L'étude de ces problèmes est motivée par les applications dans plusieurs domaines comme la finance, l'économie ou la médecine.
La première partie est une mise en évidence du fait que le plus petit temps d'arrêt optimal est parfois un temps d'atteinte. C'est pourquoi, dans la deuxième partie de la thèse, on s'intéresse à la loi d'un temps d'atteinte d'un processus de Lévy à sauts ainsi qu'à quelques applications à la finance, plus précisément lors du calcul de l'intensité de ce temps d'arrêt associée à une certaine filtration $\F$. Deux cas sont présentés : quand le temps d'arrêt est un $\F$-temps d'arrêt et quand il ne l'est pas.

Full textThe first essay analyses the default risk related to the Mexican external debt which exhibits a structural change at the beginning of the 90’s. Different stochastic discount factors are taken into account and a comparison with market data is presented. On the second essay, credit risk is modelled by incorporating simultaneously: (a) a grace period before declaring bankruptcy (Parisian option feature), and (b) the macro economic market conditions (regime switching model). A numerical method is proposed to evaluate the model. The third essay shows how the risk of default is incorporated to the market value of assets and liabilities of a life insurance company under a regime switching model. An econometric study using life insurance data is performed, providing strong evidence of switching behaviour on the market, affecting the contingent claim valuation. Finally, a numerical method is also proposed

Full textThe default risk is the most important risk for coupon bearing bonds investors. Indeed, it represents the potential non-payment of coupon or coupon and principal by the issuers. Two + tools ; are generally used by professionals in order to measure this risk. The rating is a qualitative measure allocated by agencies such as standard and poor's or moody's. The yield spread is a quantitative measure deduced from asset prices on the financial market. This work is dedicated to the construction of modelisations integrating this potential bankruptcy of the issuer and their validations using market data. Several modelisations are proposed wich use the actuarial default spread or the dynamic evolution of zero-coupon bond prices. In an actuarial approach, we propose an original two parameter model that can be easily used to construct the default probabilities term structure using the prices of long and short term debts of the issuer. With this modelisation, we demonstrate that the actuarial default spread is positively linked to the level of interest rate. This result is in opposition to the ones obtained by other theoretical approaches (for example Leland and Toft (1996)). In another part of this work, we extend the approach for pricing bonds subject to default risk proposed by Jarrow et Turnbull (1995). Our original modeling enables the description of different types of bankruptcy in a unified modelisation. From an empirical point of view, we propose alternative original measure based on the deformation of interest rate term structure which can replace the actuarial yield default spread. Then, we test these measures using various samples of French bonds. We show that the typology induced by ratings is not reproduced in the default spreads. Only four classes of risk are necessary in order to describe the risky bond market. Finally, we study the effect of bond rating change on asset prices and we show that this change is generally anticipated by the investors

Full textThe topic of this thesis is about the optimization of portfolio of defaultable assets. The subprime crisis show us that in the future, we should deal with the default risk to get the real value of the portfolio. In fact, there are so many exchanges in the markets that the financial market become a network with many connections and we should identity it to understand the real risk that we take when we deal with financial assets. In this thesis; we define a financial system with a finite number of connections and we give a model for the dynamics of the asset in such system considering the connections in the network. We deal with the jumps intensity processes to take account the correlation in the network. Using Backward Stochastic Differential Equations (BSDE), we get the price of a contingent claim and we consider the model risk to get the optimal consumption and terminal wealth in such financial network

Full textThe problematic of this thesis is the impact of accounting information on the risk or failure and on the market risk form firms. We have showed that the financial theory is not unified about the risk of failure. We have improved the prediction of failure risk with expert system and with a new building method of discrimination model. The expert system detects some accounting handing. Therefore the statistical analysis is more reliable with the expert system. The improvement of discrimination model is the use of step by step building under two constraints (statistical and financial constraints). The risk of failure rating includes the sectorial activity and the last accounting innovation (The cash flow of R. Dornier). The model is conceived with 901 firms and tested with 5000 balance sheets belonging to SNVB customers. For firms rating on the stock exchange, we have successively realised an analytical and empirical approach to apprehend the impact of accounting information on the market risk. We pointed out in two theorical models that the evaluation of market risk may be improved by accounting variables such as the firm growth. Finally, we have showed, on a small sample (155 cases) that the impact of accounting information may be improved by mathematical fonction of jump on the share returns distributions

Full textAll bondholders have to face many kinds of investment risks, including the risk or non paiement of the capital and interest, called default paiement risk. This kind of risk can be estimated by the market or by rating organisms. The counter value of the this kind of risk is the spread, which added to a comparable (same interest rate and maturity), gives the yield of the bond. The first part of the ressearch studies the spread which is the first tool that gives information to financial communauty about the bond default risk. What are this determinants? to answer to the question, we procede this way : in the first step, we scarch the parameters which have influence on the default risk and the corresponding spread, from the existant financial studies and researchs. Then, in a second step, we monde experimental study in order to niveal the financial raitos which have an impact on the spread. The second part of the research studies the risk default as evaluated by rating organisms. The well-known are moody's an standard & poor's estalished in the u. S. A. From about one century. After a description of the rating agencies established in france and on all aver the word, we tried, accross an empirical test to search the variables which have apredictive power of default issuers, and used by the rating organisms when they note bonds. At the end we comparaed the variables which have an impact on spreads to those found as having an impact on ratings in order to see whether or not the market and rating agencies have the same evaluation of issues default risk

Full textThis thesis on empirical results in four articles focused on the determinants of the sovereign default risk. The first chapter summarizes the state of the art of sovereign default risk and the three main approaches of determinants of sovereign default risk: the structure model, the dynamic stochastic model and the econometric models. The second chapter studies the default probability in Argentina (2002) by using a structural model proposed by Gray and Malone 2008. The third chapter provides a stochastic model to calculate the daily sovereign credit spread. Last two econometric chapters determine two sovereign default risk proxies: Sovereign CDS spread and Emerging Market Bond Index Plus. The fourth chapter focuses on the sovereign CDS spread in long-run and short-run by using three estimations of Pooled Mean Group, Mean Group and Dynamic Fixed Effect. The last chapter applies a nonliear Autoregressive Distributed Lag asymmetry model to study the long-run asymmetric effect of the current account to the EMBI+ including the explanatory variables such as the external debt and international reserves for the two typical emerging countries Turkey and Brazil
