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
Guéniche, Alain. "Dérivation empirique du portefeuille optimal des investisseurs informés et test du MEDAF conditionnel." Thesis, Université Grenoble Alpes (ComUE), 2016. http://www.theses.fr/2016GREAG017.
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.

Full textThis thesis focusses on the problematic of the efficiency of intermediate finance on the economic growth and development processes. It concerned, on one hand, the resolution of inefficiency problems resulting from the presence of asymmetric information and uncertainty involved credit markets when reputational mechanisms implemented through banks-borrowers long-term relationships are used and, on the other hand, the conditions in which these mechanisms could emerged and expanded, in particular in a developing country such as Cameroon.The thesis thus has, at the same time, conceptual, empirical and normative purpose First of all, we tried to enrich the theoretical debate about relevance and interest of the reputational mechanism relating banking intermediation process. We show that, while in the models of agency where judicial penalties and pressures mechanisms are often ineffective and expensive, only the auto-enforceable character of the reputational mechanism is enough to guarantee its efficacious functioning. Furthermore, for us, the reputational mechanism seems better to reconcile the two usual opposite conceptions of agents behaviors that are homoeconomicus and homosociologicus. Therefore, this mechanism might constitute an interesting analysis framework for modeling banking behavior, in particular in the context of African economies where uncertainties remain aggravated and where much more economic rationalities based on the values prevail.Secondly, our statistical survey issues clearly shows that in Cameroon, with regard to decentralized financial institutions (DFIs) like Microfinance unities, formal financial institutions (FFI) seem to attach less importance to reputational practices in their capital allowance behaviour, especially to small and medium-sized enterprises (SMEs). This is likely to provide a better explanation of the differential micro-economic performance, situated here to the advantage of DFI.Finally, the same above mentioned survey strongly reveal the existence of many both internal and external factors preventing both categories of banks in a better consideration of reputational mechanisms. We then proposed axes or lines of reflection, formulated and justified a set of corporate, institutional and regulatory associated recommendations. This with the aim to build a more reliable and more solid Cameroonian banking system by inciting banks to better integrate reputational practices in their judgment of granting credits to borrowers
Adoukonou, Olivier Yvon. "Convertible bonds financing : Shareholder wealth effects, Sequential Investments and Call Policies." Thesis, Rennes 1, 2016. http://www.theses.fr/2016REN1G028/document.
Full textThis thesis focuses on three aspects of convertible bonds financing using a Western European sample between 1994 and 2016. The first study of this thesis is related to the shareholder wealth effects at the announcement of the convertible bonds issuance during financial crises. We find that the market reaction is more negative during crises’ periods compared to that in normal periods. Analysis of the determinant of this reaction indicates that the market recognizes the potential of convertible bonds to reduce agency and adverse selection costs. However, we also find that the signal of overvaluation sent by the issuance mitigates the investors’ optimism about the ability of the convertible bonds to alleviate external financing costs and this bad signal is exacerbated during the financial crises. Furthermore, we find that firms that are short-sale constrained incur less negative market reaction. The second study tests the sequential financing theory of Mayers (1998) which supports that firms issue callable convertible bonds in order to implement optimal sequential financing strategy. We point out in this study the importance of the call provision by comparing the investment and financing activities of Western European firms that early called their convertible bonds to those in the same industry that redeemed their bonds at maturity. We find that the inclusion of such provision allows firms (callable convertible bonds issuers) to better control issuance costs and signals a “strong” sequential financing strategy. We also find that the calling firms invest more than the non-calling firms at the call date and the difference-in-differences model shows that this difference is due to the call decision, after controlling for time fixed effects and other control variables. The last chapter of this thesis addresses the issue of convertible bonds call delay. As previous studies, we find that the companies do not call their bond at the optimum point identified by Ingersoll (1977). Unlike previous researches in the same area, our study considers the main theoretical rationales for convertible bonds call delay. We find strong evidence for the financial distress hypothesis, little evidence for cash flow advantage and signaling theories but no evidence for the notice period justification

