Book Synopsis Extreme and Systemic Risk Analysis by : Stefan Hochrainer-Stigler
Download or read book Extreme and Systemic Risk Analysis written by Stefan Hochrainer-Stigler and published by Springer Nature. This book was released on 2020-04-06 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is about how extreme and systemic risk can be analyzed in an integrated way. Risk analysis is understood to include measurement, assessment as well as management aspects. Integration is understood as being able to perform risk analysis for extreme and systemic events simultaneously. The presented approach is based on Sklar's theorem, which states that a multivariate distribution can be separated into two parts – one describing the marginal distributions and the other describing the dependency between the distributions using a so-called copula. It is suggested to reinterpret Sklar's theorem from a system or network perspective, treating copulas as a network property and individual, including extreme, risk as elements within the network. In that way, extreme and systemic risk can be analyzed independently as well as jointly across several scales. The book is intended for a large audience, and all techniques presented are guided with examples and applications with a special focus on natural disaster events. Furthermore, an extensive literature and discussion of it are given in each chapter for the interested reader.
Book Synopsis Systemic Contingent Claims Analysis by : Mr.Andreas A. Jobst
Download or read book Systemic Contingent Claims Analysis written by Mr.Andreas A. Jobst and published by International Monetary Fund. This book was released on 2013-02-27 with total page 93 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent global financial crisis has forced a re-examination of risk transmission in the financial sector and how it affects financial stability. Current macroprudential policy and surveillance (MPS) efforts are aimed establishing a regulatory framework that helps mitigate the risk from systemic linkages with a view towards enhancing the resilience of the financial sector. This paper presents a forward-looking framework ("Systemic CCA") to measure systemic solvency risk based on market-implied expected losses of financial institutions with practical applications for the financial sector risk management and the system-wide capital assessment in top-down stress testing. The suggested approach uses advanced contingent claims analysis (CCA) to generate aggregate estimates of the joint default risk of multiple institutions as a conditional tail expectation using multivariate extreme value theory (EVT). In addition, the framework also helps quantify the individual contributions to systemic risk and contingent liabilities of the financial sector during times of stress.
Book Synopsis Quantifying Systemic Risk by : Joseph G. Haubrich
Download or read book Quantifying Systemic Risk written by Joseph G. Haubrich and published by University of Chicago Press. This book was released on 2013-01-24 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the aftermath of the recent financial crisis, the federal government has pursued significant regulatory reforms, including proposals to measure and monitor systemic risk. However, there is much debate about how this might be accomplished quantitatively and objectively—or whether this is even possible. A key issue is determining the appropriate trade-offs between risk and reward from a policy and social welfare perspective given the potential negative impact of crises. One of the first books to address the challenges of measuring statistical risk from a system-wide persepective, Quantifying Systemic Risk looks at the means of measuring systemic risk and explores alternative approaches. Among the topics discussed are the challenges of tying regulations to specific quantitative measures, the effects of learning and adaptation on the evolution of the market, and the distinction between the shocks that start a crisis and the mechanisms that enable it to grow.

Book Synopsis Extreme Value Modeling and Risk Analysis by : Dipak Dey
Download or read book Extreme Value Modeling and Risk Analysis written by Dipak Dey and published by CRC Press. This book was released on 2020-12-18 with total page 520 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme Value Modeling and Risk Analysis: Methods and Applications presents a broad overview of statistical modeling of extreme events along with the most recent methodologies and various applications. The book brings together background material and advanced topics, eliminating the need to sort through the massive amount of literature on the subject. After reviewing univariate extreme value analysis and multivariate extremes, the book explains univariate extreme value mixture modeling, threshold selection in extreme value analysis, and threshold modeling of non-stationary extremes. It presents new results for block-maxima of vine copulas, develops time series of extremes with applications from climatology, describes max-autoregressive and moving maxima models for extremes, and discusses spatial extremes and max-stable processes. The book then covers simulation and conditional simulation of max-stable processes; inference methodologies, such as composite likelihood, Bayesian inference, and approximate Bayesian computation; and inferences about extreme quantiles and extreme dependence. It also explores novel applications of extreme value modeling, including financial investments, insurance and financial risk management, weather and climate disasters, clinical trials, and sports statistics. Risk analyses related to extreme events require the combined expertise of statisticians and domain experts in climatology, hydrology, finance, insurance, sports, and other fields. This book connects statistical/mathematical research with critical decision and risk assessment/management applications to stimulate more collaboration between these statisticians and specialists.

