Book Description
Les chaînes de Markov sont des modèles probabilistes utilisés dans des domaines variés comme la logistique, l'informatique, la fiabilité, les télécommunications, ou encore la biologie et la physique-chimie. On les retrouve également dans la finance, l’économie et les sciences sociales. Cet ouvrage présente une étude approfondie des chaînes de Markov à temps discret et à temps continu avec des applications détaillées aux processus de naissance et mort et aux files d'attente. Ces applications sont illustrées par des algorithmes généraux de calcul de probabilités d'état et de distribution de temps de passage. Le développement de ces algorithmes repose sur l'utilisation de la technique d'uniformisation des chaînes de Markov qui est présentée de manière théorique et intuitive. Ce livre s'adresse aux ingénieurs et chercheurs ayant besoin de modèles probabilistes pour évaluer et prédire le comportement des systèmes qu'ils étudient ou qu'ils développent. Il est aussi très bien adapté pour un cours de master.

Book Description
La plupart des manuels de statistique traitent seulement le cas des variables indépendantes et de même loi. Or, dans les applications, les variables observées sont très souvent corrélées. Les exemples sont nombreux en physique, chimie, biologie, économie, démographie ou finance. Pour combler cette lacune, cet ouvrage étudie la modélisation mathématique des phénomènes statistiques et s'intéresse plus particulièrement à la statistique des processus. Didactique et illustré de nombreux exercices, il comporte trois parties : la statistique mathématique, basée sur la théorie de la décision et le point de vue asymptotique, la statistique des processus à temps discret (processus ARMA) et à temps continu (processus de Poisson, processus de diffusion) et des compléments de probabilités. Statistique mathématique et statistique des processus s'adresse aux étudiants de master et aux élèves des grandes écoles. L'auteur Denis Bosq est professeur émérite à l'Université Pierre et Marie Curie. Il est l'auteur de nombreux articles et livres de recherche en statistique.

Book Description
With the impact of the recent financial crises, more attention must be given to new models in finance rejecting “Black-Scholes-Samuelson” assumptions leading to what is called non-Gaussian finance. With the growing importance of Solvency II, Basel II and III regulatory rules for insurance companies and banks, value at risk (VaR) – one of the most popular risk indicator techniques plays a fundamental role in defining appropriate levels of equities. The aim of this book is to show how new VaR techniques can be built more appropriately for a crisis situation. VaR methodology for non-Gaussian finance looks at the importance of VaR in standard international rules for banks and insurance companies; gives the first non-Gaussian extensions of VaR and applies several basic statistical theories to extend classical results of VaR techniques such as the NP approximation, the Cornish-Fisher approximation, extreme and a Pareto distribution. Several non-Gaussian models using Copula methodology, Lévy processes along with particular attention to models with jumps such as the Merton model are presented; as are the consideration of time homogeneous and non-homogeneous Markov and semi-Markov processes and for each of these models. Contents 1. Use of Value-at-Risk (VaR) Techniques for Solvency II, Basel II and III. 2. Classical Value-at-Risk (VaR) Methods. 3. VaR Extensions from Gaussian Finance to Non-Gaussian Finance. 4. New VaR Methods of Non-Gaussian Finance. 5. Non-Gaussian Finance: Semi-Markov Models.

Book Description
The Papers collected in this volume are those presented at the tenth Collo quium arranged by the Societe Universitaire Europeenne de Recherches Fi nancieres (SUERF), which took place in Vienna in April 1982. The Society is supported by a large number of central banks, commercial banks, and other financial and business institutions, as well as by academics and others interested in monetary and financial problems. Since its estab lishment in 1963 it has developed as a forum for the exchange of informa tion, research results and ideas, valued by academics and practitioners in these fields, induding central bank officials and civil servants responsible for formulating and applying monetary and financial policies. A major activity of SUERF is to organise and conduct Colloquia on sub jects of topical interest to members. The titles, places and dates of previous Colloquia for which volumes of the collected Papers were published are noted on page 421. Volumes were not issued for Colloquia held at Tar ragona, Spain in October 1970 under the title "Monetary Policy and New Developments in Banking" and at Strasbourg, France in January 1972 un der the title "Aspects of European Monetary Union."

Book Description
Economists at the Bank of France analyse causes and consequences of French monetary policy and financial deregulation during the 1980s. Using the latest econometric techniques, they demonstrate a strategy that the UK is still hesitating to fully adopt. These essays, never published in English before, offer a comprehensive and authoritative analysis.

Book Description
From acclaimed economists George Akerlof and Robert Shiller, the case for why government is needed to restore confidence in the economy The global financial crisis has made it painfully clear that powerful psychological forces are imperiling the wealth of nations today. From blind faith in ever-rising housing prices to plummeting confidence in capital markets, "animal spirits" are driving financial events worldwide. In this book, acclaimed economists George Akerlof and Robert Shiller challenge the economic wisdom that got us into this mess, and put forward a bold new vision that will transform economics and restore prosperity. Akerlof and Shiller reassert the necessity of an active government role in economic policymaking by recovering the idea of animal spirits, a term John Maynard Keynes used to describe the gloom and despondence that led to the Great Depression and the changing psychology that accompanied recovery. Like Keynes, Akerlof and Shiller know that managing these animal spirits requires the steady hand of government—simply allowing markets to work won't do it. In rebuilding the case for a more robust, behaviorally informed Keynesianism, they detail the most pervasive effects of animal spirits in contemporary economic life—such as confidence, fear, bad faith, corruption, a concern for fairness, and the stories we tell ourselves about our economic fortunes—and show how Reaganomics, Thatcherism, and the rational expectations revolution failed to account for them. Animal Spirits offers a road map for reversing the financial misfortunes besetting us today. Read it and learn how leaders can channel animal spirits—the powerful forces of human psychology that are afoot in the world economy today. In a new preface, they describe why our economic troubles may linger for some time—unless we are prepared to take further, decisive action.
