O presente trabalho tem por objeto o estudo dos conhecimentos obtidos de forma fortuita, através da realização legal de um meio de obtenção de prova autorizado judicialmente, que não se reportam ao crime cuja investigação legitimou a medida restritiva. A fim de viabilizar essa abordagem foi necessário rever alguns conceitos relacionados à noção de prova no processo penal, que se colocam como pontos de partida para o enfrentamento do assunto. Na sequência, os conhecimentos fortuitos são inseridos no tema da obtenção da prova criminal, ligada à proteção da intimidade e da privacidade, tendo como foco principal a interceptação das comunicações telefônicas e a busca domiciliar. Para tanto, toma-se em consideração o princípio da especialidade da prova, que justifica que a limitação a direitos fundamentais esteja restrita e vinculada à apuração do crime que ensejou tal intervenção, motivo pelo qual o direito ao sigilo das comunicações e o direito à inviolabilidade da intimidade e do domicílio são analisados sob a perspectiva do panorama constitucional e legal brasileiro. A questão passa necessariamente pela análise do tema no Direito Comparado e pelo levantamento das diversas manifestações encontradas na doutrina e na jurisprudência nacional sobre a problemática, sobretudo em razão do silêncio legislativo quanto à solução jurídica da questão no ordenamento pátrio. Assim, após afastar as teses que defendem a negação absoluta dos conhecimentos fortuitos ou sua valoração sem restrições, conclui pela necessidade de se delimitar as fronteiras entre os conhecimentos imputados à própria investigação e aqueles que, inversamente, se levam em conta de conhecimentos fortuitos, socorrendo-se para tanto de um critério objetivo que concretize essa distinção. Isto porque, dela dependerá o tratamento a ser conferido aos conhecimentos obtidos em investigação de crime diverso, no que se refere à sua admissibilidade no processo e sua valoração pelo julgador como elemento de prova, apto à demonstração do delito casualmente descoberto, ou sua eventual utilização como mera notícia de crime formadora de indício. Por fim, são enfrentadas questões específicas suscitadas durante o desenvolvimento do estudo, e que colocam à prova o critério adotado. / The present paper has as its aim the study of knowledge obtained from fortuitous way through a legal means of obtaining evidence legally authorized, that does not relate to the crime which investigation legitimized the restraint measure. In order to make this approach it was necessary to review some concepts related to the notion of evidence in criminal proceedings, which arise as starting points for the confrontation of the subject. In the continuation, the fortuitous knowledge is inserted into the topic of obtaining criminal evidence, linked to the protection of privacy and intimacy, having as its main focus the interception of telephone communications and home search. To do so, it is taken into account the principle of specialty of evidence, which justifies that limiting the fundamental rights is restricted and tied to the investigation of the crime that resulted in such an intervention, which is why the right to confidentiality of communications and the right to inviolability of domicile and intimacy are analyzed from the perspective of constitutional and legal Brazilian panorama. The question goes necessarily through by examining the topic in Comparative Law and the survey of various manifestations found in doctrine and national case law on the issue, especially in view of the legislative silence as to the legal solution of the matter in land use. So, after removing the arguments defending the absolute denial of the fortuitous knowledge or its valuation without restrictions, it is concluded by the need to delimit the boundaries between imputed knowledge to the research itself and those that, conversely, are taken into account of fortuitous knowledge, helping to as much of an objective criterion that achieves this distinction. This is because from it will depend the treatment to be given to information obtained in the investigation of crime, as regards its admissibility in the process and its valuation by the Court as evidence to the demonstration of the offense or its possible use discovered fortuitously as mere forming crime news clue. Finally, specific issues are faced raised during the development of the study, and that put to the test the adopted criterion.

