Full textIn risk theory, the main task of the actuary is to manage the risks underwritten by the company so that, at any time, it will be able to fulfill its obligations. Risk measures are valuable tools for this purpose. In this thesis, risk measures and capital allocation methods based on the dependence between multivariate risks are studied. Also, new measures of risk and capital allocation methods are developed within the framework of multivariate portfolios with partially aggregated dependencies between risks. The introduction presents a literature review and the concepts discussed in this thesis. In the second chapter, the capital allocation based on the measure Tail Value-at- Risk (TVaR) for a portfolio of risks following multivariate distributions with continuous severities is presented. The third chapter is the study of the bivariate Value-at-Risk (VaR). The latter is studied and illustrated, according to the dependence between risks. Several results on the conditions of convexity and relative to concordance orders and bounds of this metric are set. An interesting application in insurance is also presented. The new bivariate lower and upper orthant TVaR are presented in chapter four. These measures are motivated, studied and applied to Equity Indexed Annuities associated with correlated assets. The fifth chapter presents a numerical algorithm in order to calculate lower and upper bounds for sums of random variables. The method suggested is concise and parsimonious. It also allows to compute bounds for the VaR for sums of random variables. A brief conclusion recalls the contributions of this thesis and suggests some interesting research venues in connection with topics discussed in the previous chapters.

Full textThe entry into force since January 1st, 2016 of Solvency 2, the European regulatory reform of insurance industry, is a historic event that will radically change the practices in risk management. It is based on taking into account the own risk profile and the internal view of risk through the ability to use internal models for calculating solvency capital requirement and ORSA (Own Risk and Solvency Assessment) approach for internal risk management. It makes the mathematical modeling an essential tool for a successful regulatory exercise. The risk theory must allow to support this development by providing answers to practical problems, especially those related to the dependence modeling and the choice of risk measures. In the same context, this thesis presents a contribution to improving the management of insurance risks. In four chapters we present multivariate risk measures and their application to the allocation of solvency capital. The first part of this thesis is devoted to the introduction and study of a new family of multivariate elicitable risk measures that we will call multivariate expectiles. The first chapter presents these measures and explains the different construction approaches. The multivariate expectiles verify a set of coherence properties that we also discuss in this chapter before proposing a stochastic approximation tool of these risk measures. The performance of this method is insufficient in the asymptotic levels of the expectiles thresholds. That makes the theoretical analysis of the asymptotic behavior necessary. The asymptotic behavior of multivariate expectiles is then the subject of the second chapter of this part. It is studied in a multivariate regular variations framework, and some results are given in the case of equivalent marginal tails. We also study in the second chapter of the first part the asymptotic behavior of multivariate expectiles under previous assumptions in the presence of a perfect dependence, or in the case of asymptotic independence. Finally, we propose using extreme values statistics some estimators of the asymptotic expectile in these cases. The second part of the thesis is focused on the issue of solvency capital allocation in insurance. It is divided into two chapters; each chapter consists of a published paper. The first one presents an axiomatic characterization of the coherence of a capital allocation method in a general framework. Then it studies the coherence properties of an allocation approach based on the minimization of some multivariate risk indicators. The second paper is a probabilistic analysis of the behavior of this capital allocation method based on the nature of the marginal distributions of risks and the dependence structure. The asymptotic behavior of the optimal allocation is also studied and the impact of dependence is illustrated using some selected models and copulas. Faced to the significant presence of dependence between the various risks taken by insurance companies, a multivariate approach seems more appropriate to build responses to the various issues of risk management. This thesis is based on a multidimensional vision of risk and proposes some multivariate risk measures that can be applied to several actuarial issues of a multivariate nature

Full textSystemic risk is a risk that can compromise the survival of the financial system. Systemic risk refers to the spread of a single bank failure to other banks. What are the measures and determinants of systemic risk? This thesis proposes an investigation of this transversal question through three chapters. The first chapter gives an overview of the various measures of systemic risk, identifies commonalities and differences and specifies the interest of each measure. The issue is the correlation between the stress test results and the various measures of systemic risk. The second chapter studies the concept of Asset Commonality as a new measure of systemic risk. The third chapter examines the relationship between different measures of systemic risk and corporate social responsibility. The empirical results show that -1- the stress test results should be supplemented by an evaluation of the systemic risk measures, -2- Asset Commonality could be considered as a complementary tool to assess the systemic risk, -3- the corporate social responsibility of financial institutions is important in order to reduce systemic risk

Full textThis PhD thesis focuses on the estimation of some risk measures for a real random variable Y with a covariate vector X. For that purpose, we will consider that the random vector (X,Y) is elliptically distributed. In a first time, we will deal with the quantiles of Y given X=x. We thus firstly investigate a quantile regression model, widespread in the litterature, for which we get theoretical results that we discuss. Indeed, such a model has some limitations, especially when the quantile level is said extreme. Therefore, we propose another more adapted approach. Asymptotic results are given, illustrated by a simulation study and a real data example.In a second chapter, we focus on another risk measure called expectile. The structure of the chapter is essentially the same as that of the previous one. Indeed, we first use a regression model that is not adapted to extreme expectiles, for which a methodological and statistical approach is proposed. Furthermore, highlighting the link between extreme quantiles and expectiles, we realize that other extreme risk measures are closely related to extreme quantiles. We will focus on two families called Lp-quantiles and Haezendonck-Goovaerts risk measures, for which we propose extreme estimators. A simulation study is also provided. Finally, the last chapter is devoted to the case where the size of the covariate vector X is tall. By noticing that our previous estimators perform poorly in this case, we rely on some high dimensional estimation methods to propose other estimators. A simulation study gives a visual overview of their performances

Full textThis thesis deals with the copulas in order to measure the market risk. Chapter 1, we recall the Most important results concerning copulas : definition, Sklar's theorem, constructions, tail dependence, concordance measures, and simulation's algorithms. In Chapter 2, we develop a non parametric estimation method based on tail dependence concept that we compare with the “Omnibus" estimator. We show that the choice of the best copula could be different according to the method. Then, our results show existence of co movements between Asian markets. Chapter 3, we develop dynamical methods to compute the Value at Risk and Expected Shortfall measures. The choice of the measure is discussed according to the Basle amendment. Chapter 4, we introduce the dynamical copula to calculate Value at Risk. Three tests are proposed in order to validate this computations method

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
