Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The industrial organisation literature typically assumes ex-ante utility functions to quantify the network effects of the various industries it models. In this book we present a simple analytical model which uses an explicit graph-theoretic modelling to simulate these network effects. The network effects it describes are fairly general since they are a mix of pure network effects - being able to link to more agents - and of potential cost-reductions stemming from decreasing marginal costs of the network infrastructure. The model can be applied to a variety of situations, such as telecommunication networks, the current Central Security Depositories network of cross-border links, or, alternatively, its associated custodian network. We derive close-forms of a (quadratic) network effect from the model. In particular it allows to quantify the advantage of a given individual to join a given network, and to split up analytically the various benefits expected from the network. We derive closed-form formulas in the case of homogeneous network and present the algorithms needed for Monte-Carlo simulations for the non-homogeneous case. 68 pp. Englisch.…

Paperback. Condizione: new. Paperback. This book focuses on the estimation and modelling of defaults, both for firms and for specific types of loans and debt instruments. It provides a comprehensive overview of the default models most widely used in finance and risk management in a self-contained way, with consistent notations across the various models, revealing the links between models as well as each model's use, limitations and extensions. The book also presents two new and less well-known promising types of models for estimating and predicting defaults. The two models are tested in this book using data on the performance of Spanish small and medium sized (SME) loans in Asset Backed Securities (ABS), in particular loan-level data stored in the European Data Warehouse. The first type of innovative model borrows techniques from the speech recognition literature to estimate the credit cycle of a particular sector of the economy based on a time series of realised defaults. Our results confirm that most sectors go through "credit cycles", which can be distinct from business cycles and estimated independently from traditional macro-economic variables if long-enough time series of realised defaults are available. Within each phase of the cycle (low default risk / high default risk), the model is able to efficiently estimate different probability of defaults for loans belonging to that sector, using data from Bloomberg. The required efficient algorithms are provided in an annex and are crucial to the implementation of the model, as direct computation is not achievable. The second type of innovative model borrows techniques from survival analysis literature to allow for more granular default probability estimations, using loan-level data from Spanish SME ABS transactions. Our model uses rigorous statistical methods traditionally used in medicine, but largely unknown in finance, to produce loan-specific relative risk assessments, leveraging the very large data set to achieve granular estimations. We estimated risk scores that quantify each characteristic of an individual loan in terms of how much it increases the probability of default, holding all other characteristics, as well as some selected macro-economic variables, constant. Of all the loan characteristics that were tested, we find that the loan purpose is the most relevant for the risk of default, with "debt-consolidation" increasing twofold the rate of default compared to loans whose purpose was for investment, i.e. "purchase of equipment". The legal form, the borrower's Basel 3 segment, the type of collateral used, as well as the initial interest spread charged to the borrower at origination of the loan, are also crucial explanatory variables in Spanish SME loan riskiness, with the impact on the default rate being of a similar magnitude than a 1% variation of the Gross-Domestic Product (GDP).

Paperback. Condizione: new. Paperback. Se souvenir des belles choses. est le recit d'un petit cancre d'ecole devenu, a la sueur de son front, un responsable d'atelier de carrosserie-peinture. De ses premiers jouets repeints par ses soins a la peinture complete d'un helicoptere valant plusieurs millions, ce livre relate vingt annees de services dans l'automobile et offre un regard sincere sur les relations humaines dans le cadre de cette profession. Il prouve egalement qu'a force de convictions, d'efforts et de travail un petit cancre peut lui aussi reussir dans la vie ! This item is printed on demand.

Taschenbuch. Condizione: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Stanley propose en 1981 un nouveau problème de reconstruction pour les graphes non-orientés. Switcher en un sommet consiste à remplacer toutes les arêtes incidentes à ce sommet par des non-arêtes et vice-versa. Dans la première partie nous présenterons de nouveaux problèmes de reconstruction qui s'inspirent de, et généralisent, celui de Stanley, ainsi qu'une méthode qui permet d'établir des résultats similaires à ceux obtenus par Stanley, Ellingham et Royle, et Krasikov et Roditty dans le cas du problème de Stanley, en particulier un Lemme 'à la Kelly'. Dans la seconde partie nous présentons la conjecture de Hahn et Jackson, qui s'insère dans le cadre de l'étude des relations entre stables et chemins dans les graphes orientés. Hahn et Jackson conjecturent que pour tout entier naturel k, il existe un graphe de stabilité k tel que quelques soient les k-1 chemins que l'on supprime (avec leurs sommets) du graphe, la cardinalité du graphe obtenu reste k. Cette conjecture est aussi forte que possible. Nous construisons explicitement une famille infinie de tels graphes, pour tout k de la forme 2^n.3^m, où n et m sont deux entiers naturels. 180 pp. Französisch.…