Notre société étant plus dépendante que jamais au vecteur électrique, la moindre perturbation du transport ou de l’acheminement de l’électricité a un impact social et économique important. La fiabilité et la sécurité des réseaux électriques sont donc cruciales pour les gestionnaires de réseaux, en plus des aspects économiques. De plus, les réseaux de transport sont interconnectés pour réduire les coûts des opérations et pour améliorer la sécurité. Un des plus grand défis des gestionnaires des réseaux de transport est ainsi de se coordonner avec les réseaux voisins, ce qui soulève des problèmes liés à la taille du problème, à l’interopérabilité et à la confidentialité des données.Cette thèse se focalise principalement sur la sécurité des opérations sur les réseaux électriques, c’est pourquoi l’évolution des principales caractéristiques des blackouts, qui sont des échecs de la sécurité des réseaux, sont étudiés sur la période 2005-2016. L’approche de cette étude consiste à déterminer quelles sont les principales caractéristiques des incidents de ces 10 dernières années, afin d’identifier ce qui devrait être intégré pour réduire le risque que ces incidents se reproduisent. L’évolution a été étudiée et comparé avec les caractéristiques des blackouts qui se sont produit avant 2005. L’étude se focalise sur les préconditions qui ont mené à ces blackouts et sur les cascades, et particulièrement sur le rôle de la vitesse des cascades. Les caractéristiques importante sont extraites et intégrées dans la suite de notre travail.Un algorithme résolvant un problème préventif d’Optimal Power Flow avec contraintes de sécurité (SCOPF) de manière distribuée est ainsi développé. Ce problème consiste en l’ajout de contraintes qui assure qu’après la perte de n’importe quel appareil d’importance, le nouveau point d’équilibre, atteint suite au réglage primaire en fréquence, respecte les contraintes du système. L’algorithme développé utilise une décomposition fine du problème et est implémenté sous le paradigme multi-agent, basé sur deux catégories d’agents : les appareils et les bus. Les agents sont coordonnés grâce à l’ « Alternating Direction Method of Multipliers (ADMM)» et grâce à un problème de consensus. Cette décomposition procure l’autonomie et la confidentialité nécessaire aux différents acteurs du système, mais aussi, un bon passage à l’échelle par rapport à la taille du problème. Cet algorithme a aussi pour avantage d’être robuste à n’importe quelle perturbation, incluant la séparation du système en plusieurs régions.Puis, pour prendre en compte l’incertitude sur la production créée par les erreurs de prédiction des fermes éoliennes, une approche distribuée à deux étapes est développée pour résoudre un problème d’Optimal Power Flow avec contraintes probabilistes (CCOPF), d’une manière complétement distribuée. Les erreurs de prédiction des fermes éoliennes sont modélisées par des lois normales indépendantes et les écarts par rapport aux plannings de production sont considérés compensés par le réglage primaire en fréquence. La première étape de l’algorithme a pour but de déterminer des paramètres de sensibilités nécessaires pour formuler le problème. Les résultats de cette étape sont ensuite des paramètres d’entrée de la seconde étape qui, elle, résout le problème de CCOPF. Une extension de cette formulation permet d’ajouter de la flexibilité au problème en permettant la réduction de la production éolienne. Cet algorithme est basé sur la même décomposition fine que précédemment où les agents sont également coordonnés par l’ADMM et grâce à un problème de consensus. En conclusion, cet algorithme en deux étapes garantit la confidentialité et l’autonomie des différents acteurs, et est parallèle et adaptée aux plateformes hautes performances. / Our societies are more dependent on electricity than ever, thus any disturbance in the power transmission and delivery has major economic and social impact. The reliability and security of power systems are then crucial to keep, for power system operators, in addition to minimizing the system operating cost. Moreover, transmission systems are interconnected to decrease the cost of operation and improve the system security. One of the main challenges for transmission system operators is therefore to coordinate with interconnected power systems, which raises scalability, interoperability and privacy issues. Hence, this thesis is concerned with how TSOs can operate their networks in a decentralized way but coordinating their operation with other neighboring TSOs to find a cost-effective scheduling that is globally secure.The main focus of this thesis is the security of power systems, this is why the evolution of the main characteristics of the blackouts that are failures in power system security, of the period 2005-2016 is studied. The approach consists in determining what the major characteristics of the incidents of the past 10 years are, to