Building upon the ideas introduced in their previous book, Derivatives in Financial Markets with Stochastic Volatility, the authors study the pricing and hedging of financial derivatives under ...stochastic volatility in equity, interest-rate, and credit markets. They present and analyze multiscale stochastic volatility models and asymptotic approximations. These can be used in equity markets, for instance, to link the prices of path-dependent exotic instruments to market implied volatilities. The methods are also used for interest rate and credit derivatives. Other applications considered include variance-reduction techniques, portfolio optimization, forward-looking estimation of CAPM 'beta', and the Heston model and generalizations of it. 'Off-the-shelf' formulas and calibration tools are provided to ease the transition for practitioners who adopt this new method. The attention to detail and explicit presentation make this also an excellent text for a graduate course in financial and applied mathematics.

The financial industry's invention of complex products such as credit default swaps and other derivatives has been widely blamed for triggering the global financial crisis of 2008. Codes of Finance ...takes readers behind the scenes of the equity derivatives business at one of the world's leading investment banks before the crisis, providing a detailed firsthand account of the creation, marketing, selling, accounting, and management of these financial instruments--and of how they ultimately created havoc inside and outside the bank.
Who are the agents of financial regulation? Is good (or bad) financial governance merely the work of legislators and regulators? Here Annelise Riles argues that financial governance is made not just ...through top-down laws and policies but also through the daily use of mundane legal techniques such as collateral by a variety of secondary agents, from legal technicians and retail investors to financiers and academics and even computerized trading programs. Drawing upon her ten years of ethnographic fieldwork in the Japanese derivatives market, Riles explores the uses of collateral in the financial markets as a regulatory device for stabilizing market transactions. How collateral operates, Riles suggests, is paradigmatic of a class of low-profile, mundane, but indispensable activities and practices that are all too often ignored as we think about how markets should work and be governed. Riles seeks to democratize our understanding of legal techniques, and demonstrate how these day-to-day private actions can be reformed to produce more effective forms of market regulation.
Regulators, much like market actors, rely on categorical distinctions. Innovations that are ambiguous to regulatory categories but not to market actors present a problem for regulators and an ...opportunity for innovative firms. Using a wide range of primary and secondary, qualitative and quantitative sources, we trace the history of one class of innovative financial derivatives—interest rate and foreign exchange swaps—to show how these instruments undermined the separation of commercial and investment banking established by the Glass-Steagall Act of 1933 even as overt political action failed to do so. Swaps did not fit neatly into existing product categories—futures, securities, loans—and thus evaded regulatory scrutiny for many years. The market success of swaps put commercial and investment banks into direct competition and, in so doing, undermined Glass-Steagall. Drawing on this case, we theorize that ambiguous innovations may disrupt the regulatory status quo and shift the political burden onto parties that want to maintain existing regulations. Our findings also suggest that category-spanning innovations may be more valuable to market participants if regulators find them difficult to interpret.
This paper asks how far performativity in the Green Economy generates material or virtual assets. It examines the relationship between assets and their financial derivatives, asking how far the value ...of 'carbon' or 'green' can be directly attributed to its social and narrative construction. The paper draws on two case studies - one of the Clean Development Mechanism (CDM) in South Africa, the other of the global private green bonds market - to show that both public and private climate finance can generate virtual economic activity co-produced by processes of social valuation and accumulation proper. How reliant is the Green Economy on actual economic activity?
Finance provides a dramatic example of the successful application of advanced mathematical techniques to the practical problem of pricing financial derivatives. This self-contained 2002 text is ...designed for first courses in financial calculus aimed at students with a good background in mathematics. Key concepts such as martingales and change of measure are introduced in the discrete time framework, allowing an accessible account of Brownian motion and stochastic calculus: proofs in the continuous-time world follow naturally. The Black-Scholes pricing formula is first derived in the simplest financial context. The second half of the book is then devoted to increasing the financial sophistication of the models and instruments. The final chapter introduces more advanced topics including stock price models with jumps, and stochastic volatility. A valuable feature is the large number of exercises and examples, designed to test technique and illustrate how the methods and concepts can be applied to realistic financial questions.
Valuation and hedging of financial derivatives are intrinsically linked concepts. Choosing appropriate hedging techniques depends on both the type of derivative and assumptions placed on the ...underlying stochastic process. This volume provides a systematic treatment of hedging in incomplete markets. Mean-variance hedging under the risk-neutral measure is applied in the framework of exponential Lévy processes and for derivatives written on defaultable assets. It is discussed how to complete markets based upon stochastic volatility models via trading in both stocks and vanilla options. Exponential utility indifference pricing is explored via a duality with entropy minimization. Backward stochastic differential equations offer an alternative approach and are moreover applied to study markets with trading constraints including basis risk. A range of optimal martingale measures are discussed including the entropy, Esscher and minimal martingale measures. Quasi-symmetry properties of stochastic processes are deployed in the semi-static hedging of barrier options.
This edited volume will highlight recent research in derivatives modelling and markets in a post-crisis world across a number of dimensions or themes. The book addresses the following main areas: ...derivatives models and pricing, model application and performance backtesting, new products and market features. Particular themes encompass: - continuous and discrete time modeling, - statistical arbitrage models, - arbitrage-free pricing, risk-neutral implied densities, - equilibrium pricing approaches (including e.g. co-integration), - applications of methods in computational statistics including simulation, - computationally intense techniques for pricing, estimation and backtesting, - complex derivative products, - credit and counterparty risk, - innovative market and product structures.
