Understanding and Managing Model Risk: A Practical Guide for Quants, Traders and Validators (The Wiley Finance Series) - Tapa dura

Understanding and Managing Model Risk: A Practical Guide for Quants, Traders and Validators brings together a wide range of detailed real world examples, quantitative analysis and regulatory issues. It investigates the interaction between mathematics and the reality of markets, including the explanation of model errors and misunderstandings, providing readers with the operative indications and practical insight to help mitigate the likelihood of model losses.

Taking an operative as opposed to a bureaucratic approach to model validation, the book:

• Examines the risks arising from the use of models in calibration, pricing, hedging, correlation modelling, extrapolation and statistical arbitrage.
• Tackles modern day modelling issues including funding and market liquidity, CSA discounting, basis risk, counterparty risk, approximation errors, regulatory uncertainties and stress-testing.
• Investigates consensus models and how consensus can suddenly break down.
• Explores in detail examples from interest rate, credit and hybrid markets, covering also equity and cross-currency risks.
• Analyzes and compares a range of models including stochastic and local volatility, jumps, Libor and SABR models, copulas, structural and reduced-form models.

Understanding and Managing Model Risk offers an in-depth understanding of the financial implications of mathematical assumptions, and provides the right tools to identify, quantify and manage the risks inherent in the use of quantitative models.