identify what should be taken into account to mitigate the risk of incidents. The evolution have been studied and compared with the characteristics of the blackouts before 2005. The study focuses on the pre-conditions that led to those blackouts and on the cascades, and especially the role of the cascade speed. Some important features are extracted and later integrated in our work.An algorithm that solve the preventive Security Constrained Optimal Power Flow (SCOPF) problem in a fully distributed manner, is thus developed. The preventive SCOPF problem consists in adding constraints that ensure that, after the loss of any major device of the system, the new steady-state reached, as a result of the primary frequency control, does not violate any constraint. The developed algorithm uses a fine-grained decomposition and is implemented under the multi-agent system paradigm based on two categories of agents: devices and buses. The agents are coordinated with the Alternating Direction method of multipliers in conjunction with a consensus problem. This decomposition provides the autonomy and privacy to the different actors of the system and the fine-grained decomposition allows to take the most of the decomposition and provides a good scalability regarding the size of the problem. This algorithm also have the advantage of being robust to any disturbance of the system, including the separation of the system into regions.Then, to account for the uncertainty of production brought by wind farms forecast error, a two-step distributed approach is developed to solve the Chance-Constrained Optimal Power Flow problem, in a fully distributed manner. The wind farms forecast errors are modeled by independent Gaussian distributions and the mismatches with the initials are assumed to be compensated by the primary frequency response of generators. The first step of this algorithm aims at determining the sensitivity factors of the system, needed to formulate the problem. The results of this first step are inputs of the second step that is the CCOPF. An extension of this formulation provides more flexibility to the problem and consists in including the possibility to curtail the wind farms. This algorithm relies on the same fine-grained decomposition where the agents are again coordinated by the ADMM and a consensus problem. In conclusion, this two-step algorithm ensures the privacy and autonomy of the different system actors and it is de facto parallel and adapted to high performance platforms.

In order to discuss these conceptions, a historical-critical approach was chosen. We believe this approach should enable the reader a clearer perception of what is at stake, namely, the passage of a deterministic vision for an indeterministic worldview. Hence we will take a route we intend to present the modern scientific thinking from its genesis to mid 20th century. As Michel Paty tells us in his article entitled The genesis of physical causality2, (published in the journal Studia Scientiae): the notions or categories of causality and determinism have accompanied the formation of modern sciences, foremost, the Physical Science one . At the time of Galileo, Descartes and Newton, physics was called Natural Philosophy and comprised a search laws of Nature expressed through regularities and causal relations. Although the notion or idea of causality were always present in Western Thought since Greek times it could be mainly found merged with metaphysical conceptions. Aristotle, for example, in his work entitled Metaphysics, lists four causes, namely, material cause, formal cause, efficient cause and final or teleological cause. According to Paty, it was due to d Alembert s Traité de dynamique more than Newton s Principia the idea of a physical causality subsumed to a mathematical functional relation (differential temporal causality), in the sense of efficient cause, that took shape. It was this conception, excluding other causes, says Paty, that prevailed in Modern Science, from the 18th century, Hume s time. The success achieved by Newtonian synthesis, expressed in its analytical form by d Alembert, led to the belief in determinism, expressed in Laplace s saying. With the advent of the theory of evolution by natural selection in the biological sciences of the 19th century, many thinkers considered that living being built up as something irreducible, which could not be explained solely in terms of efficient cause, therefore it would be necessary to resort to some kind of life force or vital breath inflated by an intelligent intention and only by him. Hence the need to resort to the final or teleological causes. Peirce was one of these thinkers, as we will have the opportunity to see along the exposition of his philosophy. We take as theoretical basis of our research the following works: 2 PATY, Michel. The genesis of physical causality . In Scientiae Studia, São Paulo, vol. 2, n. 1, 2004, p. 9.