Book excerpt: The Financial Sector Assessment Program (FSAP) took place against a backdrop of improved resilience and recovery after the crisis. Romanian banks enjoy one of the highest capitalization ratios in Europe, significantly strengthened since the crisis. NPLs have declined to 6.4 percent as of December 2017 from their peak of 21.5 percent following the crisis. Banks’ reliance on parent funding has also reduced significantly, and the share of foreign currency-denominated loans has declined. The banking sector’s profitability is strong and liquidity appears ample.
Book Synopsis Portfolio Risk Analysis by : Gregory Connor
Download or read book Portfolio Risk Analysis written by Gregory Connor and published by Princeton University Press. This book was released on 2010-03-15 with total page 400 pages. Available in PDF, EPUB and Kindle. Book excerpt: Portfolio risk forecasting has been and continues to be an active research field for both academics and practitioners. Almost all institutional investment management firms use quantitative models for their portfolio forecasting, and researchers have explored models' econometric foundations, relative performance, and implications for capital market behavior and asset pricing equilibrium. Portfolio Risk Analysis provides an insightful and thorough overview of financial risk modeling, with an emphasis on practical applications, empirical reality, and historical perspective. Beginning with mean-variance analysis and the capital asset pricing model, the authors give a comprehensive and detailed account of factor models, which are the key to successful risk analysis in every economic climate. Topics range from the relative merits of fundamental, statistical, and macroeconomic models, to GARCH and other time series models, to the properties of the VIX volatility index. The book covers both mainstream and alternative asset classes, and includes in-depth treatments of model integration and evaluation. Credit and liquidity risk and the uncertainty of extreme events are examined in an intuitive and rigorous way. An extensive literature review accompanies each topic. The authors complement basic modeling techniques with references to applications, empirical studies, and advanced mathematical texts. This book is essential for financial practitioners, researchers, scholars, and students who want to understand the nature of financial markets or work toward improving them.
Book Synopsis Measuring Systemic Risk-Adjusted Liquidity (SRL) by : Andreas Jobst
Download or read book Measuring Systemic Risk-Adjusted Liquidity (SRL) written by Andreas Jobst and published by International Monetary Fund. This book was released on 2012-08-01 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: Little progress has been made so far in addressing—in a comprehensive way—the externalities caused by impact of the interconnectedness within institutions and markets on funding and market liquidity risk within financial systems. The Systemic Risk-adjusted Liquidity (SRL) model combines option pricing with market information and balance sheet data to generate a probabilistic measure of the frequency and severity of multiple entities experiencing a joint liquidity event. It links a firm’s maturity mismatch between assets and liabilities impacting the stability of its funding with those characteristics of other firms, subject to individual changes in risk profiles and common changes in market conditions. This approach can then be used (i) to quantify an individual institution’s time-varying contribution to system-wide liquidity shortfalls and (ii) to price liquidity risk within a macroprudential framework that, if used to motivate a capital charge or insurance premia, provides incentives for liquidity managers to internalize the systemic risk of their decisions. The model can also accommodate a stress testing approach for institution-specific and/or general funding shocks that generate estimates of systemic liquidity risk (and associated charges) under adverse scenarios.
