Download or read book Understanding and Managing Model Risk written by Massimo Morini and published by John Wiley & Sons. This book was released on 2011-10-20 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: A guide to the validation and risk management of quantitative models used for pricing and hedging Whereas the majority of quantitative finance books focus on mathematics and risk management books focus on regulatory aspects, this book addresses the elements missed by this literature--the risks of the models themselves. This book starts from regulatory issues, but translates them into practical suggestions to reduce the likelihood of model losses, basing model risk and validation on market experience and on a wide range of real-world examples, with a high level of detail and precise operative indications.

Available in PDF, EPUB and Kindle. Book excerpt: This dissertation comprises three papers on the governance of corporate risk: 1. The first paper investigates the role of organizational structures aimed at monitoring corporate risk. Proponents of risk-related governance structures, such as risk committees or Enterprise Risk Management (ERM) programs, assert that risk monitoring adds value by ensuring that corporate risks are managed. An alternative view is that such governance structures are nothing more than window-dressing created in response to regulatory or public pressure. Consistent with the former view, I find that, in the period between 2000 and 2006, firms with more observable risk oversight structures exhibit lower equity and credit risk than firms with fewer or no observable risk oversight structures. I also provide evidence that firms with more observable risk oversight structures experienced higher returns during the worst days of the 2007-2008 financial crisis and were less susceptible to market fluctuations than firms with fewer or no observable risk oversight structures. Finally, I find that firms without observable risk oversight structures experienced higher abnormal returns to recent legislative events relating to risk management than firms with observable risk oversight structures. 2. The most common empirical measure of managerial risk-taking incentives is equity portfolio vega (Vega), which is measured as the dollar change in a manager's equity portfolio for a 0.01 change in the standard deviation of stock returns. However, Vega exhibits at least three undesirable features. First, Vega is expressed as a dollar change. This implicitly assumes that managers with identical Vega have the same incentives regardless of differences in their total equity and other wealth. Second, the small change in the standard deviation of returns used to calculate Vega (i.e., 0.01) yields a very local approximation of managerial risk-taking incentives. If an executive's expected payoff is highly nonlinear over the range of potential stock price and volatility outcomes, a local measure of incentives is unlikely to provide a valid assessment of managerial incentives. Third, Vega is measured as the partial derivative of the manager's equity portfolio with respect to return volatility. This computation does not consider that this partial derivative also varies with changes in stock price. The second paper develops and tests a new measure of managerial risk-taking equity incentives that adjusts for differences in managerial wealth, considers more global changes in price and volatility, and explicitly considers the impact of stock price and volatility changes. We find that our new measure exhibits higher explanatory power and is more robust to model specification than Vegafor explaining a wide range of measures of risk-taking behavior. 3. The third paper examines the relation between shareholder monitoring and managerial risk-taking incentives. We develop a stylized model to show that shareholder monitoring mitigates the effect of contractual risk-taking incentives on the manager's actions. Consistent with the model, we find empirically that the positive association between the CEO's contractual risk-taking incentives and risk-taking behavior decreases with the level of shareholder monitoring. Furthermore, consistent with the board anticipating and optimally responding to shareholder monitoring, boards of firms exposed to more intense monitoring design compensation contracts that provide higher incentives to take risks. Overall, our results suggest that, when evaluating risk-taking incentives provided by a compensation contract, it is important to account for the firm's monitoring environment.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: An extensive amount of evolving guidance and rules are provided to banks by financial regulators. A particular set of instructions outline requirements to calculate and set aside loss-absorbing regulatory capital to ensure the solvency of a bank. Mathematical models are typically used by banks to quantify sufficient amounts of capital. In this thesis, we explore areas that advance our knowledge in regulatory risk management. In the first essay, we explore an aspect of operational risk loss modeling using scenario analysis. An actuarial modeling method is typically used to quantify a baseline capital value which is then layered with a judgemental component in order to account for and integrate what-if future potential losses into the model. We propose a method from digital signal processing using the convolution operator that views the problem of the blending of two signals. That is, a baseline loss distribution obtained from the modeling of frequency and severity of internal losses is combined with a probability distribution obtained from scenario responses to yield a final output that integrates both sets of information. In the second essay, we revisit scenario analysis and the potential impact of catastrophic events to that of the enterprise level of a bank. We generalize an algorithm to account for multiple level of intensities of events together with unique loss profiles depending on the business units effected. In the third essay, we investigate the problem of allocating aggregate capital across sub-portfolios in a fair manner when there are various forms of interdependencies. Relevant to areas of market, credit and operational risk, the multivariate shortfall allocation problem quantifies the optimal amount of capital needed to ensure that the expected loss under a convex loss penalty function remains bounded by a threshold. We first provide an application of the existing methodology to a subset of high frequency loss cells. Lastly, we provide an extension using copula models which allows for the modeling of joint fat-tailed events or asymmetries in the underlying process.

This book was released on 2007-03-15 with total page 698 pages. Available in PDF, EPUB and Kindle. Book excerpt: There have been major developments in the field of statistics over the last quarter century, spurred by the rapid advances in computing and data-measurement technologies. These developments have revolutionized the field and have greatly influenced research directions in theory and methodology. Increased computing power has spawned entirely new areas of research in computationally-intensive methods, allowing us to move away from narrowly applicable parametric techniques based on restrictive assumptions to much more flexible and realistic models and methods. These computational advances have also led to the extensive use of simulation and Monte Carlo techniques in statistical inference. All of these developments have, in turn, stimulated new research in theoretical statistics.This volume provides an up-to-date overview of recent advances in statistical modeling and inference. Written by renowned researchers from across the world, it discusses flexible models, semi-parametric methods and transformation models, nonparametric regression and mixture models, survival and reliability analysis, and re-sampling techniques. With its coverage of methodology and theory as well as applications, the book is an essential reference for researchers, graduate students, and practitioners.

Available in PDF, EPUB and Kindle. Book excerpt: This book is based on the Ph.D. thesis "Essays on Qualitative and Quantitative Risk Management" written by the author of this book. It consists out of three essays on text mining applications in finance and the validation of a credit risk model. To be more precise, the three essays address the following research questions: What kind of text mining measures are suitable in the finance area for analyzing text such as annual reports and can we use these measures to predict short-term performance or the reporting quality? Can we measure the tone of a document by using automatically calculated sentiment scores? How can we build a sentiment score, that captures keywords within a larger context? Do the chapters/sections of an annual report have a different influence on the whole content of the report? How can banks validate their credit risk model with a special focus on an analytical model? This book addresses practitioners, consultants, analysts, and bankers as well as students, researchers, and lecturers with focus on text mining applications in finance and the validation of credit risk models.

Download or read book Essays in Risk Modeling Asset Pricing and Network Measurement in Finance written by Bixi Jian and published by . This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Modelling financial interconnections and forecasting extreme losses are crucial for risk management in financial markets. This thesis studies multivariate risk spillovers at the high-dimensional market network level, as well as univariate extreme risk modelling at the asset level. The first chapter proposes a novel time series econometric method to measure high-dimensional directed and weighted market network structures. Direct and spillover effects at different horizons, between nodes and between groups, are measured in a unified framework. Using a similar network measurement framework, the second chapter investigates the relationship between stock illiquidity spillovers and the cross-section of expected returns. I find that central industries in illiquidity transmission networks earn higher average stock returns (around 4% per year) than other industries.The third chapter proposes a new Dynamic Stable GARCH model, which involves the use of stable distribution with time-dependent tail parameters to model and forecast tail risks in an extremely high volatility environment. We can differentiate extreme risks from normal market fluctuations with this model." --