X A Treatise of Human Nature, Enquiries Concerning Human Understanding and the Principles of Moral and An Abstract of a Treatise of Human Nature by David Hume, besides the works of two commentators, namely, The Hume s Skepticism by Plínio Junqueira Smith and Hume and the Epistemology by João Paulo Monteiro. In the same way, Regarding Peirce s works, we have taken the following works: The Essential Peirce, vol. 1; The Essential Peirce, vol. 2; Illustrations of the Logic of Science; Semiotics; Semiotics and Philosophy and the works by three commentators, namely, Kósmos Noetós by Ivo Assad Ibri; The Induction from Aristotle to Peirce, by Maria de Lourdes Bacha; Charles S. Peirce s Evolutionary Philosophy by Carl Hausman / O presente trabalho tem por objetivo realizar um estudo das concepções de causalidade em David Hume, filósofo empirista escocês do século XVIII, e em Charles Sanders Peirce, filósofo pragmatista americano do século XIX. Abordaremos estas concepções através de um enfoque de caráter histórico-crítico. Acreditamos que esta abordagem deva possibilitar ao leitor uma percepção mais clara do que está em jogo, a saber, a passagem de uma visão determinista para uma visão indeterminista do mundo. Para tanto, faremos um percurso no qual pretendemos apresentar o pensamento científico moderno, desde sua gênese até meados do século vinte. Como nos diz Michel Paty em um artigo publicado na Revista Scientiae Studia intitulado A gênese da causalidade física1, as noções ou categorias de causalidade e determinismo acompanharam a formação das ciências modernas e, em primeiro lugar, da física . Na época de Galileu, Descartes e Newton a física era denominada filosofia natural e compreendia uma busca de leis da Natureza expressa através de regularidades e relações causais. Embora a concepção ou ideia de causalidade sempre estivesse presente no pensamento ocidental desde a Antiguidade grega, ela encontrava-se mesclada com concepções metafísicas. Aristóteles, por exemplo, em sua Metafísica, relaciona quatro causas, a saber, causa material, causa formal, causa eficiente e causa final ou teleológica. Segundo Paty, foi com d Alembert, no seu Traité de dynamique, mais do que com os Principia de Newton, que a ideia de uma causalidade física subsumida a uma relação matemática funcional (causalidade temporal diferencial), no sentido de causa eficiente, ganhou forma. Foi esta concepção, excluindo outras causas, diz-nos Paty, que prevaleceu na Ciência Moderna, a partir do século XVIII, época de Hume. O sucesso alcançado pela síntese newtoniana, expressa em sua forma analítica por d Alembert, levou à crença no determinismo expresso no célebre dito de Laplace. Com o advento da teoria da evolução por seleção natural, nas ciências biológicas do século XIX, muitos pensadores consideraram que o ser vivo constituía-se como algo irredutível, que não poderia ser explicado somente em termos de causas eficientes e, portanto, seria necessário recorrer-se a uma espécie de força vital ou sopro vital insuflado por um propósito inteligente, e apenas por ele. Donde a necessidade de recorrer-se à causa final ou teleológica. Peirce foi um desses pensadores, como teremos a oportunidade de ver na 1 PATY, Michel. A gênese da causalidade física .

Tomamos como fontes básicas de nossa pesquisa as obras: Tratado da Natureza Humana, Investigações sobre o entendimento humano e os princípios da moral e Sumário do Tratado da Natureza Humana de David Hume, além das obras de dois comentadores de Hume, a saber, O ceticismo de Hume, de Plínio Junqueira Smith e Hume e a Epistemologia de João Paulo Monteiro. Com relação a Peirce tomamos as seguintes obras: The Essential Peirce, vol. 1; The Essential Peirce, vol. 2; Ilustrações da Lógica da Ciência; Semiótica; Semiótica e Filosofia e as obras de três comentadores, a saber, Kósmos Noetós de Ivo Assad Ibri, A Indução de Aristóteles a Peirce de Maria de Lourdes Bacha e Charles S.