Book Synopsis Scenario Analysis in Risk Management by : Bertrand K. Hassani
Download or read book Scenario Analysis in Risk Management written by Bertrand K. Hassani and published by Springer. This book was released on 2016-10-26 with total page 162 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book focuses on identifying and explaining the key determinants of scenario analysis in the context of operational risk, stress testing and systemic risk, as well as management and planning. Each chapter presents alternative solutions to perform reliable scenario analysis. The author also provides technical notes and describes applications and key characteristics for each of the solutions. In addition, the book includes a section to help practitioners interpret the results and adjust them to real-life management activities. Methodologies, including those derived from consensus strategies, extreme value theory, Bayesian networks, Neural networks, Fault Trees, frequentist statistics and data mining are introduced in such a way as to make them understandable to readers without a quantitative background. Particular emphasis is given to the added value of the implementation of these methodologies.
Book Synopsis Assessing Risk Assessment by : Christian Hugo Hoffmann
Download or read book Assessing Risk Assessment written by Christian Hugo Hoffmann and published by Springer. This book was released on 2017-11-14 with total page 377 pages. Available in PDF, EPUB and Kindle. Book excerpt: Christian Hugo Hoffmann undermines the citadel of risk assessment and management, arguing that classical probability theory is not an adequate foundation for modeling systemic and extreme risk in complex financial systems. He proposes a new class of models which focus on the knowledge dimension by precisely describing market participants’ own positions and their propensity to react to outside changes. The author closes his thesis by a synthetical reflection on methods and elaborates on the meaning of decision-making competency in a risk management context in banking. By choosing this poly-dimensional approach, the purpose of his work is to explore shortcomings of risk management approaches of financial institutions and to point out how they might be overcome.
Book Synopsis Risk in Extreme Environments by : Vicki M. Bier
Download or read book Risk in Extreme Environments written by Vicki M. Bier and published by Routledge. This book was released on 2017-10-19 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Risk in Extreme Environments presents a wide-ranging discussion of approaches for assessing and managing extreme risks. Extreme events are not only severe, but also outside the normal range of experience of the system in question, and can include environmental catastrophe; engineering failure; financial or business meltdown; and nuclear or other extreme terrorism. The book focuses on synthesizing research results in a way that provides insights useful to decision makers, and enables them to ask probing questions about the risks faced by their organizations, identify creative solutions, and minimize the neglect of extreme risks that can come from a focus on mundane or ordinary management challenges. The book details case studies on nuclear power, infectious diseases, and global catastrophic risks, in addition to sections on risk assessment, risk management, and risk perceptions. Since effective management benefits from an interdisciplinary perspective, the chapter authors include experts in economics, engineering, geography, law, political science, psychology, sociology, and science in addition to risk analysis. Risk in Extreme Environments is an accessible and valuable resource for risk managers and other decision makers responsible for large complex business and government decisions, while also providing enough detail and references to be informative for risk analysts interested in learning more about technical aspects of the various methods.
Book Synopsis Risk Topography by : Markus Brunnermeier
Download or read book Risk Topography written by Markus Brunnermeier and published by University of Chicago Press. This book was released on 2014-10-17 with total page 286 pages. Available in PDF, EPUB and Kindle. Book excerpt: The recent financial crisis and the difficulty of using mainstream macroeconomic models to accurately monitor and assess systemic risk have stimulated new analyses of how we measure economic activity and the development of more sophisticated models in which the financial sector plays a greater role. Markus Brunnermeier and Arvind Krishnamurthy have assembled contributions from leading academic researchers, central bankers, and other financial-market experts to explore the possibilities for advancing macroeconomic modeling in order to achieve more accurate economic measurement. Essays in this volume focus on the development of models capable of highlighting the vulnerabilities that leave the economy susceptible to adverse feedback loops and liquidity spirals. While these types of vulnerabilities have often been identified, they have not been consistently measured. In a financial world of increasing complexity and uncertainty, this volume is an invaluable resource for policymakers working to improve current measurement systems and for academics concerned with conceptualizing effective measurement.
