Full textHealth is an important dimension in the different interactions between banks, insurance companies and SMES leaders. If the purpose displayed by the banking and insurance corporations by administering the questionnaire of health is to decrease the risks of non-payment, the heads of business aim is to find the necessary financing for the survival of their businesses. The challenge for each of the actors is important and leads deviances. The opportunism, in charge of deviant behavior adopted by stakeholders finds its genesis in the anti selection one of the effects of the asymmetry of information. The deviant and asymmetric triangulation made between the leaders of SME, banks and insurance companies on the health is a factor mattering in the management of the risk. This research aims at showing that the selection operated on the health of the leaders within the framework of the granting of credit creates pernicious effects. The incompleteness of the contracts being hardly verifiable, each of the concerned parties tries to maximize its profit by using several forms of cheating. The survival of SMES being closely linked to their financing, it appears, therefore interesting to highlight the nature of the existing lies between these organizations through the theories of deviance and the asymmetry of information

Full textThis thesis aims at studying the dynamics of energy price through the investigation of their efficiency degree and the dynamics of risk premium.To this end, this study has been structured into three chapters : The first one is theoretical while the two others are empirical. In particular, the first chapter develops the conceptual framework for this study, defines the concepts, and recalls the issues related to investment strategies and diversification opportunities on energy markets. It also discusses the related literature review. The second chapter focuses on the informational efficiency hypothesis for commodity markets in the short and long terms using several parametric and non-parametric tests. It shows that the efficiency degree varies with commodity, region and temporal horizon. Further, it carries out bivariate portfolio simulations in order to illustrate diversification opportunities and identify optimal investment strategies. In the third chapter, we look at the dynamics of risk premium in order to explain the inefficient character of commodity markets using a DCC-GARCH (1,1) model. Our findings do not reject the hypothesis of time-varying risk premium, which helps to better understand the fact that commodity markets alternate between inefficiency in the short term and efficiency in the long term

Full textOn political market, information is a key element to understand the strategies of the actors. During political campaigns, the candidates commit to honor their promises in electoral platforms and, when they are elected, they choose informational strategies to implement public policies they prefer. These two cases correspond respectively to a situation of selection adverse and hasard moral. Politicians benefit from a + natural ; informational rent which they can reinforce through informational strategies, during electoral campaigns and during a mandate. At the stage of the selection of the representatives, the electorate don't know the ideological preferences and the sincerity of the candidates. It corresponds respectively to an horizontal quality and a vertical one. We show that signalling mechanism inform citizens in an imperfect way. During a mandate, political ambiguity is a dominant strategy to implement public policies, in the purpose to conceal some private components of their utility function. In other words, as we show it in the first part of the thesis, a selection bias appear at the time of elections and a political bias appear during a mandate. In the second part, we question the conditions of a democratic control on political market. During political campaigns, citizens can filter the candidates' lying strategies as soon as they base their electoral decision on informational shortcuts, like ideology, and not on ambiguous and not credible promises. It is not rational to be ignorant, it is rational to be informed at the lower cost. In other words, citizens don't react in a mechanic way to the informational strategies in a context of selection adverse. Despite of this, the good selection ex ante doesn't guarantee the lack of shirking behavior ex post. Now, we show that there exist monitoring mechanisms with hasard moral : retrospective voting and political parties. On a temporal infinite horizon, elections form an efficient incentive, for the political leaders, to respond to the wishes of the citizens. Finally, a democratic control appears on political market, despite of the informational asymmetries, only if checks and balances and informational relay permit respectively to inform the electorate when the political decision makers shirk -mass media-, and to reveal electorate's preferences to the political leaders -collective actions

Full textRational expectation equilibrium (REE) models were considerably developed over the past 40 years. However, still relatively little has been done on their empirical applications, private signals being unobservable. We propose a new methodology, theoretically premised, to reconstitute these signals and thus perfectly infer all the information. This allows us to build the optimal informed investors’ portfolio and explore its properties through three studies. In the first paper, we show, based on a REE model, that the orders entered into the order book (supply) and the resulting equilibrium price constitute a sufficient statistic for the aggregate information set. We explain how to extract the information contained in these two data, using realized volumes (known with delay) as proxy for the supply, and to construct ex post the portfolio conditional on private information. We compare its performance with the optimal uninformed agents’ portfolio obtained ex ante from prices. In a second paper, we derive the optimal informed investors’ portfolio by investigating a different specification for the noise. Constituted in the first study by a supply exogenously provided by noise traders, we now consider that informed and uninformed investors trade amongst themselves. They are initially endowed with a random quantity of risky assets and have both risk-sharing and informational motives to trade rationally on the stock market. We demonstrate that we must use information-related volumes, determined with a measure of the probability of informed trades, instead of total volumes. Due to the constraints and complexity of this measure, we found that using total volumes constitutes the best choice, at least until a better measure is found. Finally, in a third study, we use the informed agents’ portfolio to test the conditional capital asset pricing model (CAPM), instead of a value-weighted stock index traditionally used as proxy for the market portfolio. We show that conditioning on private information allows estimating the real beta, as well as the market risk premium by isolating the information risk premium that an index is unable to distinguish
Bourlès, Renaud. "Essais sur la stabilité des accords d'assurance mutuelle." Phd thesis, Université de la Méditerranée - Aix-Marseille II, 2008. http://tel.archives-ouvertes.fr/tel-00416140.
Full textLe premier chapitre est consacré à l'analyse des conditions sous lesquelles un accord d'assurance mutuelle peut résister à l'émergence d'une compagnie privée. Modélisant les principales différences entre mutuelles et compagnies d'assurance, il complète la littérature existante en intégrant les choix d'investissement en capital des compagnies privées. Dans le cas d'agents exposés de manière homogène au risque, cette étude détermine l'unique choix optimal de la compagnie entrante ainsi que les conditions favorisant ou empêchant son apparition.
L'impact sur les accords d'assurance mutuelle d'une possible hétérogénéité sur l'exposition au risque des agents est ensuite abordé dans le deuxième chapitre. Cette analyse permet de présenter l'asymétrie d'information comme une explication possible à l'échec
de l'hypothèse de marché complet observé par la littérature empirique. Elle contribue par ailleurs à préciser l'avantage comparatif que possède l'assurance mutuelle en termes d'information.
Enfin, le troisième chapitre prolonge l'analyse des conséquences de l'hétérogénéité face au risque à travers l'étude de l'assurance de long terme. La modélisation de contrats d'assurance mutuelle dynamique permet d'appréhender l'impact de l'aléa moral sur la stabilité des contrats de long terme (face à l'assurance de court terme). L'examen de ces phénomènes met en évidence le rôle des préférences des agents, en termes de prudence et d'aversion au risque, sur la stabilité des contrats d'assurance mutuelle dynamique.