In this work, I propose to interpret different senses of the concept of chance that can be found in the work of the author, seeking to read them again in light of his philosophical system. I advocate, too, the hypothesis that Chance, one of the main concepts of peircean philosophy, must be interpreted from the systemic perspective of his work and in light of modern theories of complexity. I proposed, as a justification for this research, to make a contribution that will support an understanding of various aspects of peircean metaphysics, given the consideration that the concept of Chance, so present in contemporary scientific literature, is worked in an innovative and, we can say, pioneering way by the author. In the development of this work, I adopted, always, the criterion of reference to Peirce s original work, also referring to the scholarly literature concerning the theme in question / O tema desta tese é o conceito de Acaso na filosofia do pensador norte-americano Charles Sanders Peirce (1839-1914), associado à doutrina que ele denomina Tiquismo. Propomo-nos, neste trabalho, interpretar sentidos diferentes da noção de acaso encontráveis na obra do autor, buscando relê-los à luz de seu sistema filosófico. Defendemos, também, a hipótese de que o Acaso, um dos principais conceitos da filosofia peirciana, deve ser interpretado sob uma perspectiva sistêmica de sua obra e à luz das modernas teorias da complexidade. Supomos, como justificativa da presente pesquisa, trazer uma contribuição que venha subsidiar o entendimento de aspectos da metafísica peirciana, a par da consideração de que o conceito de Acaso, tão presente na literatura cientifica contemporânea, ser trabalhado de forma inovadora e, pode-se dizer, pioneira, pelo autor. No desenvolvimento do trabalho, adotamos, sempre, o critério de remissão à obra original de Peirce, recorrendo também à literatura de comentários afeita ao tema em pauta

Fundação Carlos Chagas Filho de Amparo a Pesquisa do Estado do Rio de Janeiro / A responsabilidade civil do advogado é um tema que merece destaque sob a perspectiva civil constitucional. A abrangência dessa relação jurídica pelo Código de Defesa do Consumidor e a natureza negocial multiforme da relação estabelecida entre o advogado e o cliente, cuja normativa deve ser estabecida tendo em vista o caso concreto, são pontos de destaque desse trabalho, assim como a aplicabilidade do consentimento informado. Nessa toada, pretende-se conferir o enfoque funcional a partir da releitura das classificações tradicionais da responsabilidade civil em contratual, extracontratual, subjetiva, objetiva e entre as obrigações de meio e resultado para em seguida, analisarmos das hipóteses mais frequentes de responsabilização, quais sejam: a perda de uma chance, o abuso do direito processual e a reversão de liminares revertidas ao final do processo. Por fim, dentre as tendências de prevenção e precaução de danos da responsabilidade civil, revela-se a formalização de seguros de responsabilidade profissional para advogados. / Liability of attorney is a topic that deserves attention from the perspective of the constitutional civil measure. The scope of this legal relationship by the Consumer Protection Code and the nature of multifaceted relationship between lawyer and client, whose rules must be developed further in view of the case, are highlights of this work, as well as the applicability of informed consent. In this tune, it is intended to confer the functional approach from the rereading of traditional classifications of liability in contract, tort, subjective, objective, and between the obligations of means and results to then analyze the most common assumptions of accountability, which are: the loss of a chance, the abuse of procedural law and the reversal of court orders reversed at the end of the process. Finally, among the trends of precaution and prevention of damage to civil liability, it is the formalization of professional liability insurance for lawyers.