Full textThis thesis studies the role of third parties in tempering informational issues at stake with regard to corporate social responsibility (CSR). Firms growingly claim to be adopting responsible practices, and it may be so because some socially conscious stakeholders (e.g. consumers, investors) are ready to reward such behaviors. Nevertheless, truthfulness of firms' virtue claims is often impossible or at least difficult to ascertain, which creates an incentive for firms to manipulate their communication. This dissertation intends to analyse how third parties can temper this asymmetry of information. Organisms such as rating agencies, non-governmental organisations, labeling institutions, can investigate firms' real actions and convey this information to stakeholders. These third parties have heterogeneous informational behaviors: some of them mostly disclose information on firms that do not behave responsibly while others are specialized in revealing firms that are socially or environmentally responsible. We develop a simple theoretical model that explores the provision of quality by a firm under friendly informational environments, in which quality is more often disclosed when it is high than when it is low, and hostile environments, in which the converse holds. We apply this base model to two types of third party: NGOs and labels. We endogenize the production of good and bad news in order to understand when and why NGOs choose between being hostile or friendly. Then, we seek to assess what is the more efficient level of label's strictness to spur social welfare and investment in high quality
Baalbaki, Shibly Fatima. "Three essays on the effects of the simultaneous adoption of IFRS (International Financial Reporting Standards) and MAD (Market Abuse Directive) in Europe." Thesis, Grenoble, 2014. http://www.theses.fr/2014GRENG011.
Full textWhile prior research on mandatory IFRS adoption fails to provide evidence of improvement in the quality of financial reporting (increased transparency and/or comparability), it provides almost unanimous evidence of beneficial capital-market impacts. Within the European Union (EU), mandatory IFRS adoption coincides with the adoption of the Market Abuse Directive (MAD). While the mandatory adoption of IFRS took place in 2005, MAD was passed between 2004 and 2007 depending on the EU country under consideration. Furthermore, both IFRS and MAD aim towards increased transparency, either by improving the quality of financial reporting (IFRS) or by prohibiting selective disclosures to enhance common information available to all market participants (MAD). Our first essay aims to disentangle the respective market impacts of MAD adoption and IFRS adoption in order to determine the specific effect of each regulation. Our evidence suggests that a significant part of the capital market effects usually attributed to IFRS comes, at least to some extent, from the contemporaneous adoption of the Market Abuse Directive. Our second essay focuses on the role of information environment. Investigating how information environment affects the market impacts of both MAD adoption and IFRS adoption is crucial to determine whether all firms benefit identically from these regulations. Using firm size and analyst following as proxies capturing firms' information environment, we provide evidence showing that small firms and firms with weak analyst following are those that benefit the most from the introduction of the IFRS mandate. In contrast, large firms and firms with high analyst coverage benefit the most from MAD adoption. Our third essay analyzes the role of enforcement. We find that the effectiveness of both IFRS and MAD is hampered by different enforcement levels across firms and countries. Moreover, the observed capital-market outcomes on one regulation differ if the effects of both regulations are not clearly dissociated. Thus, we caution researchers not to attribute capital-market outcomes primarily or solely to one regulation without taking into account the concomitant adoption of the other one

Full textTechnological innovation is considered as a key element in the knowledge-based economies, where the share of intangible assets continues to grow significantly. The development of innovation is enhanced mainly in the purpose of value creation and the obtaining of a competitive advantage. Nevertheless, innovating is a long process where the lag between the investments in Research and Development (R&D) activities, considered as its input, and the obtaining of a valuable output, often estimated by the patent application, is large. The long character is emphasized by the uncertainty and the riskiness of the process which are at the root of important problems of information asymmetry between investors and the insiders. This dissertation studies the impact of intangible investments on the financial performance of companies in Europe. Therefore, we use a unique database of European patents and suggest a set of qualitative measures to innovation, based on the patents’ attributes. Moreover, this thesis estimates the market value of intangibles as measured by the R&D expenses, the patent applications but also the qualitative attributes. In this framework, we construct a composite quality index of innovation in order to better estimate its private economic value. The increasing lag between financial and book values in the presence of R&D investments leads us to undertake a causal study of innovation on the financial performance of companies. We suggest our composite index as non-financial metric to predict the future earnings and examine the effect of R&D on the growth and volatility of future operating incomes
