The book "Copula Methods in Finance" by Umberto Cherubini, Elisa Luciano, and Walter Vecchiato, published by John Wiley & Sons, Ltd., provides a comprehensive introduction to the use of copula functions in financial applications. Copula functions are a powerful tool for modeling the dependence structure between financial variables, particularly in the context of non-normal distributions and market comovements. The book is structured into several chapters that cover various aspects of copula methods in finance: 1. **Derivatives Pricing, Hedging, and Risk Management**: This chapter reviews the state of the art in asset pricing and risk management, highlighting the limitations of traditional models like the Black-Scholes model due to the non-normal distribution of financial returns. It introduces the concept of copula functions and their potential to address these issues. 2. **Bivariate Copula Functions**: This chapter delves into the mathematical and probabilistic background of copula functions, providing examples and applications in finance. It covers the definition, properties, and applications of bivariate copula functions. 3. **Market Comovements and Copula Families**: This chapter discusses the flaws of linear correlation and how copula functions can provide a more flexible way to model market comovements. It explores different parametric families of bivariate copulas and their applications. 4. **Multivariate Copulas**: This chapter extends the concepts to multivariate settings, covering the definition, properties, and applications of multivariate copula functions. It also discusses the estimation and calibration of copula models from market data. 5. **Estimation and Calibration from Market Data**: This chapter explains statistical inference for copulas, including classical and recent estimation methods such as exact maximum likelihood, the IFM method, and the CML method. It also covers non-parametric estimation techniques and the calibration of copula models using sample dependence measures. 6. **Simulation of Market Scenarios**: This chapter is dedicated to simulation algorithms for multivariate copulas, providing practical examples and financial applications. 7. **Credit Risk Applications**: This chapter applies copula methods to credit risk analysis, including the pricing of complex credit structures like basket default swaps and CDOs. It discusses the calibration of pricing models to market data and the sensitivity of these models to different copula choices. 8. **Option Pricing with Copulas**: This chapter covers the use of copula functions in option pricing, including the pricing of bivariate options, vulnerable options, rainbow options, barrier options, and multivariate basket options. It also discusses the estimation and simulation techniques for these problems. The book aims to provide readers with a solid understanding of copula functions and their applications in financial modeling, making it a valuable resource for both academics and practitioners in the field of finance.The book "Copula Methods in Finance" by Umberto Cherubini, Elisa Luciano, and Walter Vecchiato, published by John Wiley & Sons, Ltd., provides a comprehensive introduction to the use of copula functions in financial applications.