Aux XVIe et XVIIe siècles, avec la lecture des œuvres d’Achille Tatius et Héliodore d’Émèse, auteurs grecs des premiers siècles de l’ère chrétienne, les auteurs espagnols redécouvrent un genre particulier qui sera qualifié tantôt de romand’aventures, tantôt de roman byzantin. Tant l’appellation de roman que la qualification de byzantin sont fautives puisqu’il s’agit en fait de récits poétiques ou en prose antérieurs à la fin du IVe siècle, c’est-à-dire antérieurs à ce qu’il est convenud’appeler historiquement l’ère byzantine. Pour notre part, nous retiendrons l’appellation de roman néo-hellénistique ou roman néo-grec espagnol – voire « roman baroque », à l’instar de Georges Molinié1 – pour qualifier le nouveau genreromanesque créé à partir de ces récits. Nous voyons dans ce genre le développement d’une littérature en adéquation avec les exigences éthiques et esthétiques de l’« utile dulci » horacien. Influencé par le contexte politico-religieux de la Contre-Réforme, le roman néo-grec espagnol ou roman baroque expose de manière plus ou moins patente le thème de la diatribe à propos du libre arbitre et de la prédestination. Le rôle joué au cœur de ces romans par la Providence et le Destin, en particulier sous leur forme emblématique, semble empreint de l’enseignement des dogmes catholiques défendus lors du Concile de Trente. Dans les quatre ouvrages du corpus (El peregrino en su patria de Lope de Vega, Los trabajos de Persiles y Sigismunda de Miguel de Cervantès, Historia de Hipólito y Aminta de Francisco de Quintana, El Criticón de Baltasar Gracián), le problème du déterminisme et celui du salut sont de nombreuses fois soulevés. Cela se produit soit dans des discussions entre les personnages, soit dans le cours même de l’intrigue par l’apparition de phénomènes de prédiction astrologique ou autre mettant en cause les notions de Fortune et de Destin. De la même façon, les personnages, par leur manière d’être et d’agir, évoquent la notion de libre arbitre soulignant ainsi l’importance des actes qu’ils accomplissent pour assurer leur salut. / In the sixteenth and seventeenth centuries, thanks to the writings of Achilles Tatiusand Heliodorus of Emesa, two Greek authors who lived the first centuries of the Christian era, the Spanish writers rediscover a new particular genre. Those books are either labeled as adventure novels or Byzantine novels. Both the terms “novel” and “Byzantine” are inadequate since those books deal with storylines in prose or in verse dating back to the end of the fifth century, that is to say prior to what is commonly and historically termed as the Byzantine era. We will stick to the expressions “Spanishand Greek novel” or “Baroque novel” as taken up by Georges Molinié in order to label this new fictional genre in which we can perceive the development of a literature more in terms with the ethic and a esthetic standards of the Horacian « utile dulci ».Influenced by the political and religious frame of the Counter Reformation, the Spanish and Greek novel or « Baroque novel » exposes in an underlying way the theme of the diatribe about free will and predestination. The role played byProvidence and Fate in those novels, in particular under their emblematic form, is revealing of the Catholic dogmas defended during the Council of Trent. In the four books of the corpus (El peregrino en su patria by Lope de Vega, Los trabajos de Persiles y Sigismunda written by Miguel de Cervantes, Historia deHipólito y Aminta by Francisco de Quintana, Baltasar Gracian’s El Criticón) the issues of determinism and salvation are being raised. This occurs either during thedialogues, or in the development of the plot through the appearance of phenomena of astrological prediction or of other natures dealing with the notions of Fortune and Destiny. In the same way, the characters – through the way they act and behave –evoke the notion of free will, thus underlining the importance of the actions they accomplish in order to secure their salvation.