Book Synopsis Measuring Systemic Risk by : Deyan Radev
Download or read book Measuring Systemic Risk written by Deyan Radev and published by Springer Nature. This book was released on 2022-02-07 with total page 94 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides a comprehensive methodology to measure systemic risk in many of its facets and dimensions based on state-of-the-art risk assessment methods. Systemic risk has gained attention in the public eye since the collapse of Lehman Brothers in 2008. The bankruptcy of the fourth-biggest bank in the USA raised questions whether banks that are allowed to become “too big to fail” and “too systemic to fail” should carry higher capital surcharges on their size and systemic importance. The Global Financial Crisis of 2008-2009 was followed by the Sovereign Debt Crisis in the euro area that saw the first Eurozone government de facto defaulting on its debt and prompted actions at international level to stem further domino and cascade effects to other Eurozone governments and banks. Against this backdrop, a careful measurement of systemic risk is of utmost importance for the new capital regulation to be successful and for sovereign risk to remain in check. Most importantly, the book introduces a number of systemic fragility indicators for banks and sovereigns that can help to assess systemic risk and the impact of macroprudential and microprudential policies.
Book Synopsis Systemic Risk by : Malcolm H.D. Kemp
Download or read book Systemic Risk written by Malcolm H.D. Kemp and published by Springer. This book was released on 2017-08-11 with total page 327 pages. Available in PDF, EPUB and Kindle. Book excerpt: Systemic Risk provides readers with a wide-ranging practical guide to systemic risk in the financial system. It challenges the notion that systemic risk is exclusively about interconnectivities within the financial system, showing that past systemic risk crises have often involved a broader range of vulnerabilities. It describes how regulators and governments are seeking to manage systemic risk, and how their concerns are driving change in regulatory and business environments across the financial sector. It sets out how firms and practitioners can effectively respond to these changes (covering topics such as data needs, quantification of risk exposures, management disciplines and skillset requirements etc.). It highlights the sources and characteristics of systemic risk and the concentrations of exposures to this risk. It also links systemic risk with other risk disciplines including exploring how systemic risk ties in with liquidity risk and credit risk and how it interacts with central clearing, collateralisation and pricing of derivatives.

Available in PDF, EPUB and Kindle. Book excerpt: Focusing on financial institutions in isolation during the 2007-2009 financial crisis resulted in a serious underestimation of the wider systemic risk in play. Systemic Risk Assessment and Oversight addresses this analytical gap by outlining a bottom-up portfolio approach to systemic risk, allowing you to fully understand, analyse and prepare for this pervading risk.
Book Synopsis Review of the Department of Homeland Security's Approach to Risk Analysis by : National Research Council
Download or read book Review of the Department of Homeland Security's Approach to Risk Analysis written by National Research Council and published by National Academies Press. This book was released on 2010-10-10 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: The events of September 11, 2001 changed perceptions, rearranged national priorities, and produced significant new government entities, including the U.S. Department of Homeland Security (DHS) created in 2003. While the principal mission of DHS is to lead efforts to secure the nation against those forces that wish to do harm, the department also has responsibilities in regard to preparation for and response to other hazards and disasters, such as floods, earthquakes, and other "natural" disasters. Whether in the context of preparedness, response or recovery from terrorism, illegal entry to the country, or natural disasters, DHS is committed to processes and methods that feature risk assessment as a critical component for making better-informed decisions. Review of the Department of Homeland Security's Approach to Risk Analysis explores how DHS is building its capabilities in risk analysis to inform decision making. The department uses risk analysis to inform decisions ranging from high-level policy choices to fine-scale protocols that guide the minute-by-minute actions of DHS employees. Although DHS is responsible for mitigating a range of threats, natural disasters, and pandemics, its risk analysis efforts are weighted heavily toward terrorism. In addition to assessing the capability of DHS risk analysis methods to support decision-making, the book evaluates the quality of the current approach to estimating risk and discusses how to improve current risk analysis procedures. Review of the Department of Homeland Security's Approach to Risk Analysis recommends that DHS continue to build its integrated risk management framework. It also suggests that the department improve the way models are developed and used and follow time-tested scientific practices, among other recommendations.
