracts due to unobservable risks are aggravated by the non-linear weighting of probability of a risky event.

This thesis aplied tools of economic analysis on situation in poker, where players choose to finish tournament or make a deal and take certain amount of money immediately. Theoretical frame consists of economic theories for decesion under risk and poker literature. Hypotheses are tested with regresion analysis on dataset which I obtain by my own observing. Estimations support hypothesis that players are risk-averze and loss-averze. In bigger tournaments are bigger prizepools and that is the reason, why players in bigger tournament make deals more often. Moreover deal is more likely, when players are approximetly equal skilled in poker.

Titre: Categorisation et évaluation de l'innovation :approche par la théorie des prospects appliquée au cas du vin allégé en alcool.Chaque année de très nombreuses innovations sont proposées sur le marché, mais seul un nombre réduit d'entre elles rencontre le succès espéré. Face à ce constat, l'une des explications avancées par la recherche marketing est la difficulté du consommateur à catégoriser un nouveau produit.Ce travail s'insère dans le courant de recherches sur la catégorisation de l'innovation et suggère de tenir compte de l'incertitude qui caractérise ce processus. L'originalité de cette étude est de proposer un lien entre les recherches sur la catégorisation de l'innovation et celles sur la prise de décision en condition d'incertitude. La Théorie des Prospects (Kahneman et Tversky, 1979) en particulier, et l'un de ses principes, celui d'aversion aux pertes, ont fourni un cadre théorique adapté pour tenir compte du caractère d'incertitude de l'innovation. Notre question de recherche a proposé de vérifier si le principe d'aversion aux pertes pouvait s'appliquer pour expliquer comment la modification de certains attributs d'une catégorie provoque la perception d'une rupture et la création d'une nouvelle catégorie de produits par le consommateur.La partie empirique de ce travail a été appliquée dans le domaine le vin, un produit qui traverse une grave crise de consommation. Nous avons retenu une approche expérimentale à travers six études conduites sur des innovations du secteur vinicole. Les résultats ont permis de mettre en évidence le rôle majeur joué par la nature de l'attribut dans la catégorisation ainsi que son influence sur la perception des ruptures d'une catégorie.Du point de vue managérial, les conclusions de ce travail ont pour objet l'efficacité des stratégies d'innovation qui agissent sur les attributs d'un produit et sur leur capacité à différencier une innovation parmi la concurrence. Cette recherche fournit également des suggestions quant au positionnement et à la communication à mettre en place pour faciliter la compréhension d'un nouveau produit et donc son choix par le consommateur. / Title: Categorization and evaluation of innovation: a prospect théory approach applied to the case of low alcohol content wine Every year numerous innovations are available on the market but only a small number meet the hoped-for success. Given this fact, one of the explanations offered by marketing research is the difficulty the consumer has to categorize a new product. This work is part of current research on the categorization of innovation and suggests to consider the uncertainty that characterizes this process. Its originality is to propose a link between research on the categorization of innovation and those of decision making under uncertain conditions. Prospect Theory (Kahneman et Tversky, 1979), in particular, and one of its principles, that of loss aversion, this research has provided a theoretical framework adapted to take into account the uncertainty of innovation. Our research question proposes to determine whether the principle of loss aversion can be applied to explain how the modification of certain attributes of a class causes the perception of a break and create a new category of products by the consumer. The empirical part of this work was conducted on wine, a product that is going through a major crisis of consumption. We chose an experimental approach across six studies conducted on innovations in the wine sector. The results were used to highlight the major role played by the nature of the attribute in the categorization and its influence on the perception of breaks in a category. From the managerial point of view, the conclusions of this work relate to the effectiveness of innovation strategies that affect the attributes of a product in their ability to differentiate an innovation from competition. This work also provides suggestions for the positioning and communication set up to facilitate the understanding of a new product and therefore its choice by the consumer.

The aim of the thesis is to afford a complex perspective of a parallel development of psychology and economics to the readers. It is suggested, how psychological experiments could be used for the overall enrichment of the classical theory of economics. In the thesis, readers are introduced to the development of economic theories over time, and also to what role a human takes as a personality. Including the thesis is the part engaging in consumer decision process.

In Nigeria, displaced non-Muslim parents living in refugee camps face difficult decisions regarding the schooling of their teenage daughters, who are potential targets of Boko Haram terrorist activities. The purpose of this interpretative phenomenological analysis (IPA) was to qualitatively explore a deeper understanding of the lived experience of displaced non-Muslim parents in Nigeria concerning the schooling of their teenage daughters. Prospect theory provided a theoretical foundation for the study. The theory holds that decision-making is based on the perceived value of gains and losses under risk conditions, rather than solely the perceived final outcome of the risk. The research questions explored how the experience of terrorism affected parents' school-related decision-making, perceptions of the schooling environment and value of education, and risk-taking attitudes. Data were collected through semistructured interviews held with 12 participants from 2 refugee camps. The data were then analyzed using the steps recommended in IPA. Identified themes included parents' experience of trauma, their concern about the vulnerability of their school-going children, and their support for their daughters' education. The findings produced a deeper understanding of the psychological implications of terrorist activities for the families, as well as their perception of the educational needs of teenage girls. Recommendations include providing governmental and nongovernmental support for affected parents and teenage girls. Contributions to positive social change include developing advocacy and resources in support of displaced parents and schools for improving the educational status of teenage girls in Nigeria.

With robo-advisors and regulation eventually changing the market conditions of thefinancial advisory industry, traditional advisors will have to adapt to a new world of asset management. Thus, it will be of interest to traditional advisors to further explore the topic of how to automatically evaluate soft aspects such as client preferences and behavior, and transform it into portfolio allocations while retaining stringency and high quality in the process. In this thesis, we show how client preferences and behavioral aspects can be translated into quantitative parameters, suitable for an asset allocation model based on prospect theory. A risk profiler, a type of questionnaire, is found to be an appropriate tool to use in this process. Further, we show that the impact of the parameters on the resulting portfolio allocations is consistent with prospect theory and the preferences of the investor. Finally, we conclude that the optimized portfolio allocation generated by the model suit the investor's preferences. / Allteftersom robotrådgivning och regleringar förändrar marknadsvillkoren för finansiellrådgivning kommer traditionella aktörer behöva anpassa sig till helt nya förutsättningar. Därmed är det av intresse för traditionella rådgivare att ytterligare undersöka hur man automatiskt kan utvärdera mjuka faktorer, såsom kunders preferenser och beteende, och omvandla dem till portföljallokeringar samtidigt som man bibehåller stringens och hög kvalitet i processen. I denna avhandling visar vi hur kundpreferenser och beteendemässiga aspekter kan översättas till kvantitativa parametrar för en allokeringsmodell baserad på prospektteori. En riskprofilerare, en typ av frågeformulär, visar sig vara ett bra verktyg att använda i processen. Vidare visas att parametrarnas effekt på de resulterande portföljerna är förenliga med prospektteori och investerarens preferenser. Slutligen drar vi slutsatsen att den optimerade allokeringen passar investerarens preferenser.