人們常為了達成各種目標而加入團體。然而，團體工作效率低落的批評，卻屢見不鮮。實證研究也發現個人在團體中的確會有偷懶的行為，而導致團體無法完全發揮其潛力。這種個人在團體中的努力程度比不上單獨一人工作時的努力程度，而且團體人數愈多，個人努力程度愈趨下降的現象，社會心理學家稱之為社會閒散(social loafing)。 　　為了更進一步瞭解人們在團體中工作表現，本研究以實驗室實驗法，探討下列三個變項對團體中個人工作表現的影響：(1)工作情境（個人成績、團體成績）；(2)工作次數（一次、二次、四次）；(3)人際親疏（情感性關係、工具性關係）。採用的活動是電腦英文文獻書目的校對工作。測量的依變項為受試者所挑出的錯誤個數、正確的反應率、漏失的反應率、假警報的反應率、以及漏失反應個數及假警報反應個數之和。 　　研究結果發現：以「正確反應率」及「漏失反應率」做為工作表現指標時，皆發現有社會閒散現象，即在個人成績情境下的工作表現優於團體成績情境。在有關「假警報反應」的指標中顯示：當工作次數愈多時，情感性關係組受試所找出的假警報反應較多，而工具性關係組的受試者卻愈少。此外，以「漏失反應個數與假警報反應個數之和」為依變項時，發現當成績團體計算，而且只有一次工作機會時，工具性關係的團體較情感性關係的團體容易產生偷懶的現象，並且當工作機會次數增加時，工具性關係的受試者會愈來愈偷懶。此外，工具性關係的受試者在只要工作一次時，社會閒散現象會相當明顯。至於人際親疏與工作次數之主要效果，則皆未達顯著差異。根據上述結果，研究者最後討論了本研究的意義與限制，並對未來研究及社會大眾提出建議。

La thèse étudie, dans des situations concrètes caractérisées par l'incertitude, plusieurs facteurs qui influencent les jugements de probabilités et les décisions. Les deux premiers essais portent sur la décision de participer à une loterie dont le nombre de participants est inconnu. La décision n'est pas influencée par le nombre de prix, c'est-à-dire le nombre de gagnants qui seront récompensés (Essai 1), alors qu'elle l'est par la similarité avec les gagnants précédents, un facteur logiquement non pertinent (Essai 2). L'insensibilité des consommateurs au nombre de prix découle de l'effet combiné de la faible évaluabilité de cet attribut et de la prise de décision sans estimation de probabilité. La similarité avec les gagnants précédents augmente l'intention de participer en raison du biais de " Hot Hand " interpersonnelle : les consommateurs pensent que leurs chances de gagner le prochain tirage sont plus élevées quand ils sont semblables aux gagnants précédents que quand ils sont dissemblables. L'essai final montre comment le fait de regretter une décision avant que ses conséquences soient connues peut conduire à être optimiste sur ces conséquences, pourvu que l'importance de cette décision pour la personne reste limitée

This thesis contain three chapters. Default Risk in Corporate Bond Pricing. This chapter provides a model for how the corporate bond default risk influences the systematic risk and an empirical analysis of the systematic and idiosyncratic parts of U.S. corporate bond returns during 2001-2005. The average corporate bond beta is low and positive (0.06). Investment grade bonds have negative betas (between - 0.01 and -0.13) and non-investment grade bonds have positive betas (between 0.11 and 1.48), but both groups have similar within groups systematic risks. When controls for interest rate and liquidity risks are introduced there are still remaining default probabilities, implying that the default risk is in part systematic and in part idiosyncratic.   Returns to Defaulted Corporate Bonds.   In the second chapter short term excess returns in a sample of 279 defaulted US corporate bonds are tested for using multiple regression analysis. There are robust excess returns after controlling for market and liquidity risk. The expected recovery rate during 2001-2006 is estimated to be, on average, four percentage points lower the first month after default than the present value of the recovery rate after nine months. Capital Structure Choices.   The trade-off and pecking order theories are tested using both established tests from the literature and new tests. The main contributions of this chapter are the new tests of financing of operating net assets (for the pecking order theory), the mean reversion tests (for the trade-off theory) and the test of mean reversion and trends. These tests allow for extended conclusions on the validity of the pecking order versus the tradeoff theory. / <p>Diss. Stockholm : Handelshögskolan, 2008 Sammanfattning jämte 3 uppsatser</p>
